Keep the soil consistently moist until seedlings emerge, which typically takes 7-14 days. Once seedlings are a few inches tall, thin them to stand 9-12 inches apart to allow good air circulation.

Water regularly, aiming for about an inch of water per week, and mulch to retain moisture. Deadhead spent flowers to encourage continued blooming. Zinnias are relatively pest-free and thrive in warm weather, making them a low-maintenance choice for any sunny garden.
