Aster Seeds

Asters are a gorgeous staple for cut flower gardens, known for their daisy-like blooms that add color, texture, and charm to late-summer arrangements. These resilient plants thrive in the Canadian climate and attract bees, butterflies, and other pollinators to your garden. Asters are perfect for garden borders, flower beds, and seasonal bouquets.

How do I grow Asters from seed?

In order to grow Asters from seed, you need to start seeds indoors 6–8 weeks before the last frost or sow them directly outdoors after danger of frost has passed. Use well-drained soil in a sunny spot, and lightly cover the seeds with soil, keeping them moist until germination. Thin seedlings to provide airflow and prevent mildew. For continuous blooms, deadhead regularly and water consistently. Asters flourish when given plenty of sun and space to branch out, rewarding you with vibrant, long-lasting flowers through fall.
