About this plant
Zinnia produces colorful flowers on upright stems and makes a welcoming first flower crop. Grow it as a warm-season annual in all four zone groups (3-4, 5-6, 7-8, 9-10), with full sun.
Choose well-draining soil and provide regular watering at soil level. Leave space between plants so air can move through the foliage, and remove spent blooms as they fade.
Common beginner failures and fixes
- Leaves frequently wetted during watering: Direct water onto the soil beneath the plant.
- Crowded growth with poor airflow: Follow the variety's spacing guidance and thin crowded seedlings.
- Weak stems in shade: Choose a full-sun location.
- Faded flowers accumulating: Cut off spent blooms above a healthy leaf junction.
Beginner checklist
- Grow as a warm-season annual in your zone group.
- Select a full-sun site.
- Prepare well-draining soil.
- Water regularly at soil level.
- Space plants for airflow and remove faded blooms.
Zone groups and planting windows here are general guidance. Confirm your own zone and last frost date locally before planting.
