Meyer lemon tree

Question

I live in zone 5, and I purchased a Meyer lemon tree two years ago (I believe it was less than 1 year old when I purchased it). I have it potted, and during the summer it goes outside to a full sun location. It gets approximately 10-12 hours of sun per day.

I noticed this year it started to produce fruit. I was so happy to see it. Low and behold, a week or two later, the tiny little lemons turned yellow, than brown and fell off of the tree. Why did this happen, and how do I get it to produce fruit? I was at the store where I purchased it from, and they had more of the same trees from the same grower. They were all less than 1 year old, and I noticed one tree had two good sized lemons on it.

What am I doing wrong?

Answer 1

Most citrus trees will shed fruit if they do not have the nutrients and/or water to support the fruit. I would have the soil tested. Also, the fruit may not be developing due to a lack of phosphorus or poor pollination. This article should help: https://www.gardeningknowhow.com/edible/fruits/lemons/lemon-tree-fruit-drop.htm
