Fall Nematode Application

The Secret to a Lush Autumn Lawn

As the leaves begin to change and the temperatures drop, it’s time for garden enthusiasts like you to turn their attention to fall lawn care. One often overlooked but highly effective method for maintaining a beautiful lawn is fall nematode application. In this article, we’ll guide you through the when and how of applying nematodes to ensure your lawn stays lush and vibrant.

What Nematodes Are Treating – The Grub Menace:

The Culprits

When we talk about nematode application, we’re primarily addressing a common lawn enemy: grubs. Grubs are the larval stage of various beetles, and they love to feast on the roots of your precious grass. Left unchecked, they can wreak havoc on your lawn, causing brown patches and weakening the overall health of your turf.

The Damage They Cause

Grubs are not your lawn’s friends. They voraciously devour the roots, leading to brown, wilted patches on your once-green carpet of grass. This damage can become particularly noticeable as fall progresses, making early fall the ideal time for nematode intervention.

Why You Want to Get Rid of Grubs:

Lawn Health

A grub-infested lawn isn’t just an eyesore; it’s also an unhealthy one. Weakened and damaged grass is more susceptible to disease, drought, and other environmental stressors. By eliminating grubs, you’re safeguarding the vitality and resilience of your lawn.

Environmental Impact

Nematodes are an environmentally friendly way to combat grubs. Unlike chemical pesticides, they pose no harm to beneficial insects, pets, or humans. Using nematodes aligns with your commitment to responsible gardening and maintaining a balanced ecosystem in your yard.

Protecting Your Lawn from Unwanted Guests

Here’s a bonus benefit of grub control: it stops skunks and other critters from digging in your lawn, and making a mess. Grubs are a delectable treat for these animals, and when they detect a grub-rich buffet beneath your grass, they won’t hesitate to start digging. By addressing the grub issue, you’re also preventing these late-night lawn vandals from wreaking havoc in your yard.

When to Apply Nematodes:

Early Fall Is Key

The best time to apply nematodes to your lawn is in early fall, typically in September. This timing aligns with the life cycle of many common lawn pests, such as grubs, making it the perfect opportunity to target these invaders.

Optimal Soil Temperature

It’s essential to monitor soil temperatures to determine the right moment for nematode application. Aim for a soil temperature of around 10-20°C (50-68°F). This temperature range ensures that nematodes are most active and effective.

How to Apply Nematodes:

Prepare Your Lawn

Before applying nematodes, mow your lawn to a short height and remove any debris like leaves or thatch. This will help the nematodes penetrate the soil more effectively.

Hydrate Your Lawn

Nematodes need moisture to move through the soil. Water your lawn thoroughly before and after application. It’s crucial to maintain soil moisture throughout the process.

Mix and Apply

Follow the instructions on your nematode package for the correct mixing ratio. Typically, you’ll mix the nematodes with water and apply them evenly across your lawn using a sprayer or watering can. Apply in the early morning or late evening when temperatures are cooler to avoid sun exposure, which can harm nematodes.


Fall nematode application might sound like a small step, but it can make a world of difference in maintaining a healthy lawn. By applying nematodes in early fall, targeting the right pests, and following proper application techniques, you’re not only protecting your lawn but also ensuring it thrives in the coming seasons.

So, as you sip on your pumpkin spice latte and admire the autumn foliage, don’t forget to give your lawn some love with nematode application. Your lawn will thank you with a lush carpet of green come spring!
