Guava Plant Dropping Leaves

Evelyn Guzman added on October 11, 2017 | Answered

Hi, I have a small guava plant indoors in a large pot sitting by an open window in NYC. The weather has been very warm for this part of the year so I keep the window open. She did well all summer long but now I've noticed that she dropped most of her leaves. Do these plants go dormant and maybe this is why she's losing her leaves? Awaiting your reply. Thanks.

Thank you for sending us your gardening question. If your guava receives adequate light, and experiences leaf drop, improper watering is probably the culprit. A lack of water can cause the tree to dry out and lose leaves, while excessive watering can cause the roots to rot, so that they lose the ability to take water and nutrients up to the leaves. If you modify watering to provide even moisture, often the tree will recover, albeit slowly. A moisture meter is useful to be certain that watering is necessary, and can help you develop an appropriate watering schedule. Should your guava lose all its leaves, don't despair. You can prune it back lightly to help push new growth; then, with improved growing conditions (adequate light, correct watering) it should recover. Remember also to feed regularly with a good citrus fertilizer (3:1:1 ratio or similar).
