My D. adelae looks really bad. The leaves are dry with no dew. It keeps growing new leaves but they look shrivelled. It was fine all year until August or so. It was very hot this year. Above 95 F (many close to 100 F) for over 2 months straight. Almost everything in my small collection was stressed a little but most everything else has recovered. But not the D. adelae. They look pitiful and they are supposed to one of the easiest to grow. What can I do?
