Grass Powerhouse Liquid Fertilizer (2-pack)

Most lawns show visible green-up within 24 to 48 hours. Full results within a week, faster if your lawn is already well-hydrated and actively growing.

Liquid fertilizer like Grass Powerhouse absorbs fast and delivers results quickly, making it ideal for green-up and growth boosts throughout the season. Granular fertilizer releases more slowly and is better for long-term soil building. Many customers use both. Liquid for fast results between applications, granular for steady season-long feeding.

Spring through fall when your grass is actively growing and temperatures are between 50 and 85°F. Early morning or evening on a dry lawn is best. Skip applications during drought conditions or when your lawn is heat-stressed.

Light rain 24 hours after applying is fine and helps nutrients absorb into the soil. Avoid applying if heavy rain is expected within 4 hours. Don't apply to a waterlogged or soaking wet lawn.

Yes, applying too often or to stressed grass can cause burning. Stick to every 4 to 6 weeks and skip applications when your lawn is heat-stressed or drought-stressed. When in doubt, water first and wait a few days before applying.

Let the fertilizer dry fully, about 1 to 2 hours, before applying anything else. For weed control, wait 24 hours after it dries. For seeding, apply fertilizer first and seed once dry, or wait until new grass has been mowed at least once before fertilizing again.

Once fully dry, your lawn’s safe for kids, pets, and bare feet. On a warm sunny day that's typically 1 to 2 hours. Give it a bit longer if it's cool or humid.
