Is it too late to start kentucky wonder pole beans and english snow peas?

It's April 19th in zone 6b/7a (Tulsa, Oklahoma).  If I start them should I plant against the west fence so they are shaded from afternoon sun?  I can use fence and nails/string as trellis.  I heard they don't like the heat and well it gets hot here at times even in spring..  like it was 92F around april 1st.. I know cray cray.

I'm not sure about your climate but around here, pole beans are "heat of the summer" crops and peas are spring or fall ones.  So I'm sure your snow peas would like some protection if they'll even grow at all.  I'm thinking the beans will be fine but I'm not sure about Oklahoma...

You are totally right! Give the pea protection from the afternoon sun and you should be fine. They definitely need protection from that heat!

Kentucky Wonders grow and produce all season long for me here in 7b.  They don't seem to mind the heat and humidity although they are planted in less than full sun so maybe that helps.  Snow peas hate me, so maybe I'm not the best to give advice, but there seems to be a very small window for planting where I can get a little harvest before they shrivel up and die in the heat.  I can't seem to find that window, though!
