Raised bed gardens are not always the better option.Depending on your location, raised beds could be your best option if you live in a wet and rainy environment or have very poor and compact soil.
You can use in-ground soil to fill up a raised bed, but only in rare circumstances, if and only if the native soil in your yard is close to being perfect.
Before setting up a garden, it is important to conduct a small survey of your desired garden area and weigh out the options of whether to choose a raised garden bed or an in-ground garden.
