Brazilwood, also known as巴西 iron tree, is deeply loved by indoor green plant enthusiasts for its unique leaves and beautiful plant shape. During the maintenance process, many plant lovers will find that the old leaves of Brazilwood start to turn yellow, which not only affects its ornamental value but also causes concern about its health. This article will reveal the reasons why the old leaves of Brazilwood turn yellow and provide corresponding solutions.
Reasons for the Yellowing of Old Leaves of Brazilwood1. Insufficient lighting
Brazilwood is a plant that prefers semi-shade. If it is exposed to insufficient light for a long time, it can lead to yellowing of its leaves. This is because insufficient light affects the plant's photosynthesis, preventing it from growing normally.
2. Improper watering
Watering is an important part of maintaining Brazilwood. Too much or too little watering can cause the leaves to turn yellow. Excessive watering can lead to waterlogging in the soil, causing root hypoxia and affecting the plant's normal growth; insufficient watering will make the soil dry, leading to leaf dehydration.
3. Soil problems
Soil quality is crucial to the growth of Brazilwood. If the soil drainage is poor and prone to waterlogging, or if the soil is too barren, it can cause the leaves to turn yellow.
4. Improper application of fertilizer
Improper application of fertilizer is also one of the reasons for the yellowing of Brazilwood leaves. Excessive application of fertilizer can lead to high soil salinity, affecting the plant's nutrient absorption; while insufficient fertilizer application will cause slow plant growth and yellowing leaves.
5. Diseases and pests
Diseases and pests are also reasons for the yellowing of Brazilwood leaves. Common diseases and pests include red spiders and scale insects, which absorb the plant's nutrients and cause leaf yellowing.
Solutions for the Yellowing of Old Leaves of Brazilwood1. Adjust lighting
Place Brazilwood in a semi-shaded environment, avoiding direct sunlight. If lighting is insufficient, artificial light sources can be appropriately increased.
2. Control watering
Water according to the dryness and humidity of the soil, avoiding waterlogging. Generally, keeping the soil slightly moist is sufficient.
3. Improve soil
Choose well-drained soil and change the potting soil regularly to ensure soil fertility.
4. Reasonable fertilization
Apply fertilizer according to the growth stage of Brazilwood. Spring and autumn are the vigorous growth periods of Brazilwood, during which the amount of fertilizer can be appropriately increased; in summer and winter, growth is slow, and fertilization should be reduced.
5. Control diseases and pests
Regularly inspect Brazilwood and deal with diseases and pests in a timely manner. Pesticides and fungicides can be used for prevention and control.
The reasons for the yellowing of old Brazilwood leaves are diverse, but as long as the cause is identified and corresponding solutions are taken, Brazilwood can recover its vitality. I hope this article can be helpful to you and help you raise healthy and beautiful Brazilwood.
