Soil ph for planting bare root roses

I haven't planted the roses yet Neptune , have put them all in pots ....

Another factor that comes into the equation is the type of rootstock being used. Roses on Dr Huey prefer slightly alkaline soil i.e.just above 7 where as rose on multiflora rootstock prefer slightly acid soil i.e. in the vicinity of 6.5.    

The soil on the east coast of Australia in general terms tends to be acidic while areas such as SA, WA and inland Australia tends to be alkaline.

There is an article in the June edition of NSW Rose on pH based on a talk given by retired nursery man Laurie Stewart. Those who would like it a copy of the article email me a request for the same on [You must be registered and logged in to see this link.] and an electronic copy of the magazine containing the article will be sent.
