Complete Care Guide
Soil · Water · First 30 days · Monthly care · Troubleshooting · Harvest
Soil
Deep, well-draining, slightly alkaline soil. pH 6.0–7.5. Sunflowers are prairie plants — they want depth for their taproot and they don't care about fertility. Rich soil grows monster giants; lean soil grows more, smaller blooms.
Watering
1 inch per week until flowers form, then taper. Deep, less-frequent watering beats sprinkles — the taproot reaches down for it. Overwatering tall varieties makes them lodge (tip over) in wind.
🗓️ The First 30 Days
- Days 1–7Direct sow 1 inch deep, 6–12 inches apart (closer for branchy types, wider for giants), after last frost. Sunflower seed is big — easy to plant, and easy for birds to steal; cover lightly and water in.
- Days 8–14Keep soil moist through germination (7–10 days). Thin to one plant per spot once true leaves show. Crowded sunflowers grow thin and topple.
- Days 15–21Water deeply weekly. Side-dress lightly if soil is poor. They grow fast — mammoth types gain 6+ feet by midsummer from this humble start.
- Days 22–28Stake giants before they need it; drive a stake 6 inches from the stem early, because a 10-foot sunflower can't be staked after the fact in a storm.
- Days 29–30
