Dahlia Flower Collections for the Garden

Plant Dahlia Collections for a Garden Full of Color

Save time and money by purchasing dahlia collections. Collections of dahlias typically cost less than if you purchase individual tubers and are an easy way to acquire a garden full of color without a lot of work. Look for collections that are either color-coordinated or are grouped by height of plant. Some dahlia collections are also labeled as 'cutting' collections for gardeners who want dahlias that make great cut flowers.

1. Plant dahlia tubers only after the last frost has passed for your area. Dahlia tubers will freeze! The
   recommended soil temperature for active growth is 55 degrees or higher.
2. Plant dahlia tubers so that the stem of the tuber is just above the soil level. Be careful not to plant the tubers too deep. Cover lightly with topsoil and water well.
   
3. Once the tips of new growth start to emerge, provide ample water on a regular basis.
   
4. Fertilize monthly with an organic fertilizer such as Down To Earth Rose & Flower Mix 4-8-4 at 5 lbs. per 100 square ft. 
   
5. Pinch out the tips of the main stems three weeks after planting to produce strong, bushy plants.
   
6. Harvest regularly for cut flowers or take off the faded blooms during the summer months to encourage continuous blooming.
   
7. Tall dinner-plate type dahlias will need staking with 6’ bamboo stakes, which should be driven a foot into the ground at planting time. Dahlias can also be added into container gardens with annuals and perennials for a knock-out display of summer color. When planting container gardens with dahlias, make sure to use the Gallery Dahlia Series for best results.
