Description

The tuberous Dahlia blooms from July until the first frost in a wide range of shapes and colors, making it one of the most reliable cut flowers in the farmer's garden. It grows from overwintered tubers and provides a steady supply of blooms for the vase over many months.

Care instructions

Pre‑treat the tubers in mid‑April in a frost‑free area and plant them after the last frost (mid‑May, week 20) in a sunny spot with nutrient‑rich soil. Water regularly and deeply, especially during heat periods, and consistently remove spent flowers to encourage prolonged blooming. After the first frost in October, dig up the tubers, store them frost‑free and dry for overwintering.

Companion planting

Good neighbors

carrot family (Apiaceae)

Calendula and Tagetes next to carrots keep the carrot fly away with their scent.

Rather not

nightshade family (Solanaceae)

Sunflowers release substances into the soil that inhibit potato tuber growth, and they also compete for water and nutrients.
