Why Bottomless Raised Beds Are Your Best Choice
Vegega provides bottomless raised garden beds, and we recommend starting with a bottomless raised bed unless you have a specific reason to add one. Bottomless raised beds are great for natural drainage and root growth while keeping soil contained, even on smooth surfaces like concrete patios or wooden decks.
Key Benefits of Bottomless Raised Beds
- Better Drainage: Metal raised beds don’t absorb soil moisture like wood, preventing waterlogging, helping to maintain ideal soil moisture levels, and reducing the risk of root rot.
- Soil Security: Soil Security: Tightly fitted edges and proper filling methods keep soil in garden beds—no spills on hard surfaces like concrete or patios.
- Pest Control: Stainless steel mesh underneath blocks burrowing pests, while 17" and 32" tall raised beds serve as a strong barrier against climbers.
- Slope & Surface Adaptable: Performs flawlessly on grass, gravel, concrete, or sloped terrain.
Will Metal Raised Beds Move Over Time?
One of the most common questions is whether metal raised beds will move or shift, especially since they don't have a fixed base. However, the weight of the soil and other filler holds the garden bed firmly in place. Even on slightly sloped surfaces, the raised beds remain stable on various grounds, such as grass, cement, or wooden decks.
Will Soil Leak from Metal Raised Beds on Concrete or Decks
Our bottomless metal raised beds are designed to keep soil exactly where it belongs—inside the garden bed. With proper setup, you can prevent soil from escaping and get a water-out, soil-in garden bed. Here are the best practices for preventing soil leakage.

How Filling Methods Keep Your Raised Bed Stable
1. Lasagna Filling Method
The Lasagna filling method uses alternating green and brown organic materials, compost, and soil layers. These layers break down over time and turn into rich, loamy soil that plants adore.
2. Hugelkultur Filling Method
Hugelkultur involves filling the bottom of the garden bed with logs, branches, and other woody debris. These layers break down over time, becoming a nutrient food for beneficial microorganisms.

- Choose Permeable Liner: Line the bottom of the garden bed with materials like landscape fabric or geotextile cloth. This allows water to drain while keeping soil particles contained. View article about the liners for garden bed.
- Use a Base Layer: Placing some coarse material (gravel or small stones) at the bottom can enhance drainage and prevent soil from seeping out.
