**At this time, we are only taking inquiries/requests for information via email**

If you have a sick plant, bring us a sample—a small branch with a number of leaves needing diagnosis.  It's helpful to also bring a sample of a healthy portion of the plant if available.  Be sure to seal all plant and insect specimen in a plastic bag to avoid spreading any pests or diseases.

If you email us with your question, please be sure to tell us the location/address where the plant is, what type of plant it is, how old it is, how much sun and water it gets, if the problem just started or has been going on for some time, whether you use any chemicals (including fertilizer) on the plant, and anything else that may help in diagnosing the problem.
