what is best for killing weeds without killing the grass.I used a weed killer but it left a lot of patches?

Answer 1

If it's dandelions, which it probably is, there's a non-toxic substance made from corn called corn gluten meal. It prevents the seedlings of dandelions and crabgrass from growing new roots. Apply it three times a year, every four months. The first year it's said to reduce crabgrass and dandelions 70 percent and up to 95 percent if used year after year. Mowing, in and of itself, reduces weed growth by preventing the weeds from being able to go to seed. Look at that! No poisons! Good luck!

Answer 2

ignore with regards to the weed killer. something with the observe 'killer' in it won't do your tomatoes, or you thru extension, any stable. those chemical compounds stay in circulate for an prolonged time: in the top, you, or your infants or your pets will purely finally end up soaking up them. relatively, purely dig up the weeds. It takes slightly time, the 1st time, yet whilst they're long gone there are various approaches for protecting them under administration: mulch, coverings of each and every type (i'm guessing you're in a small homestead backyard). a great form of folk are taking element of their gardens returned, between the useful outcomes perhaps of the recession. yet do no longer finally end up poisoning your self: the great component approximately becoming your individual meals is you fairly do no longer ought to apply each and all the weed killers and chemical compounds the worst of the economic growers use -- out of no longer something different than greed.

Answer 3

Dan G is right. If you have broad leaf weed, as the name implies, use a weed killer that has 2-4D as the active ingredient. Weed-B-Gone is one. Follow label directions and spray when the plants are actively growing, generally in the spring. Weed and Feed fertilizer contains 2-4D, I you have grasses, don't use Roundup, as it will kill everything. Try a pre-emergence in early spring, March if in upper mid-west. Fertilizing throughout the year will produce a healthy lawn that will choke out many future weeds.

Answer 4

Try those Weed and Feed type of products.

They need a careful application rate but will kill broad leaf weeds since those wide leaves pick up a lot of the killer particles. That makes the weeds overgrow until they exhaust their food supply and shrivel up. Skinny grass leaves do not pick up a fatal dose. In fact they are encouraged to grow (which is where the "Feed" part of the name comes in.)

Answer 5

Any kind of killer, I would think, would leave patches. It may kill the weed, but the remains from it are still there. I suggest hand pulling them, if you have the time.

I suggest using the weed killer before they get real bad, if you have a bunch of minor weeds. Then you kill them before they get huge, suck the life out of your beautiful, green grass, and leave ugly brown patches that stick out like sore thumbs once they die. Aren't those things an absolute pain? ./me grumbles

Good luck with your weeds... they can be a pain in the apple.

Answer 6

The best all around solution is no grass. But since you like grass, I would suggest an organic approach and trash advice about poisonous chemicals. Do you want to breathe fresh air and sit on your lawn without the after effects of poison? Here is what is good for your grass, your body, and the planet. In the fall, you put a layer of good compost over the entire yard. It will look a little goofy but who cares in the winter? The compost will enrich your grass and choke out your weeds. Your grass is a hardly plant and will push itself back up right through the compost and will be healthier from the nutrients. The weeds will have a struggle and most of them will not thrive. Your grass will thank you for all the good stuff that compost added to the soil and the weeds will be gone.

Answer 7

Most any spray on weed killer will kill indiscriminately. Pulling weeds is pretty much usless bacuse you can never get every piece of root and they will only come back.
Best to just write this season off and begin anew next year. Start off early and apply a good quality fertilizer with weed control. Apply per direction. It will take a couple fo years to become totally weed free but there is really no quick fix.

Answer 8

Grab and pull annuals; that's also useful for most, but not all perennials. Use something like a wiped application of glyphosate for really tough perennials like johnsongrass or canada thistle.

One of the major ways to control weeds in lawns is to mow correctly for the species in your lawn, with a sharp blade. And take care of any soil tilth issues.

Weed and feed type products can be quite polluting... and we all live downstream.

Answer 9

BROADLEAF herbicide. There are many brands, not one much better than the other.

As far as browning, only a few things will cause this:

too concentrated of a solution - or it is too hot when applied. check the msds pamphlets that come on most good quality herbicides, and it will tell you the maximum temperature and mixing ratio

clear up all browning by applying and heavily watering in AMONIUM SULFATE.

Answer 10

Yes weed and feed is best
if you wer left with patches, it may have been spread unevenly

Use a spreader if you can
