Discoloured leaves on roses
 

My "city of London" roses are developing yellow leaves which are
dropping off. I have sprayed regularly with systhane and the leaves do
not have black spots.
Other varieties of roses in the same bed are unaffected.
I was wondering if it could be a iron or magnesium deficiency?
I have posted a pic if anyone can help
Thanks, Lisa=20

That sounds like my Blue Girl then Memorial Day. I sprayed as if they
had black spot. Finally I took some leaves to a reputable nursery for
inspection. Several attendants there looked at the leaves and said
there was no sign of disease on them, it looked like an iron
deficiency. (The leaves were turning bright yellow with spotting.)

They pointed me to a product called Rose-Tone, then to a mulch called
Hu-More. Both were pricey, but they have brought both my rose bushes
back around to a healthy state. I've also spread the Hu-More around my
other plants and they /love/ it. Both products contain alfalfa and
other meals for the plants.

Info on rose-tone can be found he

Hope this link works - it wasn't all highlighted in the other post LOL.
i'm in the UK so I'm not sure those products are available here but I
have given the bushes an iron and magnesium supplement so I am going to
see if that helps

thanks Elphaba - I am in the UK so I'm not sure those products are
available here but I have given them an iron and magnesium supplement
just in case and will see if that helps.

You may want to check this out about plant deficiencies:

Could be lack of nitrogen or magnesium (use epsom salts).

Good luck with the supplements! That's probably all it needs, but you
can always take some leaves to a nursery for advice too!
