Determining the optimal time for asparagus fern trimming involves considering plant maturity and the growing season’s progression. Typically, this task occurs after the harvest period concludes and the fern begins to yellow or brown.
Proper timing of this action contributes to the plant’s long-term health and productivity. Allowing the fronds to remain until they naturally decline facilitates nutrient translocation to the crown, strengthening it for the following year’s growth. Premature removal can weaken the plant and reduce subsequent yields.
