What do I put on the bottom of a raised garden bed?

Introduction

Raised garden beds are a great way to grow your own food. But, what do you put on the bottom of a raised garden bed? Let’s find out!

Your raised garden bed needs to be well-supported.

You’ll want to be sure that your raised garden bed has a sturdy base. This is because the soil, and anything growing in it, will add weight to the structure of your raised garden bed.

You can use wood or metal for support. If you choose wood as your material for supporting beams or trellises, make sure that they are strong enough to hold up under repeated pressure from rainwater runoff during storms (and if possible avoid using pressure-treated timbers). Metal supports like these may also need additional bracing in order for them not collapse under their own weight over time as well as provide adequate stability while still remaining easy enough for anyone who wants access into their garden space without having any trouble getting around down there!

You can also try using netting along with bricks or concrete blocks as part of its foundation instead which should help keep pests away while still allowing air flow through so nothing gets too hot inside either way.”

A good bottom layer is the foundation of a quality raised garden bed.

The bottom layer of your raised bed is the foundation for the rest of your garden. It should be firm and solid, but not compacted. If you have soil that’s already loose and well-drained, this may be all you need to do to prepare it–just remove any large rocks or other debris from the area where you plan on building your raised garden bed.

If not (or if you’re just starting with bare ground), consider adding some materials that will improve drainage before adding the first layer of soil. You can use gravel or crushed stone; these materials will help move water away from roots so they don’t get too saturated with water over time. Another option is perlite: a lightweight volcanic rock that helps promote drainage while still providing good aeration for root systems as they grow downward into deeper layers below them!

Finally: think about how easy it will be for YOU personally when digging out old plants at harvest time!

A good layer of topsoil is important.

The next step is to add a good layer of topsoil. Topsoil contains organic matter and nutrients, which plants need to grow. It also acts as a reservoir for water, so you can water your garden less often. If you don’t have access to natural topsoil, look for one that has been amended with compost or other organic material.

A layer of mulch will help protect the soil and help it hold moisture.

Mulch is a layer of material that is put on top of the soil to keep it from drying out, such as grass clippings or leaves.

You can use manure or compost to enrich your soil.

Manure is a good source of organic matter, which will help your plants grow better. Compost also contains organic matter, but it’s already been broken down by bacteria and fungi (microorganisms). If you want to use compost instead of manure in your raised garden bed, make sure that the compost you buy hasn’t been treated with chemicals that may harm plants.

Some gardeners like to put down gravel to keep weeds out.

Gravel is a good choice for raised garden beds because it helps keep the soil from becoming compacted, which can make nutrients unavailable to plants. However, gravel isn’t suitable for vegetable gardens or flower beds because it doesn’t allow water and air to penetrate deeply enough into the soil.

Conclusion

In the end, your choice of a raised garden bed bottom will depend on what you’re looking for. If you just want something that works well and lasts, then maybe a simple layer of mulch will be enough. But if you want something more complex with different layers for different purposes (like topsoil enriched with compost or manure), then consider adding in some gravel as well!
