Pachira aquatica, with its unique tree shape and auspicious meaning, is loved by many families and offices. In the cold winter, many flower enthusiasts may notice that the leaves of Pachira aquatica start to turn brown. This not only affects the ornamental effect but may also threaten the health of the plant. This article will analyze the reasons for the browning of Pachira aquatica leaves in low temperatures and provide effective maintenance methods.
Reasons for the browning of Pachira aquatica leaves in low temperatures1. Low temperature injury: With sudden drops in temperature during winter, Pachira aquatica has poor tolerance to low temperatures and is easily affected by cold damage, causing the leaves to turn brown.
2. Poor ventilation: Indoor poor ventilation leads to poor plant respiration and hindered metabolism, causing brown spots on the leaves.
3. Improper watering: In winter, water evaporates slowly, and excessive watering can easily cause root hypoxia, leading to brown leaves.
4. Insufficient light: In winter, the day is short, and if the plant is kept in a dark place for a long time, the leaves will turn brown due to lack of light.
Maintenance methods for the browning of Pachira aquatica leaves in low temperatures1. Increase room temperature: Try to place Pachira aquatica in a warm environment, maintain the room temperature above 15℃, and avoid low temperature injury.
2. Strengthen ventilation: Ventilate properly every day to keep the indoor air circulating and prevent leaf browning due to poor ventilation.
3. Control watering: Watering in winter should be moderate, keeping the soil slightly moist, and avoid excessive watering that causes root hypoxia.
4. Increase lighting: Place Pachira aquatica in a place with abundant sunlight, and ensure it receives at least 4 hours of scattered light per day to promote leaf growth.
5. Adjust fertilization: During the low temperature season, it is appropriate to reduce the amount of fertilizer to avoid excessive fertilizer causing leaf browning.
Browning of Pachira aquatica leaves in low temperatures is a common maintenance issue in winter. By using the above methods, it can be effectively prevented and resolved. It is worth noting that during the maintenance process, attention should be paid to the plant's growth condition and timely adjustments to maintenance measures to ensure the healthy growth of Pachira aquatica.
