Q.Grafted lemon tree
We have moved a grafted lemon tree recently only to find the host side has died but the grafted side is very healthy. Will this bear fruit or should we start again with a new plant?? Please advise.
You certainly could still have a fruit bearing tree.
Give the tree adequate water and fertilizer.
I would certainly give this tree a chance.
Remember that you have restarted this trees fruit bearing timeline with transplanting. It may be another 3 to 5 years for you to see fruit.
