Prevention

Preventing flower problems is often the best way to avoid having to use treatments that may be labor intensive, costly, or cause a threat to other nearby plants, people, or animals.

Review the following publications for flower problem prevention methods:

  • Disease Prevention (University of Minnesota Extension Master Gardener training slide series) discusses prevention strategies and provides examples of common flower problems.
  • Insect & Disease Management in Annuals (University of Georgia Extension) describes how to prevent, diagnose, and control insect and disease problems that affect annuals. Much of this advice can be applied toward perennials, too.

Detecting and Diagnosing Problems

When selecting flowering plants from a catalog, nursery, or garden center, one rarely visualizes a tattered, stunted, or disease-infested plant as the end goal. When disease, insects, environmental conditions, or animal damage interfere with plant health and beauty, it is natural for its caretaker to look for ways to prevent or remedy the problem.

Prevention and remedy begin with an investigation or gathering of information to accurately identify the cause of the problem.

See the following resources from University of Maryland's Plant Diagnostics Web site. The first one will walk you through the process of identifying plant problems, and the second, the flower photographic keys, provides pictures and examples of common flower problems.
