Can 'David Austin Rootgrow' be used for perennials as well as roses?

United Kingdom Gb

I have used 'Rootgrow' mycorrhizal fungi for the planting of my roses as it is recommended for increasing the healthiness of them. But I am wondering whether there are other applications for it in the garden, particularly whether it can benefit perennials if sprinkled into the planting hole? Has anyone else used it this way? And would I be doing a good thing if I were to add it to John Innes compost when filling/planting up a pot, seeing as JI is pretty much sterile sort of stuff? (Moongrower are you there)?




I have a different brand of Rootgrow which says you can use it on anything other than acid loving plants.

Ah yes, I think I read somewhere once that it insn't suitable for heathers, so that would make sense.
