In the June subscriber edition, you'll receive a free double-pack of seeds for cornflower 'Blue Ball' and zinnia 'Early Wonder', along with valuable information on growing pollinator-friendly wildflowers. But let's focus on the zinnias, ideal for adding eye-popping colour to your garden or pot displays.
- Choosing the Right Time to Sow Plant zinnia seeds outdoors 1 to 2 weeks after your area’s average last frost date when the soil has warmed. If starting indoors, sow seeds 4 to 6 weeks before your last frost date and transplant seedlings after frost has passed.
- Preparing the Soil and Location Zinnias thrive in full sun and well-draining soil that is moderately fertile. They prefer soil that is not too rich to avoid excessive foliage at the expense of flowers.
- Seed Planting Sow seeds about 1/4 inch deep. Plant seeds in groups, spacing groups about 12 inches apart. Each group should have about 3 seeds to increase chances of germination. Water using a small watering can with a rose, so the seeds are not dislodged.
- Germination and Thinning Seeds typically emerge in 3–10 days. When seedlings reach about 2 inches tall, thin them to one strong plant per 12-inch space to give ample room for growth.
- Watering and Care Keep the soil evenly moist but avoid waterlogging. Once established, zinnias are relatively drought tolerant, but consistent watering encourages better blooms.
- Maintenance Deadhead spent flowers regularly to promote continuous blooming throughout the summer and into fall until frost. Zinnias are heat tolerant and attract pollinators like hummingbirds.
- Additional Tips
- Zinnias grow well in containers or garden beds.
- They can grow to about 24 inches tall and 12 inches wide depending on variety.
- Avoid starting seeds too early indoors as they do not benefit much from early sowing.
This simple routine will help beginners grow vibrant, long-lasting zinnia blooms in their gardens with ease. The June extras contain inspirational features, practical projects, and a full zinnia Grow Guide, along with more varieties to try. Happy gardening!
