What types of wood are best for garden beds?
When selecting wood for garden beds, certain types are recommended for their durability and safety for plants. Cedar and redwood are often favored because they are naturally resistant to rot and pests. The oils in these woods can help prolong their lifespan in outdoor conditions, giving you a sturdy and sustainable option for your garden.
Other suitable options include treated pine, which is budget-friendly and commonly available. However, if using treated pine, it’s essential to ensure that the treatment is safe for growing edibles, as some chemicals can leach into the soil. Ultimately, your choice should consider both the type of wood and its intended use in relation to the plants you plan to grow.
How long will different types of wood last in a garden bed?
The longevity of wood in garden beds varies significantly by type. Cedar and redwood can last about 15 to 30 years, making them excellent long-term investments. Their natural resistance to decay means they do not require frequent replacement, saving both time and money in the long run.
