I have these weeds in my front yard that is infesting my lawn. I have already pulled out 20-30 of these little cabbage looking weeds and there’s a 100 more to go! These things leave nasty holes in the ground and I’m afraid this will destroy my lawn even more.

I am using this tool called Weed Hound to pull them out, since these roots are deep. This tool is efficient in pulling these things out, but the cost is a deep conical hole.

Here are some pictures:

the plant the long root the holes

Here are my questions:

  1. What are these things? We just refer to them as yard cabbage because it kind of looks like cabbage.
  2. Do these serve any purpose to wildlife? Would they be food for any wildlife around me? Or do they just give oxygen and kill my grass?
  3. Is there a wise way to kill these things and not leave 3” holes all over my yard? I’d prefer not to use harsh chemicals because I want the wildflowers to bloom still but these things don’t bloom flowers and just look really ugly. Anything I can spray that won’t kill wildflowers?
  4. If pulling out is the only option, Any ideas or suggestions on fixing all the holes in my yard?

Thank you

    Not really wild life, but chicken like them. In any case, remove them. If some wildlives like it, you will not see many of them. Apr 20, 2021 at 13:40

It looks like the tool you're using is doing a good job at removing the weeds and their deep tap roots, which is essential to preventing them from growing back. Short of using chemicals, you've already found the most efficient way of removing them.

If you want to fill in the holes, tap the loose soil off of the weed roots. Pack that soil back into the hole, and push the dirt around the edges of the hole into the hole. If necessary, you could get a bag of topsoil to fill in the holes. (Note that topsoil is a different product from potting soil and compost.) However, if you can tolerate having those holes in your lawn, they may actually be beneficial. Lawns can benefit from occasionally being aerated to reduce soil compaction and thatch buildup.

Your lawn doesn't look especially healthy. The grass looks rather thin and clumpy, with bare dirt visible between clumps of grass. A healthy lawn with dense grass cover makes it harder for weeds to get established. Taking some basic steps to improve your lawn health will help prevent new weed problems in the future. It might benefit from raking out the dead leaves and grass, maybe aerating the soil some more, then over-seeding with good quality grass seed. Mix the new seed with good quality top soil and apply them together, or put a thin layer of soil on either before or after the seed, then water liberally and regularly until the new grass is well established.

If you did want to use chemicals, you would need a systemic broadleaf weedkiller sold for lawn use. Systemic means it kills the roots as well as the leaves (the opposite of a systemic herbicide is a contact herbicide). Since these weeds have substantial taproots, a contact herbicide would not kill them permanently. Broadleaf means it kills broadleafed plants (also called dicots), but not narrow-leaved plants (also called monocots) like grasses and sedges. Wildflowers are also dicots, so a broadleaf herbicide will kill any wildflowers you get it on. However, I'm not seeing any plants other than grass in the photos you showed. Most systemic broadleaf weedkillers intended for use on lawns will only kill the weeds you put them directly on, and shouldn't spread out through the soil to affect nearby plants. Look for a product whose main ingredient is 2,4-D. If it has additional active ingredients, double-check the label to make sure those ingredients are not herbicides that will linger in the soil and prevent seeds from germinating. Key words would be "pre-emergent" and "soil residual."

Your weeds might be cutleaf teasel seedlings. Although I'm not 100% certain in that ID, I'm confident that your weeds are the rosette form of a weed that will eventually "bolt," or grow a tall stem which will produce a flower. That flower will make a large number of seeds. You don't want that to happen, because those seeds will produce a huge number of new weeds all over your lawn, undoing all your hard work so far. So the deciding factor between using chemicals and continuing to remove the weeds painstakingly by hand, is whether you can get rid of them before they produce seeds. Flowering time depends on the species, but if they're teasels the process will probably start in late May or June, with seeds within a few weeks after flowers. If your weeds do start blooming, it will probably be too late to kill them with just a systemic herbicide before they set seed. At that point, you could cut down the flowering stems and apply herbicide, or mow them repeatedly every time they start to regrow the flowering stems. At some point a few plants will probably manage to grow flowers on a very short stem below the level of the mower blades, so watch out for those and remove the entire plant before they go to seed.

  • Thank you for the wonderfully detailed answer. I’ll go through your answer and respond with any comments. Apr 19, 2021 at 21:57
  • You can also deadhead the weeds if they flower, before they set seeds, of course. My nieghbors think I'm nuts because I deadhead the dandelions in my lawn (I work seasonally until mid-July, which means I can't get to the weeds until mid-summer; deadheading keeps the weeds in check until then).

I'm a couple years late on this but...I take a Phillips head screwdriver and poke a hole in the middle, have sports bottle with a pull open top of vinegar and pour an ounce in the hole. Dead in a week. If the grass is affected, it's green in a couple weeks.
