Pruning is the process of removing dead, diseased, or unwanted plant material. When it comes to dahlias, pruning is an important part of their care and maintenance. Pruning can help to promote bushier growth, encourage more blooms, and improve the overall health of the plant.
There are two main types of pruning that can be done on dahlias: deadheading and cutting back. Deadheading is the process of removing spent blooms from the plant. This helps to encourage the plant to produce more flowers and prevents the plant from putting energy into producing seeds. Cutting back is the process of removing entire stems from the plant. This is typically done in the fall or winter when the plant is dormant. Cutting back helps to reduce the size of the plant and make it easier to manage. It also helps to promote new growth in the spring.
