1、 Budding

The tuberous roots of Dahlia need to be sprouted before planting. In early spring, its bulbs are usually taken out from the storage environment in March and April, trimmed off the damaged and dead parts, and then buried in the wet fine sand. Put it in the germination chamber with constant environment for germination, or put it in a warm corner. The light doesn't need to be too strong. About 5-7 days, you can obviously see Bud Germination from the rhizome

According to the sprouting and germination, if the root tuber is relatively small, it can be planted directly. If the root tuber is relatively large, the root tuber can be cut with a sharp knife or scissors to achieve the purpose of reproduction

2、 Cultivation

Dahlias that have been treated with germination can be cultivated normally. They can be potted or planted in the field. Both potted and ground plants should give it enough growth space. Generally speaking, potted plants should be at least 20 cm above the flower pot

The planting hole for ground planting should not be less than 20cm. The soil should be loose, fertile and breathable loam. When planting, pay attention to put its buds on the upper part, so as to make it grow normally

3、 Fertilizer

In order to meet the demand of Dahlia for fertilizer, a certain amount of rotten organic fertilizer can be put into the planting hole or the bottom of the flowerpot as the base fertilizer

4、 Establishment of pillars

When planting, because its branches are relatively high, there are some varieties, especially giant and large flower types, and its flower heads are also very heavy. Therefore, it is necessary to deeply bury a support support pillar about five or six centimeters on one side of the planting ball. When it is ready to bloom, tie the plant on the pillar to prevent it from falling down

The pillar of Dahlia should be buried before bulb planting, because when the support is needed in the later stage, when the pillar is nailed, because its root system may be too large and cause damage to the root system, which is a problem that should be paid attention to in its growth. After planting, pour water twice and turn to normal water and fertilizer management
