In 1699, a Sicilian monk called Franciscus Cupani sent seeds of the local wild sweet pea to his friend, English schoolmaster Dr. Robert Uvedale. This was the beginning of a love affair between gardeners and sweet peas that continues to this day. 

If, however, you want to grow the authentic sweet pea as nature first made it, look for Sweet Pea Original. This small, bi-coloured flower, with its incredibly strong scent, is something truly special. Its subtle charm is very endearing.

Growing Sweet Peas

St Patrick’s Day, March 17, is the traditional date for sowing sweet peas, but this date should be regarded as a guide, not a law. In cooler areas, sweet peas are often better sown in spring. Some varieties are recommended for spring sowing because they‘re late (i.e. summer) blooming.

In warmer areas, it’s safer to wait until April or early May to sow sweet peas. Once the soil’s cooled down, there’s far less risk of the seeds rotting away before they germinate.

Grow sweet peas in a sunny spot with good drainage. Make sure there’s some support for climbing varieties and choose an east-west orientation so they get as much sun as possible. Before you sow, add some complete fertiliser such as Yates Dynamic Lifter Organic Plant Food to the bed and, in most areas, a small amount of Yates Thrive Natural Garden Lime. Water the soil well the day before planting and sow into a moist bed. Try to avoid watering again until after the seedlings have emerged. As the young seedlings appear, poke in some small twigs that will help guide them to the climbing support.


Once the sweet peas, begin growing, feed weekly with Yates Thrive Natural Fish & Seaweed+ Plant Food Concentrate. Once they start to flower, pick them as much as you like. If any pods are allowed to form, this sends a signal to the plant that stops it flowering.

The most popular Yates sweet pea is Sweet Pea Colourcade, a cheery blend of mixed colours. It blooms early in the season, thus avoiding any late spring hot spells. Sweet Pea Bijou Semi Dwarf is a popular, low-growing (to 60cm) variety that suits smaller gardens. There are many other sweet pea varieties available in the Yates range so it’s worth checking out the autumn seed stands.

One of the sweet pea’s great advantages is that it’s a member of the legume family so the plants are able to feed themselves by making use of the nitrogen in the atmosphere. This means that, once the flowering’s finished, it’s good to dig the plants into the soil where they’ll add extra goodness.

Sweet peas can suffer from powdery mildew fungus, so always have Yates Rose Gun Spray Ready to Use in the garden shed. As well as controlling fungus, Yates Rose Gun Spray Ready to Use will help take care of insect pests and mites.
