Growing tips

  • If sowing first in seed raising mix take extra care when transplanting as Sweet peas resent root disturbance. 
  • If heavy rainfalls are expected close to planting time, start the seeds off in toilet paper rolls filled with damp seed raising mix. Don’t be tempted to water the seeds for at least a couple of days after sowing and only apply small amounts of water to the seeds to keep the soil lightly moist. Once germinated, plant the toilet paper rolls containing the young plants directly where they are to grow and water in well.
  • Apply some mulch around the base of the plants to help retain soil moisture.
  • Sweet Peas are traditionally sown on St Patricks Day (17 March) however can be sown later in autumn in many areas around Australia.
  • For maximum sunlight exposure have the trellis running in a north-south direction.
  • You can create little Sweet Pea tepees in the backyard which is a delight for kids.
  • Pick blooms regularly to promote further flowering.
  • Once flowering has finished and the plant begins to wither, dig them directly into the soil as a green manure which adds nitrogen to the soil.
  • Do not consume the fruits or seeds of the Sweet Peas as they are poisonous if eaten.
