I have been planting lemon trees from seed for a couple months, but I am noticing that some of the seeds are developing into a vine-like sapling as opposed to a more standard young tree. Is there any reason for this? Are these different types of lemons?
It appears that some other seed has made its way into the soil at some point. That does not appear to be a citrus.
However, if you crush the leaves and get that standard "citrus" smell... There is a chance that it could be infected with a viral infection.
This is not likely, as it would have spread to the other plants, but is a possibility.
In the meantime, this collection of articles will give you all of the information that you could need about lemons trees:
I planted a potted lemon tree in the ground but it needs to be moved to a sunnier spot that has room for it to grow. So far, no fruit has grown. It is getting taller but on the skinny side. I have no experience with growing citrus plants. Help!
It will be possible to do so, but this will be best done in Spring. These articles will help:
I have a full grown lemon tree planted at least 1 year ago or more. I have not had any blossoms. I water regularly it has a southern exposure. I fertilized it before planting, what else can I do?? Thank you.
There are a few possibilities, here. First, I would suspect that it needs more time. Realistically, you might see significant flower production after 2 or 3 years. This is given that all parameters are met, and the tree is old enough to flower.
Before feeding, I would do a soil test to make sure that it doesn't need, only, one or two nutrients. Most nutrients are lumped together, and having too much nitrogen in the soil, when all you need is phosphorus and potassium, will inhibit flowering.

In the past 3 weeks healthy branches have been turning white and lemons are dropping off. Leaves are turning brown. I live in Wildes Meadow southern highlands of nsw.
It could be a cottony cushion scale infestation. Here is more info as well as info on environmental concerns:
My neighbor thought they were white flies, but they do not move or fly. The tiny white sticky things on the top of the leaves on my little lemon tree (10 inches) keep re-appearing. I removed them with a tissue, but they keep coming back. I just sprayed the plant/tree with rose bush bug spray and most of them disappeared, but not all. What are they and how do I get rid of them permanently ?? Thank You.
They likely are aphids. Here is more:
I have an indoor lemon plant and there are white spots on the leaves and limbs. It can be removed with a shower and by my fingers. What is it and how is it removed?
It could be powdery mildew or a scale insect. Powdery mildew looks like talcum on the leaves. It is a fungal disease, usually from too much shade. Since yours is indoors, it may not be getting enough light.
There is a cushiony scale insect that leaves white spots. Here is info on both problems that should help:
And if so how? I will be losing 40 of them!
They look like they are a good size, and the most mature ones should go ahead and turn yellow. Size is more important when harvesting, than color. Put them on a bright counter in your kitchen, but not in direct sun.
