Lemon tree

Question

I have a lemon tree and it has not fruited in the 3 years since I planted it. The lemons always drop off when they are about 2-5 mm big. Can you explain to me why this could be, please? Thank you.

Answer 1

There are a few reasons this can happen. The most common is that it is getting uneven watering. Citrus trees will drop their fruit first if they do not get enough water, even for a short period and they need more water when they are in fruit.

Pollination issues may also be the cause. If the flower is under pollinated, the tree may abort the fruit. A small paintbrush swirled in some of the flowers can help improve the pollination.
