Dahlia Tuber Planting Method and Process Explained in Detail

For dahlias, growing them in pots is generally more difficult than growing them in the ground. To plant dahlias, we can divide out their tubers, then let the cut wounds dry, and afterward plant them in pots. Today, the editor will share with you the method and process of planting dahlia tubers.

1. First, we still need to make a drainage layer at the bottom of the flower pot. You can use stones or large-particle expanded clay, or even broken tiles.

2. Next, cover the drainage layer with a layer of soil, then evenly scatter a layer of pure green organic fertilizer——sheep manure, on top of the soil as a base fertilizer.

3. Then continue to cover with a layer of soil, completely covering the scattered nutrients, until most of the pot is filled.

4. Immediately after that, place the dahlia tuber whose wounds we dried in advance in the middle of the flower pot. Be careful to control the planting height, and do not let its sprouts be buried in the soil either, otherwise it can easily cause rot.

5. After placing the dahlia tuber in the pot, continue filling with soil while making sure the sprouts face upward, until there is still about a 2 cm gap from the rim of the pot. At the same time, be sure to let the sprouts on the tuber remain exposed above the soil surface; do not cover them completely.

6. After planting the dahlia tuber, the original next thing we need to do is water it. When watering, first add a few drops of rooting liquid to the water, about 5-6 drops is enough; do not add too much.

7. After stirring the rooting liquid and clean water evenly, we water thoroughly for the first time as the settling water. But when watering, you must be very careful. To avoid the water flow scattering the loose soil and washing the dahlia sprouts out, we can place a small plastic bag in the pot, then slowly pour the water onto the plastic bag until the water soaks through the entire flower pot.

After watering, place the flower pot in a place with sufficient light for care. Because the dahlia itself has sprouts, or has already grown sprouts, and has adapted to the light environment, the new sprouts will not grow too tall. Usually it only grows very tall when there is a lack of light, and it is also prone to lodging.

Potted dahlias are most prone to leggy growth due to insufficient light, so if the plants we buy lack light, they often grow to more than 1 m tall. Therefore, during normal care, be sure to provide sufficient light, and you can regularly apply a growth retardant once to the plant until flowering ends. Generally, spray the growth retardant once every half month, and using it 3 times in a row is more appropriate.
