Q.lime tree
I have a lime tree (in northern Florida) that produced year round. Three years ago it split and we lost half the tree. Last year we lost the other half. The tree has resprouted from the stump. It is 5 feet from a lake and gets all the water it needs. It now has multiple branches and the branches are dividing and producing off-shoots. How long before the tree starts reproducing fruit? And should I prune back any of the main branches so they become stouter?
The new growth may be growing from the the grafted root stock.
This will be some sort of citrus tree but may not be the same as the original plant.
It can take 4 to 10 years for a new Lime Tree to produce fruit.
Here is a link about pruning.
