Risky, but if needs must, then what have you got to lose? It might be prudent to find out exactly what's wrong with your roses before using Jeyes, as it could be something that needs a particular chemical.

I fear you might lose your Philadelphus though - the rootball will be very large - possibly too large to fit in a container. Pruning it would help it survive if you could get the rootball out intact.

I thought Jeyes fluid was supposed to be used in solution as a disinfectant on greenhouses, tools and empty plant pots, not on compost itself - surely anything planted in "Jeyes Fluid Doused compost" will turn up it's toes and die. It will see not only the fungus off , but the roses themselves. I have seen this suggestion before for cleaning soil using it, but I think it MUST be a mistake:- it's a powerful phenol-based disinfectant and will kill plants as well as soil/compost flora and fauna.

Agree with Gattina you use Jayes fluid to disinfect the greenhouse not where you are going to plant. I do not understand where the idea has come from that you can use Jeyes fluid on the soil and then grow anything in the same soil... This is a disinfectant and kills just about everything - including all the good bugd etc you need in your soil!

I like the cryptic message above re armillotox. It tells you clearly on that website what can be done with this smelly product. Try reading it, and decide whether you want to use it. I am going to risk it on some of my Heuchera, it is said to kill vine weevil eggs. It does have a persistent pong. If one intends to throw summer parties, probably not a good idea. Excellent for warding kids off your front garden wall too.

love it Dorjac!

Since the EU stepped in, it's lost its distinctive smell. We used it successfully to keep badgers out, but the new stuff doesn't smell and doesn't work. :-((

Interesting, they claim the formula hasn't changed.
Luckily I still have the original from years ago :)

I wish I had some left!

The stuff I have, bought not long ago, has a pungent persistent smell of gas tar, brings back childhood memories of the 'tar and chipping men'. Mum had to use some of the butter ration to wipe the stuff off or margarine. We have poured Jeyes fluid down our fox holes, but this time I have used holly fronds stuffed in the entrance.( So far undisturbed) I don't suppose that would bother a badger much.

Thanks to all who replied - next stop garden centre (although I have had limited success with them in the past)

As to the Jeyes question, I was told by an old (91 yr) gardener when I lived in Plymouth where blackspot is rife that a weak solution of Jeyes on the top of the soil would sort the problem out for the next year. Mind, he DID say to do it in the winter when all the leaves were gone and after it had been pruned, and the plant was asleep (lol):)

But again thanks
