How to Care for Cosmos

Water deeply once a week, and allow the soil to dry out between waterings. Overwatering can cause damage to your Cosmos roots. They also benefit from deadheading as soon as your flowers die. In climates warm enough for Cosmos to grow as perennials, they should be mulched heavily in winter months. Cosmos grown in containers should be brought indoors during the winter.
