The Q&A Archives: Buds Dropping From Orange Tree.

Question: I have an orange tree that I keep inside in the winter and put it out in the summer. Since I bought the tree 2 years ago it has not produced any oranges. It had oranges on it when I got it. The tree buds with white flowers and gets little tiny green oranges about the size of an eraser and then drops them off. Can you give me any ideas on how to keep the buds going to become mature oranges?

I have the tree in my sunroom getting alot of sunlight.
thanks Daryl

Answer: Without more detail on how the tree is cared for it's hard to say, but here's some info that might help. Citrus is a heavy feeder and needs regular fertilizer applications. It's recommended to apply the total annual amount of nitrogen required in 3 applications: in Jan/Feb; Apr/May; and Aug-Sept. Requirements vary according to the age of the tree. Citrus fruit drop is actually a natural thinning process. Citrus trees thrive on consistent moisture. That may have been a factor in the fruit drop if the tree was stressed. Apply enough water slowly and deeply to thoroughly soak the root mass. Don't sprinkle lightly, which allows salts to accumulate and burn the roots. How often to water depends on your soil characteristics, rainfall and weather, but a rule of thumb is about once every 3-4 weeks in winter and once every 10-14 days in summer. Use a soil probe to help determine how often to apply water (such as a pointed stick or metal rod) and poke it into the soil. It will move easily through moist soil and stop at dry soil. Hope this information helps!
