10 Unexpected Things You Should Bury in Your Garden

When it comes to gardening, most people think of planting seeds, fertilizing, and watering. But did you know that burying certain unexpected items in your garden can boost soil health, deter pests, enrich nutrients, and improve plant growth? From kitchen scraps to natural additives, some everyday items can transform your garden into a thriving, sustainable ecosystem.

This guide explores 10 unexpected things you should bury in your garden, explaining the benefits, the best methods of use, and tips to maximize their effects.

1. Eggshells: Nature’s Calcium Boost

Eggshells are not just waste—they are packed with calcium carbonate, a mineral that helps prevent blossom-end rot in tomatoes, peppers, and eggplants.

How to Use:

• Rinse and dry eggshells to remove any egg residue

• Crush them into small pieces or powder

• Bury them around the base of plants or mix them into soil

Benefits:

• Slowly releases calcium and trace minerals into the soil

• Improves soil structure over time

• Acts as a mild pest deterrent for slugs and snails

Tip: Using mesh bags or lightly crushing the shells increases the surface area, speeding up nutrient release.

2. Coffee Grounds: Fertilizer and Pest Control

Used coffee grounds are an excellent addition to your garden. They are rich in nitrogen and trace minerals.

How to Use:

• Sprinkle grounds directly into soil or compost pile

• Mix with water to make a liquid fertilizer

• Bury in planting holes to improve nutrient availability

Benefits:

• Adds nitrogen to fuel leafy growth

• Improves soil drainage and texture

• Can help repel pests like slugs and ants

Tip: Avoid excessive use, as too much can acidify the soil.

3. Banana Peels: Potassium and Phosphorus Boost

Banana peels are a natural source of potassium, phosphorus, and magnesium, essential for flowering and fruiting plants.

How to Use:

• Chop or mash peels before burying near the root zone

• Can also be blended into a slurry and poured into soil

• Composting peels is another way to release nutrients gradually

Benefits:

• Encourages blooms and fruit development

• Adds organic matter to improve soil health

• Supports microbial activity in soil

Tip: Bury the peels a few inches deep to prevent fruit flies or mold.

4. Wood Ash: Natural Liming Agent

If you burn wood in a fireplace, don’t throw away the ashes. Wood ash contains calcium, potassium, and trace minerals.

How to Use:

• Sprinkle a thin layer over acidic soils

• Mix into planting holes before transplanting

• Avoid overuse to prevent overly alkaline soil

Benefits:

• Reduces soil acidity

• Adds essential minerals

• Can deter some pests, including slugs

Tip: Only use ash from untreated, natural wood. Avoid ashes from painted or chemical-treated wood.

5. Shredded Newspaper or Cardboard

Paper products are excellent for composting, but they also directly improve soil structure when buried.

How to Use:

• Tear into small pieces and bury under a thin layer of soil

• Use around perennials or in garden beds as a mulch layer

Benefits:

• Helps retain moisture

• Adds carbon to balance nitrogen-rich materials in compost

• Suppresses weeds

Tip: Avoid glossy or heavily inked papers, which may contain chemicals.

---

6. Cheese Rinds: Protein and Minerals

Cheese rinds, especially hard cheeses like Parmesan, can slowly break down in soil, adding protein and calcium.

How to Use:

• Cut into small pieces and bury in soil or compost

• Place near vegetable roots for slow nutrient release

Benefits:

• Adds nitrogen and calcium

• Encourages microbial activity

• Breaks down slowly for long-term soil enrichment

Tip: Avoid soft or moldy cheeses to prevent attracting pests.

7. Crushed Eggs or Shells with Herb Scraps

Combining eggshells with leftover herb stems or peels creates a nutrient-rich blend for your garden.

How to Use:

• Chop herbs and crush shells

• Bury near root zones or mix with soil for seedlings

Benefits:

• Boosts soil fertility

• Supports healthy microbial life

• Acts as a natural pest deterrent

Tip: Rotate buried materials to avoid concentrating nutrients in one spot.

---

8. Bones: Natural Phosphate Source

Animal bones, such as from cooked meat (without seasoning), can provide phosphorus and calcium to garden soil.

How to Use:

• Grind or crush bones before burying

• Place near root zones for slow nutrient release

• Compost first if possible for faster breakdown

Benefits:

• Phosphorus supports root and flower development

• Calcium strengthens plants

• Slowly breaks down for long-term fertility

Tip: Avoid burying raw meat bones to prevent attracting pests.

---

9. Seaweed or Kelp

If you live near the ocean or can source kelp or seaweed, these are excellent for minerals and growth hormones.

How to Use:

• Chop fresh seaweed and bury in soil

• Rinse salt if necessary to avoid over-salting

• Can also be added to compost piles

Benefits:

• Provides trace minerals such as iodine, magnesium, and potassium

• Supports root growth and plant immunity

• Enhances microbial activity

Tip: Use sparingly to prevent soil salinity issues.

---

10. Rotten Fruit and Vegetable Scraps

Kitchen scraps that are overripe or spoiled are perfect for burying directly in garden beds.

How to Use:

• Chop into small pieces to speed decomposition

• Bury 4–6 inches deep to prevent odors or pests

• Mix with soil or compost for gradual nutrient release

Benefits:

• Adds nitrogen, potassium, and other micronutrients

• Supports soil microbes and worms

• Improves soil organic content and texture

Tip: Avoid burying large amounts in one place to prevent fruit flies or mold accumulation.

Safety Tips for Burying Unexpected Items

1. Avoid toxic or chemically treated materials – nothing painted, plastic-coated, or chemically processed.

2. Chop or crush items when possible – speeds decomposition and nutrient release.

3. Bury at appropriate depth – 3–6 inches is usually sufficient.

4. Rotate materials – prevents nutrient overload in one area.

5. Use in combination with composting – accelerates breakdown and reduces pests.

Benefits of Burying Unexpected Items

Burying these items offers numerous advantages:

• Soil enrichment: Slowly releases nutrients and improves fertility

• Pest management: Some items naturally repel insects or slugs

• Sustainability: Reduces household waste

• Microbial health: Supports worms, fungi, and beneficial bacteria

• Plant growth: Encourages stronger roots, better flowering, and increased yield

By repurposing household waste and natural materials, your garden becomes self-sustaining, productive, and environmentally friendly.

Conclusion

Your garden can benefit from more than just seeds and fertilizer. Items you might otherwise throw away—eggshells, coffee grounds, banana peels, bones, seaweed, and even newspaper—can be buried to improve soil structure, provide essential nutrients, and support plant and microbial health.

By understanding what to bury, how to prepare it, and where to place it, gardeners can maximize growth, reduce waste, and create thriving, resilient gardens. Next time you clean out your kitchen or compost bin, think twice before tossing those scraps—they may just be the secret to your best garden yet.
