Q.Lime Tree Losing Leaves
My lime tree is 24 inches high. I planted it one year ago when it was 8 inches high. It is outdoors in warm weather, indoors in cold (I live in Maryland). It is now in a 10-inch pot. It has flourished, but now is beginning to lose some leaves regularly. Near the bottom they are turning yellow, then dropping–slowly. Do not know if I am keeping the soil at the correct dampness/dryness. And do not know if I need to repot in a larger one. I don’t think I can put it outside yet, or ever plant in the ground. Any help would be greatly appreciated.
