I brought my Myer Lemon Trees into my house mid-October. (Washington, DC) They were healthy with lots of lemons. I then watered the plants and fed according to directions, Espoma Organic Citrus-Tone. Pkg stated to be used late Winter (Jan-Feb), (May/June), and (Sept/Oct). Afterward, the topsoil began to have mold on all three plants. And leaves are falling. Please tell me how to fix my trees. Thank you Betty Pace

Mold on the surface of the soil may indicate overwatering and or lack of air circulation.
The soil should dry slightly between waterings.
Also the citrus will need a good amount of sunlight for 5 to 6 hours a day.
