Aha! That's the thread I was thinking of. Hmmm, not a whole lot of information on growing citrus trees, tho. The lemon tree I have (ha, looks more like a shrub to me!) is in a pot on my back porch, where periodically it gets infested by aphids...grrrr. It also has nasty thorns on it, which makes moving it around a bit iffy. I try to snip off the tips of the thorns, but it's hard to keep up. I forgot to move it out this past summer, so it's not really happy. But I've had it for oh, about as long as I've had my greenhouse, so that would be around 7 or 8 years. Ha, gotten one lemon off it in that time. Hey, I have a brief "care and feeding" document that I found a few years ago. I'll copy it off and post it here for you. It's on a different computer, so I'll put it in my next post. Take me a couple of minutes to transfer the file.
