What are the disadvantages of raised garden beds?
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. Unlike in-ground gardens, raised beds allow you to build a raised bed frame and fill it with high-quality soil, ensuring optimal conditions for plant growth. Additionally, raised beds are easier to manage, as they require less bending and kneeling, making it more accessible for people with mobility issues.The main difference between raised beds and planters is based on the presence of a base plate, the way they are modularized and the design will be the same. Raised beds are traditionally without a bottom plate, they are designed to be placed directly on the soil.
What is the safest material for a raised garden bed?
So what is the safest material for raised garden beds? I think we can comfortably say, we LOVE CEDAR! Cedar is hands down the best material for raised garden beds.

This means if you have a 10 inch (25 cm) plant, all but the top 3 to 4 inches (8-10 cm) should be under soil.Your soil should be at minimum 6 inches deep and preferably 10 inches or more.
