Mine are in the ground for about 4 1/2 to 5 months.

Depends on where you are. Here I plant in November for harvest in late April May. By June they are gone. In more northern climates, planted in March, They should be be finished late July.

Here in the PNW I plant peas about March 1 and pull the vines in early July. They are replaced by cabbage and broccoli. - Dick

I'm in Oklahoma. Plant them March 15, pull them up June 30.
