I'm a beginner gardener living in the UAE (very discouraging climate)
we have a trio of 10+ year old lemon trees who have never fruited in our yard (they don't get much care) I want to change that. Attached is a picture of one of the trees, they're thorny and scraggly. I fed them today with an all purpose plant food 14-10-27.
it's really hard to find advice specific to my climate. so any help/ recommendations are welcome ovo/
