Can you aerate after pre-emergent?

While research has shown that aerating your lawn after the application of a pre-emergent herbicide (available on Amazon) will not hamper herbicide effectiveness, aerate your lawn before applying these products possible so as not to disrupt the chemical barrier that the herbicide forms over the soil.

Should you overseed before or after aeration?

While lawn aeration can take place in either the early spring or early fall (we recommend applications during both seasons), overseeding is best paired with the fall application.

What should I do before and after lawn aeration?

Be sure to water your lawn thoroughly two days before aeration. The tines on the aeration machine penetrate loose soil better than dry soil. If the soil is too dry, the tines will have trouble effectively piercing the ground. Avoid aerating immediately after an extended period of rainfall.

What month do you put down pre-emergent?

Early spring and fall are the most effective times to apply pre-emergent herbicides. Applying a pre-emergent herbicide will prevent seeds from sprouting, but the most effective times to use it are in the spring and again in the fall.

Is it too late to put down pre-emergent?

When it comes to pre-emergent weed control, timing is everything. Pre-emergent herbicides are only effective if applied before the annual grass weeds emerge. Apply too late and the pre-emergent herbicide will be totally ineffective.

Can you put down too much pre-emergent?

“If an applicator applies too much herbicide, not only is it not cost effective and a label violation, this may injure the desired turfgrass depending on the rate and product used. An excessive application may also prevent the proper establishment of grass seed later in the season.”

How long after aeration can I mow?

You mow too soon. After you lay down your seedlings, they’ll need time and the right environmental protection to grow. They’ll need to acclimate and set roots before the first mow, so during the first two to four weeks post aerating and overseeding, don’t mow.

Do you leave plugs on lawn after aerating?

After you finish aerating your lawn, let soil plugs or extra soil dry where they fall. They’ll break down in rain or crumble the next time you mow, adding beneficial soil and organic matter to your lawn surface.

Will rain wash away pre-emergent?

Soil-applied, pre-emergence herbicides applied at the beginning of the growing season require rainfall or irrigation for activation. This water turns the herbicide into a solution that can be taken up by weeds. Too much rain, however, will cause the herbicide to become diluted and leach or wash away.

Do you mow before pre-emergent?

Healthy lawns make it difficult for weed seeds to germinate, especially with a round of preemergent herbicide applied to the grass. Typically, you need to mow your lawn once a week to 2 or 3 inches tall before applying the preemergent.
