Grower's Guide to Dahlia Bulbs/Tubers
Dahlias are favorites for the summer garden because they are easy to grow and provide weeks, and sometimes months, of colorful blooms. They're also favorites for cut flower displays. To get the most out of your dahlia flowers, follow these tips on how to plant dahlia tubers.
When to Plant Dahlias
Dahlia tubers are planted in the spring after the last spring frost date in your area. In more northern regions of the country, dahlias are sometimes started indoors and transplanted to the garden after danger of frost has passed.
Where to Plant Dahlia Tubers
Dahlia bulbs (or tubers) grow best when planted in full sun (six or more hours of direct sunlight daily), and the best soil for dahlias is well-drained and rich in organic matter. When planting dahlias tubers, take into account their mature height and spread.
How to Plant Dahlias
To determine the dahlia planting depth, dig a hole that is twice as deep as the length of the dahlia tuber. Add dahlia fertilizer (Van Bourgondien 100% Natural Bulb Food is recommended) to the bottom of each hole. Cover the tuber with about 1 ½ inches of soil. Water well. After the dahlia sprouts appear above ground, water weekly. Dahlias should be staked or caged while still small.
How to Grow and Care For Dahlias
For the most part, dahlias are fairly trouble free. Some gardeners pinch and deadhead for improved production, but dahlias will produce flowers without taking these steps. Deer will often choose other plants first before nibbling on dahlia shoots. Some pests to watch out for include slugs, mites and aphids. Powdery mildew may become a problem in the fall.
