Soil for Large Planter Box
At my mom's nursing home, large elevated planter boxes probably 5 or 6 feet long, 1 foot wide, and 2 feet deep have been installed for the residents to plant veggies in. What soil would be best for this, a garden soil or potting soil? And is there a brand to look for that is better? I'm assuming with a box this large you wouldn't be changing the soil out every year. Any suggestions for this would be appreciated. Thanks.
