Good enough to eat – peas
You can make a head start now if your soil is cold and wet by sowing early peas in some guttering in the greenhouse.
Just buy a strip of house guttering, cut it into lengths and place it on your greenhouse staging. Half fill the guttering with potting compost.
Sow peas about 3-5cm apart, covering them with more compost, water with a watering can fitted with a rose and place on the greenhouse staging.
Once the seedlings are around 10cm, they will be ready to plant outside in a sunny spot in soil with added organic matter.
Use a spare piece of guttering to dig a trench and then slide the seedlings, compost and all, out of their guttering and into the space. Firm the ground around them and water them in. Protect them from pigeons by covering them with netting supported by stakes.
