How to care for Cosmos bipinnatus Rubinato:
Easy to grow, Cosmos enjoy reliably moist soil but be careful not to overwater. Pinch out young tips for a bushier plant. Deadhead spent flowers regularly to stimulate further blooms. May require staking with peas sticks or brash in exposed locations.
Sowing instructions:
In early spring, sow seed shallowly in seed trays and keep under glass, transplanting them into individual pots when large enough to handle. Harden off before planting outside after the frosts. Alternatively, sow in-situ in mid- to late spring in a well-prepared bed and thin the seedlings out as they grow to allow approximately 30cm between each.
