The temporal aspect of nut bearing in pecan trees is a critical factor for both commercial growers and home gardeners. It’s not a simple case of planting and immediate harvesting. Maturity, environmental conditions, and cultivar selection significantly impact the timeline of nut production. Understanding the factors influencing this timeline is essential for successful pecan cultivation.
Predicting the timeframe for the initial harvest allows for appropriate investment planning and resource allocation in orchards. For homeowners, knowing when to anticipate nuts allows for proper tree care and protection against pests and wildlife. Historically, this knowledge was passed down through generations, leading to regional variations in pecan cultivars and management practices best suited for specific climates and soil types. The economic significance of pecan production hinges on maximizing yield within a predictable timeframe.
Therefore, several elements must be considered when estimating the time required for pecan trees to begin producing nuts, including the propagation method employed, the age of the tree, and the influence of cross-pollination. These will be discussed in the following sections.
1. Grafted vs. Seedling
The propagation method, specifically whether a pecan tree is grafted or grown from seed, fundamentally influences the timeframe for nut production. Grafted trees, created by joining a scion (a twig from a known, productive variety) to a rootstock, bypass the lengthy juvenile phase inherent in seedling trees. This is because the scion already possesses the maturity of the parent tree. As a result, grafted pecan trees generally begin producing nuts within 3 to 5 years after planting. Conversely, seedling trees, grown directly from pecan nuts, require a significantly longer juvenile period, typically ranging from 7 to 10 years, and sometimes longer, before they begin to bear nuts. The inherent genetic variability of seedlings also contributes to this delayed and often unpredictable production.
Consider a commercial pecan orchard. Grafting is the standard propagation technique. The consistent and relatively rapid production of grafted trees directly impacts the economic viability of the orchard. Conversely, planting a seedling tree may be suitable for a hobbyist with ample time and less concern for immediate returns. Furthermore, the quality and characteristics of nuts from seedling trees are less predictable compared to the known attributes of grafted varieties. A ‘Pawnee’ pecan scion grafted onto a hardy rootstock, for example, will reliably produce ‘Pawnee’ pecans in a few years. A seedling, however, may yield nuts with inferior size, taste, or shell characteristics after a much longer wait.
In summary, the choice between grafted and seedling pecan trees has a profound effect on nut production timelines. Grafting accelerates the process, providing earlier and more predictable yields, vital for commercial operations. Seedling trees, while potentially viable, present longer maturation periods and uncertain nut qualities. This knowledge is crucial for anyone planning to grow pecan trees, allowing for informed decisions based on desired outcomes and time horizons.
2. Cultivar Selection
The choice of pecan cultivar significantly influences the timeframe for initial nut production. Different cultivars exhibit varying degrees of precocity, referring to the propensity to bear fruit at a relatively young age. Selecting a precocious cultivar can shorten the waiting period before harvest. Some cultivars, like ‘Pawnee’ or ‘Sumner,’ are known for their early bearing characteristics, often producing nuts within 4 to 6 years after planting as grafted trees. Conversely, other cultivars may require 7 to 10 years or more to begin bearing. This variation is due to genetic differences affecting growth rate, flowering, and nut development. Therefore, cultivar selection is a primary determinant of when nut production commences.
Consider a pecan orchard where the grower aims to maximize early returns on investment. The selection of ‘Pawnee,’ a cultivar recognized for its rapid maturity and large nut size, would be strategically advantageous. Compared to a less precocious cultivar, such as ‘Elliott,’ the ‘Pawnee’ trees would begin producing a marketable crop several years sooner, accelerating profitability. However, cultivar selection is not solely based on precocity. Factors such as disease resistance, cold hardiness, nut quality, and pollination requirements must also be considered to ensure long-term orchard health and productivity. Therefore, cultivar selection involves balancing early production with other essential traits to optimize overall performance.
In summary, cultivar selection represents a critical decision point affecting the timeframe to first harvest. Opting for precocious cultivars can substantially reduce the waiting period for nut production. Nevertheless, a holistic approach is necessary, encompassing factors beyond precocity to ensure sustainable and economically viable pecan cultivation. The informed selection of cultivars tailored to specific environmental conditions and market demands is crucial for successful pecan production.
3. Tree Maturity
Tree maturity is a critical factor determining the onset of nut production in pecan trees. Immaturity, specifically the juvenile phase, is characterized by vegetative growth prioritization over reproductive development. During this period, the tree dedicates resources to establishing a robust root system and developing its structural framework. Nut production is energetically expensive; thus, it is deferred until the tree attains sufficient size and physiological capacity to support both growth and reproduction. Premature attempts to induce fruiting can weaken the tree and compromise long-term productivity. Consequently, a pecan tree will not bear nuts until it reaches a developmental stage considered mature, signifying a shift in resource allocation towards reproductive processes.
The duration of the juvenile phase varies depending on factors such as propagation method and cultivar, as previously discussed. However, even after the juvenile phase ends, consistent nut production requires sustained tree health and vigor, indicators of continued maturity. For example, a mature pecan tree subjected to environmental stress, such as drought or nutrient deficiency, may exhibit reduced nut yield or even revert to a primarily vegetative state. Furthermore, mature trees are better equipped to withstand pest infestations and diseases, further contributing to consistent nut production. In essence, tree maturity is not a static state but an ongoing condition that must be maintained for optimal nut yields.
In conclusion, tree maturity is an indispensable prerequisite for pecan nut production. The transition from vegetative growth to reproductive development marks the beginning of the bearing phase. However, maintaining tree health and vigor remains essential for sustained yields throughout the tree’s lifespan. Understanding the physiological requirements of mature pecan trees, including water, nutrients, and pest management, is crucial for maximizing nut production and ensuring the long-term economic viability of pecan cultivation. The timeframe for the initial harvest is, therefore, inextricably linked to achieving and maintaining tree maturity.
4. Pollination Requirements
Pecan pollination is a critical determinant in the timeline of nut production. Unlike self-pollinating species, pecan trees exhibit dichogamy, a temporal separation of pollen shed and pistillate flower receptivity within the same tree. This necessitates cross-pollination between different pecan cultivars for successful fertilization and subsequent nut development. The absence of adequate pollination results in minimal or no nut production, irrespective of tree age or vigor, thus impacting the anticipated harvest timeframe.
-
Dichogamy and Cultivar Selection
Dichogamy, the staggered release of pollen and receptivity of female flowers, is pronounced in pecan trees. Protandry (pollen shed before female flower receptivity) and protogyny (female flower receptivity before pollen shed) are the two primary types. Therefore, planting compatible cultivars with overlapping pollen shed and pistillate flower receptivity periods is essential for effective cross-pollination. Failure to select appropriate pollinizer trees will extend the period before significant nut production, even if the primary cultivar is mature and healthy. For instance, planting only protandrous cultivars will yield minimal nuts, regardless of how quickly the trees reach bearing age, because the female flowers will not be adequately pollinated.
-
Wind Pollination and Tree Spacing
Pecans are primarily wind-pollinated. Effective pollination depends on sufficient pollen dispersal from pollinizer trees to the receptive female flowers of the target cultivar. Consequently, proper tree spacing is crucial to ensure adequate pollen distribution. Overly dense plantings can restrict airflow and reduce pollen dispersal, while excessively wide spacing may limit the concentration of pollen reaching the target trees. Optimal spacing is cultivar-dependent and should consider prevailing wind patterns. Improper spacing can delay significant nut production, even when compatible pollinizer trees are present, as the pollination process is inherently inefficient without proper airflow and proximity.
-
Pollen Viability and Environmental Factors
Pollen viability, the ability of pollen grains to successfully fertilize the female flower, is influenced by environmental factors, particularly temperature and humidity. Extreme temperatures or prolonged periods of high humidity can reduce pollen viability, even if compatible pollinizer trees are shedding pollen at the appropriate time. Consequently, adverse weather conditions during the pollination period can negatively impact nut set and delay the realization of anticipated yields. Selecting cultivars adapted to the local climate can mitigate some of these risks, but unpredictable weather events can still affect pollen viability and subsequent nut production.
-
Pollinator Insects and Supplemental Pollination
While pecans are primarily wind-pollinated, some studies suggest that insects, particularly bees, may play a minor role in pollen transfer. However, insect pollination is not considered a primary factor in pecan nut set. In situations where natural pollination is insufficient, supplemental pollination techniques, such as applying harvested pollen to receptive female flowers, can be employed. This is labor-intensive and generally reserved for controlled breeding programs or high-value cultivars. The necessity for and effectiveness of supplemental pollination ultimately depends on the sufficiency of natural wind pollination and the prevailing environmental conditions. If natural pollination is consistently inadequate, supplemental techniques may be required to achieve commercially viable nut production, irrespective of the tree’s age or cultivar.
In summary, effective pollination is a prerequisite for pecan nut production, irrespective of tree maturity or cultivar precocity. Dichogamy necessitates the selection of compatible pollinizer trees, while wind pollination requires appropriate tree spacing and consideration of pollen viability. Failure to address these pollination requirements will inevitably delay the onset of significant nut production, undermining the long-term productivity and economic viability of pecan cultivation. Understanding the nuances of pecan pollination is, therefore, essential for accurately predicting the timeframe for nut production and implementing management practices that promote successful fertilization.
5. Soil Fertility
Soil fertility is a foundational element influencing the timeframe for pecan nut production. Adequate nutrient availability within the soil directly impacts tree vigor, growth rate, and the capacity for reproductive development. Deficiencies in essential nutrients can delay the onset of nut bearing, reduce nut yields, and compromise overall tree health. The link between soil fertility and the timeline of pecan production is, therefore, undeniable.
-
Macronutrient Availability
Macronutrients, including nitrogen, phosphorus, and potassium, are required in substantial quantities for pecan tree growth and nut development. Nitrogen is crucial for vegetative growth, while phosphorus supports root development and flower formation. Potassium plays a vital role in water regulation and nut fill. Deficiencies in any of these macronutrients can significantly delay the onset of nut production. For example, nitrogen deficiency can stunt tree growth, delaying the time required to reach maturity and delaying the initial harvest. Similarly, inadequate phosphorus levels can hinder root development, limiting the tree’s ability to absorb other essential nutrients, further impeding reproductive processes.
-
Micronutrient Sufficiency
Micronutrients, although required in smaller quantities than macronutrients, are equally essential for pecan tree health and nut production. These include zinc, iron, manganese, copper, and boron. Deficiencies in micronutrients can manifest in various ways, such as leaf chlorosis (yellowing), stunted growth, and reduced nut set. Zinc deficiency, for instance, is a common problem in pecan orchards, leading to reduced nut size and delayed bearing. Soil testing and subsequent nutrient supplementation are crucial for addressing micronutrient deficiencies and ensuring optimal conditions for nut production. The absence of even one crucial micronutrient can act as a limiting factor, delaying the time required for the tree to begin bearing.
-
Soil pH Balance
Soil pH influences the availability of nutrients to pecan trees. Most nutrients are optimally available within a slightly acidic to neutral pH range (6.0 to 7.0). Extreme soil pH levels, whether too acidic or too alkaline, can reduce nutrient availability, even if the nutrients are present in the soil. For example, in alkaline soils, iron and zinc become less soluble, hindering their uptake by the tree. Conversely, in highly acidic soils, phosphorus can become locked up in unavailable forms. Therefore, maintaining an appropriate soil pH is crucial for optimizing nutrient availability and supporting timely nut production. Soil testing and pH adjustment, through liming or sulfur application, are essential management practices for ensuring that pecan trees can access the nutrients required for growth and reproduction.
-
Organic Matter Content
Soil organic matter improves soil structure, water retention, and nutrient availability. It also provides a slow-release source of essential nutrients, contributing to sustained tree health and nut production. Soils with low organic matter content are often less fertile and less able to support robust tree growth. Increasing soil organic matter through the incorporation of compost or cover crops can improve nutrient availability, enhance water-holding capacity, and promote beneficial soil microbial activity. These improvements contribute to increased tree vigor and earlier nut production. The presence of sufficient organic matter, therefore, enhances the soil’s ability to support the long-term nutrient needs of pecan trees, facilitating earlier and more consistent nut yields.
In conclusion, soil fertility plays a pivotal role in determining the timeframe for pecan nut production. The availability of macronutrients and micronutrients, appropriate soil pH, and adequate organic matter content all contribute to tree health, growth, and reproductive capacity. Addressing nutrient deficiencies, maintaining optimal soil pH, and enhancing organic matter levels are essential management practices for ensuring timely nut production and maximizing long-term orchard productivity. Soil testing and targeted fertilization strategies are, therefore, crucial components of successful pecan cultivation, directly impacting the timeline to first harvest.
6. Climate Conditions
Climate conditions exert a profound influence on the timeframe for pecan nut production. The suitability of a given climate determines the tree’s ability to thrive, mature, and ultimately bear nuts within a reasonable timeframe. Unfavorable climatic conditions can delay or even prevent nut production, regardless of other factors such as cultivar selection or soil fertility. Therefore, understanding the interplay between climate and pecan development is crucial for predicting and optimizing harvest schedules.
-
Growing Season Length
The length of the growing season, defined as the period between the last spring frost and the first autumn frost, directly impacts pecan nut development. Pecan trees require a sufficiently long growing season to complete all stages of nut maturation, from flowering and pollination to shell hardening and kernel filling. Regions with short growing seasons may not provide enough time for pecan nuts to fully mature, leading to premature drop or poor kernel quality. Selecting cultivars adapted to shorter growing seasons can mitigate this risk, but ultimately, the length of the growing season imposes a fundamental limitation on pecan production. A growing season shorter than approximately 200 days is generally considered unsuitable for most pecan cultivars.
-
Temperature Requirements
Pecan trees have specific temperature requirements for optimal growth and nut production. Adequate chilling hours, defined as the number of hours below a certain temperature threshold (typically 45F or 7C) during the dormant season, are essential for breaking dormancy and promoting uniform budbreak in the spring. Insufficient chilling can lead to delayed or erratic budbreak, reducing flower production and ultimately impacting nut yield. Conversely, extremely cold temperatures during the winter can damage pecan trees, particularly young trees, hindering their growth and delaying the onset of nut production. Furthermore, high temperatures during the growing season can also negatively impact nut development, particularly during the critical pollination and kernel-filling stages. Optimal temperature ranges vary depending on the specific cultivar, but consistently extreme temperatures, either hot or cold, can significantly disrupt the pecan production cycle.
-
Rainfall Patterns
Rainfall patterns, including the amount and distribution of precipitation, are crucial for pecan tree health and nut development. Adequate rainfall is essential for maintaining soil moisture and supporting tree growth. However, excessive rainfall can lead to waterlogged soils, promoting root rot and other diseases. Furthermore, drought conditions during the growing season can significantly reduce nut size and yield. A consistent and well-distributed rainfall pattern is ideal for pecan production, providing the necessary moisture without creating excessively wet or dry conditions. Irrigation can supplement rainfall in regions with limited or erratic precipitation, ensuring adequate water availability for optimal nut development. The absence of sufficient water, whether due to insufficient rainfall or inadequate irrigation, inevitably delays or diminishes nut production.
-
Humidity Levels
Humidity levels can influence the incidence of fungal diseases in pecan trees. High humidity promotes the growth and spread of fungal pathogens, such as scab, which can severely damage leaves and nuts. Disease pressure can reduce tree vigor, decrease nut yield, and delay the onset of nut production. Cultivars with resistance to common fungal diseases are often preferred in humid regions to minimize the need for fungicide applications. Maintaining adequate air circulation within the orchard, through proper tree spacing and pruning, can also help reduce humidity levels and disease pressure. The interaction between humidity and disease significantly impacts the overall health and productivity of pecan trees, directly influencing the timeframe for achieving commercially viable nut production.
In summary, climate conditions represent a fundamental constraint on pecan nut production. Growing season length, temperature requirements, rainfall patterns, and humidity levels all interact to influence tree health, growth, and the successful completion of the nut development cycle. Selecting cultivars adapted to the specific climate, implementing appropriate irrigation strategies, and managing disease pressure are essential practices for mitigating the negative impacts of unfavorable climatic conditions and optimizing the timeframe for pecan nut production. Understanding and responding to these climatic factors are crucial for successful and sustainable pecan cultivation.
7. Water Availability
Water availability is a non-negotiable requirement for pecan trees to achieve optimal growth, consistent nut production, and a predictable harvest timeline. Without adequate water, pecan trees exhibit reduced vigor, diminished nut size, and delayed maturity, impacting the timeframe for viable nut yields. The following explores critical aspects of water availability in relation to nut production.
-
Vegetative Growth and Tree Establishment
Sufficient water is critical for establishing a robust root system and supporting vigorous vegetative growth during the early years of a pecan tree’s life. Without adequate hydration, young trees struggle to develop the necessary framework for future nut production, significantly delaying the onset of bearing. For example, newly planted pecan trees require frequent watering to ensure root establishment and prevent transplant shock. Consistent water supply during this initial phase accelerates growth and brings the tree closer to its mature, nut-bearing stage. Failure to provide adequate water during tree establishment can extend the non-productive period by several years.
-
Nut Development and Kernel Fill
The period of nut development, particularly the kernel-filling stage, is highly sensitive to water stress. Adequate water is essential for transporting nutrients to the developing nuts, ensuring proper kernel size and quality. Water deficits during this stage result in smaller nuts with poorly developed kernels, diminishing their market value and reducing overall yield. Consider an orchard experiencing a prolonged drought during the kernel-filling period. Even if the trees flowered and set nuts successfully, the lack of water inhibits the nuts from reaching their full potential, resulting in a significant reduction in marketable yield. Consistent water availability is therefore crucial for maximizing nut size and quality, thereby shortening the return on investment.
-
Flowering and Pollination
Water stress can negatively impact flowering and pollination, two critical stages in the pecan nut production cycle. Adequate water is necessary for the development of healthy flower buds and the successful completion of pollination. Water deficits can reduce flower numbers, decrease pollen viability, and hinder pollen dispersal, all of which contribute to reduced nut set. An example is a spring drought coinciding with the flowering period. The lack of water can cause premature flower drop and reduced pollen viability, leading to poor pollination and a subsequent decrease in nut production for that year. This disruption not only affects the current season’s yield but can also impact future production by weakening the tree and reducing its capacity for subsequent flowering.
-
Disease Resistance and Overall Tree Health
Water availability is intrinsically linked to a pecan tree’s ability to resist disease and maintain overall health. Adequate water helps trees withstand stress and defend themselves against pathogens, particularly fungal diseases. Water-stressed trees are more susceptible to diseases like pecan scab, which can severely damage leaves and nuts, reducing yield and delaying future production. Consider a scenario where two orchards are planted with the same pecan cultivar, but one orchard receives consistent irrigation while the other relies solely on rainfall. The irrigated orchard is better able to resist disease and maintain its vigor, leading to earlier and more consistent nut production compared to the rain-fed orchard, which experiences greater disease pressure and delayed maturity.
In conclusion, water availability constitutes a primary driver of pecan nut production timelines. Consistent and adequate water supply throughout the tree’s life, particularly during establishment, nut development, and flowering, is essential for optimizing growth, yield, and kernel quality. Irrigation management plays a crucial role in ensuring that water needs are met, especially in regions with limited or erratic rainfall. The investment in irrigation systems and water management strategies directly translates into a more predictable and timely return on investment through increased nut production and enhanced tree health.
8. Pest Management
Effective pest management is inextricably linked to the timeframe of pecan nut production. Uncontrolled pest infestations can significantly delay the onset of nut bearing, reduce nut yields, and compromise the long-term health of pecan trees. The impact of pests extends beyond immediate damage, often creating conditions that prolong the period before a commercially viable harvest can be achieved. Neglecting pest control allows populations to build, inflicting cumulative damage that stunts tree growth and disrupts the reproductive cycle. For instance, a severe infestation of pecan phylloxera, a microscopic insect that feeds on developing foliage, can defoliate young trees, hindering their growth and pushing back the timeline for nut production by several years.
Common pecan pests, such as pecan weevils, shuckworms, and aphids, directly target developing nuts and foliage, impacting both current and future yields. Pecan weevils, for example, lay eggs inside developing nuts, leading to kernel damage and nut drop. Shuckworms bore into the shucks, disrupting nutrient flow to the nut and causing premature shuck split. Aphids, by feeding on sap, weaken the tree and reduce its photosynthetic capacity. Integrated pest management (IPM) strategies, incorporating monitoring, cultural practices, biological control, and targeted insecticide applications, are essential for minimizing pest damage and ensuring a timely harvest. Consider an orchard employing a proactive IPM program. Regular monitoring allows for early detection of pest infestations, enabling timely intervention with appropriate control measures. This preventative approach minimizes pest damage, promotes healthy tree growth, and ensures a more predictable timeframe for nut production compared to an orchard that reacts only after significant pest damage has occurred.
In conclusion, effective pest management is a critical component of pecan cultivation, directly influencing the timeframe for achieving commercial nut production. Uncontrolled pest infestations can delay the onset of nut bearing, reduce yields, and compromise long-term tree health. Implementing IPM strategies, including monitoring, cultural practices, biological control, and targeted insecticide applications, is essential for minimizing pest damage and ensuring a more predictable and timely harvest. Successful pecan growers understand that proactive pest management is not simply a reactive measure but an integral part of their overall production strategy, contributing significantly to the long-term profitability and sustainability of the orchard. The absence of robust pest management can extend the non-productive phase of pecan trees, significantly impacting the economic viability of pecan farming.
9. Sunlight Exposure
Sunlight exposure is a primary determinant influencing the timeframe required for pecan trees to initiate nut production. Adequate sunlight is essential for photosynthesis, the process by which trees convert light energy into chemical energy in the form of sugars. These sugars fuel tree growth, development, and ultimately, nut production. Insufficient sunlight exposure can limit photosynthetic activity, slowing growth and delaying the onset of nut bearing. The relationship between sunlight and nut production timelines is, therefore, direct and significant.
-
Photosynthetic Efficiency and Tree Vigor
Photosynthesis, driven by sunlight, generates the carbohydrates necessary for all aspects of tree growth, including root development, trunk expansion, and foliage production. Vigorous tree growth is a prerequisite for early nut production. Trees shaded by competing vegetation or planted too closely together experience reduced photosynthetic efficiency, resulting in slower growth and a delayed transition to the reproductive phase. For example, a young pecan tree planted under the canopy of a mature oak tree will struggle to obtain sufficient sunlight, leading to stunted growth and a significantly extended period before it begins to bear nuts. Conversely, a tree planted in full sunlight will exhibit more rapid growth and reach the nut-bearing stage sooner.
-
Flower Bud Differentiation and Nut Set
Sunlight exposure plays a critical role in flower bud differentiation, the process by which vegetative buds transform into flower buds. This process occurs during the late summer and early fall and requires adequate carbohydrate reserves. Insufficient sunlight during this period can reduce the number of flower buds formed, limiting the potential nut crop for the following year. Furthermore, sunlight exposure is also important for nut set, the process by which fertilized flowers develop into nuts. Shaded branches often exhibit poor nut set due to reduced photosynthetic activity and carbohydrate availability. The implications are clear: consistent and adequate sunlight exposure is essential for both flower bud formation and successful nut set, directly impacting the timeframe for predictable harvests.
-
Tree Spacing and Orchard Design
Orchard design, particularly tree spacing, directly impacts sunlight penetration throughout the orchard. Overly dense plantings result in shading, reducing photosynthetic activity in the lower branches and delaying nut production. Optimal tree spacing allows for maximum sunlight interception, promoting uniform growth and early nut bearing. Consider two pecan orchards, one planted with trees spaced at 40 feet apart and another with trees spaced at only 20 feet apart. The orchard with wider spacing will generally experience better sunlight penetration, leading to more uniform growth and earlier nut production throughout the orchard. The densely planted orchard will likely exhibit delayed nut production, particularly in the lower branches, due to shading.
-
Pruning Practices and Canopy Management
Pruning practices are essential for maintaining optimal sunlight penetration into the tree canopy. Selective pruning removes dead, diseased, or crossing branches, improving airflow and allowing sunlight to reach the interior of the tree. Proper pruning techniques enhance photosynthetic activity throughout the canopy, promoting uniform growth and nut production. Neglecting pruning can lead to dense canopies that restrict sunlight penetration, resulting in reduced nut yields and delayed maturity. For example, regular pruning to remove watersprouts and crossing branches can significantly improve sunlight penetration, leading to increased nut production in the lower canopy and a more balanced tree structure. Conversely, unpruned trees tend to become overcrowded, leading to shading and reduced nut yields.
The influence of sunlight exposure extends throughout the pecan tree’s lifecycle, from seedling establishment to mature nut production. Optimizing sunlight capture through proper tree spacing, pruning practices, and canopy management is essential for accelerating growth, promoting early nut bearing, and ensuring sustained yields. The deliberate manipulation of sunlight exposure, therefore, represents a key strategy for pecan growers aiming to maximize profitability and achieve a predictable timeframe for returns on investment. A failure to adequately address sunlight requirements will inevitably delay the onset of nut production, regardless of other cultivation efforts.
