If you use round up type weed killer, yes. Just be certain not to use brush killer, it inhibits the ability plants to grow for as long as it lingers in the soil. (Which could be years.)

Use a ground cover( Poly Ethylene) instead of weed killer, which is healthy and safe for envoirnament.

I know what you are going for but, black plastic under 5 or 6 feet of snow won't kill anything. Smiling

Maybe should ask what kind of weeds and where. Will they survive under all that snow?
For me, gardening is really just an excuse for playing in the dirt. Admittedly, plants are a satisfying by-product.

Absolutely, it protects from deep freeze rather than kill any thing up here. Thumbs up

if it is a vegetable or edible garden (you didn't say), try to stay away from all chemical weed killers, unless you have a specific need.

Instead of dumping chems on the garden...why not plant your autumn garden?

carrots and parsnips should be good all winter... turnips and mustard and such should have time to give a nice crop before the real cold stuff arrives!

Alternatively, maybe mow / string trim the garden and then sow winter rye or wheat or something to help hold the soil through the winter... turn under in the spring.

The question is:

BrendaLee62 said:my garden is all done for this year if I put weed killer on it will it be safe to plant next year?


The answer: Yes, if you use Roundup or another non-systemic herbicide, your garden will be safe as soon as it dries.

There is NO fall garden up in the Northland.
Carrots planted in spring can be left if covered with leaves to control frost but if it is a truly hard winter that is a crap shoot.
Ditto for parsnips.

Where she is , is not as harsh as where I am but it gets very, very, by Southern standards, cold there.
Snow/rain should wash out any residual by spring and it will be safe at that point any way.

I only use weed killer in my veggie garden for rhizome weeds, Canada Thistle , but have no worry planting potatoes in the same area.

BrendaLee, I am in Michigan just like you and I am contemplating the same issue that you are but perhaps on a smaller scale.
My home came with a beautiful rock garden, 8' by 8' that was invaded by a member of the spiderworts. It crowded out EVERYTHING!! But now the spiderworts have died back completely and things like ice plant and dianthus are beginning to grow. They are free from the shade.
Anyway, I am in the middle of carefully cleaning out all debris prior to winters onslaught.
All my rock garden plants are in clusters or clumps and next spring, in mid March, I will use Round Up sparingly on the dense pockets of spiderwort. Others I will pick by hand. I can't let 2-2,500 stems of spiderwort thrive unchecked like they did for the last two years.

They spread by seeds via chipmunks or squirrels to my raised beds in my front yard. They were fewer in number but I was able to pull most of those this May. But I support using Round Up. Spiderwort looks like grass when it sprouts. I will glove up and wear a respirator, but these darn plants have got to "hit the road" next year!!

Yes, I'm familiar with those early frosts at the end of july up there...

wasn't sure whether you all were dealing with hard frozen ground yet.

Personally, I would never-ever leave the soil bare through the winter.

If wheat, rye, other triticale would grow through the winter, then I would plant that.

As far as spiderwort, dayflowers go... That is what a hoe is for. Rake them out and feed to chickens.

As far as the herbicide washing out?
I'd hate to chance it... bad enough being exposed to that stuff from the grocery... growing my own vittles helps me to have food that hasn't been exposed to toxic substances.

I can't rake them out of my rock garden unfortunately.

Stay away from Roundup and adopt organic gardening instead.
When sprayed with this powerful weedkiller, both the weeds and GMO crops absorb glyphosate, the active ingredient. The weeds die but the crop doesn't. And the weedkiller ends up in the foods you and your children eat.
Instead, put a heavy mulch of straw, grass clippings, chopped leaves, etc. on your garden beds.
The mulch will help prevent weeds from coming up and it will keep your soil from drying out so quickly.
At the end of the season just leave it there and keep adding more mulch each year.
The mulch will decompose and give you a wonderful, rich soil.
If you decide to transition to organic gardening, you may experience a bad year at first because it can take a year or so before the natural balance that exists in nature is restored. There is a prey-predator balance in nature that needs to return. Once Mother Nature takes over, you'll have very few problems with insects.
After that, just use organic fertilizers.

If you must use something to kill weeds, try a solution of vinegar, water, epsom salt, and a few drops of Dawn dish detergent. You may need two applications with this, but it's safer than Round Up. I wouldn't even use this on my vegetable garden, though, but have used it elsewhere with good results. I agree with Heuchera on going the organic route. Round Up is a carcinogen, so it's not a good idea to use it at all, but particularly not in a vegetable or herb garden.

Check out dirtdoctor.com for some great organic ways to kill weeds. Also, 3 inches of mulch helps weeds not to grow.

Very strong, far, far, far stronger than the grocery store stuff is a safe way kill weeds but I doubt it does much to seeds.
