They are now growing away very strongly and I think I might transplant them into the bed where the summer broccoli is, since I will be digging up the broccoli plants in a few days' time. Originally I had planned to grow the peas in those pots (this is why I chose a compact variety), but I've changed my mind!
They will do better in the bed, and it will be easier to give them some support. Unless you grow the very short varieties, you do need to provide something for them to climb up. I'm not planning to erect a fancy support structure like I did for my first batch of peas. I thought I might try a wigwam of bamboo canes, or maybe even just a circle of plastic clematis netting. I'll decide nearer the time...
I expect we still have 8 - 10 weeks of decent growing weather left this year before it gets cold, so I hope the peas will come to maturity within this time.
