How to Use Pre-Emergent Herbicides

Pre-emergent herbicide works by putting an invisible barrier down, in granular or liquid form, over the top of the soil. This will stop the weeds from germinating above the soil line. To reduce the number of weeds, or eliminate them altogether, a pre-emergent should be applied at least twice a year. We recommend using them at the beginning of spring and fall to attack the problem before it starts! Once the weeds start to grow in your yard, you will need to start pulling them or using post-emergent products to stop the spread.

Applying a pre-emergent herbicide is an easy way to spend less time working in your yard and more time enjoying it! Keeping your weeds in control not only ensures an attractive landscape but creates a much healthier environment for the rest of your trees and plants to flourish.

Below are pre-emergent herbicides we recommend and sell at all our Moon Valley Nurseries locations. Come in and get yourself ready to fight those intrusive weeds once and for all. Our nursery experts can help find the best products to use in your yard for the best results!

This is the concentrated form of the Weed Impede RTU listed right above. This contains a full-strength concentrate. So, while it's not ready-to-use right out of the bottle, you will get a more potent concentration of herbicide. We recommend the concentrated form for large yards with a pattern of massive weeds issue.

More Ways to Fight Weeds in Your Landscape

Remove Existing Weedsweeds_orig-1

Every second a weed is left to grow in the yard is a second that more seeds could be falling into the ground, ready to become its own weed and take up more space in your yard. So, what’s the best way to gain control of your landscape? Spray regularly during peak growing conditions to be pro-active against the infestation.

Dealing with weeds is never a fun way to spend a weekend morning. However, it does need to get done, and the sooner it gets done, the better. Each day allows the weeds root system to grow deeper and stronger, while the flowers have more time to pollinate and spread EVEN MORE weeds around the yard.

All you need is a pair of gloves, a bin/bucket for all the weeds you pull, some knee pads/towel to give your knees a bit of protection, and, if you ask nicely, a friend to help you out! Remember to remove the entire root from the ground. For additional assistance, a hoe or shovel can help remove the roots that have gone deep enough to withstand being pulled by hand.

Add Mulching in Your Yard

Weeds, like every other plant, need sunlight to survive. The mulch acts as a barrier to keep the weeds seeds from getting any sunlight, essentially smothering them. If using mulch to suppress weed growth, be sure that the mulch is at least 2 inches deep. Replenish the mulch, as needed. For added protection, cover the ground with newspaper or cardboard before adding the mulch. 

Design Close Planting

Designing close planting is exactly what it sounds like - It’s the concept of planting shrubs, ground cover, or grass materials close to each other. Some people enjoy close planting due to the overall aesthetic. This is also a great way to keep weeds from growing since they will not have space or sunlight to grow successfully.
