Some Unusual Rose Conditions
This year the rose problems have been a bit different from other years. I thought it might be useful to list some of these to assist Master Gardeners when clients present problems with roses.
1. Symptoms of the first problem: In early June blossoms failed to open up normally This is referred to as “balling” of the blossoms. The edges of the petals were brown. The symptoms are more likely to occur on light colored roses. There are two possible causes listed in the textbooks. The first is botrytis, which occurs when we have periods of damp cool weather, so that’s hardly the cause this year. The second possible cause is an invasion of thrips. To check this, I opened the blossom and examined the petal base areas. There I found small, (1.0 nun) tan insects running around. Thrips do their damage by sucking juices from the petals. The trails for their successive penetrations shows a rasping pattern.
WHAT IS A LANDSCAPER?
A landscaper can be any individual or company offering services ranging from lawn care to maintenance, installation of plant materials, the contractor offering site construction services such as patios, desks, grading, or roadways, or the licensed landscape architect that offers design services. Generally, the businesses that offer landscape installation services beyond the services normally offered by lawn care businesses prefer to be called landscape contractors. Many nurseries and garden centers offer installation services and consider themselves landscape contractors, as well. Landscape contractors are not licensed, but are usually members of one or several organizations that set up standards for their industry. These associations include a Landscape Contractors Association, the American Association of Nurserymen, The Maryland Association of Nurserymen and the National Landscape Association (Division of the American Association of Nurserymen).
