The trouble with garden soil is that it may harbor pests or diseases. If you can bypass that and your soil drains well they should be ok. Only time will tell.

As dowlinggram said, only time will tell now. But personally, if they survive then as soon as they are big enough to be transplanted, I would remove them, replace the garden soil with a good potting mix, and replace them.

As you have discovered only soil-less potting mix should be used in containers - for many reasons. So to give them the best chance of survival consider transplanting them.

And let us know exactly what you planted? Some plants, namely herbs and some flowers will do ok in the dirt. Vegetables and most other flowering plants, not.
