Greenhouse

These categories are specific for flats or container plant(s) sampling, such as those used in a Greenhouse setting.

Always use these general guidelines for submitting a greenhouse sample.

  • Samples should be fresh.
  • Samples should represent the early to middle stages of the problem.  A completely dead and decaying sample cannot be reliably diagnosed.
  • Samples should be carefully packaged and shipped early in the week to avoid weekend layovers during which the sample will deteriorate.
  • Be sure to include sample documentation and background information.  The specimen form can be downloaded from:  General Form
  • Pictures of the problem in the field are always helpful.  The environmental conditions of the plant can play an important role in the diagnosis.
