My name is Osvaldo,
Would you please tell me what is the the best soil to use in box gardens to grow organic vegetables.
Thanks for contacting the Toronto Master Gardeners.
A simple mixture of triple mix plus compost – both readily available at garden centres – will work very well in your raised vegetable beds.
