Information for chemical-free lawn care?

Recently joined the subreddit, and found the discussions interesting. Now, unless I'm mistaken, there's a fairly heavy dependence on various weed-killers, etc., to kill weeds or prevent their germination. In my municipality, no chemicals can be used on lawns, so I'm looking for so-called "organic" methods of suppressing weeds and promoting growth of grass. I would appreciate any links to websites or other materials that can help me educated myself on this topic, and find the appropriate approach to improve the grass/weed ratio. I also have pets and children who play on the lawns, so the possible toxicity is also of concern. Any help is appreciated.

If you have an established lawn, it's sometimes not too difficult to keep it relatively weed free without chemicals. I haven't sprayed a single herbicide this year so far. But I regularly walk through to pull any weeds that do emerge.

"Neglected" is probably a better description than "established". Other than cutting it periodically, and pulling the various weeds by hand, we haven't done much with it. The soil is rather dense, and there are many trees growing along the property margins, so tree roots are quite prominent when one tries to dig. I suspect the first thing would be to do a proper soil test and see what we're dealing with. But as I noted, the goal of this post is to be pointed to sources of information so that I could start educating myself. Then, I can start asking the right questions.

In the absence of chemicals, the shadow of the gardener is what a lawn needs most. Weed, water, weed, cut, water, weed, thatch, weed, aerate, weed, fertilize, weed, overseed, weed, water, weed, Ph balance, weed, etc.

Corn gluten meal is often touted as inhibiting seed germination and is promoted as an organic method of doing so.

There are a lot of organic fertilizers such as milorganite that you can choose from.

Trimming the trees around your property can help as well as more sun can promote grass over the weeds.

Other than that it will probably be what has already been recommended to you. Cut high and often, water infrequently and deep, hand pull weeds, manage your pH.

The best chemical free way to manage weeds is a healthy lawn. Long, thick grass will by default crowd out weeds and shadow the soil surface to limit growth. Assuming you have cool season grass I would recommend overseeding and using an organic fertilizer this fall. In the spring you can use corn gluten for fertilizer and preemergent use. You need to go 20lb./1000sq.ft. with the corn gluten to get an effective preemergent. Aside from that, care for you grass with infrequent but heavy watering (frequent light watering will cause shallow rooting that is not good), mow twice a week during times of heavy growth (spring/fall), keep your mower on the highest setting, and weed by hand.

Everything is a chemical. Literally everything. Just saying.

Understood. I did my first degree in biochemistry. But meant in a colloquial way, products not synthetically derived.

Mostly just being a smart ass. But it really bothers me when people are trying to sell their pyramid scheme products that are “chemical free”.

Oh, I know. Same goes with "natural" and "organic". Doesn't make botulism toxin, or arsenic, or aflatoxin or any other "naturally-derived" product safe.

Definitely stop using that chemical called dihydrogen monoxide. If you do this, I guarantee you won’t have a lawn with problems.

Yes, I recognize the formula. It does have a pregenesis origin. And without it, life as we know it wouldn't be possible.

Must live in Canada? I really don't get why governments ban safe lawn care products. So crazy to me.

Part of it's around consumers who aren't using them properly - minimal use, careful not to apply when it's hot, avoid overspray, occasionally just pull a weed, etc. If people are using 2-4D like those guys were using gasoline in Zoolander, then it does a fair bit of environmental damage.

As u/grumble11 says, the bans come from people using the products in unsafe ways. Some of my neighbors in the general area are replacing their grass lawns by wildflower gardens, or rock gardens with succulents and drought-resistant species. We like being on the lawn, so it stays, but we have to be better at maintaining it.

I have recently found this website for lawn care. The chick who is writing it seems to keep it pretty simple which is good because I can understand what she is talking about without having to be an expert. https://greenthumbplanet.com/category/lawn-care/
