How should dahlias be cared for in winter so they can survive the winter safely?

Dahlias bloom beautifully and generously, with neatly arranged petals, and are easy to grow, so many people keep one as a potted plant. But they are not cold-tolerant, and low temperatures will cause their stems and leaves to wither, making winter a severe test for them. So how should we insulate and care for them in winter? Follow the editor below to take a look at dahlia winter care methods.

Preparations for the Start of Winter

Preparations for the start of winter are the first step for dahlias to survive the winter safely, and also the most important step. After the flowers fade in autumn, the plant will gradually wither as the temperature drops, until it completely dies. At this time we cut off the withered stems and leaves, generally leaving the plant 10-15cm, and move the pruned potted plant to a warmer indoor environment, taking good insulation measures.

Light

Dahlias like an environment with sufficient light, and winter is no exception; they need sufficient light time. After cutting off the stems and leaves, do not place the potted plant in a hidden and dim environment, as this will cause the plant to die from lack of light. Let it receive sufficient light, which is good for sprouting and growing the following year. If there is insufficient light, an incandescent lamp can be used to supplement light.

Watering

The winter climate is relatively dry, and generally other plants do not need watering, but dahlias are not drought-tolerant and are averse to waterlogging, so in winter they need a little water, but not too much; just keep the potting soil from being too dry. If you forget to water or do not know how to control the amount of water, it is not a big deal, because dahlia roots and tubers have a water-storage function, so even if we do not water, it will not have any effect on them.

Storage Environment

Storage is also extremely important for dahlias to survive the winter safely, but it is not as complicated and troublesome as imagined; just keep the storage environment no lower than 1 degree, with the best being 1-5 degrees, and the storage environment must be dry and ventilated.

The above are the dahlia winter care methods. Have you all learned them? Dahlias have a strong demand for light, needing more than 16 hours of light a day, so friends who grow them should pay attention to this.
