How to maintain dahlias in winter

Dahlia flowers are beautiful and generous, petals are neatly arranged, easy to grow, many people will raise a pot as a potted plant. But it is not cold-resistant, low temperature will make its stems and leaves wither, winter is a severe test for it. So how should we take care of its heat preservation in winter? let's follow the editor to take a look at the winter maintenance methods of dahlia.

Preparation for winter

Preparation for winter is the first and most important step for Dahlia to survive the winter safely. After the flowers wither in autumn, the plant will wither gradually with the decrease of temperature until it dies completely. At this time, we cut off the withered stems and leaves, generally leaving plants 10-15cm, and transplanting the cut potted plants in an indoor environment with higher temperature to keep warm.

Light

Dahlias like the environment with plenty of light, and it is no exception in winter, so they need enough light time. After cutting off the stems and leaves, we should not put the potted plant in a hidden and dark environment, which will cause the plant to die due to lack of light. Let it receive sufficient light, which is conducive to germination and growth in the coming year. If the light is not enough, incandescent lamps can supplement the light.

Watering

Winter climate is relatively dry, generally for other plants do not need watering, but dahlias are not resistant to drought, waterlogging, winter need to water a little, but should not be too much, just keep the pot soil will not be too dry. It doesn't matter if you forget to water or don't know how to control the amount of water. Dahlia roots have the function of storing water, so even if we don't water it won't affect it.

Storage environment

Storage is also very important for dahlias to survive the winter safely, but it is not as complicated as imagined, as long as the storage environment is not less than 1 degree, the best is 1-5 degrees, the storage environment must be dry and ventilated.

These are the winter maintenance methods of dahlias. Have you all learned that dahlias have a strong demand for light, which requires more than 16 hours of light a day? breeding friends should pay attention to this.
