If you think your Lavender is turning yellow because of over-fertilization, flush the soil with water to remove excess from the roots.

To prevent Chlorosis, loosen the soil around your lavender plants growth to make them airier with less touch of nitrogen.


However, to create a pot that is spacious, try to amend the soil with an ratio 50:50 of loam soil and sand soil before cultivation.
