Here we’ll delve deep into the causes of browning leaves in Calla Lilies and provide solutions to fix them so that you can rejuvenate your beloved plant.
Causes Of Brown Leaves In Calla Lilies
Calla Lily leaves turning brown can be caused by a range of factors.
Environmental stressors, such as too much sunlight or incorrect watering, cold temperatures, dry air, pest infestations or fungal diseases, and nutrient deficiencies, can all contribute to the issue.
Understanding the underlying causes can help prevent and treat brown leaves in Calla Lilies.
Environmental factors play a significant role in the health and appearance of your Calla Lilies, with many issues that can lead to brown leaves being directly related to their growing conditions.
For instance, Calla Lilies thrive in bright but indirect sunlight.
Placement in direct sunlight can cause sunburn, leading to unsightly brown patches or crisp leaf tips.
Overwatering or underwatering your plant may also contribute to the problem of browning leaves.
When Calla Lilies receive too much water, they become susceptible to root rot, negatively affecting their ability to take up nutrients and oxygen adequately.
This will eventually manifest as yellowing leaves that turn brown and die off.
Exposure To Direct Sunlight
Exposure to direct sunlight is a common cause of Calla Lily leaves turning brown.
While these beautiful plants enjoy bright, indirect light, they can suffer from sunburn when placed in areas with harsh, direct rays.
The delicate foliage of the Calla Lily plant becomes stressed and damaged, resulting in curling leaves as it tries to withstand the intense heat and radiation that comes from unfiltered sunlight.
If you suspect that your Calla Lily’s leaf browning issue stems from excessive exposure to sunlight, there’s an easy fix: simply relocate your plant to a more shaded area or protect against intense UV rays.
For instance, moving the plant near windows with filtered light can offer just enough brightness without causing harm.
