A healthy, weed-free lawn is the star of a well-kept yard – and keeping it in such great condition means using high-quality fertilizers and weed control.

In this article, we’re taking a look at Lesco fertilizer and weed control, as well as talking about how and when to apply these products for the best results.

What is Weed and Feed Fertilizer?

What is Lesco Weed and Feed Fertilizer?

A weed and feed fertilizer is a product that combines essential plant nutrients with herbicides that kill emerging weeds. The best lawn fertilizers contain a combination of nitrogen, phosphorus and potassium, and are usually high in nitrogen.

If you want a good fertilizer for spring that will also kill weeds before they start growing, look for a 18-0-9, 18-0-4 or 17-0-7 Lesco lawn fertilizer that contains a pre-emergent herbicide

What Do Fertilizer Numbers Mean?

The numbers on a fertilizer product refer to the ratio of nitrogen, phosphorus and potassium in the fertilizer. This is important because some plants (like grass) require more nitrogen, while others (like fruit trees) prefer more potassium. 

An 18-0-9 fertilizer, for example, is 18% nitrogen, 0% phosphorus and 9% potassium. High nitrogen formulas are ideal for plants that need a lot of green leaf growth, helping to develop lush green lawns that grow densely and vigorously.

How Does Weed and Feed Fertilizer Work?

Weed and feed fertilizer works by killing off common, leafy lawn weeds like dollarweed and dandelions. You get two types:

Pre-Emergent Weed and Feed

Pre-emergent weed and feed products kill off weeds before they have a chance to grow and develop leaves. This won’t kill your grass or existing weeds, but it will kill any seeds waiting to sprout in your soil.

Post-Emergent Weed and Feed

The herbicide granules are absorbed by the leaves of existing, growing weeds, which then kills the weed. It shouldn’t harm your grass unless you put too much on, so be sure to follow the instructions on the product.

Depending on the condition of your lawn, you may use one type or both, using pre-emergent in early spring and post-emergent in summer.

Lesco Weed and Feed Fertilizer

Lesco fertilizers and weed and feed products are tried and tested, so you know you can rely on them for good results. Built on over 50 years of expertise, these products are tailored to different grass varieties, weed control issues and more in order to deliver the lush, healthy lawn you want this summer!  

Another good thing about Lesco is that they have included the MSDS sheets, which show the chemical breakdown of the product. There are also instructions on how you can properly store the product and tips on how you can avoid exposing yourself to harmful chemicals.

How Much Fertilizer Should I Buy?

Generally speaking, a 50lb bag of fertilizer will cover about 12,500 square feet of lawn. It’s best to use a fertilizer spreader if you want to get the most even spread of fertilizer and the resulting growth over your lawn.

When is the Best Time to Apply Lesco Weed and Feed Fertilizer?

When is the Best Time to Apply Lesco Fertilizer Weed and Feed?

When it comes to fertilizing your lawn, timing is everything. It’s best to wait for spring when the soil temperature (not the air temperature) has reached 55 degrees Fahrenheit for at least 5 days, usually in mid-April.

It is at this temperature when lilacs begin to blossom – or you can use a soil thermometer or USDA's CRN/SCAN Soil Map to time yourself perfectly.

This is also the time when weeds start to sprout, so it’s best to apply a pre-emergent weed and feed.

How to Apply Lesco Fertilizer to Your Lawn

Before applying fertilizer or weed and feed, clear away any winder debris from your lawn, read through the product instructions, aerate and water your lawn well to help absorption.

Choose a day where it is unlikely to rain for 48 hours following application. You can apply garden fertilizer two different ways:

  • By hand – Wear gloves and walk backwards, throwing handfuls of fertilizer in an even, sweeping motion over your plants and lawn.
  • By broadcast applicator – You can purchase a fertilizer spreader or broadcast applicator which drops fertilizer evenly as you walk it through the garden over your lawn.

    This works well on even surfaces and is ideal if you have a large yard, but you will still have to apply the fertilizer by hand to the beds and hard-to-reach areas.

Lesco Weed and Feed Fertilizer Schedule

Setting Up a Lesco Fertilizer Schedule

Warm season varieties of grass like St Augustine, Bermuda, Buffalo, Centipede and Zoysia grass should be fertilized twice in the spring and twice again during the fall season.

In the spring, you need to apply the first dose of fertilizer (a pre-emergent weed and feed) once the new grass starts growing and the second dose should be applied 30 days after this.

The second dose can be a post-emergent weed and feed if you have a problem with growing weeds.

In the fall, the first dose of fertilizer should be applied in early fall while the grass is still growing and the weather is warm, with the second dose occurring 30 days after this.

This should be a fertilizer or post-emergent weed and feed depending on the condition of your lawn.

Cool season grass varieties, like Kentucky bluegrass, creeping bent grass, annual and perennial ryegrass, tall fescue and creeping red fescue, can be fertilized with a pre-emergent weed and feed once during the spring season.

As the new growth starts, and twice during the fall season 30 days apart with a fertilizer or post-emergent weed and feed when the temperature starts to cool down.

What is the Best Lesco Lawn Fertilizer to Use in Spring?

We recommend a pre-emergent Lesco weed and feed fertilizer, as this will kill off any seeds and newly-sprouting weeds while feeding your grass well as it enters its high-growth phase.

How to Safely Store Lesco Fertilizers

It’s important to store your Lesco fertilizers properly to keep it viable and safe. Here are some useful tips for storing granular fertilizer:

  1. Keep away from any moisture
  2. Do not put in an airtight container or bag as the gasses can build up
  3. Keep away from any flammable materials and heat, including direct sunshine
  4. Choose a well-ventilated, dry, cool space or raise off the ground on a shelf
  5. Do not mix fertilizers with other fertilizers or other products
  6. Store out of reach of pets and children

For liquid Lesco fertilizers, ensure the cap is secure and the bottle is stored in a dry, cool space out of the sunlight and away from heat, pets and children.

Fertilizer Safety Tips

Lesco fertilizer is a concentrated chemical mix, so it’s important to take basic safety precautions

Fertilizer is a concentrated chemical mix, so it’s important to take basic safety precautions. This is especially important if you are using a weed and feed fertilizer, due to the harmful herbicide content.

  • Wear gloves – The concentrated nitrogen in fertilizer can burn the skin.
  • Wear eye protection – Granular fertilizer contains fine particles that get into the air and can harm your eyes. If you don’t have safety glasses, wear sunglasses or goggles.
  • Cover your mouth – A mask or a scarf over your mouth will prevent you from breathing in any loose particles in the air.
  • Clean up – Any excess fertilizer that spills onto hard landscaping, paving, your driveway and paths should be washed off or cleaned up.

Is Lesco Fertilizer Safe for Pets?

Is Lesco Fertilizer Safe for Pets?

Unless a fertilizer is organic, it is very unsafe for pets. Even with organic fertilizers, it’s best to water the fertilizer in well (washing it off grass leaves, etc.) and keep your pet off the grass for at least 24 hours after application.

Lesco weed and feed fertilizers contain herbicides, so are unsafe for pets – as are all chemical herbicide products.

It is advisable to keep your pet off your lawn for 48 hours and to water the lawn well after that 48 hour period to reduce exposure.

Fertilizers are concentrated chemical mixes, so they are harsh on exposed skin and eyes.

If your pet does walk on the lawn, wash their feet with water. If they display any signs of illness, including vomiting, take them to the vet immediately.
