Thank you for your question. I'm not certain that the soil you are referring to is 'potting soil' or the soil that indicates it is specifically for raised gardens. You probably don't want to use the potting soil, which has vermiculite or perlite. The raised garden soil has lots of organic material in it, which keeps the soil from becoming too compacted. Here is an OSU Extension article about growing garlic: https://extension.oregonstate.edu/node/80811 With the exception of liming the soil, which you do not need to do with packaged soil, the directions are the same whether it is planted in native soil, raised beds or containers. Hope his is helpful.
