I've been debating doing a round of snap peas and snow peas for fall harvest. Will they do okay if we're in the 80-90's and will get cold in a month?
I haven't had experience with summers that consistently go over 80! It's a very good question.
I would try succession planting, say every two or three weeks, to discover the best date. If the first crop or two suffer badly from heat, pull them and put the 3rd and 4th crop right where the first two failed. Or interplant them and let the new ones choke out the old (but then the old ones will die and look nasty while the new ones are producing).
Actually, Dave's garden calendar says you're a little late for your location, based on first frost date:
Highlands Ranch, Colorado --> Kassler, CO
Fall Crops:
"Sow peas directly around July 16."
The latest recommended dates shown for direct-sowing any kind of pea is July 31.
But he also says:
"... remember that the numbers in this fall planting guide are only a starting point for you! "
Your microclimate and early peas may still give you some harvest.
I'm not positive that calendar takes average summer high temperatures into account.
Sorry!
