Love the sight and scent of sweet peas? Sweet peas (Lathyrus odoratus) are one of the easiest plants to growand while you won’t get a floral show until spring, now isthe time to be sowing seeds. You can grow sweet peas in a fragrant teepee, create a wall of colour by growing them up a fence or if you're short on space, plant dwarf sweet peas in pots, window boxes or hanging baskets.


How to grow sweet peas in a garden

  1. Choose a well-drained spot in the garden that has full sun and is sheltered from the wind.
  2. Enrich the soil with some compost and Yates Dynamic Lifter Organic Plant Food before planting.
  3. Sow into damp soil where the sweet peas are to grow and lightly cover with soil. Tall growing varieties will need a support to climb up.
  4. Do not water for a couple of days after sowing. If the soil becomes dry, water gently to keep it slightly moist while the seeds are germinating.
  5. Once the seedlings are established, feed regularly during the growing and flowering season with Yates Thrive Rose & Flower Granular Plant Food. TIP: For an added boost, apply Yates Thrive Natural Fish & Seaweed+ Plant Food Concentrate.
  6. Pinch out first buds to encourage bushier plants.
  7. Remove any spent flowers to prolong the display.

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 organic mulch around the base of the plants to help retain soil moisture.
  • 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.
