Answer: You can plant your strawberries in the garden and they should be fine this winter as long as you protect the crowns by piling about 6" of straw, pine needles, shredded leaves, etc. over the plants. I'd wait until late summer or early fall to plant them. If you must plant them now (in August), be sure to erect a temporary shelter so the plants don't burn up in the sunshine. The crispy brown leaf margins are probably a water issue - plants in pots can be over/under watered. Once the plants go into the ground they should be fine. This fall you can cut the oldest leaves off the plants. They will produce new leaves from the center or the crown of the plant. After frost has nipped the leaves you can cut them from the plant and then pile your protective material over the plants. Next spring brush the material away and stand back - your plants should produce lots of new leaves when the weather warms.
Best wishes with your strawberries!
