Growing velvet queen sunflowers (Helianthus annuus ‘Velvet Queen’) is a rewarding experience that brings beauty and cheer to any garden. These majestic plants, with their velvety-black petals and towering stalks, are not only visually stunning but also attract pollinators and provide a source of food for birds. If you’re looking to add these captivating blooms to your outdoor space, follow our comprehensive guide on how to plant velvet queen sunflower seeds.
Selecting the Right Location
Velvet queen sunflowers thrive in full sun and well-drained soil. Choose a spot in your garden that receives at least six hours of direct sunlight per day. The soil should be loose, fertile, and have a pH between 6.0 and 7.5.
Preparing the Soil
Before planting, prepare the soil by tilling it to a depth of 12 inches. Amend the soil with organic matter, such as compost or manure, to improve its structure and fertility. If your soil is heavy or compacted, consider adding sand or perlite to improve drainage.
Planting the Seeds
Plant velvet queen sunflower seeds in early spring after the last frost date has passed. Sow the seeds 1 inch deep and 6-12 inches apart. Cover the seeds with soil and gently press down to ensure good soil contact. Water the seeds thoroughly and keep the soil moist until germination occurs.
Germination and Seedling Care
Germination typically takes 7-14 days. Once the seedlings emerge, thin them out to the strongest one per planting hole. Water the seedlings regularly, especially during hot and dry weather. Fertilize the seedlings every few weeks with a balanced fertilizer to promote healthy growth.
Staking and Support
As the sunflowers grow taller, they may need staking to prevent them from toppling over. Place stakes next to the plants and gently tie the stems to the stakes using soft twine or plant ties. This will provide support and keep the plants upright.
Mulching and Weed Control
Mulch around the sunflowers with organic matter, such as straw or wood chips, to retain moisture, suppress weeds, and regulate soil temperature. Keep the area around the plants free of weeds, as they can compete for nutrients and water.
Bloom Time and Pollination
Velvet queen sunflowers typically bloom in mid to late summer. The large, velvety-black flower heads are a magnet for pollinators, including bees, butterflies, and birds. These pollinators are essential for seed production, so avoid using insecticides that could harm them.
Harvesting Seeds
If you wish to save seeds for future planting, allow the flower heads to dry on the plants. Once the heads are fully dry, cut them off and place them in a paper bag. Store the seeds in a cool, dry place until you’re ready to plant them.
Tips for Success
- Start seeds indoors 4-6 weeks before the last frost date for earlier blooms.
- Protect seedlings from slugs and snails by using slug bait or creating a barrier around the plants.
- Water sunflowers deeply and regularly, especially during hot and dry weather.
- Deadhead spent blooms to encourage new flower production.
- Cut back the plants in the fall after they have finished blooming.
