|Browning foliage is not a good sign! The problem might be winter kill or might be associated with water stress (too much or two little). If it's winter kill you may be able to lightly prune the plants to encourage healthy new growth. If it's water stress the plants may recover later this summer. Be sure to water thoroughly, then allow the top of the soil to dry out before watering again. Plants in containers can suffer during the winters because the roots are exposed to cold temperatures. I hope that's not what is causing the browning foliage! I'm afraid only time will tell. I hope your curly tops recover soon!
