Planting Sweet Peas

Sweet Peas are a fragrant spring flowering annual, native to Italy. They have one of the most enchanting flowers, delicate and fragrant, perfect in garden or admired in a vase.

Tradition dictates that March 17th (St Patrick's day) is the time to plant Sweet pea seeds. Have you ever wondered why?

Planting PEA seeds on St Patrick's Day is an old American tradition. As you will need the 'luck of the Irish' to get plants to grow while there is still snow on the ground!!!

For us here in Australia, we still follow this tradition because lets be honest here in Ipswich we need the 'luck of the Irish' to get sweet peas flowering and looking good. Normally, March is still too warm to start our winter gardens here in SE QLD.

Instead I use time as a reminder to prepare my soil.

Noel Burdette used to live here in the Ipswich region. Years ago he offered me this great advice about preparing the soil for Sweet Peas. This information is for sweet peas but can be applied to any peas.

 

Noel's Sweet Pea Advice

  • Sweet peas like a full sun position in the garden with plenty of airflow to minimise any fungal concerns.

  • They also enjoy a slightly higher level of pH in the soil, somewhere between 7.5 - 8.5. You can adjust your pH by applying a generous amount of Dolomite (provide much needed Magnesium) or a light dusting of Lime (as the calcium content is important).

  • They love well composted soil. We use Searles Compost but a little well aged sheep, cow or chicken manure worked into the soil would also help to encourage good drainage, yet adequate moisture retention.

  • Usually around mid April is a good time to plant out your seeds or the first quarter moon after St Patricks Day. Noel recommends to soak them overnight in a little water with a small amount of Condi's crystals (usually get this at a chemist) as this will encourage a higher percentage of germination.

  • After planting the seeds in the ground, water them in once and don't water again until they are "up and out "of the ground.

  • Pinch out any lateral growth in the early stages as what you're looking for are strong, upright plants that will then branch out as they get older and provide long lasting, fragrant blooms from late winter and into spring.

  • Fertilise your Sweet Peas with Organic Link when first growth appears and then alternating fortnightly between Triple Boost and Silica and Potash Liquid fertiliser.

All sweet peas are climbing. Some are dwarf climbers (only grow to about 50cm) and others can grow to over 2m.  

With all types of sweet peas, ensure they have somewhere to stretch their tendrils (fences or tepees) or maybe try them in a hanging basket and let the tendrils hang down.

Trevallan stocks Eden Seeds (non-hybrid open pollinated old fashioned seeds) Sweet Peas and Pohlmans Sweet Pea Seedlings. This year we have two choices in the seeds and the seedlings. The seedlings aren't usually available until April.
