When to prune dahlias

Dahlias are suitable for pruning in spring and autumn, and the remaining flowers also need to be properly pruned after flowering, which can reduce nutrient consumption and promote better growth of the plants.

How to propagate dahlia trimmed branches by cuttings : Cut off part of the branches and roots, insert them into the bed, and cultivate them to become independent new seedlings.

There are two methods of cutting: branch cutting and root cutting. The survival rate of autumn cutting is high. Spring cutting should be carried out as soon as possible after the soil thaws. When inserting, dig a ditch and irrigate it, then insert it. The depth should not be less than 10 cm. The angle between the top of the plug and the vertical line of the base should be maintained at about 30 degrees. The thickness of the soil should be flat with the top of the scion. Pay attention to covering the grass to prevent cold in autumn.

Dahlia pruning

1. Pruning branches: When caring for dahlias, you need to prune dead and diseased branches, and prune weak branches during the growth period to avoid consuming excess nutrients. Pruning can promote the germination of new branches.

2. Pruning flowers: Dahlias have a relatively long flowering period, so the withered flowers need to be pruned after flowering to avoid wasting nutrients and affecting the opening of new flowers. If you want the flowers to bloom more brightly, you can leave the top buds and side buds and cut off the lower buds. This will help give all the nutrients to the upper buds, making the flowers bigger and brighter.

Dahlia Pruning Tips

1. Only keep one terminal bud: In this way, the dahlia will only bloom one flower. This pruning method helps to fully supply nutrients to the dahlia. When it blooms, not only are the flowers large, but the colors are also very bright.

2. Keep 1 to 2 side buds below the top bud : Keep these two side buds of dahlia to prevent the top bud from accidentally blooming. The side buds can be replenished immediately, and then the remaining side buds growing on the main trunk can be removed.

3. Keep multiple flower buds: Because dahlias have many flower buds, pruning in this way will not cause loss of flower buds, allowing the flowers to bloom and cover the branches, but the size and color of the flowers will be slightly worse.

Tips for pruning dahlias

When there are too many dahlia flowers, the quality of the flowers is poor and the flowering period is short, so the number of flowers should be properly controlled, and the flowers need to be pinched in time to promote branching. When the branches grow, the small buds should be constantly wiped off, leaving only the top buds to promote the strength of the branches.
