What a great find! Personally, I would separate the trunks (which look to be a decent size) into separate pots. I would completely bare root and then carefully untangle the roots and re-pot all separately. They don't look in bad shape at all. Give them some good potting medium, fertilizer and sunshine and I'll think you'll have yourself some great citrus trees.

In regards to the bushiness, both my key lime and Meyer lemon naturally grow very bushy. To get a more tree like form, requires either grating on a tall rootstock (which some nurseries do) or pruning to create a central leading branch, where all other branches come from. After a few years of letting my Meyer and Key Lime be bushy, I can now start to see how I could prune them to be a tree shape, but it will take a few more years of growth. It just depends on your preferences for tree shape. I have a nice mix of both now, some tall and some bushy. As someone who tends to over-prune and then regrets it, I would recommend letting the trees be for a while before deciding to prune for shape.

Both of my Meyer and Key Lime are also growing on their own roots aka not grafted. Whether that is good or bad depends on your location and conditions. They both can be kept small in containers and through pruning. Although my key lime is a vigorous grower and needs to be pruned more regularly.

As far as the bugs go, I have no info - I'm sure someone else will chime in.

Great looking tree(s)!! Most citrus varieties grow better when grafted onto a type of trifoliate species, however, I believe key lime trees do better on their own roots. I’ll let someone with more knowledge comment to confirm.

Thanks Alanna, I will give the separation a try. I just wasn't sure if it would be detrimental to all three or not. I will just be as delicate as possible. Looking forward to having three for the price of one.

Looks like they rooted three cuttings in pot and all took. Looks pretty healthy if it ain't broke don't fix it is my opinion :)

Thank you Kelly, that is great to hear that Key lime would do better on their on roots. I thought that I read somewhere if some citrus having root issues if not grafted, but I also think that it referred to in ground trees (recollection is somewhat cloudy) and I plan to put these in containers. So we will see how things go.

Thanks melike, I just figured that for $12.98 why not give it a try.

Separating the plants could certainly be stressful. Take your time, but don't let them dry out. A spray from the hose can help remove the media.

Not much you can do about the insecticide treatment, and I think HD treats everything. With citrus and HLB, that's actually a good thing.

Hibiscus is right about not letting the roots dry out. I would keep a bucket of warm water near by. Spray the roots with the hose and try to get off as much dirt as possible. Soak and swish the roots in the warm water to get much of the rest of the dirt off. It will make separating much easier. Make sure you have your repoting supplies set up and ready to go.

In addition to the above excellent advice:

A root hook makes it a lot easier to untangle the roots with the least amount of damage to the roots. A lot like combing hair. There are many out there but here is a an example: https://www.amazon.com/MAISHO-Wooden-Handle-Bonsai-，Gardening/dp/B078S1ST6B

To use it, insert the hook in soil and drag it down through the roots. You can use fingers while doing this to help along in tightly entangled spots.

Or if you are handy you could fashion it out of a old/cheap paint roller handle like this one I did using an angle grinder. In a pinch use a long screw driver or a chop stick. But the right angled root hook makes it a lot easier to drag.

Thanks Hibiscus, the hose is a good idea will give that a try. Alanna, I will use the warm water soak as well and I definitely will not attempt until I can go from start to finish. Thanks. Oh and PacNorWreck, I did a quick google after posting and found some of the info you are speaking of especially as it relates to bees. I don't know if it was applied to the plant or if it is a systematic thing. I hope giving it an extended hose will maybe help if it was sprayed on. Thanks for the link. Thanks tropicofcancer for that hook idea. I do have and old paint roller handle so I will try to fashion one from it. With so much input and so many great ideas which I had no clue of, I can approach this with a lot more confidence. Thank everyone so much.

As Alanna said, make sure to have your repotting supplies ready. That includes a pair of pruners to cut off any L shaped or circling roots. I find that a screwdriver does an OK job of untangling roots. I try use it as little as possible though because I want to limit root damage. Instead I try to remove as much soil as possible by dunking and spraying with a hose.

Doc - a beautiful tree.

That looks awesome Doc. Will look forward to seeing how these progress. Thanks for the photo.

Thanks for the heads up on the roots Vladimir. I will watch those as well.
