What is the meaning of raised bed?
Raised beds and container gardens refer to improved areas of soil elevated above ground level where plants can grow. A minimum height for raised garden beds of approximately 24-inches offers the best of both worlds – accommodating the diverse root depths of various plants while remaining manageable and cost-effective.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.Elevated garden beds typically offer superior drainage and soil aeration compared to traditional ground-level beds. The raised platform allows excess water to drain more efficiently, preventing waterlogging and root rot.Filling your raised bed completely with nutrient-rich soil and compost gives plants the full depth to root, ensures healthy growth, and maximizes productivity. Use a weed barrier or cardboard at the bottom to prevent weeds and stop soil from washing out.
What is the best use of raised beds?
The only time where raised beds are really needed is where the garden soil is waterlogged. By lifting the soil above ground level it will drain and that’s great for permanent crops (such as rhubarb and asparagus) that would otherwise rot in the winter wet.

Raised beds can cost more to establish – Beds that are constructed of quality materials, such as cedar wood, can last for decades, but the initial cash layout to build the beds can be a little high.Most raised beds are constructed from lumber. Pine and other framing lumber will last about 4 to 5 years, while more expensive cedar will hang together for 8 to 10 years. Don’t use redwood, which is an endangered species.
What do you put in the bottom of a raised bed?
Add a physical barrier like burlap or weed barrier cloth to the bottom of your bed before you shovel in the soil. You could even use several layers of cardboard as a weed barrier. Just make sure to remove tape and any areas with glossy print first. The cardboard will break down in about 4 to 6 months. You Can Use a Layer of Cardboard at the Bottom of Raised Beds to Prevent Weeds. If your budget doesn’t allow for weed barrier cloth, you can add several layers of cardboard to the bottom of your raised bed before filling it with soil. The cardboard will decompose in about 4 to 6 months.You don’t really need a bottom unless your raised bed will sit on a surface you’d like to protect such as a wooden patio deck, a balcony, a porch, a concrete walkway, etc. Standing planters also, obviously, have bottoms so that they can hold the contents of the garden several feet above the ground.Filling your raised bed completely with nutrient-rich soil and compost gives plants the full depth to root, ensures healthy growth, and maximizes productivity.

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.When adapting raised garden beds for accessibility, such as for wheelchair users or individuals with limited mobility, it’s important to consider factors like height, width and access paths.
