Buying Guide

The first line of protection against weeds is pre-emergent herbicides. During  winter, zoysia need not be fertilized. However, applying a pre-emergent herbicide on your lawn during the winter season is a brilliant idea, since it   results in a more beautiful lawn in the summer.

Herbicides applied before seed germination create an invisible membrane that stops seeds from rooting. Preventing the germination process can stop weeds from sprouting.

Many pre-emergent herbicides are useful for 30 to 60 days after the application. If the temperature rises, many items can need a new application. The existing weeds in your lawn would not be killed by pre-emergent materials. 

The Dimension brand is ideal for those in search for a pre-emergent for Zoysia grass.  It includes Dithiopyr, a solution which can destroy already sprouted weeds. As a result, you can apply it before or after any weeds appear. It may be applied to existing lawns, industrial areas, and also on ornamental turfs.

These include rough golf course fairways and tee boxes.  Of course, it's effective against crabgrass but it may not be as effective against other weeds.

The intention is to apply it when the weather can't be predicted.  It's impossible to predict when weeds will appear. It could be chilly one day again warm the next day and weeds will appear out of nowhere.

When to use a Pre-emergent Herbicide

Pre-emergent herbicides are better used during the fall or the early spring season. They can be used all year long, but they would only stop new weeds from growing. Since multiple types of weeds will be targeted by spring applications, you'll need to identify which weeds you're trying hard to keep at bay.

If you need to apply a seasonal herbicide, suppose during fall, you're trying to keep winter weeds at bay. Timing too is crucial in this situation. To prevent the winter weeds from sprouting, the best timing would be to add some pre-emergent herbicide during late summer or at early fall. 

How to use a Pre-emergent Herbicide

Pre-emergent herbicides are used in the spring to inhibit the growth of summer weeds. This covers grassy and broadleaf varieties. Until applying the product, ensure that the temperature of the soil is around 55°F or 13°C, better if higher, for at least 36 to 72 hours.

This occurs in most areas of the United States around March and April. If you're applying granular materials, make sure they are watered after applying. This aids the active ingredient's penetration into the soil. Liquid pre-emergent materials, on the other hand, must be watered as well. This occurs when the active ingredients are trapped within the plants.

As a result, it is unable to penetrate the surface when applied. When the soil temperature drops below 70°F or 21°C, add the herbicide to control fall weeds. It's safest to do it for around 5 days straight when the temperature is around mid-70s. 

Final Thoughts

It could still be difficult to choose the right pre-emergent herbicide with six options to consider. The Dimension brand, we think, contains everything you may require.

Although a pre-emergent herbicide is intended to be applied before any weeds grow, it can be difficult to predict when it would be. You won't have to be concerned as much if you use this herbicide. You can get rid of weeds that haven't germinated. If any do appear, you can eliminate them using the same product.
