Re Potted Trees:

If one lives in a freezing winter area, it might be better to have a tiny greenhouse.

I seem to remember Greeneyes having an indoor lemon tree. I raised a Mexican papaya from seed and the tree grew so big, above the slider, that I had to donate it to the local botanic garden. It went outside during the late spring until fall and even flowered.
