I have a dwarf lemon tree and would like to know if pine needles make a good fertilizer.
Pine needles are good for mulch for citrus trees. They also do a good job of keeping weeds down. Whenever you are using a natural mulch, make sure that you are having your soil tested regularly to keep an eye on nitrogen levels as decomposing natural mulches and deplete nitrogen from the soil.

I live in Las Vegas. I have a dwarf lemon tree that was planted before winter cold. Don't know the type. About two months ago, the leaves started falling (about half of the tree). They were green, then they stopped falling off. Three weeks ago I got a profuse amount of blossoms, which have been blooming. The leaves have started falling off again and a little bit of curling has occurred. The leaves are not yellow. We did put fertilizer spikes in (2) about six weeks ago. I do have new leaf growth but not much. Is my tree ok?
