LESCO 13-0-5 Stonewall Pre-Emergent 0.43% Plus Fertilizer

An inviting green lawn is a thing of beauty, but it is no simple task to perfect. LESCO 13-0-5 Stonewall Pre-Emergent 0.43% Plus Fertilizer is a combination pre-and post-emergent product that can be used on warm- and cool-season grasses to help keep lawns healthy and vibrant all season long. 

Not only does this product prevent weeds before they germinate, it also feeds your lawn with essential nutrients that help promote stronger, greener grass. ESD, including biosolids, iron, nitrogen, and potassium, LESCO 13-0-5 is long-lasting for extended lawn health and reduces the potential for nutrient loss.

Active Ingredients

The active ingredient, phenylenediamine (0.43%), functions as a pre-emergent herbicide, preventing the growth of troublesome weeds before they take root. This is especially good for managing invasive weeds that can crowd out the desirable turfgrass. Apply LESCO Stonewall as directed to effectively minimize annual grassy weeds such as crabgrass, as well as broadleaf weed populations.

Compatible Lawn Types

LESCO Stonewall Pre-Emergent Plus Fertilizer is labeled for use on an expansive range of turfgrass species, making it a one-size-fits-all solution for homeowners, landscapers, and turf professionals. It is effective on:

• Tall Fescue – a durable and robust cool-season grass with deep roots
• Bermudagrass – A warm-season grass with excellent drought tolerance
• Zoysiagrass – Tough, slow-growing turf grass of high quality
• St. Augustinegrass – A shade-loving grass for the South
• Kentucky Bluegrass – This well-loved cool-weather grass has a dense, carpet-like look
• Ryegrass - A fast-growing grass that gives lawns a nice greenish color

By catering to multiple grass varieties, LESCO 13-0-5 provides flexibility for various lawn care needs across different climate zones.

Key Features

The perfect combination of weed control and natural lawn food that results in a thick, green lawn. LESCO 13-0-5 Stonewall Pre-Emergent 0.43% Plus Fertilizer helps prevent weed growth, and provides balanced nutrition to keep your turf healthy and resilient.

Made with exclusive, all-in-one, water-smart, proprietary coating technology, it promotes early grass establishment and greening in 6 days, and has a large particle size, so it's easy to use and apply.

1. Pre-Emergent Weed Control for a Weed-Free Lawn

The pre-emergent herbicide doesn’t let the weeds grow back up, so you can also have a weed-free lawn. Post-emergent products, such as traditional herbicides, only do half the job — they will only kill whatever’s there. LESCO Stonewall arrests weeds before they start, helping to significantly reduce hand-weeding or post-application herbicide sprays.

2. Balanced Fertilization with 13-0-5 Nutrient Ratio

The 13-0-5 mix provides key nutrients necessary for quality turf growth, such as:

• 13% Nitrogen (N) – Patented stabilizer that allows for direct to plant di-gestion, feeding the lawn for rapid lush green growth and quick dark green color for your best looking lawn
• 0% Phosphorus (P) – Ideal for mature lawns that don’t require phosphorus for root development
• 5% Potassium (K) – Better disease resistance, ability to withstand drought, and better overall plant health

This will provide slow feeding, steady nutrition to all plants of your lawn throughout the growing season.

3. Biosolids for Sustainable Nutrient Release

What makes LESCO 13-0-5 Stonewall unique is that it is made up of biosolid, which helps improve soil health through:

• Long-lasting, slow-release formula promotes healthier turf that remains greener longer
• By improving soil structure and increasing water-holding capacity and microbial activity
• It’s environmentally friendly because you can dramatically cut down on nutrient runoff.

Biosolids add organic matter to the soil, which increases its capacity to hold nutrients and water, making conditions favourable for the growth of turf.

4. Iron for a Deep Green Lawn

Iron is an essential micronutrient that plays a key role in chlorophyll production, which is responsible for the green color of plants. LESCO Stonewall contains added iron to:

• Prevent iron deficiency (chlorosis), which can cause yellowing in grass
• Ensure optimal photosynthesis for healthy, dense turf
• Improve the aesthetic appeal of the lawn with a rich, vibrant green color

5. Extended Nutrient Release with PolyPlus OPTI45

It includes 30 percent PolyPlus OPTI45, or controlled-release nitrogen technology, which means that nutrients are available throughout a period of time. This would limit the loss of nutrients by leaching and keep a steady amount of nitrogen around instead of requiring repeated applications.

6. Effective Year-Round Application

It can also be used in spring and fall to maintain a clear lawn with good health, so it’s a versatile addition to your seasonal lawn care program. The spring-time application can be used as a way to keep summer weeds in check before they start, and applying in the fall will work to shore up the lawn as it heads into the colder months.

7. Long Waiting Period for Seeding (90-120 Days)

There's a pre-emergent herbicide in this product, so you need to wait 90 -120 days to seed or plant. This gives the herbicide a chance for decomposition before the new seed arrives. For those planning to seed a new lawn, it’s essential to get this fertilizer down early enough in the season for the pre-emergent to break down.

8. Easy-to-Use Granular Delivery System

LESCO Stonewall is a weighty granule product and easy to spread with a spreader, providing uniform application and coverage for your yards. Granules offer:

• Uniform fertilizer and herbicide application
• Less drift than with liquid herbicides
• Slow feeding, for healthy lawns all season long

Application Instructions

For the best results, here’s how you should apply it:

1. Measure Up Your Lawn Space – Work out the square footage to establish how much product you need.
2. Calibrate Your Spreader – Calibrate your spreader per the manufacturer’s recommendations.
3. Spread evenly - Walk evenly while spreading the granules along the lawn.
4. Water After Applying – Light watering aids in activating the herbicide and actually helps it penetrate the soil.

Safety Precautions

• Keep out of reach of children and pets.
• Keep in a cool, dry place that is free of moisture.
• Use according to all label directions for best results.
