How do dahlias spend the winter? Do you dig them out in winter?

It is recommended to repot it in spring, which is more conducive to recovery and will not affect flowering. Plants ready for repotting are cut off water in advance to facilitate pot removal. After taking off the pot, we should prune the rotten roots, withered roots and poor roots, and disinfect and dry them for later use. Flowerpots should be larger than the original ones, and they should be potted directly after they are ready. When potting, part of the soil is put first, and the soil is added and compacted when the plant is put. If the soil mass does not disperse, it can be directly filled with soil.
