Can I split Japanese azalea?

If you can tease the roots apart without breaking them that's a good idea, if my memory serves me right I think they are acid loving plants and need an ericaceous compost when you transplant them.

Thanx Tussiemussie iv got the Ericaceous Compost 2 do the job ;)

Don't forget - if you have hard water, give them rain water, not from the tap

Thanx Andrewr id seen that somewhere & so i give it the water from my Water Butts in garden:)
