DAHLIAS CARE:

Dahlia tubers are not winter hardy, meaning they cannot withstand frost. Therefore, plant the dahlia tubers after the last frost period in the spring, approximately in May or June. It is also possible to pre-pluck the dahlias in a bright room in the house or in a greenhouse in March or April. Plant the tubers in nutritious, humus-rich soil in a sunny spot. Plant the dahlia tubers 2-3 centimeters below the surface so that they can feel the warmth of the sun. Plant the tubers with the stem upwards and approximately 30-40 cm apart. If dahlias are planted too close together or in the shade, they will look for light. In that case they become longer and weaker. Good luck and have fun with the dahlias!
