Diagnostic Services

Many diagnostic tests are available from the University of Florida:

The Hillsborough County office offers a soil pH testing service. This test provides the pH (acidity or alkalinity) and a recommendation for adjusting the pH if necessary. It does not provide any information about nutrients, diseases, insects or nematodes. pH tests are conducted every Friday morning, so samples should be submitted no later than Thursday. There is a $2.00 fee for each sample. Please make checks payable to "Master Gardener Program."
