Can dahlias be propagated by cuttings?

The propagation methods of dahlia include bulb propagation, sowing propagation, and cutting propagation. Autumn sowing is better than spring sowing. Spring sown dahlias are difficult to bloom due to their short growth period. Even if they bloom, the flowering period is very short. Bulb propagation has a high cost, so cutting propagation is the most commonly used method.

Dahlia cutting propagation

Dahlias can be propagated by cuttings, so that you can get a lot of seedlings in a short period of time. Dahlias are very easy to propagate by cuttings. This method is very simple. Of course, the timing of cuttings must be chosen correctly, otherwise it will affect the later growth.

Dahlia cutting time

The best time for dahlia cuttings is in spring and autumn. The survival rate in autumn is higher than in spring because dahlias germinate late in spring. Using tender heads for cuttings, coupled with the increasing temperature in spring, can easily cause the tender stems to rot, making management very difficult.

How to propagate dahlias by cuttings

1. Branch selection: When taking dahlia cuttings, you can choose the lower side branches, or small side branches with smaller flower buds that are not capable of producing high-quality flowers. Of course, you can also directly take the strong top branches, but this will affect the flowering of the finished plants, and it is not certain whether they can survive.

2. Cutting medium: Dahlias do not have high requirements for the cutting medium. It is recommended to use a 1:1 ratio of peat and perlite, or a 1:1:1 ratio of peat, perlite and plain soil. In short, it should not contain fertilizer.

3. Cutting management: Dahlia branches are relatively fragile, so before cutting, you need to poke a hole with a wooden stick, put the branches in, and then water them thoroughly. After cutting, just place them in a ventilated place where direct sunlight cannot reach them.
