Plant out sweet pea seedlings
Knock sweet peas out of their pots and plant them into a sunny border or pot with rich, moisture-retentive soil or compost. They will need a structure of pea sticks or netting they can scramble up to flower through the summer. Keep them well watered as they establish and pinch out the tops if they are getting leggy.
Sweet peas are hardy enough to cope with some frost but need protection from slugs and snails.
