Grapefruit Tree Is Full Of Very Small, Thick Skin

Question

Last year, our grapefruit tree had beautiful, large, sweet pink grapefruit. This year we have lots of grapefruit, but they’re very small, thick skinned and not sweet at all.

Answer 1

The crop may have needed thinning. Often citrus trees produce more fruits than they can bring to maturity and it is necessary to reduce the crop. Also, be sure they are getting the proper irrigation and fertilizer. These articles should help:
