Hi, Littlegirl.
to ATP!
Is it just the top growth that's burning up, or are the roots dead, too? Is it planted with compost and/or protected with mulch?
One option that we use heavily here might be to grow it with mid-sized companion plants placed directly southwest and west of the troubled plant. Some plants that are otherwise burn-prone can be grown very successfully this way. Or, you might try growing it in a container. During the hottest part of the season, simply move it to an east-facing, protected location.
