Causes and treatments of yellow leaves of Buddleija

1. Too much light

Reason: The yellowing of the leaves of Buddleja salsa has a lot to do with sunlight. Buddaria prefers light, but cannot tolerate strong light. Excessive light will burn the leaves and cause yellow leaves to appear.

Solution: Move it from its original location, place it in an environment with adequate sunlight, cut off the yellow leaves, and wait for it to recover. When breeding, if it is spring and autumn, because the light is more suitable, you can let it receive light all day long, so that it can carry out photosynthesis better and grow better. After entering summer, because the light is relatively strong, appropriate shade is needed to prevent the plants from being burned by strong light.

2. Excessive watering

Reason: Because this plant likes dryness and is afraid of waterlogging. If a large amount of water accumulates in the potting soil, the problem of root rot will become more obvious, resulting in yellowing leaves.

Solution: Move the flowers to a sunny and ventilated place as soon as possible to allow the water in the pot to evaporate quickly. If the problem is serious and waterlogging and root rot occurs, the rotten roots need to be trimmed off in time, then disinfected and replanted.

3. Excessive Fertilizer

Reason: The plant Buddleja does not require much fertilizer during its growth. If too much fertilizer is applied, the roots will be burned and turn yellow.

Solution: Excessive fertilization leads to yellow leaves, so you need to remove the plant from the pot, clean the roots, and plant it in new soil for maintenance. It does not have very high requirements for fertilizer, so it does not need regular fertilization. Just apply an appropriate amount of base fertilizer to the substrate soil before planting.
