If the lemon does not get full sun the amount of fruit is usually diminished. Would moving it two feet make a difference in the sun it gets? Moving it should be easy enough, if the small move would make a big difference either now or in the years to come. Al

I concur. I would certainly move the Meyer now. It will just be more established the longer you wait. But 2 feet may not be enough, depending upon what kind/size plum tree you have. That plum may continue to grow and in a couple of years, you're back to square one, with the plum and lemon being too close, unless you keep the plum tree trimmed. Just be sure to dig up as large a root ball as possible, try to handle the tree by the root ball, and don't lift by the trunk, as that can damage the fine root hairs. Be sure to innoculate/dust the root ball with some mycorrhizae to help the roots get established, and top dress with good compost when you transplant. Do NOT fertilize for a couple of months, to allow the roots to get re-established. Good article in the link below about the myth behind "transplant" fertilizers.

Thanks for the advice! I'm so impressed by the generosity of this board.

I have already told hubby about his weekend plans. ;)
