Preen Garden Weed Preventer Plus Plant Food 31.3 lb Bag — Covers 5,000 sq ft, 2-in-1 Preemergent & Fertilizer

Preen Garden Weed Preventer Plus Plant Food is a granular 2-in-1 product that prevents weed seeds from sprouting while feeding established plants for up to three months per application.

Designed for beds, borders, ground covers, trees and shrubs, this 31.3 lb bag treats up to 5,000 square feet and combines preemergent weed control with balanced all-purpose fertilizer. The granular formula is easy to apply by hand or as a refill for compatible applicators; after watering in, it forms a protective zone at the soil surface to keep weed seedlings from taking hold while supplying nutrients to support blooms and root development.

How does this product stop weeds without harming my garden plants?

The formulation acts as a preemergent: it inhibits germinating weed seeds near the soil surface before they become visible weeds, while being safe for established plants listed on the product label. It is intended for use around a wide range of flowers, vegetables, trees and shrubs once they are established.

• Creates a barrier at the soil surface to block weed seed germination.
• Safe around 200+ labeled plant varieties when used as directed.
• Prevents weeds for up to three months per application.
• Must be applied to bare soil and activated with thorough watering.

When and how should I apply it for best results?

Apply anytime during the active growing seasons—spring, summer or fall—after removing visible weeds. Even distribution and prompt watering are key: spread evenly over the target area, then water deeply to move granules into position where they form the protective layer.

• Remove existing weeds before application for best performance.
• Spread by hand or refill compatible flip-top applicators and drums.
• Water thoroughly after spreading to activate the product.
• One application protects and feeds for about three months.

How much area does one bag cover and how long does it last?

One 31.3 lb bag covers approximately 5,000 square feet, making it suitable for medium to large landscapes. Coverage plus the three-month window per application means fewer seasonal treatments and less time spent maintaining beds.

• Coverage: roughly 5,000 sq. ft. per 31.3 lb bag.
• Duration: up to 3 months of weed prevention and continual feeding.
• Economical for larger properties and repeat seasonal use.
• Bag dimensions facilitate storage in sheds or garages.

Can I use it with my existing planting and watering routine?

Yes—this product complements routine watering and established plant care when used according to label directions. It’s formulated to fit into typical landscape maintenance schedules, and may be applied by hand or with refillable applicators for targeted distribution.

• Works with normal irrigation—water in after application.
• Use around established plantings listed on the label.
• Compatible with standard garden maintenance timing.
• Available in a refillable bag size for cost-effective coverage.
