Florist Testing During the Holidays

Since the University will be closed on November 23rd and 24th, we will move our Florist Testing schedule up to Tuesday (11-21) and Wednesday (11-22) that week.  Please make arrangements to have your samples to us by noon on Tuesday, the 21st if you'll need results that week.  Any samples that arrive after the deadline will be placed in cold storage and tested the following week.

We do not anticipate any other disruptions to our normal Wednesday-Thursday Florist schedule in the near future (including the Christmas and New Year Holidays).  As always, if you have any questions, or if we can be of additional service, please visit our website or contact us at your convenience.


The University of Minnesota Soil Testing Laboratory is part of the Department of Soil, Water, and Climate. We provide high quality testing services to the public, Universities, private companies, as well as State and Federal Agencies.
