Q.lemon flowers are falling off or little fruits falling off
Thank you telling me how to prune my Meyer lemon tree, but the problem seems to start when fruits forming or when fruits are really tiny. I am fertilizing with high nitrogen fertilizer, keeping it watered well but not over watering. I keep it in a sunny place in the sun room. Can I take off some of the flowers so there is room for fruits to form?
You can eliminate some of the blossoms or when the tiny lemons have formed, prune some of them away.
Make sure there is no number higher then 8 in your fertilizer that you are using.
Increasing light or adding some additional time with a grow light can help.
