How to propagate dahlias
For most women, the topic of how to propagate dahlias and the methods and timing of dahlia propagation is a plant-related interest. Detailed content is shared below.
To make dahlias bloom more flowers, propagation is a very crucial step. Generally, it can be easily completed in five steps. First, the cuttings must be selected properly, and it is important to note that the branches should not be left to dry in the sun. The propagation medium can be vermiculite, which does not easily breed harmful bacteria. Attention should also be paid to changes in the care environment, with regular transplanting and fertilizing to ensure dahlias are grown well.
1. Selecting the cuttings properly
Choosing cuttings seems simple, but poor selection can lead to a lower survival rate. Choose branches that have grown for a year or have just bloomed, as they have strong growth and are easy to root, with a high survival rate. Avoid randomly selecting branches.
2. branches should not be left to dry in the sun
Dahlias are herbaceous plants, and there is no need to let the cuttings dry out during propagation. After cutting, soak the branches in a mixture of root stimulant and carbendazim for 30 minutes, then the cuttings can be planted.
3. Propagation medium
The propagation medium can be vermiculite because it has good water retention properties, which is beneficial for rooting. It contains no nutrients, does not easily become infected, and does not easily breed bacteria or cause black rot. Note that after using vermiculite for propagation, attention should be paid to proper post-planting care.
4. Care environment
The newly propagated branches must be properly cared for. Do not expose them to direct sunlight or keep them in the dark. Especially avoid placing them in areas without proper ventilation, as this can lead to black rot. They should be placed in a shaded and well-ventilated area, with the leaves misted with water daily to keep the soil moist for 15 days.
5. Transplanting and fertilizing
When the branches have rooted and the roots are about 3cm long, they can be transplanted. Care should be taken not to damage the roots. After transplanting, water once to ensure good drainage. When the potting soil is dry, fertilizing can begin. During the growing season, apply a multi-nutrient organic compound fertilizer at least twice a month to ensure adequate nutrition and rapid growth.
