What to Do When Murraya paniculata Leaves Dry Up? Master the Right Methods to Restore Lush Green

Murraya paniculata is worth viewing all year round, and it looks best in early summer when new leaves unfurl. But Murraya paniculata is also a green plant that requires a lot of care. Recently, some flower lovers have run into the problem of Murraya paniculata leaves drying up, so what should be done when Murraya paniculata leaves dry up? Below is an introduction to the causes of Murraya paniculata leaves drying up and the solutions.

1. Normal metabolism, no treatment needed

If the indoor temperature is too high in winter, it disrupts the plant's dormancy period. At this time it grows new leaves normally, and as new and old leaves replace each other, the old leaves will slowly turn yellow, dry up, and fall off. This is a normal phenomenon.

2. Light causes and solutions

Murraya paniculata is a sun-loving tree species. It should be placed in a spot with plenty of sunlight and good air circulation (at least five or six hours of direct light every day) to have lush leaves, abundant flowers, and fragrance. When it blooms, it can be moved to a windowsill, filling the room with fragrance. After the flowers fade, it still needs to be placed in a spot with ample sunlight. Grown in semi-shade, it is less robust than in a sunny spot, and the flower fragrance is also weaker. If it is too shaded, the branches become thin and soft, leaves drop, leaf color becomes pale, and there are few or no flowers. When brought indoors in winter, it should also be placed in a spot with plenty of sunlight.

3. Temperature causes and solutions

Murraya paniculata likes warmth. The most suitable temperature for growth is 20~32°C. It is not cold-tolerant. In winter, when the lowest temperature drops to around 5°C, move it indoors to overwinter at a low temperature (5~10°C). Moving it in too early is not good for hardening its cold tolerance. If the room temperature is too low, it easily drops leaves and affects next year's growth. Below 0°C it may freeze to death. If the room temperature is too high, the plant cannot go into dormancy properly and may even sprout indoors. When it is moved outside, a cold wind may cause the buds to retract. When it sprouts new buds again, it affects that year's growth. If the indoor temperature is too high in winter, it consumes the plant's nutrients, which is unfavorable for next year's growth and flowering. During the growth period, avoid direct sunlight and keep it in filtered shade. Only in this way can Murraya paniculata have abundant flowers and a strong fragrance.

4. Repotting causes and solutions

When repotting in winter, or when a newly purchased Murraya paniculata is potted and problems appear, repotting is bound to damage the roots. No matter how careful you are, including the impact of the new environment on the roots, factors such as water, temperature, and soil will all affect Murraya paniculata's roots. At this time, if you rush to expose it to the sun, the leaves will definitely dry up and drop, especially in the north.

5. Waterlogging causes and solutions

Too much water can also cause root waterlogging, which leads to leaf drop. Murraya paniculata is drought-tolerant. Water it by the principle of watering when dry and stopping when wet. Do not let water accumulate in the pot. During continuous rainy weather, lay the pot on its side or place it in a rain-sheltered spot. If watered too much, it often causes root rot. If the leaves curl and lose their luster, this is a signal of root rot. Pay attention and take remedial measures as soon as possible.

First, control watering and observe the changes. If after 2~3 days there is still no improvement and it has instead become more serious, remove the plant from the pot, rinse the soil off the roots with water, let them dry, then soak them in a 1:5000 potassium permanganate solution for disinfection, then place them in a 1:2000 naphthalene acetic acid rooting hormone solution and soak for 8 hours before repotting.

During the growth period, do not water too much. It is enough to keep the soil slightly moist. In the hot summer season, do not water too much, but there must be no water accumulation in the pot (bucket). At this time, it is also necessary to frequently spray water on the branches and leaves. This not only lowers the temperature and increases humidity, but also helps make the branches and leaves glossy green.

After bringing it indoors in winter, water less. It is enough to keep the potting soil moist.

6. Improper fertilizing and solutions

Improper fertilizing can also cause leaves to wither and drop. Murraya paniculata should not be given concentrated fertilizer or raw fertilizer. Fertilize in the right amount, and understand the types of fertilizer and their nutrient content. Liquid fertilizer should not be too concentrated. It must be diluted before use, otherwise fertilizer burn is likely.

Warm tip: liquid fertilizer water should not be sprinkled on the leaf surface. During the growing season, topdressing should use quick-acting fertilizer; during the dormant period, use slow-release fertilizer; generally do not fertilize during the plum rain season and in autumn.
