Dahlias
Asteraceae family - Perennial
Dahlias are late-season flowers that bloom from midsummer through the first frost, offering a vast variety of colors, patterns, sizes, and flower forms. Dahlias are perennials in warmer climates and considered annuals below USDA hardiness zone 8. These flowers grow best in full sunlight with well-drained soil.
Light
In order to produce abundant blooms, dahlias require full sun, preferably 6 to 8 hours a day. In climates similar to their native growing regions (USDA hardiness zones 8 and up), this plant will benefit from shade mid afternoon when the sun is especially hot.
How to care for Dahlias:
- Plant dahlia tubers outdoors in the early spring, after the last frost and once the soil has warmed. Depending on the variety, plant dahlia tubers 2 to 6 inches deep.
- Choose a planting location that receives full sunlight.Place smaller varieties at least 12 inches apart and larger varieties up to 3 feet apart to allow for air circulation.
- After the tubers have sprouted, water the plants at least once per week, increasing waterings to twice per week or more during dry spells.
