Growing Dahlias from Tubers
Have you ever grown dahlias from a tuber?
Old Fashioned Beauty
I've had a English cottage style garden for the last fifteen years in Colorado Springs, Colorado and although I didn't grow dahlias every year this year I purchased dahlia tubers from Swan Island Dahlias in Canby Oregon (make sure to watch their video on Dahlia varieties below) and enjoyed the whole gardening season from the time the first tiny green sprout broke through the soil. Depending what part of the country you live in, dahlia tubers are planted from March through the first week of June. In my area of the country a late May early June planting time was recommended.Dahlias are a beautiful and prolific cut flower, I've had a summer full of blooms that fill my home with color and beauty. And don't forget to cut off spent/dead blooms, the more you cut the more dahlia buds bloom.

Quick Guide to Growing Dahlias
- Prepare the soil
- Plant the tubers
If you want your dahlias to have the best chance plant your tubers in a location in your garden that gets at least 6-8 hours of sun a day. Dahlias love sun, so if you choose wisely you'll have a garden full of blooms.
The best time to cut dahlias is early morning. To keep the blooms lasting 4-6 days Swan Island Dahlias recommends the "hot water treatment." Essentially what this means is immersing the cut stems in 160-180 degree water until the water is cool. Once the water is cool you will see a change in the stem color, at this point cut the stem to any length you desire. Cut flower food is recommended. If you don't use the "hot water treatment" expect that your cut blooms with last about 2-3 days.
