Growing Tips

Henry Wilde sunflower thrives in full sun and well-draining, nutrient-rich soil with a slightly acidic to neutral pH (6.0-7.5). Regular watering is important, especially early in the plant's development, but ensure the soil is not waterlogged. Adding compost or organic matter will encourage strong growth​.

When to Grow

Sow sunflower seeds after the last frost when the soil has warmed to at least 60 F. In cooler climates, you can start seeds indoors 2-3 weeks before the last frost. For continuous blooms, consider staggered planting every 2-3 weeks throughout the growing season​. You can check frost dates specific to your region to time this properly.

How to Sow and Plant

Direct sow seeds about 1/2 inch deep, spacing them 18-24 inches apart depending on the desired density. If planting multiple rows, space rows 2-3 feet apart. Keep the seeds moist until they germinate, which typically takes 7-14 days.

How to Grow

Sunflowers are heavy feeders, so mix compost or slow-release fertilizer into the soil before planting. Once the plants reach about 2 feet in height, fertilize lightly again to support their rapid growth. Water deeply but infrequently to promote deep root development. Once established, they are somewhat drought-tolerant, but consistent watering will improve flowering​. Staking may be needed to provide support as they grow.

How to Save

  • When petals die back and heads begin to dry and turn brown, place a paper bag over the heads to protect seeds from birds.
  • After a few days, the heads will dry to a dark brown. Bring the heads indoors and hang them upside down in a dry area in direct sunlight for up to a week, shaking seeds free each day.
  • Store in a cool, dark, dry place.
