Lesco 50 lb. St. Augustine Weed And Feed with Penoxsulam
The Lesco formulation targets St. Augustine turf with a Penoxsulam-based weed control system. This product is designed to be applied when the turf is wet and to allow drying before encouraging the next growth phase. It provides slow-release feeding that can extend up to eight weeks, supporting steady green-up and root development. The product is noted as safe for Floratam varieties, making it a suitable option for many Southern lawns that rely on St. Augustine grass. Users should follow recommended application windows to maximize weed suppression without stressing the turf.
Lesco 14-0-7 Pre-Emergent Stonewall Fertilizer – 50lbs.
This 50 lb bag blends a pre-emergent herbicide (Prodiamine) with a 14-0-7 NPK formula. The Stonewall pre-emergent provides season-long control for crabgrass and other annual weeds, while the polynomial nitrogen release supports steady growth. The product’s slow-release 30% PolyPlus OPTI45 nitrogen helps maintain soil fertility between applications, reducing the risk of nutrient leaching. It’s well-suited for fans of proactive weed prevention combined with reliable nourishment for resilient turf.
13-0-10 Pre-Emergent Lawn Fertilizer (50 lbs.)
Designed for broad weed prevention with a 13-0-10 NPK ratio, this product emphasizes slow-release nitrogen for ongoing growth and color. It’s suitable for all grass types and recommends two applications on cool-season lawns in spring and one application in fall for warm-season lawns. The pre-emergent component aims to prevent crabgrass and other annuals from taking hold, helping homeowners maintain a dense, even lawn through critical growth periods.
Lesco Fertilizer Plus Herbicide, Weed And Feed, 18-2-3
This dual-action product combines fertilizer with herbicide to feed the lawn while targeting broadleaf weeds. The 18-2-3 NPK ratio supports vigorous growth while 30% PolyPlus OPTI45 slow-release nitrogen sustains color and density across multiple weeks. The weed control component is tuned to curb common broadleaf weeds without excessive stress to the turf, making it a practical choice for active lawns facing seasonal weed pressure.
Lesco 19-0-6 Dimension Pre-Emergent Fertilizer – 50 lb
Dimension-based pre-emergent weed control is the cornerstone of this 50 lb bag, designed to prevent crabgrass and other weeds before germination. The 19-0-6 NPK ratio supports vibrant green growth, with potassium aiding stress tolerance and root development. The 30% PolyPlus OPTI45 coated nitrogen ensures slow, steady feeding to minimize nutrient loss and deliver consistent turf performance throughout the season.
Buying Guide
- Weed control approach: Decide between pre-emergent protection (prevents weed seeds from germinating) and post-emergent control (targets existing weeds). Several products in this 50 lb category blend both goals at different strengths.
- Grass compatibility: Some formulas are tuned for St. Augustine or Bermudagrass, while others are suitable for all grass types. Choose a product aligned with your lawn variety to maximize effectiveness and avoid turf stress.
- NPK balance and release: Look for balanced nitrogen content and slow-release nutrients (e.g., PolyPlus OPTI45). Slow-release formulations reduce nutrient runoff and provide steady feeding over weeks.
- Timing and seasonal strategy: Cool-season lawns may benefit from spring and fall applications, while warm-season lawns often require fewer mid-season applications. Follow label guidance for best results.
- Application conditions: Some products advise application when turf is wet or dry, or require irrigation afterward. Adhering to specific conditions helps maximize weed control and minimize turf damage.
- Safety and variety considerations: If you have Floratam or other specific grass varieties, verify compatibility to ensure safe use and avoid unintended damage to lawn health.
- Environmental considerations: Choose formulations with slow-release nitrogen to minimize leaching and protect waterways, while still delivering effective weed suppression.
When selecting a 50 lb weed and feed product, consider your grass type, typical weed pressures, local climate, and maintenance schedule. Combining reliable weed prevention with steady nutrition supports a healthier, more resilient lawn across seasons.
