Pests or Diseases: tolorates deer, heat & humidity, rabbits
Easy to Grow: 1. Dig a hole 3-4" deep.
2. Set each tuberous root firmly in place.
3. Cover each tuberous root with soil and water thoroughly.
Planting Instructions: Plant Dahlias in well-drained soil in a sunny location. Supply ample moisture and fertilizer during the growing season. When the plant reaches 1-1/2' in height, trim entire plant to 1'. In about two weeks trim the plant again back to about 1-1/2'. This will encourage your Dahlia to produce an abundance of flowers. Remove all spent flowers.
Container Planting: Containers are excellent when used as an ornamental feature, a planting option when there is little or no soil to plant in, or for plants that require a soil type not found in the garden or when soil drainage in the garden is inferior. If growing more than one plant in a container, make sure that all have similar cultural requirements. Choose a container that is deep and large enough to allow root development and growth as well as proportional balance between the fully developed plant and the container. Plant large containers in the place you intend them to stay. All containers should have drainage holes. A mesh screen, broken clay pot pieces(crock) or a paper coffee filter placed over the hole will keep soil from washing out. The potting soil you select should be an appropriate mix for the plants you have chosen. Quality soils (or soil-less medias) absorb moisture readily and evenly when wet. If water runs off soil upon initial wetting, this is an indicator that your soil may not be as good as you think.
Prior to filling a container with soil, wet potting soil in the bag or place in a tub or wheelbarrow so that it is evenly moist. Fill container about halfway full or to a level that will allow plants, when planted, to be just below the rim of the pot. Tuberous root should be level with soil line when project is complete. Water well.
To plant container-grown plants, prepare planting holes with appropriate depth and space between. Water the plant thoroughly and let the excess water drain before carefully removing from the container. Carefully loosen the root ball and place the plant in the hole, working soil around the roots as you fill. If the plant is extremely root bound, separate roots with fingers. A few slits made with a pocket knife are okay, but should be kept to a minimum. Continue filling in soil and water thoroughly, protecting from direct sun until stable.
When to Plant Outdoors: Plant in spring, after the ground warms to about 50º F.
