How to Pick the Best Pre-Emergent for Your Lawn?

You can’t just pick a pre-emergent at random and apply it to your lawn. Depending on various factors, the type of pre-emergent you choose matters a lot.

For one thing, you need to pick a herbicide that’s actually designed to kill the weeds you have. Some pre-emergents kill grass too, so you need to make sure that whatever pre-emergent you’re using is safe for use on zoysia grass.

If you don’t already know this information, then before you pick a pre-emergent you should determine approximately how large your yard is in square feet.

Any pre-emergent will have some kind of indication on the packaging of how many square feet of lawn it will be able to treat, so just look for it and you’ll easily find this information.

Last but not least, the type of substance your herbicide comes in matters too. Herbicides generally come in two types: liquid-based and granule-based.

If you go with a granule-based herbicide, the area you apply the herbicide to will need to be watered either before or after the fact. Some granule-based herbicides allow you to actually mix the granules in with your water supply and spray everything on your lawn at once using an applicator.

In the case of liquid-based herbicides, you always have to pre-mix them with water before you spray them on your lawn.

How to Correctly Use a Pre-Emergent?

When using a pre-emergent, you can’t just spray it on your lawn at any time and expect positive results. The process of applying pre-emergents is a lot more complicated than that and there are several things you need to know before starting.

Firstly, it’s unlikely that the entire population of weeds on your lawn will be wiped out after the first time you apply your pre-emergent.

There are tons of factors that affect how and why weeds are able to grow, and many weed seeds have naturally evolved to be resistant to harsh conditions in any case.

Sometimes you’ll need to apply an herbicide to your lawn more than once for satisfactory results.

You also have to apply pre-emergents at the right time of year and under the right conditions for them to be really effective at eliminating weed. It also depends on how the pre-emergent you’re using works.

The right time and the optimal conditions to use a pre-emergent are going to change a lot as well depending on what weeds you’re trying to get rid of. Do plenty of research on the weeds in your garden and how they grow before looking for a pre-emergent.

In the case of most pre-emergents, they are not effective if used as spot treatments. Weeds can spread out underground to parts of your lawn not covered by herbicide, so you’ll need to treat your entire lawn for pre-emergents to work properly.

Are There Natural Alternatives to Chemical-Based Pre-Emergents?

It’s fair if you’re skeptical about using a chemical-based pre-emergent herbicide on your lawn. Although most of them are pretty safe to use, sometimes you would just prefer to not use any kind of chemical or synthetic substance to kill weeds.

If this is the case, one alternative to chemical herbicides that you can use on weedy areas of your lawn is corn gluten meal. This is a natural pre-emergent, and it works because it has a very high nitrogen content which helps inhibit the germination of selected weed seeds.

Just like other pre-emergents, however, you’ll still have to apply it at the correct time in order to see any results. Corn gluten meal might also not be effective at eliminating some types of weeds, so always do preliminary research to see if it’ll work.

Although it’s not always effective as a pre-emergent, corn gluten meal is also a great fertilizer because it’s so rich in nitrogen. In fact, you can use it continually on your lawn if the turf is well-established.

Some organic lawn and garden care products contain corn meal gluten, so look for this ingredient in their formula if you want to find an effective, naturally derived pre-emergent and fertilizer.
