Description
The Dahlia is a lush, flowering tuberous perennial that blooms from July until the first frost in a wide array of colors and flower forms. It produces excellent cut flowers and thrives in sunny beds. The tubers are not winter-hardy.
Care instructions
Plant the tubers in mid‑May (after the ice‑holy days, week 20) in a full‑sun location with nutrient‑rich soil. Water deeply during dry periods and support tall varieties with a stake. Regularly prune spent blooms to encourage continuous flowering. After the first frost in October, dig up the tubers, keep them dry and frost‑free over winter, and re‑plant in spring.
