Boo I hear you! I'm coleus challenged in my climate sigh. This year I bought some biggies and they are very happy (so far) in a big container up against the house that I can climate control.
They don't like the cold mountaintudinous nights and the dry, dry here. Charleen and Boo you probably have too hot, hot issues and Boo you're really dry, dry too. Coleus be a tad persnickety methinks
that's so annoying Charleen.. don't know for sure.. but someone said if you pinch it further than the flowers sometimes it will forget it wanted to flower.. just not sure how far back they meant
