Question

What is the best fertilizer to use on lavender?

Answer 1

Lavender needs very little fertilizer.
You can feed it a light fertilizer in the Spring such as a 7-7-7 balanced fertilizer.
A granular slow release fertilizer is a good choice. Scatter around the base of the plant and rake and water in.
