Do you deadhead rhododendrons or pune them back?

After flowering they should be dead-headed, snapping off the faded flower trusses just at the base, but mind the emerging new growth which is normally just below, and very close. Rhodos will set seed, often viable, but as it's not required, it's correct to remove the flower geads to ensure the plant directs its energies towards making growth and next year's flower. Phil J

Brill thanks, it's now on the to do list for Sunday :)

I got onto this yesterday morning and managed to clear all the dead flowers. It hadn't been done the year before either so there were 2 lots of trusses. The buds are well developed for the next bloom bso it wasn't too hard to avoid.

It looks a lot less shabby now, well except for all the holey leaves were something has had a great feed!
