Caring for Your White Sunflowers
Watering
White sunflowers need regular watering, especially during dry spells. Water deeply once a week, or more often if the weather is particularly hot and dry.
Fertilizing
Fertilize your sunflowers once a month with a balanced, all-purpose fertilizer. Avoid over-fertilizing, as this can lead to weak stems.
Pest Control
Watch out for common pests like aphids and sunflower moths. Use organic pest control methods when possible to protect beneficial insects.
Harvesting White Sunflowers
For Seeds
If you want to harvest seeds, wait until the back of the flower head turns brown. Cut the head off with about 12 inches of stem attached and hang it upside down in a dry, well-ventilated area.
For Cut Flowers
Cut white sunflowers in the morning when they’re just beginning to open. Place them immediately in water for the longest vase life.
