What To Put On The Bottom Of A Raised Garden Bed? – Guide

Raised garden beds have been growing in popularity over the recent years.

One of the most crucial things to know is what to place at the bottom of the bed.

What Is a Raised Garden Bed?

A raised garden bed, commonly called a raised bed, is a container filled with plants and soil raised above the ground. It consists of a box with no top or bottom placed in a high-intensity sunny area with quality soil.

Observing pest issues from a raised bed is easier since plants are at eye level. Structures allow you to work your bed without impacting the overall shape when the bed is contained in a structure.

This makes it the garden’s epicenter and offers 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 filling the bottom of a raised bed is to have a weed-free garden.

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 grass has initially occupied the place, you need to remove it for easier digging.

This is done by placing a hard substance like cardboard in the area for several weeks to kill the grass. The next step is to get a thick substance 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 materials are at least 1.2 to 1.5 cm thick.

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

The existing soil mixture and the one you will add to the raised bed are sufficient to improve the plant rooting in the raised bed.

The need to place something at the bottom arises only when gopher problems are there. You can then place a hardware cloth to stop them from tuneling into the bed.

It is generally recommended that raised garden beds have sturdy material at their bottom. This will reduce weed growth, solve gopher’s problems, and provide stability to your garden bed.

Selecting the Appropriate Wood for Your Raised Beds

Are you worried about the safety of frame wood?

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 prevent moist weather and soil from decomposing.

Though the pressure-treated wood 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 rot and enhancing their durability; however, they are expensive. If procured, they will last longer and offer outstanding service.

Also, another formula to have a longer durability from a block of wood is to choose the thicker ones. Without treatment, a locally produced larch that is 2-inch in thickness will not last less than ten years.

Avoid the use of railroad ties because most of them have creosote which a dangerous chemical. You can instead use woods that 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 adjust the soil for best outcome.

Organizing the Site for Your Raised Bed

You dont require a lot of space to have your raised bed garden built. You just need to make sure whatever spot you choose for it has good access to sunlight at most times of the day. Edible plants require proper sun exposure to fully mature and ripen. So, choose the area that is the most sunny on your property.

When it comes to establishing a raised garden, this can come with some prerequisites.

Firstly, make sure that the soils are loosed using the garden tools to break apart the underneath soils. With this, the soil will not be compacted, which is ideal for proper plant growth.

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