We bought a house with a bearing age grapefruit tree...tag said "Flame." The fruit has VERY thick skin and tough membranes that make it almost inedible. Is there something nutritionally or care-wise that I can do to help the tree produce sweeter, juicier, less tough fruit? We're in zone 8b-9a, sandy soil to which I've added lots of compost of various kinds (cow, mushroom, worm). Any suggestions?
Is my grapefruit tree missing something?
Increasing the potassium nutrition will help to produce sweeter juicier fruit.
Hitting it with bone meal 3 times a year helps with less of a thick rind.
Alot of the it has to do with how much water or no water it gets while the fruit is growing .
Cuting back Citrus tree's will not fix anything .
Don't you love Florida REDS ? lol PINK
