Dandelions (Taraxacum officinale) can be a pest in your yard, garden or between cracks in your patio. These perennials grow in U.S. Department of Agriculture plant hardiness zones 3 though 9. Hand-pulling can remove the problem temporarily, but they reseed and grow back quickly. It's not necessary to use chemical herbicides to kill dandelions. Home remedies work just as well when applied correctly. Commonly used and inexpensive household products can be used to kill dandelions without spreading toxins through your landscape.
1. Boiling Water Method
1 Boil a kettle of water.
2. Boiling Water Method
2 Pour the boiling water onto the dandelions to kill them. This works best for small areas, such as cracks in patios or walkways.
3. Boiling Water Method
3 Repeat the process as often as need to kill any regrowth.
4. Vinegar Method
1 Fill a spray bottle with 3 parts white vinegar and 1 part dish detergent. White vinegar without dish detergent also works, but the detergent helps the vinegar stick to the leaves.
5. Vinegar Method
2 Spray the dandelions thoroughly with the vinegar mixture. Spray the plant and the soil.
6. Vinegar Method
3 Reapply the vinegar once every month unless dandelions and weeds are the only plants growing in the area.
