A Gardeners Forum Forums General Discussion The Food Garden Forum Fruit Forum Orange Trees, No Fruit!

Hi all. New here. I have some Orange trees, including a Blood Orange in my yard. One or maybe two produced fruit this year. The others are fruitless! Do these things run in cycles? They are all mature trees that had PLENTY of fruit the past few years.

Different types of oranges bloom and mature at different times of year. It could be that when yours were blooming and ready for pollination there were some stresses that caused them to drop blooms or not be able to be pollinated some way. Or to drop immature fruit. I just never know why there has been a slowdown in fruit production in trees. Some do seem to do better some years than others. This happens with my stone fruit trees as well.

were the weather conditions different this year compared to other years? unseasonably wet or dry?

Maybe a little wetter, but not significant.

Did you escape the worst of that hurricane a while back?

Orange trees are subtropical plants.
They grow well at temperature range of 55*-100*F.
Winter dormancy temperature range of 35*-50*F.
Some mature trees will survive below 35*F, but the fruits will be damaged.

Oranges [including blood orange] are known to bear alternately.
Alternate bearings will also be induced:
1. if the fruits are left too long on the trees.
2. if fruit set is heavy in previous season.
[may need to prune to minimize alternate bearing due to heavy fruit set]

Thank you, Papito. It is nice to hear from more knowing people than I.

Yesterday I've decided to plant a mandarin tree so this topic is exactly what I was looking for :) I know that mandarin is not an orange but I think the conditions must be similar.
