Q. I
have some of these roses that are the kind that they said are ground cover type
but they did very poorly in the Summer, when it was hot. Now I have planted
them in the shade and they leaves are turning white then falling off. Could it be that these expensive roses from the Cal coast will not do well
here? My other roses are looking great now and getting higher and higher.
These ground cover roses have never looked or done well.

Actually this is a very good climate for roses. The very
worst time of the year for them is Midsummer. When planting roses they need
full sun and lots of soil amendment at the time of planting. They benefit from
2 to 3 inches of wood chip mulch on the surface of the soil surrounding the
plants.

They don’t have a lot of pest problems like they would in wetter parts
of the country but in the shade you might expect powdery mildew. Powdery mildew
will cause the upper surface of the leaves to turn white and fall from the
plant. Powdery mildew seldom occurs if roses are growing in full sun and if
they are irrigated through drip irrigation, not overhead irrigation. Overhead
irrigation encourages the development of powdery mildew on rose leaves and
flowers.

I have many beautiful roses, but I have not had good luck with the (expensive) ground cover roses either.
