What this article covers:

Does Fertilizer Kill Weeds?

The primary function of grass fertilizer is to feed your grass, not to eliminate weeds. Fertilizers provide essential nutrients that grass needs to thrive, such as nitrogen, phosphorus, and potassium along with micronutrients such as iron and boron

These nutrients boost grass health, making it more robust and capable of outcompeting weeds over time. However, standard fertilizers are not designed to kill weeds directly.

That said, some grass fertilizers also function as pre-emergents, preventing weeds from germinating in the first place.

As lawn care experts, we've curated a premium collection of lawn fertilizers to cater to your lawn's needs.

Perhaps you're asking yourself "do I need to fertilize my lawn?" and you're stuck between many choices.

For this, we recommend the 0-0-7 Pre-emergent Lawn Fertilizer, a powerful weed prevention lawn fertilizer without any nitrogen. 

We're also proud to present the Triple Super Phosphate 0-46-0, specially formulated to address phosphorus deficiencies. This high-phosphorus fertilizer provides a powerful boost to your lawn's root development and overall health.  Always perform a soil test to see if your lawn is deficient in phosphorus before applying Triple Super Phosphate.

What Kills Weeds Effectively?

The most effective way to kill weeds is through the use of herbicides or weed and feed for lawns products. 

Herbicides specifically target weeds, killing them without harming your grass. These chemicals are formulated to disrupt the growth processes of weeds, ensuring they are eliminated from your lawn.

Weed and feed products combine fertilizer with herbicides, providing the dual benefits of feeding your lawn and killing weeds simultaneously. However they are not as effective as performing fertilization and weed killer separately.

This combination ensures that your grass receives the nutrients it needs to grow strong while effectively controlling weed growth.

Weed and Feed vs Herbicides

Based on our observations, weed and feed products offer convenience, especially if you're looking to tackle both feeding and weed control in one go.

These products simplify lawn care by combining two essential tasks, saving time and effort. However, standalone herbicides can be more potent and targeted, ideal for lawns heavily infested with weeds.

If your lawn is suffering from a significant weed problem, using a standalone herbicide will be more effective and is highly recommended. 

These products allow for precise application, ensuring that weeds are directly targeted and eliminated without affecting the surrounding grass.

How Weed and Feeds Work

Weed and feed products work by delivering a mix of nutrients to the grass while applying herbicides to the weeds.

The herbicides in these products are selective, meaning they kill only the weeds, leaving your grass unharmed.

This dual action is perfect for maintaining a healthy, weed-free lawn. The fertilizer component promotes vigorous grass growth, helping the lawn to outcompete any remaining weeds.

Using a product like this ensures that your lawn remains lush and green while being free from unwanted weeds.

How Herbicides Work

Herbicides function by targeting specific plant processes unique to weeds. They disrupt the growth of weeds, effectively killing them over time.

There are two main types: pre-emergent, which prevents weed seeds from germinating, and post-emergent, which kills existing weeds.

Pre-emergent herbicides form a barrier in the soil, stopping weed seeds from sprouting. Post-emergent herbicides, on the other hand, are applied directly to the foliage of existing weeds, killing them at the root.

We recommend applying a blanket application of weed control to your lawn twice a year ensuring all weeds are controlled.  By using a battery operated sprayer, it makes it very easy to spray your entire lawn.  However, if your lawn is smaller, a pump sprayer will work just fine.

By understanding how these products work, you can choose the right type of herbicide for your lawn's needs.

Which One Is Better?

Deciding between weed and feed products and standalone herbicides depends on your lawn's specific needs.

If you're dealing with a minor weed problem and want to boost your grass's health, a weed and feed product may do the job just fine, but it is not that great in killing all weeds.

It offers the convenience of feeding and weeding in one step. However, for severe weed infestations, or if you need to target a certain weed, standalone herbicides are much more effective. 

These products provide a more targeted approach, ensuring that persistent weeds are eradicated. Assess your lawn's condition to determine which option will provide the best results for a healthy, weed-free lawn.
