Do Sunflowers Need A Lot Of Maintenance

Sunflowers require minimal care. They thrive in well-drained, nutrient-rich soil and typically prefer full sun exposure. Keep the soil evenly moist — not soggy or dry — and weed regularly. Depending on the variety, sunflowers can grow up to a foot per week and need occasional staking or caging to help support their heavy heads from drooping over.

Fertilizing should also be done during early to mid-summer. An all-purpose fertilizer is sufficient for maintaining healthy growth and large blooms for several weeks before harvesting time. When planting multiple seeds, thin out afterward to promote larger individual plants without overcrowding where the competition will occur.

No two sunflower plants are the same, so watch for signs of disease, such as powdery mildew, rust, or botrytis blight, when symptoms appear. More serious diseases require chemical fungicide treatment solutions based on timing and severity; however, there are more natural alternatives other than harsh chemicals that may yield successful results as well (i.e., baking soda).

Overall, sunflowers need virtually no maintenance other than consistent watering, a light amount of fertilizing, light pruning to help extend productivity, and a bit of pest control around nearby leafy plant beds if needed.
