What Is an Above Ground Garden?

An above ground garden, often referred to as a raised bed garden, is a gardening method where soil is placed above the natural ground level inside a contained structure. Unlike traditional in-ground gardens, above ground gardens provide better soil quality and drainage, making them ideal for urban environments, rocky terrain, or areas with poor soil.

Why Build an Above Ground Garden?

Building an above ground garden has multiple advantages, including:

Improved soil quality: You control the soil mix, ensuring it’s nutrient-rich and well-draining.
Better drainage: Excess water drains easily, preventing root rot.
Weed control: Elevated beds reduce weed intrusion and make maintenance easier.
Accessibility: Easier on the back and knees, perfect for those with mobility issues.
Extended growing season: Soil warms up faster in spring, allowing earlier planting.

Step 1: Planning Your Above Ground Garden

Choose the Location

Sunlight: Select a spot that receives at least 6-8 hours of direct sunlight daily.
Accessibility: Ensure easy access for watering, planting, and maintenance.
Level ground: Choose a flat area to prevent soil erosion and water pooling.

Decide on the Size and Shape

Typical raised beds are 4 feet wide (for easy reach across) and can be any length.
Common heights range from 6 inches to 24 inches, depending on your needs.
Shapes can vary: rectangular, square, or even circular.

Select Materials

Wood: Cedar and redwood are naturally rot-resistant and popular choices.
Recycled materials: Composite wood or repurposed bricks.
Metal: Galvanized steel beds offer durability and a modern look.
Concrete blocks: Affordable and long-lasting.

Step 2: Building Your Above Ground Garden

Materials Needed

Wood planks or chosen building material
Screws or nails
Drill or hammer
Measuring tape
Level
Landscape fabric (optional)
Soil and compost

Construction Instructions

Measure and cut your materials to the desired dimensions.
Assemble the frame: Connect the sides using screws or nails, ensuring corners are square.
Prepare the ground: Clear vegetation and level the area where the garden will sit.
Optional – Lay landscape fabric: This prevents weeds from growing up into your bed while allowing water drainage.
Place the frame on the prepared ground.
Fill the bed with soil: Use a mix of topsoil, compost, and organic matter for optimal plant growth.

Step 3: Choosing the Right Soil Mix

A high-quality soil mix is crucial. Use:

40% topsoil: Provides bulk and minerals.
40% compost: Adds nutrients and beneficial microbes.
20% coarse sand or perlite: Improves drainage and aeration.

Avoid using garden soil alone as it can compact and drain poorly.

Step 4: Planting Your Above Ground Garden

Select Suitable Plants

Vegetables: Tomatoes, lettuce, carrots, peppers, and beans thrive in raised beds.
Herbs: Basil, parsley, thyme, and rosemary grow well.
Flowers: Marigolds and nasturtiums can deter pests naturally.

Planting Tips

Follow spacing recommendations on seed packets.
Group plants with similar water and sunlight needs.
Use companion planting to boost growth and deter pests.

Step 5: Maintaining Your Above Ground Garden

Watering

Above ground gardens dry out faster; water deeply 2-3 times a week depending on weather.
Consider installing a drip irrigation system for consistent moisture.

Fertilizing

Apply organic fertilizers or compost every 4-6 weeks during the growing season.
Avoid over-fertilizing, which can harm plants.

Pest and Weed Control

Inspect plants regularly for pests.
Use natural pest deterrents like neem oil or insecticidal soap.
Hand-pull any weeds that appear.

Expert Tips for Success

Rotate crops annually to prevent soil-borne diseases.
Mulch your beds with straw or wood chips to retain moisture.
Install trellises for vining plants like cucumbers and peas.
Use row covers to protect plants from cold or pests.

Real-World Example: Urban Gardeners Thriving with Raised Beds

In a 2022 study published by the National Gardening Association, urban gardeners reported a 30% increase in vegetable yield when switching to above ground gardens due to improved soil control and pest management. Jane Smith, a community garden coordinator in Chicago, says, “Raised beds transformed our garden space, allowing us to grow fresh produce in a formerly unusable parking lot area.”

Frequently Asked Questions (FAQ)

Q: Can I build an above ground garden on a balcony?
A: Yes! Choose lightweight materials like cedar or composite, and ensure your balcony can support the weight.

Q: How deep should my raised bed be?
A: At least 6-12 inches for most vegetables; root vegetables may need 18-24 inches.

Q: Do I need to line the bottom of my raised bed?
A: It’s optional. Landscape fabric helps with weed control but is not necessary if the area below is weed-free.

Conclusion

Building an above ground garden is an accessible and rewarding way to grow your own food, regardless of space or soil constraints. By carefully planning your garden, selecting the right materials, preparing nutrient-rich soil, and maintaining your plants properly, you can enjoy a healthy, productive garden all season long. Whether you want to grow fresh herbs on your balcony or create a vegetable oasis in your backyard, an above ground garden is a smart, sustainable choice.
