My lemon tree and my ornamental orange tree both have bumpy leaves - like little lumps growing from inside. What is the cause of this as I have sprayed with oleum about 4 weeks ago but it does not seem to have helped yet. Thank you Kind regards Jenny
This sounds like what is called Citrus Canker. A very bad bacterial infection. This article will help you to identify the problem, and offer ways to solve the issue: https://www.gardeningknowhow.com/edible/fruits/lemons/common-lemon-tree-diseases.htm
My lemon tree has lost most of it's leaves. It's about 2 - 3 years old. Never has bloomed or ha lemons. It's inside in south window.
If this is from seed, then it can take upwards of about 6 years, granted that it comes from a type of lemon that is not open pollinated with wild citrus. In this case, you may never get a viable fruit from the tree. If it is grafted, then you will have to be patient. There are a few things that you will have to do in order for a citrus to remain healthy in container. You will want to add dolomitic lime every few month, along with wettable sulfur. Also give it a citrus fertilizer once per year.
The leaves will naturally fall off indoors, as there is usually not near enough light to keep them growing. There is only enough to keep them alive until the next spring. You can keep it growing by getting a horticultural grade light.

What trees can I grow in containers? Custard apple? Lemon tree? Paw paws? Orange? I've got a very young lemon tree which keeps getting some white stuff stuck on the bottom sides of the leaves and the little black ants come and eat (?) the stuff.
The white stuff is probably honeydew, a sticky substance left by aphids, scale bugs, and other small insects that feed on plants. Ants enjoy eating honeydew:

Some lemon trees and some orage trees can be grown in containers. Meyer lemon is particularly well suited:

Custard apple is a relatively small tree, and some gardeners have said they've been successful growing it in pots. Here is more information on its growth needs:

Paw paws produce a deep tap root (plunging root), so they probably wouldn't adapt well to growing in a container.
I am sad that my lemon tree that was doing so well sudden in 2weeks shed all its leaves, is that the end of my tree? can I do anything to revive it
This really depends on if it is in container, or if it is planted. They will have a little bit different of care.
If this is indoors, and you are not in a native area of citrus then this can be due to just simply being indoors. They usually cannot get enough light , no matter how bright the window, and will lose its leaves because of this.
Can you include more information? I will be more than glad to help.
I have a potted lemon tree that is relatively small however last fall got 8 delicious lemons. I bring it in during the cool to cold winter weather in s.w.Oregon. my question is I want to do what's best for it how to I take care of it inside during these cold days and nights?
These will actually need quite a bit of light indoors to be happy. I would recommend at least 100 to 200 watts per tree to satisfy its light requirements.
Another thing to note with indoor citrus in container, is that they will need regular fertilization. Once a year, you should put a citrus fertilizer, along with some dolomitic lime, and iron sulphate to keep the soil conditioned.

good morning i have a lemon tree in a pot, currently inside the house recently i noticed tens of small bugs in the soil and also flying around the tree i do not see and damage to the leaves the bugs do not go to the other plans in the room, just stay with the lemon tree i attached a picture of one of the bugs any suggestion on how to get rid of them thank you Ari
There are actually a couple of different insects that I see. If they seem to be doing any harm to the tree then I would recommend spraying with neem oil. After, you can drop a few drops of rosemary oil in the water the next time that you water them. This will help.
What nematoides should I use to ward off and control bugs?
I have many citrus i container, as well. Mind you, this is no easy task. They do require much care when grown in container. Instead of using nematodes in container, I would recommend having a few natural chemicals on hand. Neem oil, rosemary oil, garlic extract, and chrysanthemum extract are very effective insecticides.
You should keep dolomitic lime and iron sulfate handy. You will want to apply this twice a year to keep the soil conditioned, along with some citrus fertilizer at the same time you apply these. This will save you SOOOOO many problems in the future.
