How To Make White Sunflowers Bloom

1. Light

White sunflowers, like their yellow counterparts, thrive in full sunlight. Ensure they receive at least 6 to 8 hours of direct sunlight daily. Plant them in a location where they can bask in the sun’s warmth, and watch as their blooms reach for the sky.

2. Soil

Sunflowers prefer well-draining soil. Ensure the soil is rich in organic matter, providing essential nutrients for healthy growth. Consider adding compost or well-rotted manure to enhance soil fertility.

3. Water

While sunflowers are relatively drought-tolerant, but consistent watering is still crucial, especially during dry periods. Water the plants at the base to prevent moisture on the leaves, which can lead to fungal issues. Aim for deep, infrequent watering rather than shallow and frequent.
