How do I Care for Dahlias?

Our high quality dahlia tubers are harvested in Holland and kept cool until they are shipped to the US to our customers. Dahlias should be planted in the spring when there is no danger to frost. Check your frost dates and plant accordingly. They prefer drained soil but need to be watered regularly. Plant them in full sun about 12 to 18 inches apart and 6 to 8 inches deep. Pinch top of dahlias above the 4th set of leaves for more blooms.

How do I store my Dahlias over winter?

You can store your Dahlias over winter by using a ventilated box or basket. Take each clump of tubers and fill the box with slightly moistened sand, peat moss or vermiculite and place them in a cool, dry location. The temperatures should remain between 45 and 55 degrees F. Make sure to check your tubers periodically throughout winter to ensure your Dahlias are not rotting or drying out.

Tips & Growing Instructions

Dahlias can be started indoors in individual pots with damp peat moss and vermiculite. You must use caution when transplanting them outdoors. Plant dahlias outdoors after all danger of frost has passed. Choose a sunny site with well-drained, sandy soil. Dig a hole a little larger than the 2" you'll need to plant the Dahlia. Amend soil with peat moss or compost. Replace about half the soil, then place tubers flat and cover with remaining soil. Space tubers 12-36" apart depending on variety. Water after planting and not again until shoots appear. Stake plants. As plants grow increase watering. Fertilize sparingly. Pinch and disbud dahlias for later and larger flowers. Buds tend to grow in threes; two-sided ones should carefully be pinched to develop the central bloom. This is especially important with border or pot plant dahlias. If the plants are not pinched back, they will not retain their low compact size.

tulip In areas with winter freeze, carefully dig the tubers in fall after the frost kills the foliage. Cut the stalk approximately 6" above the tuber. Dahlias should be dried for only a couple of hours before storing in plastic-lined shallow boxes with a blanket of vermiculite or peat moss. Hardy in Zones 8-10.
