How to permanently get rid of annoying pavers weeds
Next, it’s time to destroy the weeds growing in your brick pavers.
Pesticides and organic weed killer
While the best way to control weeds is to pull them out manually (roots and all), it may not be practical in tight spaces such as between brick pavers and gravel. And using pesticides or organic weed killers becomes a viable option.
Opting for organic alternatives ensures the absence of harmful chemicals while maintaining potency against weeds. Just make sure you read the instructions carefully before you begin.
Look for distilled white vinegar with a high acetic acid concentration (around 5-20%). Applying vinegar directly to weeds on a dry, sunny day is recommended to ensure thorough coverage. However, vinegar can also harm them, so avoid spraying plants you want to keep.
How to kill weeds with vinegar
- Choose the right type of vinegar with a high acetic acid concentration (around 5-20%). The higher the concentration, the more effective it will be.
- For a basic vinegar weed killer, you can use undiluted vinegar. Add a small amount of dish soap to help the vinegar adhere to the plant surfaces for a more potent solution.
Boiling water method
Boiling water is another cost-effective solution to permanently stop weeds from growing in pavers. Simply boil water in the kettle and carefully pour the boiling water over the weeds.
How to use the boiling water method
- Heat water in a kettle or pot until it reaches boiling point. The hotter the water, the more effective it will kill the weeds.
- Transfer to a watering can or a heat-resistant jug works well. Ensure that the container has a spout to direct the water precisely.
- Wear gloves and eye protection to shield yourself from splashes or steam.
- Locate the weeds you want to eliminate, and slowly pour the boiling water over them. Direct the water at the base of the weeds to ensure thorough coverage.
- For stubborn or persistent weeds, you may need to repeat the process. Keep a watchful eye on the treated area, and reapply boiling water as new weeds emerge.
Salt is another alternative for weed control. It works by dehydrating the plants, so it's crucial to use salt sparingly to avoid soil salinity, as excessive salt can negatively impact the soil and surrounding plants. Sprinkling a small amount of salt directly onto weeds or in the spaces between rocks where weeds are growing is recommended.
How to use salt as a weed killer
- Sprinkle a small amount of salt directly onto the weeds or in the spaces between pavers where weeds grow.
- Avoid using too much salt, which can lead to soil salinity, affecting other nearby plants.
- Pour hot water over the salted area to dissolve the salt and help it penetrate the soil.
- Monitor the treated area and reapply salt as needed to control weed growth.
For more extreme cases of weed infestation, starting again with a cardboard weed barrier can be highly effective.
- Begin by clearing the area of existing weeds and debris.
- Choose thick, durable cardboard or layer corrugated cardboard, covering the weedy areas entirely.
- Wet the cardboard to make it pliable and encourage it to conform to the ground.
- Cover the cardboard with a layer of mulch or additional gravel for added weight and aesthetic appeal.
- Regular monitoring is essential to promptly address any signs of weeds attempting to grow through the barrier.
- Permanently banishing weeds from rocks, gravel, and stones involves a tailored approach that combines natural solutions, preventive measures, and vigilant maintenance.
