You should be fine, because you are in a colder zone like me and it doesn't get really hot for long periods. I know in the warmer zones the brugs tend not to do well for them in the extreme heat. I think the only thing yo would need to really worry about temp wise is something like a sang, they do not like the heat at all and you have to find them a cool spot. I guess I'll find out if I can keep them happy this summer.

Shawn you are sure right about the Sangs. The 3 seedlings that I am keeping with the others OUTside, do not look to happy. I guess I HAVE to try to make them happy and find em a cooler place. Like the fridge maybe? lol Cause when I get hot I would love to stick my head in there.

Darn hotflashes!

Barb I have learned that none of my brugs liked the hot afternoon sun from Texas.

Lucy once you put them in the ground this year you will see a big difference in being able to take the heat. Well as far as reaching tree size at least and as much as you water you will have blooms faster too I'm sure.

Kristy I think so too. All I know is that I will have alot of cuttings to offer lol. I hope I am doing the right thing. Of course there are a few brugs that I will never dare to loose completly. So those I will even find a place IN the house next winter. I learned a lot since I started. Made way to many mistakes and it continues now with the seedlings lol. All 42 of them!

Thank you everybody! I noticed I think some dont like the gh heat. I am hoping once they get outside they will happy campers...Shade will not be a problem here. Lots of trees :)

They sell shade cloth at Home Depot pretty cheap for a small roll. I can going to put some on the inside of the roof on one side to shade some of the plants that need it.
