How to Grow Purple Sunflowers
Growing purple sunflowers is similar to growing traditional sunflowers.
Here’s a step-by-step guide:
1. Choosing the Right Location
Purple sunflowers need:
- Full sun (6-8 hours of direct sunlight daily)
- Well-draining soil
- Protection from strong winds
2. Preparing the Soil
- Test your soil pH – aim for 6.0 to 7.5
- Add compost or well-rotted manure to improve soil quality

3. Planting
- Plant seeds directly in the garden after the last frost date
- Sow seeds 1 inch deep and 6 inches apart
- Thin seedlings to 1-2 feet apart when they reach 6 inches tall
4. Watering
- Water deeply but infrequently to encourage deep root growth
- Provide about 1 inch of water per week
- Increase watering during dry spells or extreme heat
5. Fertilizing
- Apply a balanced, slow-release fertilizer at planting time
- Avoid high-nitrogen fertilizers, which can reduce flowering
- Side-dress with compost mid-season for an extra boost
6. Supporting Your Sunflowers
Some purple sunflower varieties can grow quite tall.
To support them:
- Use stakes or bamboo poles
- Tie stems loosely to supports with soft twine
- Place supports when plants are young to avoid root damage
