If you want showstopping dahlia blooms this summer, there is one job for you to remember. That is disbudding dahlias, a technique that involves removing side buds to concentrate energy into the main terminal bud.
It may sound cruel to remove buds that will otherwise produce flowers. However, disbudding dahlias gives you larger blooms on a longer stem. This is ideal if you grow dahlias as cut flowers or want to exhibit them in a local show.
