Sweet Pea (Spencer) Blue Velvet | Lathyrus

After the risk of frost has passed, and before spring planting our 9cm sweet peas, incorporate lots of well-rotted organic matter in the planting area and backfill. Once planted out, keep sweet peas well-watered, especially during dry spells, as they dislike drying out. Tie in the stems regularly to their supports to keep them upright and prevent tangling. Feed every couple of weeks with a high-potash fertiliser once flowering starts to encourage continuous blooms.

Remove faded flowers promptly to prevent seed pods forming, as this will prolong flowering. Keep an eye out for pests such as aphids and treat early to prevent damage. Regular picking not only keeps the display going but also provides plenty of blooms for the house.
