I just put together a 10x4 raised bed garden using cedar boards stacked 2 high.
I am a little concerned that the small gap between the stacked boards will let water seep out.
Could you provide any recommendations for sealing this gap? It would have to be soil/food safe.
My initial thought was to use 100% silicone caulk along the inside of the gap. Do you think this is a good choice or are there better options?
