Camellia leaves may turn brown due to several abiotic factors including poor drainage, drought, sunscald, mineral deficiencies or injury. Leaves may also curl, turn black and die. Providing your camellia with well-drained soil and adequate water and nutrients can prevent browning.
Correspondingly, what causes bud drop on camellias?
Hot weather during the fall or spring, which may encourage shoot growth and cause the plant to drop its flower buds. Avoid planting varieties that bloom late in the spring and plant in a shadier, cooler location. Other plant stresses due to a lack of nutrients, poor soils or drainage. Camellia bud mites.
Why are my camellias losing their leaves?
Leaf Drop. Despite their evergreen status, camellias do drop some leaves annually. Natural leaf drop occurs in spring and the leaves that yellow and die are promptly replaced by new foliage. Leaf drop most often occurs when camellias are deprived of adequate oxygen by poor soil drainage or too deep planting.
Why are the leaves on my camellia turning yellow?
Being ericaceous (acid-loving) plants, camellias can suffer from iron and manganese deficiencies if the soil or growing medium is too alkaline. Don't worry about leaves turning yellow and falling in spring or summer if this is confined to old leaves near the base and within the plant.
