Q.Thick rind on Arizona Pink Grapefruit
The fruit on my pink grapefruit tree has a thick rind on it, about 10mm average. Is there something I can do to the soil via extra nutrients? Provide more water? Less water? Any suggestions would be appreciated. The tree is very established. I bought this property 5 years ago and the tree was here at that time. This is the first season that it has produced more than a dozen pieces of fruit, average size is that of a baseball, not very big.
All my best,
Beth
I strongly recommend that you get a soil test. Thick rinds often indicate a lack of phosphorus intake and/or too much nitrogen intake. It's mainly the phosphorus that helps produce the blossoms and then the fruit.
