How deep should my raised garden bed be to grow herbs and vegetables?

Herbs generally have shallow root systems, so a raised garden bed that is 6-12 inches deep should be sufficient for growing most herbs. Some larger herbs, such as rosemary or thyme, may require a deeper bed, so you may want to consider a bed that is at least 12 inches deep if you are planning to grow these types of herbs.

Some vegetables, such as carrots and radishes, have deep root systems and may require a raised garden bed that is at least 12 inches deep. Other vegetables, such as tomatoes and peppers, have shallower root systems and may be able to grow in a bed that is 6-12 inches deep.

It's important to keep in mind that the depth of your raised garden bed will also depend on the type of soil you are using and the drainage it provides. If you are using a soil mix that is high in organic matter, such as compost, it may be able to hold onto moisture longer, so a shallower bed may be sufficient. However, if you are using a soil mix that drains quickly, you may want to consider a deeper bed to help retain moisture and prevent your herbs from drying out.

Overall, the depth of your raised garden bed should be based on the specific needs of the herbs you are growing and the conditions in your garden.
