The cons of raised beds

The soil mix also can be a significant, albeit one-time, expense. Raised beds need water more often since the soil is more exposed to air and dries quicker. Similar to growing in containers, the extra watering can leach nutrients out of the soil quicker than in-ground gardens.

On average, a DIY raised bed constructed from wood will cost $25 to $50 per square foot. To have a wooden raised bed constructed and installed for you, budget for at least $100 per square foot. (Find a kitchen garden company in your area.)

To start, lay down sheets of cardboard or newspaper for weed suppression and then fill the raised bed structure halfway up with alternating layers of nitrogen-rich materials (like kitchen scraps and grass clippings) and carbon-rich materials (like wood chips and dried autumn leaves).

While generally minor, raised beds do have some disadvantages. Raised beds dry out faster than level garden sites. Accordingly, they have to be watered more frequently in dry weather. Initial construction of the raised bed may take more effort than maintenance of the conventional garden.

To put it simply, you should put a layer of organic material at the bottom of your garden bed, which will break down and enrich the soil. This can include compost, or woody material such as logs, dry wood, branches, and leaves.

A depth of 8 – 12 inches will suffice for most gardening situations. Because of the excellent drainage properties of raised beds, it is possible to grow an abundance of vegetables in a limited amount of space.

The soil in your raised beds will break down over time; however, you don't need to replace all of the soil in your raised bed garden to have beautiful, vibrant, or bountiful plants. Before planting the following growing season, add Miracle-Gro® Refresh™ Soil Revitalizer to your old soil, following package directions.

Soil taken from your yard or a garden bed is too dense to use in a pot or raised bed. Instead, for containers, you'll want to use potting mix (also called potting soil), a lightweight and fluffy alternative. For raised beds, you'll want to use a blend of potting mix and garden soil.

It acts as a physical barrier to block out pernicious weeds. Usually, 2 – 3 layers of cardboard will suffice, though you may want layers in more weed-prone areas. The damp environment created by the cardboard is conducive to earthworms and other beneficial soil microorganisms.

Should I put wood chips in the bottom of my raised garden bed? ›

Fresh wood chips can draw a lot of nitrogen from the soil, which can make the soil unideal for your vegetable plants. Wood chips will also break down pretty quickly (faster than sticks) and will cause the soil level in your raised beds to sink unevenly, all while increasing the temperature of your raised bed.

Raised beds work best when you fill them with plants that need the same amount of water to grow. If you try pairing a thirsty tomato with a dry soil-loving agave, for example, one of them will suffer. Moisture-loving plants that do well in raised garden beds include cardinal flowers, sedges, and monkshood.

As a general rule, put tall veggies toward the back of the bed, mid-sized ones in the middle, and smaller plants in the front or as a border. Consider adding pollinator plants to attract beneficial insects that can not only help you get a better harvest, but will also prey on garden pests.

Metal garden beds are better than wooden raised garden beds in terms of durability, longevity and pest prevention. However, wooden raised garden beds are more affordable and easier to customize.

Comparing raised beds and in-ground gardens, it's important to consider their respective advantages. Raised beds offer better soil structure and drainage, which can help grow plants more effectively. They also provide an opportunity to amend the soil with organic matter, improving its fertility and nutrient content.

Untreated wood: Cedar and redwood are popular choices because they naturally resist rot and insects, and they do not need chemical treatments that could potentially harm your plants.
