1. Leafy Greens and Herbs: 6 to 12 Inches Deep

If your green thumb leans toward cultivating leafy greens like lettuce, spinach, or various herbs, a shallower raised garden bed is the way to go. These plants don’t require a lot of root space, so a depth of 6 to 12 inches should suffice. A shallower bed conserves resources like soil and water while promoting healthy growth.

2. Root Crops: 12 Inches Deep

For root vegetables such as carrots, radishes, and beets, you’ll want a slightly deeper raised garden bed. A depth of 12 inches provides ample room for these crops to develop underground. This depth allows their roots to grow unhindered, resulting in plump and flavorful harvests.

When it comes to fruiting plants like strawberries or bush beans, opt for a raised bed with a depth of 12 to 18 inches. These plants have more extensive root systems and benefit from the additional space. Deeper beds also offer better stability for taller fruit-bearing varieties.

4. Tomatoes, Cucumbers, Squash, Zucchini, and Kale: 18 Inches Deep

Some plants, like tomatoes, cucumbers, squash, zucchini, and kale, have voracious root systems and substantial top growth. To accommodate these hungry plants adequately, a raised bed with a depth of 18 inches is ideal. This depth ensures that their roots have enough room to access nutrients and water, resulting in bountiful harvests.
