Hi Sue,

I live in Loveland CO, very similar to the eastern plains of our state.

The common problems with diseases are powdery mildew on new growth and black
spot on the mature leaves. Rust is not very common and downy mildew is also
uncommon. As to pests, thrip and aphids are the usual critters.

The Ortho book, 'All About Roses' is an excellent source of information.

The Devner Rose Society is holding our anual symposium tomorrow at the
Devner Botanical Garden Center, I believe you will find it worth your time
to attend. The
Denver RS also has a local publication "Growing Roses on the Front Range"
that is specific to our climate and conditions. It contains an extensive
list of varities that do well in this climate.

We also have a rose food, Mile-Hi Rose Food that is all organic that has
produced excellent results for me.

One of the common problems with the commercial plant foods is a lack of
micro-nutrients. When selecting a rose food read the label and be aware of
more than just the three primary nutrients. Miracle Grow 15-30-15 does
contain nice supplement of micros and can be used as a primary food or as a
supplement.

If you are interested in attending the symposium tomorrorw at 9am see the
