My hardy hibiscus is coming in this year all curled up. The leaves on the new stem are also curled up and small. In late May I was expecting my hibiscus to come in strong but instead the stems are coming in with curled up leaves. The leaves are very small and very curled in. Also, the stem has a grayish film in it. What is wrong with the plant and how can I cut it?
Your plant is likely infested with Aphids or another sucking insect.
Treat the plant with Neem Oil.
Here are some links with more information.

My hibiscus is getting leaves that yellow and fall off. It gets plenty of water and Miracle Grow. Help. What am I missing?
This is very common in Hibiscus and can easily be corrected.

As I was shopping for dried hibiscus flowers to use in cooking, I noticed that some websites also had 'Sumac' in parentheses next to the the word 'hibiscus.' Are they the same or not? I am confused. Thanks, Deb Donnison
No, they are not the same. It appears that both plants are used in some of the same cooking methods.
My blue bird hibiscus are purple. Is the pH in the soil off and, if so, how can I change this?
It is not uncommon for the flowers to change appearance, the plant can age and even the sun can fade the flowers.
There are some varieties of blue Rose Of Sharon that are more true to the blue color.
Good care and growing conditions will optimize flowering but the Rose of Sharon flowers are not changed by ph.

I received a blooming hibiscus plant for Mother's day. I have fed it a couple of times with 15-30-15 and it is budded and ready to bloom again. However, almost every day, it has at least a dozen yellow leaves that I pick off. Any ideas?
Yellowing leaves are quite common on Hibiscus and can be due to a few different reasons.

I have a couple of hibiscus plants that the leaves have been eaten (they look like lace now) to where there is really no leaf left. Should I trim off leaves before I spray the plants?
Yes, you can remove the leaves.
Neem Oil is a good treatment.
Here are a couple of links with more information.

Should I trim it back to make it fuller and less leggy?
