5 Natural Methods to Effectively Remove Weeds from Your Gravel

Ethan Miller

Gravel driveways and landscaping add a touch of rustic charm to any property. However, the tiny spaces between gravel stones create perfect environments for dreaded weeds to grow if left unchecked. Though there are many chemically-treated options available in the market, adopting eco-friendly alternatives is kinder to the environment, prevents water contamination, and avoids harm to non-targeted plants and animals.

The following five natural ways will help you eliminate these pesky plants from your gravel areas while preserving the environment and maintaining the aesthetics of your house.

1. Corn Gluten Meal: A Natural Pre-emergent Herbicide

Corn gluten meal acts as an effective pre-emergent weed control method in gravel driveways or other unwanted growth areas. This byproduct of corn processing inhibits seeds from germinating, thus preventing further weed invasion.

How to use corn gluten meal:

  • Apply it uniformly on the gravel surface before the growing season starts (e.g., during spring).
  • The general application rate is around 20 pounds per 1000 square feet.
  • Make sure the area remains undisturbed for at least one week after applying the meal; soil disturbance can reduce its effectiveness.
  • As corn gluten meal may also suppress desirable species’ seedlings, refrain from using it in locations where reseeding is being conducted.

2. Solarization: Harnessing the Power of Sunlight

Solarization is a process that capitalizes on solar energy to destroy weed seeds and pathogens beneath the ground’s surface. It is suitable for widespread weed growth in sunniest areas of your gravel landscape.

Steps to perform solarization:

  1. Prepare the target area by pulling out any visible weeds and compressing the gravel surface (consider using a roller or tamper).
  2. Moisten the area with water to increase soil temperature, as moist soil will conduct more heat than dry soil.
  3. Lay clear plastic sheeting on top of the affected area, ensuring it covers every corner where weeds are present.
  4. Anchor the sheet edges with heavy rocks, bricks, or sandbags to prevent winds from lifting the plastic off the ground.
  5. Leave the cover on for about four to six weeks during the hottest months of summer for maximum effectiveness.
  6. At the end of the solarization period, remove the plastic sheets carefully to avoid contaminating the now weed-free zone with new seeds.

3. Natural DIY Sprays: Vinegar and Soap

A mixture of common household items like distilled vinegar and dish soap offers an economical and eco-safe pest control solution that helps you keep weeds at bay.

How to create an effective DIY herbicidal spray:

  • Mix one gallon of white vinegar with two cups of table salt and one teaspoon of mild liquid dish soap in a large container.
  • Stir the solution well until all salt has dissolved.
  • Pour the mixture into a sprayer and apply directly onto unwanted vegetation—taking care not to spray desired plants, as this concoction is non-selective and may harm them too.
  • Apply the solution on sunny days for faster evaporation and optimum results.

4. Boiling Water: A Quick and Accessible Solution

Pouring boiling water directly onto weeds growing between gravel stones can effectively kill them within a short time. The extreme heat scalds the plants’ cells, disrupting their internal structure and causing them to perish quickly.

Tips for using boiling water as a weed killer:

  • Heat a large pot of water until it reaches its boiling point.
  • Carefully pour the boiling water over the target weeds, ensuring even coverage.
  • Allow one or two days for affected plants to wither before removing the dead vegetation by hand or using a rake.
  • Repeat the process if required for stubborn weeds.

5. Flame Weeding: Controlled Heat for Weed Management

Flame weeding involves using specialized torches to burn weeds at high temperatures. It is an effective way to remove not only existing weeds but also prevent the germination of new ones since the intense heat kills seeds in the soil.

Guidelines for safe flame weeding:

  • Select a propane-fueled flamer designed specifically for weed control from gardening stores or online marketplaces.
  • Follow all safety precautions indicated in the user manual, such as wearing appropriate protective gear and maintaining equipment per guidelines.
  • Start the flame weeder according to the manufacturer’s instructions, then direct the flame on the undesired vegetation until wilting or discoloration occurs—but do not incinerate the weeds to reduce the risk of fires.
  • Be vigilant about fire hazards during dry weather conditions and always have appropriate firefighting equipment on hand in case of emergencies.

By adopting these eco-friendly strategies, you can efficiently remove undesired weeds from your gravel areas without causing harm to the environment or yourselves. Try out different methods and find the one best suited for your specific needs—keeping in mind that prevention through regular maintenance is ultimately key to long-term weed management.
