Default red spots on JFK

Thanks Henry and Anne!

Henry, you were right. The roses in the picture look just like my roses.
Thanks for the identification and the advice!

Anne, thanks for the link to the local newsgroup, I've subscribed already.

Happy Gardening,
Heidi

Hi all,

I am new to this newsgroup...and to growing roses! My husband and I
recently adopted 2 JFK HT's from a quality local nursery. We planted
them, in a nice bed w/ hummus, good dirt, oscal, etc... After a week in
their new home our rose buds are opening with red spots on the petals.
Can anyone tell me what this is? Is this due to the record amount of
rain we have received in NC, or a lack/excess of nutrients? Is this
indicative of disease or pests?



It's been particularly bad this year for those of us on the east coast
and yes, the rain plays a big part. The spots are caused by a fungus
called botrytis cinerea. You should remove the infected portions of
the plant and destroy them. Application of fungicide will help
prevent further attacks but will do nothing for already-damaged tissue.

I take heart from the fact that these two pictures were taken at the
rose garden at the National Arboretum this spring. If they have
botrytis, I don't feel so bad that I do, too.
