ajpa(z6 se PA)January 23, 2009

Is there somewhere I can look this up?

I want to order bare-root bushes and have to tell the company when I want them to arrive...

Here are some averages.

This is from naturalgardening.com - It doesn't exactly give Chester County info, but you can get a good estimate.

Pittsburgh April 20 October 23

Williamsport May 3 October 13

For Delaware County, I am going by 4/14 and 10/14. But, these are averages. You still need to be careful with frost tender plants. Cloches, cold frames, row covers, etc. can help protect from light frosts.

Thanks! That helps!
I thought the extension office would have a link or something on it with the dates (but nooo, as my 12yo would say).
