Sweet pea

Lathyrus odoratus


Sweet peas are easy to grow and produce lots of fragrant flowers that are equally beautiful in the garden or in a vase.


  • Follow The Steps!

Getting started

  • Peel the sticker off and find your soil tablet, leave it in the tray. 
  • Pour 60ml of water into the hole with the soil tablet. 
  • All the way to the top of the hole.Let the soil tablet absorb all the water for 5 minutes. 
  • Mix the water into the soil with your fingers to make a even wet mixture. 
  • Remember to wash your hands when you’re done.

How to keep your Little Garden healthy

  • Place the tray in a place with enough light, but not directly in the sun. 
  • Check the soil every day. If the soil feels dry and crumbly, pour a small amount of clean water over the surface. 
  • You should see a little plant appear from the soil in 1 or 2 weeks, which means the seeds have germinated and will be ready soon to move into a bigger pot or garden. 
  • You can choose the strongest-looking one if more than one little plant grows.

When your seedling is ready to go in the garden

  • Shift into the garden or pot when the sweet pea is about as tall as your hand (in approx. 1 month). 
  • You can harden off your sweet pea seedling by putting it in a warm and sheltered spot for 1-2 hours a day and return inside for the night. Do this for 4-5 days, leaving it outside for a little longer each day before you shift it out into the garden forever.

Planting best practice

  • Give your sweet peas full sun with moist but free-draining soil. 
  • Sweet peas are climbers, so give them something to scramble up! Plant at the bottom of a trellis or fence, or make a tripod by tying three garden stakes together at the top. 
  • Grow them in hanging baskets will be a good option too.

Look after your plant while it’s growing

  • Water plants regularly, especially in dry weather, and at least once a fortnight once the buds start to appear. 
  • As soon as plant is about 15cm high, you can thin your sweet pea by cutting off the growing tip to encourage more of the flowering side shoots to form.

Harvest time

  • Once flowers bloom, they’re ready to pick! Keep picking flowers so that new blooms are produced. 
  • If flowers are left on the plant to die, seedpods will form, which will slow down and stop the flowering. 

  • Little tip:At the end of the season, let a few seedpods form and save the seed inside to plant the following year!

Watch out

  • Slugs and snails love to nibble on sweet pea seedlings, so create your own pest protection, lay out bait or pick off these slimy pests. 
  • Ensure the plant has good air circulation and remove affected leaves, then spray weekly with a milk and baking soda spray. Sweet peas can be prone to powdery mildew, a fungal infection which will cause a grey film on the leaves, especially under hot and humid conditions.
