Grapefruit trees

by Gen31889653
Last year I got many grapefruit twice the size of softballs. This year they are only the size of baseballs. I have not changed my watering. What causes this?

    It could be anything. If you didn't change anything in its care, it could have been the weather or anything.

    If they are outside I would say it could be caused by whether or not they got more rain besides the water you're giving them? My family used to own a blueberry patch and even though we were watering them the fruit was always MUCH bigger if they got a lot of rain besides. Hope that helps!

      It could have been the fact that we have had no rain for 104 days in Az that might have something to do with it. Drip system water does not have the nitrogen in it that rainfall has. Thanks for the reply.

    Why is my grapefruit tree producing smaller fruit?

    Yes, Nancy is right. Our grass, plants and trees have done crazy things this year. Here in the midwest, as in most places, flowers that always bloom are not blooming, trees that never had fruit are all at once bearing much fruit, etc...Could be the rain, humidity, chemical spraying, heat, cold. ??

    Could be the bee pollination. Spray pesticide, killing the bees?

    That's the way with citrus. One year plenty, next light. This year will probably be plentiful again. And think about planting something close by that will attract more bees. That always helps. Good luck.

    Perhaps there are too many for the tree to support. See the link.
