I have an improved Meyer lemon, a Miho Satsuma and a Mexican thornless lime.
I am not a fan of the lime. It has had continual problems with mealies. I spray regularly with neem.
On the satsuma and the lemon, I use a nail clipper to nip the thorns. My choice and it doesn't seem to affect the plant. I do that so am not inpaled when moving these plants.
In order to keep them in containers, every two to three years, I remove them, cut a couple of inches off the root ball, remove the loose old soil and repot with fresh soil. Their size will be compromised by keeping them in containers to begin with but it is also recommended to prune them back before new bloom growth.
Their biggest enemy in a container is overwatering.
They require minimal fertilizer. I use an organic citrus fertilizer twice a year. I use it only when they are outside of the greenhouse as it produces an incredible population of fruit flies.
I have taken to leaving them outdoors until we get a killing frost. Then I move them in temporarily. I know a few folks that have planted in ground here (zone 8a) and if the weather is ugly, they will use Christmas tree lights and wrapping for protection. Once an inground tree is older, it can be left exposed.
The only other problem might be wind blowing the container over. These will get top heavy when bearing fruit. You might take that into consideration.
Good luck, K
