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.
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.
I purchased a dwarf lemon tree in July. It had green lemons on it when I purchased it. It has been 5 months and they are still green. When will they turn yellow? The tree has started to have many clumps of blooms on it. Is there something I need to do?

In what month would it be best to plant lemon tree clippings and any instructions you can give me on the care of lemon tree.
Assuming you are referring to a young lemon tree started from a cutting, you'll want to grow it on in a pot until it's at least 12" tall; some people recommend 4' tall. This may take several years. Planting into the ground in late spring would be a good time. Here are some articles on lemon care: https://www.gardeningknowhow.com/edible/fruits/lemons/how-to-grow-a-lemon-tree.htm

I brought my lemon tree indoors for the winter. It had lots of flowers and it looks as though some of them have been fertilized. Where the base of the drying flower connects to the tiny lemons there is a sticky substance. Normal or bugs?
Interestingly enough, I'm not sure. I'll have to go out and check some fruiting plants. Until I get a chance to do that, check carefully for aphids or scale - those are usually the source of stickiness.

I have a lemon tree that blooms flowers. The flowers turn into very small green lemons but after a while they turn yellow and fall off the tree. Is there something I can do so that the lemon will continue to grow?
There can be a few things happening that can cause the fruit to drop. The most common is that the flowers were not pollinated. If your tree is located in a place where pollinators can't get to it, you can hand pollinate it with a small paint brush. Just go from flower to flower and swirl the paintbrush inside the flower.
The second most common reason for baby lemon drop is a lack of water. Lemon trees need more water when they are in fruit and it is helpful to provide more water to them when they are in fruit.
The most likely problem is that the tree has too many fruit to support. You can pinch off some of the flowers, and you can also pinch off some (app. 3 out of every 4) fruits when they are still green, to see what happens. Here are some other possibiities: https://www.gardeningknowhow.com/edible/fruits/lemons/lemon-tree-not-fruiting.htm
While giving my potted lemon tree a delightful day out on the deck before the long winter, the poor think became infested with a soil based pest. They are grey with multiple legs, capsule shaped bodies and I can only see them when I water, because they come up to the surface to escape. I want to safely kill them without harming the tree. I don't know what type of lemon tree it is. Also, according to your site, I need to repot it as well. Perhaps I can take care of both issues at once. Please help. This plant is roughly three feet high and I got it at 4 inches. Thanks in advance.
Yes, I would repot the plant with fresh soil. I would also treat the plant and soil with neem oil, which is safe to use but effective on most insect pests.
I have a couple "Kagzai Nibu" (lemons with a very thin skin) variety in flower pots. One of them has lost a few leaves (I read your articles regarding loss of leaves). It has flowers blossoming on its branches; however, I notice that once the pollination has taken place and the small fruits begin to form (a few millimeters in diameter or a little larger), they simply fall off the shrub. The other is healthy but does not flower. Hence, I am completely lost and need your help.
Plants are individuals, just as people and animals are, so although they may be the same kind, they don't all behave the same. Losing immature fruit is not all that uncommon. Here's some information on that problem: https://www.gardeningknowhow.com/edible/fruits/lemons/lemon-tree-fruit-drop.htm

One thing that suggest to me is that the pots may not be large enough. This would cause the plants to be unable to grow enough roots to support fruit. Here's more info on growing lemon in containers: https://www.gardeningknowhow.com/edible/fruits/lemons/growing-lemon-trees-containers.htm
Make sure you are watering properly. Work some bone meal into the soil, and don't use too much high-nitrogen fertilizer (first number.) Make sure the flowers are getting pollinated.
