Cosmos are annuals that bloom throughout Spring, Summer, and into Fall. They like full sun and attract butterflies. Prune or deadhead old blooms to keep cosmos blooming all season. For beginner gardeners, Cosmos are very easy to grow. Full sun is the key. Every few weeks, fertilize with an organic fertilizer such as Espoma PT4 4-Pound Plant-Tone Organic 5-3-3 Plant Food.
Check your local Home Depot, Lowes or online Burpee Gardening for their selection of Cosmos! To learn more about pruning, watch our How to Prune playlist on YouTube! To learn how to plant, fertilize and prune your way to a gorgeous garden, subscribe to our YouTube channel!
