How to deal with the yellow leaves of Calla lilies
There are many reasons for the yellowing of Calla lily leaves, such as excessive or insufficient watering, improper fertilization, and unsuitable maintenance environments, all of which can lead to yellow leaves. Therefore, when watering Calla lilies, water when the soil is dry and continue until thoroughly moistened, and place them in a ventilated area to maintain fresh and circulating air. Also, fertilize appropriately, applying a small amount of liquid fertilizer topped with a layer of granular nutritional fertilizer.
During the cultivation of Calla lilies, yellowing of leaves is a common issue. We must identify the cause and address it accordingly, or it may harm the entire plant. Next, let's talk about the reasons for the yellowing of Calla lily leaves and how to deal with them.
What causes the yellowing of Calla lily leaves
1. Improper watering
Too much or too little watering can affect the plant's root nutrient absorption, leading to yellow leaves.
2. Unsuitable temperature
The optimal growth temperature for Calla lilies is between 15-25°C. Above 25°C or below 5°C, the plant enters dormancy, and yellow leaves may appear.
3. Inadequate lighting
Calla lilies need to receive more than 3 hours of sunlight a day. Insufficient lighting can cause yellow leaves.
4. Fertilization issues
Too little fertilization can lead to a lack of nutrients, while too much fertilization can cause root burn, resulting in yellow leaves.
5. Environmental pollution
Plants prefer clean air. Long-term exposure to smoke, oil fumes, or other abnormal air can cause yellow leaves.
Remedies and treatment for yellow leaves of Calla lilies
Remedial measures1. Excessive or insufficient watering
Calla lilies prefer a humid environment, so water when the soil is dry and continue until thoroughly moistened, but do not overwater.
2. Low temperature
Calla lilies are sensitive to air humidity, so it's necessary to water and spray them frequently to keep the surrounding environment moist, while also placing the pot in a well-ventilated area to maintain fresh and circulating air.
3. Over-fertilization
Excessive fertilization can damage the plant's roots and cause yellow leaves. Therefore, fertilize Calla lilies appropriately, applying a small amount of liquid fertilizer topped with a layer of granular nutritional fertilizer.
Daily maintenanceWater regularly and keep the potting soil moist, avoiding letting it dry out before watering. Also, maintain air humidity and control watering in winter. During the growth period of Calla lilies, it's best to apply fertilizer every ten days, with a preference for liquid fertilizers rich in phosphorus.
