How to care for dahlias in winter? Do these things well for a safe overwintering

Dahlias bloom beautifully and elegantly, 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 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 the winter care methods for dahlias.

Preparation for the start of winter

Preparation for the start of winter is the first step for dahlias to overwinter safely, and also the most important step. After the flowers fade in autumn, the plant gradually withers as the temperature drops, until it dies completely. At this time we cut off the withered stems and leaves, generally leaving 10-15cm of the plant, and move the trimmed potted plant to an indoor environment with a higher temperature, and take good insulation measures.

Light

Dahlias like an environment with plenty of light, and winter is no exception, requiring 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 beneficial for sprouting and growth the next year. If there is insufficient light, an incandescent lamp can be used to supplement the light.

Watering

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

Storage environment

Storage is also extremely important for dahlias to overwinter safely, but it is not as complicated and troublesome as imagined; you only need to keep the storage environment no lower than 1°C, with 1-5°C being optimal, and the storage environment must be dry and ventilated.

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