My Li Jujube that’s is growing like crazy has brown dead tips to leaves. Not all of them but many. I first noticed this after a cool morning ~31-32F.
I blamed it on the weather thinking the fragile leaves got nipped but it continues----only on this tree.
We had a storm with a lot of wind and I blamed this on the storm because it occurred on the three tallest branches…
If it’s the weather it did not have an effect on the Chico. The branches that received this damage are long and upright and could have whipped in the wind stronger than shorter branches on the other tree. As a whole the tree still looks good but the browned tipped leaves are scattered through it.
