Causes and treatments for yellowing leaves of lavender

1. Insufficient light

Reason: Lavender is a full-sun plant that loves light. It can receive full-day sunlight in all seasons except summer. Receiving enough light is beneficial to its growth. If the maintenance environment does not have enough light, it will grow slowly and the branches and leaves will turn yellow.

Measures: It needs to be moved to a place with sufficient light and longer sunshine hours, preferably one that can receive sunlight all day. Just be careful to provide shade when the sun is too strong in summer, otherwise the leaves will burn yellow.

2. Excessive water

Reason: Featherleaf lavender does not need much water to grow. It prefers a relatively dry growing environment, so the soil should not be too moist. If there is too much water in the soil, water accumulation will easily form, preventing it from growing normally. In addition, if water is accidentally spilled on the plant when watering, the leaves will be burned after being exposed to the sun.

Measures: If there is no accumulation of water, you can move it to a sunny and ventilated place, loosen the soil, speed up the evaporation of water, and make the soil dry. If there is water accumulation in the potting soil, you need to remove the pot and check whether the roots are rotten. Cut them off and replant them.

3. Environmental changes

Reason: If you suddenly change its breeding environment, its growth will slow down because it cannot adapt, and its branches and leaves will turn yellow after a while.

Measures: Don’t worry about this situation, just wait for it to adapt to the new environment. It will take about 3-5 days for the plants to adapt.

4. Fertilizer problem

Reason: If the fertilizer concentration is too high, it may burn the roots. This will hinder the absorption and transportation of nutrients, and the outside of the plant will show signs of yellowing branches and leaves.

Measures: The fertilizer in the soil needs to be diluted by watering as soon as possible. If necessary, the plant needs to be removed from the pot and the damaged roots cut off, then the soil needs to be changed and replanted. In subsequent maintenance, when applying fertilizer, make sure the concentration of fertilizer is only 1%. Also note that the proportion of nitrogen fertilizer in the fertilizer should not be too high.
