Using weed and feed: is it a good idea?

Many homeowners prioritise maintaining a healthy lawn, and the temptation to use products like weed and feed can be strong. These products promise to eliminate weeds while simultaneously feeding your lawn. However, despite their convenience, weed and feed might not always be the best choice for keeping your lawn lush and green. 

In this blog, we’ll explore what weed and feed is, why it might not be the most effective solution for weed control, and what alternatives are better suited for long-term lawn health.

What is weed and feed?

Weed and feed products are a type of lawn care treatment that combines a herbicide (weed killer) with a fertiliser (feed product). The idea is that while the herbicide kills weeds like broadleaf weeds, the fertiliser feeds the grass, promoting a healthy lawn. They are typically marketed as a one-step solution for both eliminating weeds and nourishing your lawn, making it appealing to busy homeowners who want a quick fix for lawn care.

Why weed and feed isn’t the best option for eradicating weeds

Although weed and feed sounds like an all-in-one solution, it often falls short when completely eradicating lawn weeds. One reason is that most weed and feed products require 2-3 applications to be effective, especially when tackling stubborn broadleaf weeds. Each application must be timed carefully with lawn growth cycles, usually during spring or autumn, which can make it less practical.

Additionally, because the herbicide in weed and feed is a general formula designed for widespread weed control, it may not target specific weeds in your lawn effectively. This means you might end up spreading weed control over areas of your lawn that don’t need it, potentially causing stress to healthy grass.

So, when should you apply weed and feed? The answer is - you probably shouldn't. 

Why you shouldn’t use weed and feed on buffalo lawns 

One of the significant drawbacks of weed and feed is that it cannot be used on all types of lawns. Buffalo lawns are particularly sensitive to the herbicides commonly found in these products. Buffalo grass, unlike other grass types, has a thicker and softer texture, and the chemicals in weed and feed can damage or even kill it. If you have a buffalo lawn and apply weed and feed, you might find your grass turning yellow or patchy, which defeats the purpose of creating a lush lawn.

For those with Sir Walter DNA Certified buffalo grass, it's essential to use lawn care products specifically formulated for this variety. Lilydale Instant Lawn stocks herbicides that are buffalo-safe and much more effective for weed control without the risk of damaging your turf.

Weed and feed does little for root strength and development

One of the less discussed issues with weed and feed is its limited impact on root strength and development. While it provides a surface-level green boost, it doesn't contribute much to the long-term health of your lawn's root system. A healthy lawn depends on strong, well-developed roots, especially when dealing with seasonal changes or drought.

Regular fertilisers are designed to penetrate the soil and strengthen the roots, but in a weed and feed product, the fertiliser component may not be as effective. The herbicide can inhibit some of the benefits that come with applying a fertiliser independently. Without strong roots, your lawn is more vulnerable to future weed invasions and won't maintain its green lawn appearance in the long run.

Why it’s better to use herbicide and fertiliser separately

For effective weed control and long-lasting lawn health, it’s generally better to apply weed killer and fertiliser separately. When using them individually, you can target all the weeds specifically with a herbicide, while the fertiliser can focus on nourishing your lawn without interference.

By using herbicides separately, you have more control over which weeds you're targeting, ensuring you’re not spreading weed control unnecessarily across the entire lawn. This method also prevents the overuse of chemicals, which can stress your grass. Additionally, applying fertiliser alone allows it to feed the roots properly, encouraging stronger root development and a healthier lawn over time.

The benefits of Lilydale's herbicide products for weed control

Many of our customers ask us questions like ‘how often should you use weed and feed?’ But, at Lilydale Instant Lawn, we believe that eliminating weeds requires more than just convenience; it requires the right product for your specific lawn. That’s why we stock a range of herbicides that are better suited for various lawn types and are more effective at controlling weeds than traditional weed and feed products. Whether you’re dealing with spring weeds or persistent broadleaf weeds, we have solutions designed to help you control weeds without damaging your grass.

Using a separate herbicide allows you to target problem areas more effectively, eliminating weeds while maintaining the health and vibrancy of your lawn. Lilydale's range includes herbicides that are safe for buffalo lawns and other grass varieties, ensuring that all the weeds are dealt with appropriately without compromising your lawn’s appearance.

How to apply weed killer and fertiliser properly

For the best results, applying weed killer should be done when the lawn is actively growing, usually in the spring or autumn. Ensure that the soil is moist, and avoid mowing the lawn for a few days before and after the application to allow the herbicide to work effectively.

When it comes to fertilising your lawn, make sure you choose a product that promotes both top growth and root strength. At Lilydale Instant Lawn, we offer a variety of feed products designed to provide long-term benefits for your lawn. Spread the fertiliser evenly across your lawn, and water it in to help the nutrients reach the root system.

Alternatives to weed and feed

If you’re looking for alternatives to weed and feed that will help you achieve a healthy lawn, here are a few recommendations:

• Use a targeted herbicide: Lilydale offers herbicides that are effective at eliminating weeds while being safe for various grass types, including buffalo grass.
• Apply a slow-release fertiliser: Fertilisers that release nutrients slowly will feed your lawn over time, promoting both top growth and root strength.
• Improve soil health: Good soil health leads to a strong, resilient lawn. Consider incorporating organic matter or using a lawn topdressing to improve soil structure.
• Overseed your lawn: If you notice bare patches or thinning areas, overseeding with high-quality grass seed can help thicken your lawn, making it more resistant to weed invasions.

For better weed control and a stronger, healthier lawn, it’s best to use herbicides and fertilisers separately.
