Ingredients
Nitrogen: Feeds healthy grass growth so your lawn fills in thick and stays green.
Iron citrate: A chelated form of iron that absorbs quickly for rapid deep greening, the kind of green your neighbors will notice.
Potassium and seaweed extract: Helps your lawn handle heat, drought, and everyday stress so it stays strong between applications.
How to use
Apply early morning or evening when your lawn is well hydrated. Avoid use on drought-stressed or heat-stressed lawns.
- Connect the universal sprayer to your hose and the fertilizer pouch. The sprayer is designed for the right mix of water and fertilizer.
- Spray evenly across your lawn until the pouch is empty. This should take about 10 to 15 minutes.
- Once the fertilizer dries, you're good to get back on your grass.
- Reapply every 4 to 6 weeks from spring through fall.
- Keep the sprayer for future applications.
