What you can expect from today's WeedFoe
You should expect to see some visible signs of weed decline within a week to 10- days. If pre-emergence products were also applied, you can expect up to four months of weed germination control, unless you have an extremely wet site in which case we may need to treat more often.
For the best control of any future weeds, please leave treated beds undisturbed. You can add rooted plants in the treated beds (seeds will not germinate). Move the top 2” of soil aside, plant, then move the treated soil back. If you decide to plant in the treated beds, please remember that any disturbed soil will be more susceptible to weed seed germination. And more cost will be incurred to control.
If weeds do show up, rather than pulling, you can spot spray with Roundup. It may be tempting to “clean up” the beds by removing the weeds as they die, however, you will get the best results if the dying weeds are just left to decompose or cut off at ground level This will help keep the weed barrier in place.
Note- it is important to be consistent with the pre-emergent applications regardless of visible weeds or not. This will ensure that the pre-emergent will be available in the soil when the weed seeds begin to germinate keeping your beds clean.
Pre-emergent herbicide is the focus of WeedFoe treatments.
These products will need to be watered in by rainfall or irrigation (at least 1/2 inch) to help prevent weed germination. We will also be using post-emergent products to take care of existing weeds.
Some weeds can be quite persistent and it will take a combined effort to get them under control
Northern willow herb
Sometimes falsely referred to as Fireweed, Northern willow herb is a pretty, yet highly invasive weed. It produces thousands of seeds which can germinate in as soon as two days after making contact with the soil. This weed commonly comes into the landscape in container plants, and makes itself quite at home once introduced. Pre-emergents are no match for this wandering beauty so it is imperative that these be removed before going to seed. This weed loves to germinate in and around desirable plants in which case they should be hand pulled, and disposed of.
Considered a living fossil, horsetail is one of the oldest plants on the planet, primarily because it is one of the toughest to eradicate. This is an invasive prehistoric plant that loves wet acidic sites. It spreads by spores, rhizomes and tubers.
When you’re faced with a patch of horsetail growing where you don’t want it to, try to resist digging. You won’t be able to get it all, some roots can reach 10 feet long, and even the smallest piece left behind will generate more. While not a quick solution, horsetail can be somewhat controlled by eliminating top growth repeatedly using herbicide and/or cutting off the green growth above ground as it appears. With persistence the plant can eventually be beaten back.
Casoron may be used effectively in some sites where the plant material and lay of the land will tolerate it.
Creeping buttercup’s competitive growth crowds out other plants, especially in wet soils. One plant can spread over a 40 square foot area in a year. Creeping buttercup also depletes potassium in the soil and so can have a detrimental effect on surrounding plants. Because creeping buttercup can tolerate heavy, wet soils, it can be a particularly bad problem on well-watered lawns, wet meadows and poorly drained pastures.
