I have planted both the Meyer lemon tree and the lime tree. I purchased the trees in a hardware store (Orchard). The trees is planted next to a 6' block wall. The block wall provides shade all day. My question is do the trees need direct sunligh to grow better. I have a second questions, the temperatures in my area are droping to mid 30's some times, but are avering aroun 40's. Will my trees survive, what can I do to make sure my trees will survive the winder.
Meyer Lemon is a very hardy tree, and temperatures in the mid 30's should not bother it. The lime is another story. Limes are VERY tender trees, and temperatures below freezing will cause a problem. The trees will do OK in light shade, however the fruit production will be reduced.
Your block wall will provide some extra heat-- a sort of microclimate. Which side of the wall are they on (N,S,E or W)? South would be best, but they must be on another side or they would not be shaded. The west side would be second best for cold protection as the wall would retain the late afternoon heat from the sun. Like Millet said limes are very sensitive to cold, but you can wrap it with Christmas lights and cover it whenever it gets near freezing--that might get it by if the temps don't go below the upper 20s.
