I had to look up precocity to see if it meant about to die of heat stroke, which me, my dogs, and my plants have been about to do.

For others out there who might be able to help, but like me don't know what precocity means, I will at least try to get the ball rolling that far...

precocity - The state of being precocious, or far ahead of normal developmental schedules.

no one has any info? I know kufflecreek says that it has a dwarfing effect on them just wonder about precocity.

My pears and apples are running late this year because we had a very cold spring.

All I see from heat is that both the pears and the apples stop growing. Our temps are in the 90's right now and the pears and apples virtually go to sleep and wait it out.

The new baby apricots love the heat though. You can almost see the limbs get longer and hear the plants humming a happy song. Poor things. They are in for a big surprise this winter.

On a side note, macmanmatty2, you really should put your e-mail address on your Gardenweb My Page instead of as part of your "posted by" info, unless you like Spam, because these are public forums which show up in a google search. If you opt for allowing members to "Contact Me" they can send you an e-mail that way, without your e-mail address being public.

Plants stop growing when temperature is over 90F.

I think definitely yes. My apples have like one fruit first year. the only one I will
allow of course, one must grow the tree. But by 3rd year you should have a nice
crop and in 5 a large one. Be very wary of borers on your trunks, check often and spray when necessary.
This would need an answer from someone growing in say zone 6 and 7 to really
know if there is a difference.
