Most of the agricultural damage is caused by the melon and Oriental fruit flies.

Uneven watering can cause your Lemons to fall off the tree (as well as flowers). Trees need regular watering. They don't take well to drought and low humidity. One may also ask, why are my baby lemons turning yellow and falling off? Baby lemons turning yellow and dropping. This is normal and is known as post bloom fruit drop. I too have a little Meyer Lemon tree, a I am just amazed at it, It's just a little thing, and I've had it going on 3 years now.

It has one huge lemon that seems like it must be a year old and almost ripe, then another about golf ball size and I see a baby about pea size on there now.

It never had noticeable dropping of baby lemons. Dec 10, 1 Why Are Baby Meyer Lemons Dying? 2 Why Do the Fruits Fall Off the Citrus Trees? 3 Lemon Tree Insects & Parasites; 4 Black Pests on Citrus Leaves.

Jul 08, Re: Lemon has baby lemons turning yellow and falling off. Actually if your plant was grown from seed it is still young since saw cuts trees trees from seed take around 5 years to mature before they bear fruit. Meyers are pretty prolific and will have up to three cycles in a year. May 02, As for your lemons falling off, only a small percentage of the flowers will set fruit, and even after the initial fruit set, the tree will drop the fruit that it cannot support (often called the June drop).

It'd get a lot of scale and all around - not well in the house.

They turn into nice yellow pea sized lemons, then start turning brown/black, shriveling and dropping off. Not one single lemon yet. I used standard potting soil, and it gets 5 minutes of water every 3 days on a 1gph flag emitter. I've given it a couple feeding since purchasing of miracle-gro all-purpose shake 'n feed.

Good night all.

Apr 26, if the tree is not getting enough potash from your treegrinding.bar tree may be still in its juvenile stage to produce fruit at all. 26 Apr, Sid. Might also be a humidity issue - you could try standing the container on a tray of regularly damped down gravel so that the atmosphere around the plant is humidified. Nov 15, Assess the level of water provided to the citrus tree. Citrus trees that are not watered adequately have a tendency to drop their fruit prematurely.

The next season, be sure to mulch adequately around the tree to improve water retention and keep an eye on its need for more water. Equally, over-watering can force fruit dropping%(42).
