To kill dandelions effectively, you need to target the entire plant, especially its deep taproot, to prevent regrowth. Here are the main methods: 1. Hand Pulling or Digging Out

• Use a dandelion digger or a similar tool to remove the whole taproot, which can be up to 18 inches deep. Pulling only the top will result in regrowth

• The best time is when the soil is moist, such as a few days after rain, to make root removal easier

2. Boiling Water

• Pour boiling water directly on the dandelion’s leaves, stem, and root. Repeat twice daily until the plant dies. Be cautious as boiling water can harm surrounding grass and plants

3. Vinegar (Acetic Acid)

• Use horticultural vinegar with 20-25% acetic acid for stronger effect (household vinegar is about 5% and less effective).
• Spray the whole plant carefully to avoid damaging nearby grass or flowers. Repeat applications may be necessary

• A homemade mix of vinegar, lemon juice, and dish soap can increase effectiveness

4. Herbicides

• Apply a selective broadleaf herbicide containing 2,4-D or similar to kill dandelions without harming grass.
• For patios or driveways, nonselective herbicides can be used but will kill any plant they contact.
• Pre-emergent herbicides applied in early fall and spring can prevent seeds from germinating

5. Mulching

• Use mulch or landscape fabric in flowerbeds to block light and prevent dandelion seedlings from growing

6. Other Natural Methods

• Salt can be sprinkled at the base of the plant in dry conditions to kill roots, but avoid contact with other plants

• Raising chickens can reduce dandelion leaves but won’t eliminate roots

Additional Tips

• Mow dandelions before they flower to prevent seed spread, but mowing alone won’t kill the roots

• Regular lawn maintenance, including keeping grass healthy and at appropriate height, helps reduce dandelion invasion

Persistence is key, as dandelions produce many seeds and have deep roots. Combining methods like digging and herbicide or natural treatments improves success
