I have about 100 roses in the main gardens and have had
some nasty problems with an employee who sprayed most of the roses
with a roundup spray instead of a rose spray last summer (Yes, it was
on purpose). It broke my heart. I have started replacing them, but my
question is, is it enough to remove large areas of soil and replace
with new or do I need to take the entire soil from all the beds to
have healthy growth with new planting? I would appreciate any
experienced rose growers comments.

Thanks

Check out the David Austin roses web site. They have a new product - a
cocktail of friendly Bacteria/Fungi - that apparently inoculates the soil
against rose replant disease. I've used it for the first time in a
client's
garden (at his instigation) this year - I'm waiting with baited breath!

If you have a potential order for 100 roses to give them you can expect
personalised service!

The RHS garden at Rosemoor recently tried with some success planting the new
roses in the old rose beds by using strong cardboard boxes, dig a hole big
enough for the box (about 25lt size) then plant into it with imported
compost. apparently the box lasts long enough as a soil barrier that the
rose establishes before it is exposed to any infection from the old soil.
