Like beetroot, take a modular tray and sow 3-4 peas per module.
Peas don’t like disturbance to their roots. For this reason, many recommend growing peas in a length of guttering, and when they are ready to plant outside, simply sliding them out of the guttering. I have tried this method with little success, it’s a difficult thing to coordinate from start to finish. My favourite way to sow peas is multi-sowing. Like beetroot, take a modular tray and sow 3-4 peas per module. As peas are larger plants, you will need larger module trays or small pots.
