Growing Duet

Plant tubers in full sun once soil has warmed. Stake early, as stems reach chest height and need support before they lean. Pinch the central shoot after the third set of leaves to encourage branching and a larger harvest of side stems. Water deeply and consistently, but let the top inch of soil dry between sessions to discourage rot. Feed with a low-nitrogen fertilizer once buds begin to show. Deadhead spent blooms regularly to keep new ones coming. Lift tubers after the first frost, allow them to dry briefly, and store in a cool, frost-free location through winter.

Spacing: Space roughly 2–3 ft apart
Staking: Stake early — stems carry heavy blooms and lean in wind
