leaves left. What
can I do to save the plant?
If you can attach a photo or at least give the name of the plant, we may be able to help. Have you had it a long time? Is it a houseplant? In general, many problems go back to watering, usually over-watering. Have you looked for bugs and caterpillars? Did the leaves turn brown or have dark spots before they fell off? What type of soil is it in?
