Southern Indica Azaleas won't bloom - others are fine

Bumblebeez SC Zone 7April 24, 2009

I have a lot of azaleas and am always adding more.

Nothing unusual, however, but still attractive.

The kurumes, girards, glenn dales, robin hills and belguims all bloom beautifully provided we don't have a late freeze.

I have about an acre of yard landscaped with plenty of azaleas.

This is one gorgeous year too.

The Southern Indicas, zip. Maybe one of two flowers each year, if any, in 8 years. Most have no flowers.

Primarily I have G.G. Gerbing, Formosa, and George l. Taber.

They are intermingled with the others to give a long bloom time. Mostly they get bright shade.

All I can think of is to move them to full sun. None of them get full sun now.

This year I added 5 new formosas to full sun- so I'll see next year.

This is concerning me somewhat and I think I should move all the Indicas this fall.

Any thoughts?

I am posting this on the azalea forum also.

Thanks ggg! My gut has been saying to move them to full sun and I will- not a small task, which is why I asked.

They need some sun. Full shade or sun may be too much.

Also, do not prune them after August of the previous year or fertilize until after they bloom. They bloom on old wood and fertilizing too early can push the blooms right off. Late freezes can also zap the buds. Mine are just blooming now.

I don't fertilize them and I have never pruned them either. The other azaleas a feet away in the same amount of sun, water, soil...etc. bloom fine. The areas are bright shade though. I think it may be a sun issue becuase I can't figure out what else it is!

I have GG Gerbing, George Tabor, Pride of Mobile, and Formosa southern indicas. They are just 2 - 3 years old and planted in partial shade. Last year I was greatly disappointed in the lack of blooms. This year, all varieties put on a beautiful blooming show. I wonder if the amount of water they get makes a huge difference. We watered throughout the drought last summer and into the fall. Not sure why they decided bloom so heavily this year.
