How to pinch carnations
Pinch your carnations to help flowers grow.
Pinching carnations as they grow encourages the growth of lateral stems, which means more flowers will grow. Pinching is especially important if you want to grow flowers for cutting.
Pinching also helps the plant to grow bushy rather than as a single tall stem, which some gardeners prefer. The height at which you pinch the plant stem off is the height at which it should start to bush from.
