Growing Cosmos Successfully

For optimal growth, plant cosmos in a sunny location with well-drained soil. Water regularly, aiming for about 1 inch of water per week. Fertilize every 4-6 weeks with a balanced slow-release fertilizer. Prune cosmos plants by cutting back leggy stems to encourage branching. Watch out for common pests such as aphids and caterpillars, using natural pest control methods if necessary. Harvest cosmos blooms regularly to promote continuous flowering and remove any spent flowers to prevent self-seeding.
