You can use pine to build raised beds but it is a soft wood and will deteriorate within a few years. To help it keep from rotting too quickly you can treat it with an organic compound such as linseed oil. It's natural and won't leach into the soil and cause problems with your veggies (if that's what you're planting). Or you can use a harder wood such as cypress or redwood for your raised beds. These are naturally more resistant to rot and you won't need to treat the wood to make it last longer. Best wishes with your raised beds. |
