Prof. Samuel Fitzgerald, Ph.D.When it comes to lawns, they can flourish using nature's own systems and thrive without relying on synthetic chemicals. When I converted my yard five years ago, I noticed a decrease in pests after the transition and an improvement in the soil quality. Make soil health your priority and aim to compost not just regularly, but consistently. Utilize cultural practices in conjunction with organic methods to effectively control weeds.
Natural Weed Removal
- Hand-pull weeds after rain when soil is moist and roots release easily
- Spot-treat with vinegar-salt solutions during peak sunlight hours
- Flame-weed driveway cracks safely with propane torches
Organic Fertilization
- Apply compost tea every 4-6 weeks boosting microbial activity
- Use corn gluten meal as natural pre-emergent in early spring
- Top-dress with aged manure providing slow-release nutrients
Compost applications can stimulate soil biology. Dense, healthy turf naturally crowds out weeds. Apply 1/4 inch layer in spring and fall. Use beneficial nematodes for grub control, apply late in the day. I released nematodes after seeing the damage caused by Japanese beetles to end their infestation.
Create solutions at home in a safe manner. Mix one gallon of vinegar with one cup of salt and a tablespoon of dish soap for a homemade herbicide. Then apply this concoction on sunny days every three days. For fungus issues, combine baking soda and horticultural oil. These will not harm earthworms or soil microbes.
Mow high, at 3-4 inches for shade, which inhibits the germination of weed seeds in the soil. Leave grass clippings that naturally return nitrogen, creating a more resilient and healthier ecosystem. Annually overseed grass, improving density and creating a self-sustaining ecosystem requiring less intervention each year. Now my lawn thrives on minimal inputs.
Slowly transition away from chemical usage. Begin by eliminating synthetic fertilizers, and then focus on reducing the use of chemical herbicides. You'll likely notice your soil microorganisms will recover in a matter of months. You may also see a temporary increase in weeds while nature adjusts and balances things out. You'll also have healthier, chemical-free lawns that are resilient, attract pollinators, and provide a safe space for your family.
