To grow sweet pea plugs in pots outdoors, they must first be hardened off and given some protection. A sheltered spot or a frame outside for a few weeks is ideal. To get the best blooms, a method exhibition growers use is to nip out the energy-sapping side shoots and tendrils.
You Will Need
- Sweet pea plugs
- Multi-purpose, peat-free compost
- Loam-based compost
- Pea sticks
Sweet peas thrive in pots. Choose a rich peat free potting compost and mix in loam-based compost to provide extra water retention. Firm in the compost well.
See our guide to the best peat free compost to find a range that suits your needs.
Use pea sticks, wire mesh or pea netting for support. Plant the plugs close to their supports. Individual plants grown as one plug can be carefully separated.
Soak the newly planted plugs and once they start to grow away use a liquid feed regularly to encourage strong growth and continuous flowering. Here are some tips on making your sweet peas last longer.
