Process To Kill Weed with Boiling Water

  • Boil water in a pot with high sides with no narrow angles or edges because this will cause the water to foam up and spill out. You don’t want any spilling out of the pot.
  • Fill a bucket with cold water after you start boiling the weed killer in step 1 to have it ready so you can immediately rinse the weed with cold water.
  • Place a shower head in front of the pot while boiling and adjust it so that the spray hits any weed on top of the water’s surface, or you can simply use a watering can.
  • When all leaves have been hit by hot steam for long enough, immediately rinse them off with the cold water from step 2 after you place a container deep enough to hold all of the weed because the hot steam can expand up to 3 times in volume.
  • Dry and spread into thin layers on a flat surface like folded newspapers, an old bedsheet, or cardboard box, then sun-dry each day for a few days until dry, dispose of.
  • Ensure that none of the weeds is floating or mixed in with the dirt because this will cause you to have to throw out more stuff than you should.

5 Benefits of Killing Weeds

1. Prevent Weeds from Spreading:

Weeds that are left unchecked can quickly take over your landscaping and cause other types of grasses to die out as a result. Some weeds spread plant diseases and insects that attack plants. Take precautionary methods to prevent the spread by killing all weeds in a large area at the same time.

2. Save Time:

Killing weeds with boiling water will save you a lot of time spent on meticulous weed removal. This is especially true for extremely overgrown areas covered in weeds and grasses, which can be a rather tedious process if done by hand. Boiling water also kills the roots completely, so they won’t grow back.

3. Conserves Water:

Treatment with boiling water is a greener way to kill weeds than traditional methods like using herbicides and potent chemical weed killers harmful to both the environment and human health. Boiling water can also be used on areas of your lawn or landscaping covered in dandelions and other weeds that are not affected by chemical weed killers.

4. Protect Houseplants From Weeds:

If you have houseplants inside your home or office, you will likely want to keep the area around them free of weeds and grasses. If done properly and regularly, boiling water can provide enough protection against unwanted weeds so that you don’t have to worry about them growing back.

5. Preserve New Lawn Grass Seed:

New grass seed is expensive, so it makes sense that you would want to preserve it for as long as possible. A popular way of keeping weeds out of new lawns is with boiling water treatment throughout the summer and fall months, killing weeds before they have a chance to grow and spread.
