1、 Soil

When potting dahlias, five parts of garden soil, two parts of rotten leaf soil, two parts of river sand and one part of rotten organic fertilizer can be mixed and cultivated evenly. It should be noted that after the bulbs are planted in the flower pot, the bulbs should be completely buried in the soil without exposing the soil surface. After planting, pour water and put it at a constant temperature of more than 15 degrees, and sprout in about one week to ten days. Once germinating, it should be placed in a well lit environment, which has high requirements for light

2、 Watering

Attention should be paid to the watering of potted dahlias. Outdoor cultivation, especially in summer, has a large amount of evaporation, so watering must be timely to prevent dryness. The evaporation of indoor planting water is restrained to some extent, and the potted root system should be avoided from rotting

3、 Temperature

Dahlia is a plant that is afraid of both cold and heat. When the temperature exceeds 25 degrees in summer, it should be placed in a cool and ventilated environment for high-temperature protection. When the temperature at night is lower than 10 ℃, it is also necessary to prevent low temperature

4、 Fertilization

In the cultivation process, in addition to applying enough base fertilizer to the soil before bulb planting, thin liquid fertilizer shall be applied to it every 10 days during the growth period

5、 Pest control

Dahlia is relatively prone to diseases and insect pests. We should observe frequently. Once there are signs, we should intervene in time to prevent unnecessary effects of diseases and insect pests
