Quick plant uptake for rapid green response
Boosting growth after stress or damage

Important Application Guidance

Maximum recommended rate: 1 lb of nitrogen per 1,000 sq ft per application.

1 lb N → 2.17 lbs of product per 1,000 sq ft
0.5 lb N → 1 lb of product per 1,000 sq ft

Water in immediately after application. Urea can volatilize if left on the surface and may cause burn if overapplied.

Not Recommended For

Beginner lawn programs
High-heat summer applications without irrigation
Homeowners unsure of nitrogen math

👉 Use with care—high nitrogen content can burn lawns if overapplied
