Azalea in a pot, plus small problem
I wasn't sure which topic area i should post this so i chose what made sense to me. I purchased a coral bells azalea and it's beautiful, it's in a 1gal container and i want to re-pot it to a larger one, question is how large? i want to keep it there for about a year (my future plan with it is to turn it into a bonsai, maybe) should i get a 15"H x 18-1/2"W x 18-1/2"D or a 9"H x 14-1/2"W x 14-1/2"D. The pot that my plant is in now is 7"H x &7"W x 7"D.
As for my second question, i recently found these strange spots on my azalea, interesting thing is it's only on one half of the plant.
