It is easy to grow and offers a strong decorative effect, making it suitable for both beginners and experienced gardeners.

Sowing depth

Sow the seeds at a depth of 3 to 4 cm. This provides good conditions for quick germination and strong rooting of young seedlings. Sowing too shallow can leave seeds at risk of drying out, while sowing too deep can make it harder for seedlings to reach the surface, so it is best to keep to the recommended depth.

When to sow outdoors

The best time to sow outdoors is March or April, when the soil is slightly warmed and the risk of frost is low. Sweet peas cope well with the cooler start of spring, and earlier sowing supports stronger growth and more abundant flowering in summer. If you want earlier flowering, you can start seeds in containers under cover and transplant outside once colder weather has passed.

Spacing

Keep a spacing of 10 to 20 cm between plants. This gives the shoots room to grow and helps the flowers form a dense, impressive display. Overcrowding reduces air flow and can encourage problems, so giving plants enough space supports healthy growth and better flowering.

Flowering period

Sweet peas flower from June to September. The long flowering season keeps gardens, balconies, and terraces colourful through the summer. Regularly removing faded flowers encourages new buds, helping the display continue until autumn.

Growing tips

Sweet peas grow best in sunny positions sheltered from strong wind. They prefer fertile, free-draining soil that is slightly limy. Before sowing, soak the seeds for a few hours in warm water to help them germinate faster and produce stronger seedlings. Water moderately, keeping the soil lightly moist but not waterlogged. Regular weeding and gently tying young shoots to supports helps keep the plants in good condition and guides their growth. With their tendrils, the stems climb readily over supports, trellises, and fences, creating a light and elegant effect with very little effort.
