My lovely meyer lemon was inadvertantly left in a sunroom where the temperature was over 100 degrees (we did not expect the hot spell). We have moved it outside, the leaves are brown, but are not dropping. Some stems are still green, what should we do to revive it??
Put it in a sheltered location, water very sparingly, and cross your fingers. Citrus are good at bouncing back, but they need time to do so. Only water when the soil is dry. This may take a very long time since it likely will not use much if the leaves are dying, so keep a close watch, and let it regain its strength.
For what it is worth, I have a Meyer lemon that was shipped in February, sat in the shipping box for entirely too long, and dropped almost all of its leaves after I transplanted it. I just pretended that nothing had happened and continued to water and fertilize it, although I did cut back on both due to the loss of leaves. It is now spring and the plant is showing extensive new growth. In particular, it is growing new leaves like crazy as well as new blooms. Why it is trying to bloom is beyond me. I would have expected it to sprout leaves prior to blooms, but who am I to argue. After this experience, I would not give up on a Meyer lemon until it was as dead as a doornail. These plants are very robust in my experience.
