I would plant your evergreens now and the deciduous fruit trees when dormant. Any new deciduous fruit trees I would buy bareroot in January. Select your trees carefully noting their chilling requirement and favored pollinizers. Growing fruit trees for eventual use as firewood is not cost effective. Al

Thanks, Dave. Yes, they have been hardened off. I was thinking that they would need some acclimation to our weather, since they came from a shade house and were accustomed to warmer temperatures. I would rather plant them, but I was worried about our erratic temps as of late. Highs are running upper 50's, and lows went into low 30's, but averaging around 38-40. We're going to move up to highs in the 70's this weekend before cooling back off into the mid 60's, which is still warmer than what we've had, and getting more rain. (my yard is saturated!) Low's staying consistently around low 40's. Not sure of my soil temp, but I'll check those tomorrow in the various beds...it's still pouring out there today. I'm outside of San Diego about 2K feet up in the local mountains, so we get a bit cooler here at night, but warmer than the coastal areas in the day. I'll give it a go and see what happens. I have so many plants, seedling, and seeds waiting to come up, that it's a bit like running an experiment at this point. I'm recording what I've done with each one, so I can determine what worked (and didn't) for the next go around.

I went around September of last and they had a lot of tropical fruit then. I think it really depends on what kind of fruits you're looking for. They have most fruit all summer long but if you want sugar apple, it would be August or September on. I think caimito will have to be around winter or February. If you look at my blog you can see pictures of the fruits there. I think they just started to have LongKong around that time. I really think the best time to go is around August or September. We went to Toronto's Chinatown. The Chinatown is on 293-299 Spadina Ave. Here is a link that might be useful: Canada Fruits

This is a late comment, when air-layering bear in mind that sometimes it takes the air-layered plant over a year to form adequate roots, so the time that you start the process is really non-critical. The only exception being if you are in an area where the air-layer might freeze, or become excessively dry. But since you are in zone 10, you shouldn't have to worry about the freezing part, and if you keep the air-layer moist, (but not soaking wet), it should be successful. The only other thing to keep in mind is that some plants do not air-layer well. Plants with fleshy roots, (pawpaw for example)
