Hello there. Just recently moved and am in zone 8b. Property has some dwarf fruittrees and some are in a green house. Avocado is drying ( found out I’m not watering enough) and the jujube is turning yellow. I’m finding it may need some fertilizer. I’ve never handled trees before and am still a novice gardener. Any advice is helpful. There are lemon, lime, barrette pears, red delicious apples, grapefruit, oranges to name a few. I truly have no knowledge of pruning and fertilizer care. I did purchase an orchard book that is packaged somewhere I cannot find of course!
Any recommendations for books or sites that simplify this?
