3 best organic crabgrass controls

Organic crabgrass control methods are used in gardening and lawn care to manage crabgrass infestations without the use of synthetic chemicals or herbicides. Crabgrass (Digitaria) is a common weed that can invade lawns and gardens, competing with desirable plants for nutrients, water, and sunlight. Organic approaches to crabgrass control are considered more environmentally friendly and safer for pets and wildlife. Here are some key points about organic crabgrass control:

  1. Manual Removal: Hand-pulling or digging out crabgrass is an effective organic method. It's essential to remove the entire root system to prevent regrowth. This method is most practical for small infestations.

  2. Mulching: Applying a layer of organic mulch, such as wood chips or straw, to your garden or around plants can help prevent crabgrass growth. Mulch blocks sunlight and hinders weed germination.

  3. Mowing Practices: Maintaining a healthy lawn by mowing at the proper height (usually 2-3 inches for most grass types) can help shade out crabgrass and other weeds. Mowing too short can promote crabgrass growth.

  4. Healthy Lawn Care: Fostering a strong and thick lawn through proper watering, fertilization, and aeration can make it more resistant to crabgrass infestations.

  5. Corn Gluten Meal: Corn gluten meal is an organic pre-emergent herbicide that can help prevent crabgrass seeds from germinating. It works by inhibiting root development in newly germinated seedlings. It's best applied in the spring before crabgrass seeds start to sprout.

  6. Vinegar-Based Herbicides: Some organic herbicides are vinegar-based and can be used to spot-treat crabgrass. These products contain acetic acid and can be effective for smaller infestations.

  7. Boiling Water: Pouring boiling water directly onto crabgrass can kill it by destroying the plant cells. This method is best suited for isolated patches of crabgrass.

  8. Hand-Held Weed Torch: A weed torch that uses high heat to burn weeds can be used to spot-treat crabgrass.Exercise caution when using this method to avoid damaging desirable plants.

  9. Competition: Planting dense ground covers or spreading plants that compete effectively with crabgrass can help reduce its growth.

  10. Proper Seed Selection: When reseeding your lawn, consider using grass varieties that are more resistant to crabgrass.

It's important to note that organic crabgrass control methods may require more patience and ongoing maintenance compared to synthetic herbicides. Additionally, prevention is key in organic lawn care, so maintaining a healthy lawn and implementing practices to reduce crabgrass seed germination are essential steps.

User questions & answers

Question: Do I use this before or after I fertilize my lawn in the Fall
Answer: I wouldn't necessarily use this in the Fall. September is a nice cool month to do some reseeding, and you can't put this down within 6 weeks of seeding the lawn. I tend to do a March application and a 2nd April application, leaving me a window to seed the lawn in June. Always remember, June and September are the 2 best months to seed your lawn. I also wouldn't put this down in the fall because crabgrass does not tend to germinate in the fall, it germinates in March and April.
Question: Is this effective against crabgrass
Answer: I used it for the first time this season. I couldn't see that it did anything although I understand that it should be used for 3 consecutive seasons to see significant results. I wasn't pleased with the size of the pellets (rabbit food size). It took several rain events for the product to dissolve. Maybe this is better but it just wasn't what I expected. In the spring I plan to use a chemical crabgrass preventer. I'm changing over to a zoysia lawn. Zoysia may go dormant and turn brown in the winter but it requires no watering and less mowing in summer. In a few seasons I won't need any fertilizer or weed killer (except for spot treatments).
Question: Can this be used in the garden as well as the lawn
Answer: Does this kill the grasses that produce those nasty "Foxtails"? I have animals, vegetable garden, etc. and need a better way to kill these weeds/grasses before they produce the foxtails. Trying to "weed-wacker" them down before they get the foxtails is not always possible for me due to health issues.
Question: Is this a good product to use on gravel walkways to avoid weed growth
Answer: Mike McGrath says: Spread even the finest quality corn gluten on established weeds like those walkway ones, however, and you'll simply be feeding them. Mulch,vinegar, flame, hoeing and/or hand pulling are the answer here-and in that large-scale, Master Gardener situation. Yes, you could prevent future weeds by dusting with corn gluten every six weeks, but it would be hugely expensive and you'd be wasting all that great nitrogen fertilizer if there weren't 'wanted' plants growing in that area.

User questions & answers

Question: Can I use on a DG path
Answer: I’m not sure what a DG path is, but it’s a strong vinegar solution that’s environmentally healthy
Question: What is thw shelf life? This was asked before but i do not see an answer.....debating 1 vs 2.5 gallon buy...thanks
Answer: Hi Great question - The shelf life is literally forever. I have tested juice that was more than 3 years old and the great results were still there. It turns out that Vinegar and Ocean water do not lose their strength.
Question: Will this kill invasive vines and shrubs? Looking for an organic product that can do that and having trouble finding
Answer: It’s really crucial to thoroughly spray whatever it is you want to delete from your area. Then if it does re-emerge, it’s critical to repeat the application again thoroughly covering & saturating this plant that you want to rid. That should take care of it completely.
Question: How long until you can plant in the sprayed area? I need to clear weeds before putting in ground cover
Answer: Hi - Great question, safe to plant when dry.

Our True Story - How Doctor Kirchner Natural Weed Killer was born.

Until that diagnosis is handed to you... After a more than a dozen years in the landscape maintenance business I got that diagnosis. Forced to sell my thriving business to get away from the chemicals that caused my illness and not sure what door would open next. A very good friend suggested looking at alternatives to weed control, I did, and what I learned was amazing. Within a year we had a formula, proof of concept and a simple business plan. Word spread quickly that a safe product was available. We work 7 days a week to ensure our customers receive a quality product in a timely manner.

User questions & answers

Question: Can you seed after you lay this product
Answer: google kudzu and learn how it was introduced into north america and spread through its use as a soil stabilizer during road building projects during the depression. it is an invasive species. repeated applications of Bonide should keep it in check - but it may be a long battle. be careful not to spray Bionide on desired species.
Question: It’s a factor for dandelions
Answer: Maybe once a month. It takes longer then roundup to see results. Almost 2 weeks but nothing comes back and I use half as much toma gallon vs. roundup. I like it much better.
Question: Does this come with a shaker, or do you need a spreader to use
Answer: No, it kills anything you spray at. So be careful when you spray weeds
