Transplanting in summer adds heat stress to the already stressed plant. You need to keep it well watered (but not swampy) to help it recover. Hopefully you got most of the roots in the translocation. Mulch around it to conserve moisture and keep roots cool. If it is in a full sun site consider erecting a shade cloth for the hottest part of the day.
