I bought a lemon tree from Bunnings 2 years ago. It has grown to 2m high, and it looks very healthy. It's a great looking tree, but it has not flowered. I have used a seaweed granular fertilizer and a spray on citrus fertilizer. The lime trees planted in the same area have flowered and fruited well. What can I do to make this tree flower and fruit?
It may have too much nitrogen. Give it some high phosphorus fertilizer to counter any nitrogen overload the plant may have. All well rounded fertilizers will contain nitrogen, phosphorus and potassium. However, plants can sometimes have a bit of trouble balancing out their fertilizer. If you leave it alone, the plant will naturally use up the nitrogen (which is for healthy leaf growth) and should balance itself back out. But, if you want to speed things along, a little bone meal, which is a high phosphorus fertilizer, will move things along quicker.
I have a small lemon tree in a pot indoors (since October) with two lemons on it and lots of blooms, but the leaves look dry not healthy like they did when I had the tree outdoors. I live in Colorado and it will be the middle of May before the tree will be back ouside. I need a fertilizer for it. Could you recommend a good one? I do have fertilizer for my blueberry plants. Could I use that for my lemon tree? Thank you.

Can I grow a lemon tree in a pot in my house over the winter and put on my deck in the summer?
Yes, you can. Citrus trees do well near a sunny window in the house over winter and can be placed back outdoors for summer. This article should help with caring for a potted lemon tree: https://www.gardeningknowhow.com/edible/fruits/lemons/growing-lemon-trees-containers.htm
I have a container lemon tree that has very small gnat-like, fruit fly-like insects in the soil, not on foliage. What type of insecticide is safe to use to kill these pests? Tree is bearing fruit we plan to eat, so don't want to contaminate it. Thanks.
It sounds like you have fungus gnats. This article will help: https://www.gardeningknowhow.com/special/children/fungus-gnats.htm Neem oil will help take care of these pests but will not hurt the plants. Here is more information: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm

I have had a dwarf lemon tree for over 11 years now and, although very healthy looking, it has never produced fruit. I live in upper Midwest so plant stays outside for warmer months and I then move indoors for the winter. It gets flower blossoms but then they just drop off and no fruit. I make sure to do a deep watering every week and it is free from any insects or visable disease. Is there something I can do to get the tree to produce lemons or is this tree destined to be fruitless?
Have you fertilized? Nitrogen encourages leaves to grow, but not fruit. Too much can actually keep a plant from producing fruit. This article has information on how to fertilize your trees: https://www.gardeningknowhow.com/edible/fruits/citrus/fertilizing-citrus-trees-best-practices-for-citrus-fertilizing.htm I would also try giving it some phosphorus rich fertilizer like bone meal. If it is lacking phosphorus, it will not be able to produce healthy blossoms (which means no fruit.)

My lemon trees are about 2 feet high and losing leaves. They have mites (or whatever they're called), but I don't know how to get rid of them. I spray them with a bug killer for plants, but they come back. I want to know how to get rid of them safely, without hurting the plants. They can't afford to lose any more leaves. I'm just 13. And my mom doesn't know what to do either.
Leaf drop is a common problem in lemon citrus trees. Here is an article that you may find helpful: https://www.gardeningknowhow.com/edible/fruits/lemons/lemon-tree-leaf-drop.htm Since you mentioned a problem with mites, this could also be causing the leaf drop. I would recommend treating the tree with neem oil, which is both effective and safe to use. It also helps with a multitude of pests, should it be something other than mites.
