How to Organically fix yellow Citrus leaves

Do worm castings work too?

You mentioned fertilizing citrus trees with organic citrus fertilizer. What kind of fertilizer is this. Is it available in normal NPK form? If that is the case what is the value of each ie nitrogen, phosphorus and potassium? Thanks for the video.

Do you fertilize in summer? Mine had a bunch of flowers but they all fell off and I didn’t get any fruit do you know what it could be? I’m in zone 9b az

Uk is the worst place in the world to grow citrus plants if anything impossible
