Never Bury These Things in Your Garden

While gardening is a fantastic way to enhance your outdoor space and grow your own food, there are certain items that you should never bury in your garden. Some materials can harm your plants, the soil, and the environment. In this article, we’ll explore seven things that you should avoid burying in your garden.

1. Plastic and Non-Biodegradable Materials

Plastic is one of the most harmful substances to bury in your garden. It does not decompose, and over time, it can break down into tiny microplastics that can contaminate your soil and harm your plants. Avoid burying plastic bags, containers, or any non-biodegradable materials in your garden. These materials can disrupt root growth, reduce soil aeration, and create a toxic environment for your plants.

2. Metal and Glass

Metal objects, such as cans, nails, or wire, and glass items like bottles and broken glass, should never be buried in your garden. These materials can rust or corrode, posing a risk to your plants and making your garden a hazardous place to work. Metal and glass can also leach toxic chemicals into the soil, negatively impacting soil health and plant growth.

3. Diseased Plants

If you have plants in your garden that have fallen victim to diseases, do not bury them in your garden. While you may think that burying them will help prevent the spread of disease, many pathogens can survive in the soil and infect future plantings. It’s better to remove and dispose of diseased plants in a way that ensures they won’t reenter your garden ecosystem.

4. Weeds with Mature Seeds

Burying weeds with mature seeds is a recipe for trouble. The seeds can remain viable in the soil and continue to grow, making your weed problem worse. Instead of burying these weeds, dispose of them in a way that prevents seed dispersal, such as placing them in a compost pile that reaches high temperatures to kill the seeds or bagging them for disposal.

5. Pet Waste

Pet waste, whether from dogs, cats, or other animals, should not be buried in your garden. It can contain harmful pathogens that can contaminate your soil and potentially be transmitted to you or your plants. Properly dispose of pet waste by bagging it and putting it in the trash, or consider composting it separately in designated pet waste composting systems.

6. Lime and Other Soil Amendments

While lime is sometimes used to adjust soil pH, it’s important to apply it on the surface and not bury it deeply in the soil. Burying lime can lead to localized high pH levels in the soil, which can harm plant roots and create an imbalance in nutrient availability. Follow recommended guidelines for the application of soil amendments and avoid overuse.

7. Household Chemicals

Household chemicals, including pesticides, herbicides, and cleaning products, should never be buried in your garden. These chemicals can leach into the soil and groundwater, posing a risk to plants, animals, and human health. Properly dispose of these chemicals through your local hazardous waste disposal programs.

It’s essential to take a responsible and environmentally friendly approach to managing waste and maintaining the health of your garden. Instead of burying these items, consider alternative disposal methods:

  • Recycle: Check local recycling programs for plastic, metal, and glass items.
  • Compost: Organic matter, such as kitchen scraps and yard waste, can be composted to create nutrient-rich soil conditioner.
  • Dispose Properly: Use designated disposal methods for pet waste, diseased plants, and hazardous materials.
  • Reuse: Get creative and repurpose items you no longer need instead of burying them.
