Stephanotis blossoms fall off before opening all the way
I live in Houston, TX, and keep my Stephanotis plant outside to enjoy the humidity. My plant looks very healthy and puts on 20-24 blossoms at a time. However, they keep falling off before opening up completely. Help!

This plant is notorious for being very fussy about its environment. It will not usually fully flower, or fruit without the conditions being absolutely perfect. Although you may have some humidity, it is likely not near high enough to support flowering. This will be the primary cause of bloom drop.
These will also need fertilization very frequently. These can be a reason as well.
