Pinching out sweet pea seedlings
Arthur shows you how to pinch out your sweet pea seedlings to stop them getting leggy, and help create healthy, bushy plants that will transform your garden with colour and scent when they flower later in the year.
These sweet peas sown in December are still small in late March, which is good because it means they have been putting their roots down into the roottrainers without getting too tall and leggy.
To prevent the seedlings from getting leggy, pinch out the top of the seedling, which will make them grow auxiliary buds and get bushy and strong. Sweet peas are hardy annuals, so once the seedlings are established, they can handle a late frost.
Make sure you keep your sweet pea seedlings moist and feed them with liquid seaweed feed both while in root trainers and once planted out in May.
