So how long does a raised garden bed last? It really depends on the material of the raised bed; most gardeners choose cedar or redwood because of their natural resistance to rotting and infestations. In optimal conditions, they’ll last up to 10 to 20 years.
How do I keep my raised bed from rotting?
- Choose rot-resistant wood.
- Stain the wood.
- Install a liner.
- Use stone to build the bed.
- Use plastic to build the bed.
Do you have to replace raised bed soil every year?
The soil in your raised beds will break down over time; however, you don’t need to replace all of the soil in your raised bed garden to have beautiful, vibrant, or bountiful plants. Before planting the following growing season, add Miracle-Gro® Refresh™ Soil Revitalizer to your old soil, following package directions.
