Whether you seek vibrant colors, unique shapes, or captivating textures, ornamental sunflowers offer a delightful array of options. This comprehensive guide will take you through the essential steps of growing ornamental sunflowers, ensuring a flourishing and radiant display in your garden.
1. Choosing the Right Variety
The first step in growing ornamental sunflowers is selecting the appropriate variety. With numerous cultivars available, consider factors such as height, bloom size, color, and petal shape. Some popular varieties include:
- ‘Autumn Beauty’: Double-flowered blooms in rich shades of orange and red.
- ‘Chianti’: Striking double-flowered variety with burgundy-red blooms.
- ‘Evening Sun’: Golden-yellow blooms with a dark center.
- ‘Moulin Rouge’: Double-flowered blooms with deep red petals.
- ‘Ring of Fire’: Bicolor blooms with yellow petals and a red ring around the center.
2. Preparing the Soil
Ornamental sunflowers thrive in well-drained, fertile soil with a pH between 6.0 and 7.5. Amend the soil with compost or well-rotted manure to improve its structure and fertility. Sunflowers require plenty of sunlight, so choose a location that receives at least six hours of direct sunlight per day.
3. Planting Ornamental Sunflowers
Sow the ornamental sunflower seeds directly in the garden in the spring after the last frost. Space the seeds 12-18 inches apart and cover them with 1/2 inch of soil. Water the seeds thoroughly. You can also start the seeds indoors 4-6 weeks before the last frost. Transplant the seedlings into the garden when they are 2-3 inches tall.
4. Watering and Fertilizing
Water ornamental sunflowers regularly, especially during hot and dry weather. Aim to provide 1-2 inches of water per week. Fertilize the plants every few weeks with a balanced fertilizer. Follow the instructions on the fertilizer package for the appropriate application rate.
5. Pinching and Deadheading
Pinching the tips of the main stem when the plants are 6-8 inches tall encourages branching and more blooms. Deadhead the spent blooms to promote continuous flowering and prevent the plant from putting energy into seed production.
6. Pests and Diseases
Ornamental sunflowers are generally resistant to pests and diseases, but they can be affected by aphids, spider mites, and powdery mildew. Monitor the plants regularly for signs of pests or diseases and take appropriate action if necessary.
7. Harvesting Ornamental Sunflowers
Ornamental sunflowers are ready to harvest when the blooms are fully open and the petals begin to droop. Cut the stems at a slant to prevent water from collecting in the stem and causing rot. Hang the sunflowers upside down in a cool, dry place to dry.
