I live in Richwood (south coastal), Texas. Because of the crazy fluctuating weather this winter, my lemon tree has baseball size ripe fruit, golf ball size green lemons, and blossoms. Is this going to hurt my tree's future performance? What should I do? This tree is a well established lemon "bush". We thought it froze about 7 years ago and chopped it down (it was about 4 years old at that time). It grew back strong and now is a tree with no trunk...if that makes any difference. Teresa P
Lemons are very cold sensitive, so whether you are able to maintain this crop of lemons will be up to Mother Nature.
Here are some links to help you.
In reference to the 'the tree growing back'.
I do think that you actually have a tree that grew back from the grafted root stock of the original tree that you removed.
The lemons that are now being produced are not likely the same fruit as you originally had on the tree.
Here is a link that explains grafting.
