I have a Meyer lemon plant near my home that gets full sun everyday from about 10:00 am to sunset. The plant is spread out like a bush (about 2 feet high) and has not bloomed for the past three years (at least). What can I do for this plant? Some people have told me I need to add another sex of lemon tree, but I'm not much of a gardener and I definitely wouldn't be able to tell the difference if that were true.
It seems that you are right on the line of where they can survive. Temperatures, on average, have been a little cooler these past few years, which would explain the lack of fruiting and growth.
You can try adding a little phosphorus and potassium to the soil, and mulching heavily in winter. Unfortunately, though, cooler years will keep growth at a minimum for your tree.
Tangerines, and sour oranges can be grown in your area with no problems, as can some sweet oranges. This article will offer more information on cold hardy citrus: https://www.gardeningknowhow.com/garden-how-to/gardening-by-zone/zone-8/zone-8-citrus-trees.htm

I ordered some Meyer lemon and a Persian lime tree from 2 different growers. The lemon and lime tree (from the east coast grower) arrived in great condition. I acclimated them per the grower instructions and re potted them. They are doing great. Then, after some weather delays the improved Meyer lemon I ordered arrived from the west coast. The plant had a long travel go but arrived only a smidge worse for the wear (parched, left on my doorstep for hours at freezing temperature). Pretty girl has blossoms though. While I was giving her a drink, I noticed that her leaves had holes and she had aphids. I thoroughly cleaned the leaves. Absolutely no directions from the grower as to acclimating and when to repot. I will follow the directions of other grower. But since she arrived with aphids it would be best if I quarantine her to another part of the house away from my healthy lemon/lime even though I washed the leaves, correct? I put her upstairs. Same south western light but just not near the other healthy plants.
This is one of the mildest pests that will attack your citrus. They are the easiest to get rid of, but there will be times that you have much harder to control insects on them. You were correct in isolating them until the infestation is gone. Continue to wash them off or follow tips below.

The lemon tree gets adequate fertilizer I think and enough water. I give 7 litres twice a week. Sorry I don't have a photo; the tree is lovely and green and it gets the flowers, but very few fruit. thank you. Diane Bremner
Being in Washington, I am assuming that these are in container, and are brought in during the winter. The most common factor with low fruiting is light, Windows filter quite a bit out, and will not allow for proper fruiting alone. A horticultural grade light of 200 watts or greater will be required for any significant fruit set.
Other factors can include fertilization, which should be done with a citrus specific fertilizer once or twice per year.

I have a Meyer Lemon tree 4ft. tall in a 25 gal pot that I move inside each winter in North Texas. When the tree blooms inside, is it necessary to pollinate the bloom for lemon production? The first year produced large fruit, but each year there is less fruit? Do you have any suggestions?I also have a Mexican lime tree 4ft tall that rarely blooms, or produces limes?Thank You Felix
Meyer lemon are self fertile meaning you can get fruit with only one tree but you still need pollination. You can do that easily yourself for the lemon and the lime.

The leaves on my potted lemon tree are showing spotting with red dots appearing on these leaves. I am looking for some help on how can I stop this
That is a severe spider mite infestation. This is very difficult to get rid of at this point.
You will have to proceed with treatment, VERY CAREFULLY, if this is a grafted tree. If this is from seed, then you don't need to worry as much. A grafted tree's top, or scion, may fail leaving you with rootstock only, after treatment. This will not be the same tree that you have purchased. If it is from seed, then the entire tree is the same, so it won't matter if it comes back from the root.

I have 10 plants of lemons. All of them produce a lot of lemons but they produce in December January, and I need them to produce in June and July, so is it possible to change its timing? I am from Pakistan kpk Peshawar
If this is indoors, you can change temperature and humidity at different times of the year to achieve this. If this is outdoors, then the plant will be subject to the climate, and genetics, and will not be able to be changed.

What can I do to redeem these poor lemons? They look awful and unappetizing .
Uh-oh. This does appear to be Citrus Brown Rot. It can be quite difficult to treat, and mainly requires preventative maintenance of the tree.
