I remember, not too long ago actually, we were living in an apartment and all I had was a tiny little balcony to grow my herbs. I had them in pots and they did pretty good. I learned that I had to let the soil dry out between waterings. They were in partial sun too, which worked out well... I think full sun in a potted plant is sometimes too much with our heat! But that was in Houston where they would grow year around without much threat of freezing temps.
You have a greenhouse? That's wonderful. I am waiting for the day! I threated my dh that I would make my own
that drives him crazy because he is a perfectionist and the thought of what I would conjure up as a greenhouse makes him shudder!!
