How To Construct An Elevated Garden Bed?

Raised garden beds, also known as planter boxes, are a great choice for growing food at home. They are fun, useful, healthy, and beautiful additions to any yard. To build a raised garden bed, dig out a shallow trench and mark out the shape using canes and string. To prepare your site, dig out a shallow trench and use a shovel to select an area with great sunlight. Purchase two 2″ x 6″ x 8″ boards and cut each board in half for a total of four 4′ boards. Use 4″ framing.

Build a simple raised bed from scratch with basic carpentry skills. Several builders recommend adding a few cross boards on the bottom and attaching quarter-inch hardware cloth to the bottom. Start with supports on the sides using scrap 2×4 pieces. Attach two or three to each of the long sides and one to the short sides.

What is the best way to build a raised garden bed?

This guide provides a step-by-step guide on how to build a raised garden bed using minimal tools. The author, a gardener by trade, created a simple method for constructing a wooden raised bed using minimal tools. The guide outlines the steps to create a beautiful, long-lasting raised garden bed using the original $100 cost of cedar boards, framing angles, and hardware. However, the price of cedar has increased, so the total budget should be slightly over $100.

The guide also includes instructions on how to begin other sides of the wooden raised bed and complete the first raised bed corner. The author’s favorite way to build an inexpensive raised bed is by following these steps and using any suggested modifications.

How deep should raised garden beds be?

Vegetable beds should be 12-18 inches deep to accommodate plant roots, especially if placed on cement or patios. These beds are suitable for cultivating a variety of vegetables, including those with deep root systems. Deeper beds also allow for more moisture retention, reducing watering and drying out. Common garden plants include garlic, onions, chives, lettuce, corn, cabbage, radishes, strawberries, beans, peas, cantaloupes, squash, eggplants, carrots, turnips, beets, and potatoes. These beds are ideal for a variety of vegetables, including those with deep root systems.

What are the layers of a raised garden bed?

The selection of the right soil mix is crucial for successful vegetable cultivation in a raised garden bed. The ideal mix should balance drainage, aeration, and nutrient content. A recommended approach is to layer the bed with coarse materials like gravel, garden soil and garden matter, compost or well-rotted manure, and high-quality topsoil. This creates a fertile ground for vegetables to thrive. A high-quality raised bed soil mix supports healthy plant growth, promotes water retention, and effective weed management.

Compost should be well-rotted to prevent harm to plant roots and should be layered with other organic matter to enhance nutrient diversity. Mulch, applied on top of the soil, insulates the soil, inhibits weed growth, and releases nutrients into the topsoil over time. Avoid placing mulch directly against plant stems to prevent moisture trapping and pest or disease growth.

Which vegetables grow best in raised beds?

Vegetable roots vary in depth and size, with heat-loving vegetables having deeper, more extensive systems. Examples include pumpkins, winter squash, watermelons, tomatoes, artichokes, okra, and sweet potatoes. Root vegetables like carrots, onions, and garlic grow best in loose, partially sandy soil, making them ideal for raised beds. Compact varieties, such as bush-type summer and winter squashes, can easily overgrow a raised bed. For cucumbers, grow on a trellis to save space.

For tomatoes, choose patio varieties like Sprite and Tumbling Tom, as bush-type determinate tomatoes work better in small spaces. If raised beds are taller than the common 10- to 12-inch height, choose bush beans instead of tall pole beans, or use a ladder for picking.

What should you not put in a raised bed?

Raised beds are ideal for growing a wide variety of edible plants, but not all plants can or should be grown in them. Some plants grow too large for raised beds, such as potatoes, asparagus, artichokes, rhubarb, corn, wheat, rice, and winter squash. Raised beds can be challenging to maintain due to the need for ladders, which can be dangerous for harvesting plants. It is essential to consider the specific needs of each plant when choosing a raised bed, as not all plants can thrive in raised beds. Therefore, it is essential to carefully consider the type of plant and the space available for each plant to ensure the best growth and care.

What do you put on the bottom of a raised garden bed?

Cardboard or newspaper can be used to line the bottom of raised garden beds to deter pests and weeds on a budget. Choose cardboard with minimal markings and no tape for a safer option. Stainless steel gopher nets can be used for extra protection, as seen in Vego Garden’s modular cover system. Landscaping fabric can prevent soil erosion, promote water retention, and keep out invasive grasses. While it doesn’t break down over time like cardboard, it limits shallow-rooted plant growth, earthworm movement, and soil mixing. Deeper beds may not need it unless a weed problem is present.

Are raised beds better than ground?

Raised beds offer better drainage than in-ground gardens, as they provide faster watering for edible plants like cabbages, radishes, kale, and peas. In-ground gardens are more susceptible to waterlogged roots, causing mold, rot, and mildew. Raised beds, with their elevation, facilitate faster draining, especially in wet climates like Houston, Texas. Raised beds also protect plants during heavy rains.

When setting up an in-ground garden, choose plants that thrive in wet or dry conditions, depending on your climate. Raised beds are particularly beneficial for kitchen gardens, as they help maintain the health of the roots and prevent the growth of mold, rot, and mildew.

Do raised beds need to be on soil?

Raised beds can be built on hard surfaces, but they require adjustments to ensure good drainage and avoid waterlogging. For timber beds, drill holes in the sides to allow excess water to drain away. For stone or brick beds, leave gaps at 45cm intervals between the joints to act as drainage holes. Cover these with fine wire mesh and heap gravel against the mesh when filling the bed. Fill the beds with a mixture of organic matter, sharp sand, and topsoil, and be prepared to refresh and replace the soil regularly.

Plants in raised beds tend to suffer more from drought due to improved drainage, so it’s important to monitor watering needs. Regularly check the moisture level below the soil surface and adjust watering accordingly during warm and windy weather.

Should I put fabric on bottom of raised garden bed?

Landscape fabric serves as a raised bed liner to prevent soil erosion and minimize nutrient loss risk. It helps maintain water-soluble nutrients from the soil, preventing water from gushing out too quickly. To make installation easier, you can buy materials separately or use bundles like the landscape fabric and heavy-duty staple bundle, which includes 3″ x 50″ weed barrier landscape fabric with 8 or 11 gauge staples. This makes building a raised bed garden more efficient and cost-effective.

What do you line inside a raised garden bed?

Wide-mesh hardware cloth, stainless steel mesh, landscape fabric, burlap sack, or newspaper/cardboard can be used to line the bottom of raised garden beds. These materials keep weeds and burrowing animals out, but allow earthworms to pass through. Earthworms are nature’s gardeners, aerating and enriching soil for plants. Staple the cloth to the bed frame during construction and ensure it remains in place for years to come. This durable material is designed to prevent burrowing animals from affecting the bed frame’s functionality.
