Plant Care Guide: Sunflower – Giant Single
Sunflower ‘Giant Single’ is a towering variety known for its large, bright yellow blooms that attract pollinators and provide seeds for birds and humans alike. It thrives in warm, sunny conditions and is a great addition to vegetable gardens, borders, or as a striking feature plant.
Planting
- Best Time to Plant: Sow seeds in late spring to early summer when temperatures are consistently above 15°C.
- Soil Preparation: Prefers well-drained, fertile soil with a pH of 6.0-7.5, enriched with compost.
- Spacing: Sow seeds 2-3 cm deep and 30-60 cm apart to allow for strong root development.
- Sunlight: Requires full sun for optimal growth.
- Watering: Water deeply but infrequently, allowing soil to dry slightly between waterings.
Care & Maintenance
- Support: Tall plants may require staking to prevent wind damage.
- Fertilising: Apply a balanced fertiliser at planting and side-dress with compost as needed.
- Weeding: Keep the area weed-free to prevent competition for nutrients.
- Mulching: Use mulch to retain moisture and suppress weeds.
Pests & Diseases
- Common Pests: Aphids and birds may target seedlings and seeds. Use netting or companion planting to deter them.
- Common Diseases: Fungal issues such as mildew can occur in humid conditions. Ensure good airflow and avoid overhead watering.
Companion Planting
- Good Companions: Corn, beans, and pumpkins create a beneficial growing environment.
- Avoid Planting Near: Potatoes, as they can compete for nutrients and space.
Harvesting
- When to Harvest: Ready in 80-100 days when flower heads droop, and seeds turn brown.
- How to Harvest: Cut flower heads and allow seeds to dry before removing.
- Storage: Store dried seeds in a cool, dry place for later use or replanting.
Bonus Tip
Leave a few mature flower heads in the garden to attract birds and encourage natural reseeding for the next season.
Happy gardening! 🌻
