What about the rotten roots of lavender?

I. change the soil

Reason: lavender roots are not resistant to water, so the drainage of the soil must be good. Once there is stagnant water due to poor drainage, it will cause rotting roots because the roots can not breathe.

Solution: replace it with loose, well-drained and breathable soil, so that its roots can breathe smoothly without stagnant water, which is more conducive to the growth of lavender.

Second, reduce watering

Reason: lavender is not resistant to moisture, so watering too often or too much will produce stagnant water and the roots will rot.

Solution: to follow the principle of dry and wet, usually reduce the amount of water, generally once a day in summer, other seasons can be irrigated 3-5 days, watering thoroughly, do not let water on the leaves, because it may cause disease.

3. Appropriate amount of fertilizer

Reason: many people think that plants can grow better with more fertilization, but this is not the case. Excessive fertilization will cause its roots to rot, and too many nutrients accumulate so that it can not breathe, which will lead to rotting roots.

Solution: to apply fertilizer on time, the amount of fertilizer should not be too large, if the amount of fertilizer is not careful, it is necessary to water in time, so that the excess fertilizer can be discharged as soon as possible, the possibility of causing fertilizer damage is relatively small.

Fourth, adjust the temperature

Reason: too low temperature will make lavender frostbite, coupled with stagnant water, it is easy to lead to rotting roots.

Solution: adjust the temperature properly, the lowest temperature in winter should not be lower than 10 ℃.
