The optimal timing for initiating calla lily growth from corms (often referred to as “bulbs”) is dictated by climate and cultivation method. For outdoor planting, waiting until after the last expected frost is crucial. Indoor cultivation offers greater flexibility regarding the initial planting timeframe.
Adhering to the appropriate seasonal window is paramount for successful calla lily development. Premature planting in cold soil can lead to rot, while delaying planting unnecessarily can shorten the flowering season. Aligning planting with the natural growth cycle maximizes the potential for robust blooms.
