Advantages of Raised Garden Beds

Lets look at the advantages of a raised garden bed first.

Good Quality Soil and Utilisation of Space

A garden bed is like a big empty container, and you can stuff it with top quality compost, which is super beneficial for your plants. The loose, fertile soil will allow the roots of your plants to penetrate easily, making your plants healthier. A raised garden bed can be built in a tight space, most garden beds are 3 -4 wide. A Raised Garden bed lets you work around it, and in this way, you can use the entire garden space for your plant’s growth.

Prevention of Soil Erosion 

Soil erosion can be significantly controlled using raised garden beds. Soil erosion is mainly accelerated during rainy conditions. The top layer of soil that is loose and fertile is washed away. Excessive irrigation can also cause this problem. A Raised garden bed creates a barrier to stop this loss of soil by erosion. 

Save water

One of the best advantages of using a raised garden bed is saving water. A raised garden bed can be fitted with a drip irrigation system. This will save you water and nutrients for your plants. 

Weed Control 

Weed emergence is a lot less in elevated gardens; thus, the need for using weedicides is also reduced. You might find a few weeds every now and then but it wont be a struggle to pluck them out by hand.

Composite Raised Bed Gardening 

The composite raised bed for gardening is made up of wooden fiber, and plastic materials. It offers the best features of both materials. As compared to the wood material, the composite garden beds cannot quickly rot, fade, splinter, or wrap. By using this material, the life of the gardening bed is prolonged.

This type of garden bed is exceptionally beneficial for garden designers. Molds of different shapes are used to make concrete blocks. Even the complex shapes of concrete can be created for elaborating on a specific design. These concrete blocks are available in pieces, and there is no involvement of any measurement or screw. According to the size of garden beds, one can get the required design and number of blocks. To ensure extra stability, steel bars can also be used for fixing blocks in the ground. 

Vinyl Based Raised Beds for Gardening 

For making vinyl raised beds, recycled plastic is used. These boards are shallow that needs minimum maintenance and will not fade, splinter, warp, or rot. Its customized design allows an easy installment without any manual cutting or fiddling. The cutting of the board can be done according to the tight requirements of space. As compared to the other garden beds, vinyl raised bed is cheap, durable, and lightweight. 

Plastic Based Raised Bed for Gardening 

The functionality of this bed is somewhat like that of vinyl-based raised beds. Still, here the significant difference is the type of material. Polyvinyl chloride resin is used to make vinyl, but the plastic is made by using polyethylene of higher density. The polyethylene is chemically inactive and is phthalate and BPA free. It is an ideal bed for growing food crops.

Additionally, in the plastic bed, the chemical additives are UV inert, and there is no degradation or fading caused due to direct sunlight.

Most garden beds will follow the same rules regardless of what type of raised garden bed you choose.

Decide Where You Want a Raised Garden Bed

The selection of the site is the most significant factor when preparing the layout for a raised bed garden bed. The site should have direct access to sunlight along with appropriate drainage for water. The gardening area should be flat and should be at least 6-12 inches deep. Rocks, plant roots, weeds, and wooden chips should be removed from the ground. You can make the garden bed as wide as you want if you have the space. Just remember, you need to be able to reach the middle of your garden bed from either side. You don’t want to build something too high or too wide, which makes it difficult for you to maintain your plants.

Assembling and Filling of Gardening Beds 

The raised bed should be assembled on the site, or where this assembly can be easily moved. A large construction can be heavy, and its movement is somewhat problematic. If u decide to make a high raised garden bed, you will need to fill it with more soil. This will add pressure to the walls, so ensure your walls are thick. If you fear any burrowing animals around your neighborhood, then add a metal mesh to the bottom of the frame to stop the entrance of any animals. Before moving, the assembly frame, the site should be genuinely leveled. 

Filling your raised garden bed with soil and compost

The addition of gravel or wood mulches in between the beds provides dry, clean, working, and walking places. Don’t do this if your bed is raised too high. The soil used for filling the raised bed should be 50% soil of good quality and 50% compost. In some conditions, there may need to add soil amendment such as vermiculite to ensure proper drainage in rainy conditions. In hot and dry climates, soil that has excellent water holding capacity should be used.

Tips for Raised Bed Gardening 

 Alternatives for Wood 

You should be careful to avoid the chemical contaminated materials as it may cause the soil pH to change, thus affecting the soil biota in negative ways. Any significant change in pH level will negatively affect the growth and yield of plants. 

Use of Cedar Woods 

The wood of cedar has natural oils which stops quick rotting and increases the life span of the raised garden bed. However, before using this wood, make sure that the wood is not treated. 

Use of Thicker Planks and Railroad Ties 

To ensure the long-term use of a raised garden bed, choose a thick board of wood. A thicker and stronger wood can easily handle the weight of soil and plants. However, avoid the use of railroad ties as they are treated with the toxic material, creosote

Avoid Toxic Materials 

Raised garden beds are used for growing food crops, so wood or any other material should be free from chemicals. Otherwise, these chemicals can spread to your plants and produce.
