One other reason for a yellowing calla lily is due to root rot. Root rot occurs because calla lilies don’t like having their roots soaked in standing water. Having contact with too much moisture can cause the roots to rot and contract diseases.
It is completely normal to have green spathes on some varieties of young calla plants. The buds start out green or streaked with green and turn color as they open and mature. This natural occurrence is not considered among the calla flower problems, as it will fix itself in time.
A common inquiry we ran across in our research was “Why are my lilies turning brown?”.
Excess fertilizer has the potential to cause lilies to turn brown; the salt in the fertilizer builds up in the soil and dries out the lily, even when it receives water. This leads to a chemical burn on the leaves, especially at the tips.
Why are the leaves on my calla lily dying?
Fungal leaf spot can occur on calla lily, particularly if soil is splashed onto the leaves. Fungal diseases can turn the leaves brown, red (rusty color) or black in spots eventually causing the leaf to die. This can be caused by overwatering, transfer of disease from other plants or splashing of soil from the ground or pot up to the plant leaves.
Another thing we wanted the answer to was; how do you fix yellow leaves on a calla lily?
Fixing problems related to yellow leaves will involve dealing with the plant’s actual planting environment. One way to correct this condition is to transfer your calla lily to a pot with well-drained soil. Repot the rhizomes carefully and don’t over-water the plants when they’ve established their roots.
What happens when calla lilies go dormant?
When calla lilies enter the dormant period when active growth is over, the flowers will often change colour, turning green or brown, then wilt and fall over. If the plant is left dormant for at least 60 days, receiving no water, then repotted in fresh soil, it should begin regrowth with coloured flowers again.
This extra water will lead to root rot, so consistently eliminate water from the saucer after watering your calla lily. You can carefully remove the calla lily from the pot to see if the roots are healthy or rotting. You’ll be able to tell by looking at the roots. White, fibrous roots signal a healthy plant.
