Very Common

Excessive Nitrogen Fertilization

High levels of nitrogen can stimulate rapid, succulent vegetative growth that lacks structural strength, resulting in weak, floppy stalks in Calla Lilies.

Common

Overwatering and Poor Drainage

While Calla Lilies love moisture, saturated soil prevents root respiration, leading to weak root systems that cannot support the weight of the heavy 'Captain Odeon' blooms.

2 Repot the plant in a well-draining potting mix amended with perlite to improve aeration and prevent future root suffocation.

Temperature Fluctuations

Rapid drops in temperature or drafts can stress the plant, causing it to prioritize quick stem elongation as a survival response to environmental instability.

Common

1 Stabilize the environment by moving the plant away from cold drafts, windows, or air conditioning vents to prevent further temperature-induced stress.

2 Increase supplemental lighting to provide a consistent energy source, which helps the plant maintain sturdy growth rather than stretching for light.
