How To Get Rid Of Your Weeds After Rainfall

Tall weeds can create a breeding habitat for rodents and insects, making it a health concern for our customers. We recommend property owners be proactive in maintaining grass and weeds before the situation escalates to a health issue.

A recent Purdue study found 13 weeds likely to emerge on properties after a long rain including morning glories, waterhemp, burcucumber, fall panicum, common ragweed, giant ragweed, yellow nutsedge, shattercane, crabgrass, lambsquarters, smartweeds, nightshades, and barnyard grass. To control these, consider this multistep process below:

1. Apply pre-emergent herbicide

First, you should apply a pre-emergent spray to keep away more weeds, breaking the cycle of constant regrowth. This spray is activated in the top layer of soil, where weed seeds typically sprout, and by design, it stops the plant from growing.

2. Apply post-emergence herbicide

Next, apply a post-emergence herbicide to any existing weeds. This might seem fast, considering we just applied a pre-emergent, but it is a necessary step in maintaining weed control.

Each season after, you will have to spray the post-emergent weed killer less, as the weeds will die off. Ideally, you would eventually not have to use a weed killer at all after a while; however, in most yards, outside infestations prevent that from being a reality. Nonetheless, having your weeds maintained will be reward enough, trust us.

3. Pull and hoe

Because chemical applications won’t make your weeds immediately disappear, some old-fashioned pulling and hoeing will still be necessary. Remove the weed from the root rather than from the ground-level, to ensure the most efficient eradication.

The old saying ‘pull when wet, hoe when dry’ is wise advice when grabbing these weeds. After a drenching rain is the best time for a complete weeding session. Grab some gloves and a small stool or pad to sit on, and go to town.

Tip: The best gardening tool for weeding is an old table fork. You can use it to twist out the roots of the weeds without hurting your fingers. If you have stronger, thicker weeds, you might want to use a stronger tool such as a fishtail weeder.

4. Mulch it over

Lastly, smother the remainder of the weeds with a good layer of mulch. Just like grass, if weeds can’t see the light, they’ll die. You can mulch with anything from wood chips, bark, straw, or even pine needles for an effective smothering.

There you have it! Your yard will be weed-free in no time.
