Question

How do I pinch back perennial hibiscus?

Kristin Sharp

Community Answer

Cut them back close to the ground, leaving about an inch above ground. Once the last freeze goes and it starts to warm up, you will see your hibiscus start to get taller, and then beautiful blooms again.

When would I prune down a hardy hibiscus - fall or spring?

In early fall, but continue to pull dead blooms off all spring and summer to promote healthy blooms.

Question

My blooms tend to only last a day. Is there something I can do to help them last longer?

Community Answer

They are naturally 1-2 day blooms. Fertilizing with a high potassium fertilizer weekly during spring and summer will provide new blooms every day to replace spent blooms.

Question

Can I keep it in a dark room?

Kristin Sharp

Community Answer

Not if you want it to thrive. They need at least four to five hours of sunlight, and moist roots, to get the prettiest blooms.
