Is it OK to use potting soil for raised beds?

Raised beds provide ideal soil conditions for gardeners, whether deep or shallow. A 50:50 blend of potting mix and Miracle-Gro® All Purpose Garden Soil is ideal for these beds. Top-quality potting mix and raised bed soil are more expensive but provide better results. Poor quality mixes and soils can be heavy, dense, and poor-draining, making them difficult for roots to thrive. To keep plants happy, start nourishing them a month after planting with Miracle-Gro® Shake ‘n Feed® All Purpose Plant Food. Follow label directions for optimal plant growth.

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.

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.

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 does a raised bed need to be for a garden?

The depth of a raised bed is crucial for its effectiveness, whether it’s a perennial border garden or a metal raised bed in a vegetable garden. A minimum depth of 8-12 inches is necessary for plant root systems to grow healthy. Raised beds have excellent drainage properties, allowing for an abundance of vegetables in limited space. If drainage is an issue or plants prefer drier soil, the depth can be increased to accommodate a porous growing medium.

The material used for a raised bed should be durable, attractive, and stable, ensuring it blends well with the landscape. The sides of the bed provide structural support and help contain soil in a specific space. Materials like metal panels, wood, or brick and stone can be used for raised garden beds. When selecting a raised bed design, it’s essential to consider both the depth and material of the bed.

Should raised garden beds have bottoms?

Raised beds typically have no bottom, except for those placed on surfaces like wooden patio decks, balconies, porches, or concrete walkways. Most online raised bed kits and instructions do not have bottoms. Four-sided beds, like those shown, are designed for optimal drainage and should be set on gravel, grass, or mulch, filled with good soil. This ensures that the bed does not turn into a bathtub, which is ideal for herbs and veggies that prefer a good soak but do not want their roots to sit in water too long. Most raised bed kits and instructions do not include bottoms.

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.

Why do you put cardboard under a raised bed?

Earthworms thrive in a damp environment created by cardboard, which can be used in raised beds and vermicomposting bins. To repurpose surplus cardboard, line it on the bottom of raised garden beds to block out weeds and act as a barrier against rhizomatous, weedy, or invasive plants. Using dye-free or recyclable cardboard can help mitigate concerns about chemicals and glue compounds leaching into the soil. An organic stamp is a good indicator of its safety.

Plain cardboard with no tape and minimal markings is best for best results. Cardboard with glossy coatings or inks should be avoided. Most cardboard found around the house is safe to use. Using dye-free or recyclable cardboard can help reduce the amount of chemical substances in the soil.

What vegetables grow best in raised garden beds?

Raised beds are ideal for vegetables that require a minimum soil temperature of 60°F (15°C) for seed germination. They are exposed to air and sunlight, warming up faster than garden soil. They work as season extenders in spring, allowing planting earlier than in garden beds. However, in summer heat, the soil in raised beds dries out quicker, requiring more watering. Mulching can help counter this, but a raised bed in full sun still gets baked. In hot, arid climates, sunken beds are the opposite of raised beds, improving water retention and evaporation while keeping the soil cooler.

What should you not grow in a raised bed?

Raised garden beds can be a helpful solution for home gardeners, but not all plants are suitable for them. Some plants, such as squash, melon, corn, blackberries, mint, apple trees, asparagus, and pumpkins, require more space for their roots to spread out due to their sprawling vines or complex root systems. Raised beds can help incorporate the right soil for your plants and extend the amount of garden space, but not all plants will thrive in a raised bed.

Horticulturalists and arborists have provided more information on which plants should never grow in a raised bed. Some plants, such as squash, melon, corn, blackberries, mint, apple trees, asparagus, and pumpkins, are better off directly in the ground.

What is best to line 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.
