The first is drainage performance. Since raised flower beds or raised garden beds are in direct contact with the ground, they need good drainage. The bottomless design of the elevated flower bed can effectively prevent the root system from being oversaturated and rotted due to excessive water, and can also avoid the phenomenon of insufficient water and dry root system. Another advantage is that the roots readily absorb oxygen for healthy growth.
To improve drainage, consider placing stones at the bottom of the beds, especially in 32-inch beds or areas where the ground does not drain well. Placing gravel or gravel in the bottom of the raised bed will help improve drainage and air circulation. Over time, the soil settles and becomes compacted, and the rocks at the bottom of the bed provide space for excess water to drain from the plant roots.
The second is durability. If the bottom of the raised flower pot is in direct contact with the soil, microorganisms in the soil can easily cause the bottom to rust or even crack over time. The Bottomless Corrugated Metal Raised Garden Bed is finished with a high-quality waterproof and anti-rust coating, which not only resists wind and rain, but also means that you don't have to worry about rust.
What's more, there is more space in the bottomless raised bed planter. In the state where the bottom is closed, the capacity is relatively small and it will be relatively closed.
Usually, we use various organic materials such as wood, leaves, cardboard, etc. to fill the bottom of the flower bed. If the bottom is closed and various materials are piled together, the capacity is relatively small. The bottomless bed allows the organic matter to directly contact the ground and the overall space is larger.
Although the bottomed raised bed flowerpots are easy to move and have good insect repelling effect, they also have many disadvantages, especially in terms of drainage performance. If we water too much, we also cannot drain the excess water.
In addition, in the case of the closed type, the permeability of the soil becomes poor. Microorganisms in the soil are most likely to be inactivated due to poor air circulation.
We all know that the roots of plants need oxygen the most, so plants cannot be given a closed space. If things go on like this, the air will not circulate and the plants will be unhealthy.
