Why are my pomegranates not red? .

Question

My 6 year old tree produces lots of yellowish colored fruit. I live in Phoenix and have flood irrigation in my yard twice/month.

Answer 1

Can you include photos? This could be caused by a few reasons. There may not be enough potassium or phosphorus in the soil, or the pH could be off. Alternatively there could also be a lacking of calcium and magnesium in the soil.

It is best to have your soil sampled to pin the cause. Your local extension service can help you with this. This link will help you to fine the closest one to you: https://www.gardeningknowhow.com/extension-search
