Blueberries usually have one crop, but you might have a bit of an extended crop if you've got different varieties and you're getting a bit more cross-pollination (you should try to always have at least two varieties for better production). I would wait until fall to transplant your blueberries into larger pots. And, you'll want to pick up a pH monitor that you can purchase at your local garden center to monitor your pH, and add additional soil sulfur. They're very reasonable. I have one, as well as a moisture meter to make sure my blueberries stay moist enough.

There are early, medium & late blueberries All three bloom & are harvested from May to July. The frost date will move the time around a little, but not much.

One year we had a stretch of warm weather in October, and several of our blueberry shrubs blossomed, and eventually there were a few green berries, that never had a chance to get fully ripe. We are in Madison, Wisconsin, and normally the blueberry shrubs bloom in May, and the fruit is ready for harvest by late June to mid-July.

Southern coastal CA can have two crops commercially on some varieties like Sharpblue and Sapphire. I'm not sure how they cause a second crop, by pruning perhaps, or if it happens naturally.

It's not unusual to have a few blossoms at odd times. A real second crop is only possible where the growing season is very long.

One other option for spring and fall crops is the "Sweetheart" variety. I recently ordered from BerriesUnlimited, but skipped this, as the price for a tiny start was 2+ times that charged for others of the same size (and the same or more as a 1 gal older plant...). But it sounds interesting and I may try it someday.

from the BerriesUnlimited URL:

"Sweetheart is a new USDA release- Super Blueberry bush- Two crops: late Spring and Fall. The bushes yield 25% more than Duke or apx 15 lbs, per bush, per year. Early ripening, superior flavor, very good firmness and excellent productivity with large fruits, 1,6 g ( the Grandfather of the plant is the Patriot berry). This plant represents a decade of research from the US Department of Agriculture Research, Education, and Economics Agricultural Research Service. This new Blueberry is a cross between Northern and Southern high bushes although hardiness zone is still questionable. Apx Zone 4-8"

Ooh, fruitnut. Didn't know that. Unfortunately, of the 8 varieties I have, none are these two. But, I do have Sunshine, which is very early, and stays evergreen here, so I'm going to watch this blueberry to see if I end up with a small little fall crop. And, my blueberries are doing very well, btw! I'll snap some pics this weekend and post. For their first year, they're really liking where they are and their conditions. Pretty pleased with myself, even after the near-fatal rat eating experience.

Thanks all, I have been looking for the cultivar that I have but to no avail. I think I have sharpblue that sound familar. But the other factor is that I brought them inside on the really cold weather days this past winter. That may have something to do with it. I know they were in full bloom in Jan and feb and I would take them out on the mild days. I am wondering how they were pollinated lol. Well anyhow I am so happy I want 4 or 5 more bushes. I will wait until fall to transplant, I bought one of those ph meters but I don't think it works everything seems to test out at 7. Thanks again Deanna

I know on Sharpblue and O'Neal have a fall crop, it is pretty small compared to Spring crop. I am in SoCal.
