Hi there
The flowers on our hibiscus open, then within a day close up tightly, and
sort of twist up.
Is this a type of disease or pest, and any ideas how to cure it.

Sounds normal to me. Quite a few hibiscus varieties have flowers that barely
last a day.

One pest that does affect them is hibiscus beetle. You would see the damage to
leaves and buds quite easily if you have them.
