Not everything goes fallow in the wintertime. Wintertime weeds are thriving and will wreak havoc in your garden. Be sure you're prepared.
What do 485 million acres of U.Southward. cropland and nigh one billion acres of range and pasture have in common? Weeds. And not but a smattering hither and there. We're talking an army hundreds of thousands strong with new enlistments every day. A unmarried weed can produce 100,000 to 200,000 seeds that tin survive in soil for twoscore years, germinating every spring and autumn without fail.
With prolific seeding like that, it'due south no wonder weeds are spreading at a rate of 4,600 acres per day on federal lands in the western U.S. They toll farmers billions of dollars annually in lost crops, with billions more spent on chemicals to treat them. And at present some species accept developed resistance to the herbicides used to control them.
The numbers and dollars may be dissimilar for private lawns and gardens, merely the weeds are the same. Summer and wintertime weeds are a bona fide nationwide problem. Simply you tin go on your winter backyard and garden nigh or even entirely weed-free with these practices.
Where Do Winter Weeds Typically Pop Up?
Winter weeds — undesired plants that germinate in the fall, grow and seed from wintertime into spring and and then die off or go dormant every bit temperatures increase — tin grow anywhere in that location's soil. They especially like:
- Lawns, even more so if they are thin and unhealthy.
- Areas where infestations have occurred in previous years,
- Regions with excessive rainfall,
- Gardens and lawns where equipment similar lawn mowers and rototillers are regularly used. Both spread seeds.
How Do Winter Weeds Survive During Wintertime?
Plants earn the "weed" designation considering of their farthermost tenacity, thanks in function to a few built-in wintertime defense mechanisms.
Quiescence
This refers to a seed's power to wait in a vegetative state until their required growing conditions are met. One time that happens, it automatically triggers the growth cycle.
Dormancy
Dormancy takes quiescence and adds the biological instinct to successfully establish. In this example, achieving the required growing conditions doesn't necessarily trigger continued development.
An extenuating condition within the seed itself can filibuster growth until its chances of surviving and establishing are at their all-time. It's an astounding display of a complex biological process, and information technology makes dormancy by far the key to winter weeds' survival.
Roots
Strong root systems help certain winter weeds survive harsh weather condition. Dicot winter weeds have large taproots that make uprooting more hard. These roots also sprout new growth if cut.
Perennials always take parts of their roots in the ground, storing up the free energy they need to grow rapidly and aggressively. In that location are too some wintertime weeds that grow from rhizomes, notorious for their fast, lateral spread and their ease in sprouting new plants.
Types of Winter Weeds
Winter weeds are categorized based on their structure (broadleaf or grass) and life wheel (annual perennial, or biennial). These are important classifications considering different life cycles and structures require different methods of control, especially with herbicides.
Many of the more widespread broadleaf winter weeds are as well annuals. Stellaria media (mutual chickweed), Lamium amplexicaule (henbit), Lamium purpureum (purple deadnettle), Cardamine hirsuta (lamb's cress) and Veronica arvensis (creeping Veronica) are the most widely seen examples.
Linaria vulgaris (wild snapdragon) is also a broadleaf winter weed, merely unlike the examples to a higher place, information technology is a perennial. Information technology also goes by toadflax or butter-and-eggs. Another well-known winter broadleaf perennial is Taraxacum officinale (dandelion).
The nigh well-known annual grass weed is Poa annua (annual bluegrass). Its hard-to-kill nature makes it a pervasive problem throughout the U.S.
How To Control Winter Weeds
A healthy, dense, lush lawn is by far the best way to control winter weeds. To accomplish this, start in the fall with the post-obit steps. These work for lawn and garden applications.
- Apply pre-emergent herbicide earlier wintertime weeds begin sprouting, to target the seeds and root systems of perennials.
- Spot treat or remove whatever weeds already visible.
- Fertilize.
- Apply mulch to starve seeds of nutrients from the sun and provide a growth barrier.
- Avoid non-targeted watering which benefits weeds too. Implement baste irrigation in garden beds so water is directly routed to plants.
- Limit digging and tilling which tend to spread seeds.
After implementing these preventative measures, inspect your garden regularly to discover weeds every bit early on as possible. Remove or treat weeds the instant you observe them. Killing them earlier they drop seeds prevents infestations in years to come.
When treating sprouted weeds, you lot have two options.
Manual Removal
Weeds without deep roots or runners that grow in relatively contained patterns can be dug out by hand. All traces of the weed must be dug out, taking care to shake or disturb it as petty equally possible. You tin practice this with your hands, but a manus tool makes it much easier.
This stand-up weed removal tool is a good option. It's easy to use and allows you to extricate the weed slowly and carefully, which is essential. I've always liked uncomplicated mitt trowels with a serrated border. Corona, which makes first-class hand tools, makes several hand weeders. I use their transplanter equally a hand weeder and dear how it works.
Herbicide Application
The best herbicide depends on the blazon of wintertime weed, the cultivated grass or plants being affected, and the climate. Equally some weeds develop resistance to certain treatments, it's oftentimes more than constructive to alternate between two herbicides.
The Three Types of Herbicides
Chemical Herbicides
For broadleaf weeds, look for products with triclopyr, dicamba, MCPP or two, 4-D. These are the active ingredients found in selective herbicides that kill broadleaf weeds but not your grass. Some products, called two-way and iii-way herbicides, have two or more active ingredients.
Bonide makes a powerful option with triclopyr and dicamba. Another popular pick is a Fertilome production, which has two, 4-D and dicamba.
Grass weeds nowadays a bigger challenge considering they can't be treated with a herbicide without harming your cultivated backyard. If the lawn is completely fallow or you programme to re-sod, go for strong, systemic and not-selective herbicides containing glyphosate (systemic) or diquat (contact). Systemics are effective on actively growing plants, then those in dormancy — similar your lawn — are usually unharmed.
Information technology's worth noting that glyphosate continues to stir up some controversy despite findings by the Environmental Protection Agency (EPA) that it's not a public health run a risk. Information technology's not-carcinogenic if used exactly as labeled. Be mindful that a non-selective herbicide, exist it contact or systemic, will impale part or all of anything it touches.
Compare-N-Save makes a glyphosate option that works well and is economic. Ortho's GroundClear contains diquat and is besides affordable. Both products have high satisfaction ratings.
All-Natural Herbicides
If yous prefer all-natural herbicides, the nearly tried-and-true ingredients are vinegar and acerb acids, sodium chloride (table salt), soaps, citric acrid and essential oils. You can purchase products already mixed or products that require adding water. Yous also can mix your own recipes at home.
Near all-natural or organic herbicides are non-selective and will impairment or kill anything they come in contact with. All-natural selective herbicides are harder to observe, only out in that location.
A vinegar-based not-selective that works well is Natural Element'south Weed Killer. OrganicMatters proprietary blend of vinegar, sodium chloride, clove oil, lemon juice, sodium lauryl sulfate and water is another tried-and-true all-natural not-selective.
Reduced-Risk Herbicides
Thanks to green chemistry and innovations, there'southward a third pick: reduced-take a chance herbicides with active ingredients similar mesotrione and imazamox.
I've e'er liked Tenacity and regularly recommend it. Tenacity was granted a reduced-risk status by the EPA considering information technology uses mesotrione equally the agile ingredient. While it'south toxic to many kinds of weeds, in that location are no cancer-causing ingredients, and information technology's been deemed safe to use on lawns where children and pets play.
