I have a couple of indoor lemon trees that went without water while I was away for a couple of weeks. When I got home I watered them, and after waiting a couple of days it seems almost all the leaves are dead, though the wood does not feel dead. The plants are 2-3 years old, relatively small and not bushy, and have born no fruit to date.
The tip of one branch looks good. I was wondering whether it would be a better idea to clip the healthy piece (4-5", two sets of leaves) and transplant it or if I should leave it in place to help revive the rest of the plant.
Are there any principles to guide this choice? I haven't grown many fruit trees.
