What to Do When Bougainvillea Leaves Rot
Main Content Introduction: This article provides an introduction to dealing with rotting leaves on bougainvillea plants. Let's delve into the details.
What to Do When Bougainvillea Leaves Rot
When bougainvillea leaves rot, you need to prune the affected leaves and then place the plant in a bright area without direct sunlight for care. Ensure good ventilation and slightly drier potting soil, allowing the roots to recover first, and new leaves will soon grow. Additionally, we should water and loosen the soil for the bougainvillea according to the dryness or wetness of the soil, following the principle of watering only when dry and watering thoroughly when watering, to help the leaves absorb air and nutrients and alleviate the rotting leaf condition.
Causes of Rotting Bougainvillea Leaves
Signs of Rotting Leaves: Bougainvillea leaves first turn yellow, then gradually dry and rot, and finally fall off. The general reasons for this condition include:
1. Overwatering: Too much watering prevents the bougainvillea roots from absorbing water and nutrients normally, causing the leaves to always be in a state of dehydration, leading to poor growth and eventual yellowing and rotting leaves, even the death of the entire plant.
2. Improper Fertilization: Bougainvillea loves fertilizer, and a lack of it can lead to poor growth. However, fertilizing bougainvillea must be done with light and frequent applications. Too much fertilizer at once or even spreading fertilizer on the leaves can easily burn the leaves and cause them to rot.
3. Poor Potting Soil Drainage: Long-term failure to change the soil can lead to soil compaction, which not only affects the growth of the bougainvillea roots but also affects the leaves' absorption of water and nutrients, causing the leaves to lack nutrients and rot.
4. Diseases and Pests: Sometimes diseases and pests can cause rotting leaves. Common issues include leaf spot, brown spot, and red spider mites, all of which can lead to leaf rot and abnormal shedding.
Methods to Treat Rotting Bougainvillea Leaves
1. Watering: During the growing season of bougainvillea, water once a day to ensure the growth of branches and leaves. Control the water appropriately 3-4 times according to the variety, to the point where the branches and leaves slightly wilt. Then spray water on the leaves 1-2 times a day for 2-3 days, followed by thorough watering. Repeatedly controlling water or watering every other day can promote leaf greening.
2. Soil Moisture: Water and loosen the soil for the bougainvillea according to the dryness or wetness of the soil, following the principle of watering only when dry and watering thoroughly when watering, to help the leaves absorb air and nutrients and alleviate the rotting leaf condition.
3. Pruning: Prune the rotting leaves of the bougainvillea and place it in a bright area without direct sunlight for care. Ensure good ventilation, slightly drier potting soil, allowing the roots to recover first, and new leaves will soon grow.
4. Spray Medication: Leaf spot and brown spot diseases appear as spots on the leaves, which gradually expand and cause leaf shedding. Remove the affected leaves promptly and treat with fungicides. Red spider mites create cobwebs on the bougainvillea plant and cause light green spots on the leaves, which can be treated with miticides.
Preventing Rotting Bougainvillea Leaves
1. When caring for bougainvillea, be sure to protect it from frost. Long exposure to temperatures below 5°C can lead to frostbite or death. In home care, place the bougainvillea in a location free from cold winds and with sufficient light to prevent the leaves from losing their luster and rotting.
2. Bougainvillea loves fertilizer, but fertilization should be light and frequent. Too much fertilizer at once or too short intervals between applications can easily burn the roots, causing the leaves to turn yellow and fall from the bottom.
3. After a large number of leaves have rotted and fallen, reduce watering and increase ventilation to prepare for new leaf growth.
