herbicideSo, what is the difference between a pre-emergent herbicide versus a post-emergent herbicide? Simply put, pre-emergent herbicides are formulated for the weeds you don’t have, while post-emergent herbicides are used for the weeds you already have.

Both choices, are primarily concerned with the same list of culprits: Clover, ragweed, sow thistle, cheat grass, barnyard grass, cattails, dandelions, and multiple forms of crabgrasses. If you’ve just invested a lot of time, or money, into the perfect lawn, you’re going to want to deal with these problems sooner, than later.

We recommend consulting a landscaper prior to application of pre and post-emergents. They will be educated on water to herbicide ratios, watering schedules, and how to avoid problems such as burning your perfect lawn.

Pre-emergent application. Pre-emergents are all about preemptively introducing an enzyme into the soil to prevent weed germination. You know they’re there, but you haven’t seen any yet. Pre-emergents for bedding areas are generally applied in the winter prior to seed germination.

Post-emergent application. These products require even more care than the pre-emergents. They are usually formulated to be stronger, so spraying down your whole lawn is a bad approach. They should be applied in a targeted method in controlled doses. This may take multiple applications. Misuse at this stage can go completely wrong.

As always, talk to your landscaper about any questions, or reservations, about usage. You can contact us at 541-677-0281 or email us at :
