What Is a Raised Garden Bed?

A raised garden bed, commonly called a raised bed, is a container that is filled with plants and soil, and it is raised above the ground.

It consists of a box that has no top or bottom placed in a high-intensity sunny area with quality soil.

This makes it be the epicenter of the garden and offer pleasure and pride for the owner. In this area are various types of flowers that are well watered and focus on the sun for photosynthesis.

What To Put On The Bottom of Raised Garden Bed?

The aim of putting various substances on the bottom of a raised bed is to have a weed-free garden.

Now, the best way to go about it is by digging out the weeds in the particular area where you plan to place your raised garden.

However, if lots of grasses initially occupied the place, then you need to have a way of reducing it so that it will be easier to dig.

This is done by placing a hard substance like cardboard in the area for several weeks to kill the grasses.

Then the next thing is to get some thick substances like landscape fabric, cardboard, or some newspaper on the bottom of the raised bed.

This will prevent potential weed growth and provide the foundation with the necessary stability. Besides, it is recommended that these substances should be at least 1.2 to 1.5 cm in thickness.

However, some gardeners made it known that it is not necessary to put anything at the bottom of the bed.

To them, the mixture of existing soil and the one you will add to the raised bed is sufficient to improve the plant rooting that will be growing in the raised bed.

And that the need to place something in the bottom arises only when there are gopher problems, then you can place a hardware cloth to stop them from tunneling through into the bed.

However, it is generally recommended that raised garden beds should have some sturdy materials at their bottom.

This will reduce weed growth, solve the problems of gopher, and also provide stability to your garden bed.

Selecting the Appropriate Wood for Your Raised Beds

Are you one of the people that are worried about the safety of their frame of wood? If you are, then the solution is here.

Note that pressure-treated wood with CCA is not allowed since it leaks arsenic. But there are lots of options that will make your wood last.

Standard lumber that is pressure treated comes with chemical mixtures that can be applied to avoid the moist weather and soil from decomposing it.

Though the wood that is pressure treated is allowed, especially for organic growing, certain people still don’t accept it.

Woods, like cedar, have some natural oils that are capable of preventing rotten and enhance their durability; however, they are expensive.

If procured, they will last for a long time and offer outstanding service.

Also, another formula to have a longer duration from a block of wood is to choose the thicker ones.

Without treatment, a locally produced larch that is 2-inch in thickness can last not less than ten years.

Avoid the use of railroad ties because most of them have creosote, a dangerous chemical. Woods have substitutes such as bricks or concrete blocks.

But be assured that with concrete, the soil PH will be elevated with time, and you will need to be adjusting the soil to have the best garden.

Organizing the Site for Your Raised Bed

Establishing a raised garden has some prerequisites. First, make sure that the soils are loosed using the garden tools to break the underneath soils.

With this, they will not be compacted, and that is perfect for proper plant growth.

Then, for improved rooting, it is recommended to dig down the soil, a spades depth will be excellent. Mix the ground that is the top and the deeper layer together.

When grasses presently occupy the place you are planning to place your raised bed, then use substances like cardboard, landscaping fabric, or a tarp that will first kill the lawns.

Six weeks later or less, as it depends on the conditions of the weather, the grass will have been dead and become easier to cultivate your garden.

Soil for Raised Garden Beds

The most crucial component is the type of soil that you will put under your raised garden bed—the functions of almost all the other ingredients depending on how fertile the land is.

With poor soil, all other elements will fail.

Make sure that your garden is filled with mixtures like the topsoil and compost.

For a nutrient-rich environment, include some organic materials like manure to the soil mixture.

Take note that it is normal that soil in the garden bed usually dries fast, especially during the spring and fall time.

However, in the summer, a little straw, hay, mulch on the topmost part of the soil will make it retain more moisture.

Generally, raised beds do not need much maintenance, but constant watering will be necessary, especially when the plants are in their early stages.

This will ensure that the plants grow fast and appropriately.


Raised gardens are the nursery beds for the young plants. They can be made at home, in school, or in farming areas.

Making sure that the proper and fertilize soil is used for the bedding is the most critical step.

Some materials are recommended to be placed at the bottom of the beds primarily to decrease weed growth aside from many other functions.

Make a perfect raised bed and plant whatever you wish!
