What are the instructions for making a raised garden?
You can easily style your raised beds if you have wood, stones, bricks, or cement blocks. Stay away from painted or pressure-treated wood, as they can leach chemicals or lead into your soil.
If you have enough bricks, you can place them end to end around the edges or arrange them end to end to make higher sides. To prevent weeds from creeping under the bricks and between them, bury a bit of the bottom to stabilize them.
Pine may be the cheapest, but it rots after a few years, and many other untreated kinds of wood will. Hemlock is slightly more durable.
Woods resistant to rot, such as cedar, redwood, or locust, will last longer; however, they are more expensive.
The best wood for decks is cedar because it is rot-resistant and durable, lasting for 10 to 15 years.
Additionally, the oil content of the wood provides insect resistance. It is also quite pricey, but recycled wood made from plastic bottles will last for a lifetime. It is also possible to choose untreated wood boards that are much thicker. Larch wood, for example, should last a decade without treatment if it is 2-inches thick. The chemicals in modern treated wood help prevent rot.
