Position them in an area with more morning sun and then filtered light in the hotter afternoons during summer. Depending if they have rains, then that will help cool down her plants.
On my side, we get too hot, too dry so I also have to step up watering, so it is imperative my Amaryllis are in a well draining media and containers with drain holes.
Personally I don't like those marketing gimmicks where the bulbs are waxed. I would rather avoid getting those if possible.
