Should Metal Raised Garden Beds Have Bottoms?

Should Metal Raised Garden Beds Have Bottoms? - VEGEGA Metal Raised Garden Bed
If you have a raised bed planter, will you equip it with a bottom? Generally, garden beds do not need a bottom. The garden beds that are generally sold do not have a bottom. If you need extra, you need to find another material for the bottom. A major feature of the corrugated metal garden bed is that it 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.

The first is drainage performance. Since raised bed planters or raised garden 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.

To improve drainage performance, we could consider placing rocks at the bottom of the garden bed, especially in 32-inch garden beds or where the drainage system on the ground is poor. Placing crushed rock or gravel at the bottom of a raised bed will work well in improving drainage and air circulation. 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.

The second is durability. If the bottom of the raised bed planter is in direct contact with the soil, over time, the microorganisms in the soil can easily cause the bottom to rust or even crack. The bottomless corrugated metal raised garden 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.

Generally, we use a variety of organic materials, such as wood, leaves, cardboard, etc., to fill garden beds bottom. If the bottom is closed, various materials are piled up together, and the capacity is relatively small. The bottomless beds can make the organic material directly contact the ground, and the overall space is larger.

Although raised bed planters with bottoms are easy to move and effectively prevent insects, they also have many disadvantages, especially in terms of drainage performance. If we water too much, we also have no way of getting the excess water out.

Furthermore, in the case of the closed type, the permeability of the soil becomes poor. Because the air cannot be circulated smoothly, it is very likely that the microorganisms in the soil will be inactivated.

We all know that the roots of a plant need oxygen the most, so we can't provide a closed space for the plant. In the long run, the air will not circulate and the plants grown will not be healthy.
