Do Metal Raised Garden Beds Need A Bottom?

Do Metal Raised Garden Beds Need A Bottom
If you have a raised bed planter, will you equip it with a bottom? Generally, raised garden beds don't need a bottom. The raised beds that are generally sold do not have a bottom. If you need extra bottom for your balcony, you may need to find another material for the bottom. A major feature of the metal raised garden beds has no bottom, which effectively maintains the permeability of the soil, prevents pests and diseases, and also provides more space for plant roots to stretch.

Benefits for raised beds without a bottom

Good drainage performance

Since raised beds are in direct contact with the ground, good drainage is necessary. The bottomless design of the raised garden bed can effectively prevent the roots from being too saturated and rotting due to too much water, and also avoid the phenomenon of insufficient water and dry roots. And another advantage is that the roots could easily absorb oxygen for their healthy growth.

Placing rocks or gravel at the bottom of the garden bed can improve the drainage performance and air circulation in garden beds. Because soil settles over time and becomes compacted, the rock at the bottom of the bed provides space for excess water to drain away from plant roots.

Durable in use

The second is durability. If the raised garden bed with bottom is in direct contact with the soil, over time, the microorganisms in the soil can easily cause the bottom to rust or even crack. Vegega bottomless raised bed adopts a high-quality waterproof and antirust coating, which means it can not only withstand wind and rain, but also means you don't need to worry about rusting.

What's more, there's more room for bottomless raised bed planters. In the state where the bottom is closed, the capacity is relatively small, and it will be more confined.

Benefits for raised garden beds with a bottom

  1. Pest control: The bottom barrier can be a physical barrier against burrowing pests like gophers, moles, and slugs.
  2. Convenience: Raised garden bed with bottom can be placed on any surface. Include concrete, or patios, enabling gardening where traditional in-ground planting isn't possible.
  3. Prevention of soil erosion: The sides of the garden bed help prevent soil erosion, especially in sloped areas or during heavy rain.


Raised garden bed with bottom is easy to move and effectively prevent insects. But they also have some disadvantages, especially in terms of drainage performance. If we water too much, we also have no way of getting the excess water out. But we could choose our raised beds based on our environment and needs.
