There are two ways to overwinter dahlias. First, the roots can be dug out. Specifically, after the frost, cut off the main stem, then pour out the pot soil and take out the roots. The roots should be wrapped in sand and placed in an environment with a temperature of about 5 degrees. The second is not to dig the roots. Specifically, cut off the main stem and put the potting soil together in an environment with a temperature of 5-10 degrees, and keep the soil dry. Note that no matter which method is used, it cannot be placed in a place where the temperature is too high to avoid premature germination.

1. How to survive the winter by digging out the roots

Dahlias are not very cold-tolerant, and the temperature in winter is relatively low, so they must be treated with heat preservation in time. After frost, the main stem above the roots should be trimmed off, the soil in the pot should be poured out, and the roots should be taken out. The roots are not cold-resistant, so bury them in sand. It should also be placed in a place where the temperature is about 5 degrees. Be careful that the temperature is not too high, otherwise the roots will germinate prematurely and will affect the growth of the next year.
