Sandoval County Master Gardeners

We are honored to have over 150 volunteer Master Gardeners in Sandoval County that have been trained and educated by NMSU to help serve the communities in sustainable high desert gardening. Visit the Sandoval County Master Gardeners for Questions on Gardening, Horticulture and More.

Plant and/or Insect Samples

Cooperative Extension provides plant diagnostic and agricultural insect identification services for the people of Sandoval County. Please contact SEMG or the Cooperative Extension Office at (505) 867-2582 to arrange drop-off, or contact the Master Gardener helpline to make arrangements at emailhelpline@sandovalmastergardeners.org. Please complete the Plant Specimen Submission Form (PDF) ahead of time. Please provide photos if possible, as many times identification can be made from photos.

Samples will be accumulated to be shipped weekly on Mondays. We request samples fit in no larger than a 9 x 12 USPS padded envelope. 

Soil Testing

NMSU no longer provides soil testing. Colorado State University has generously agreed to provide soil test analysis for New Mexico. For information, cost and instructions to mail your sample contact them here: Soil, Water and Plant Testing Lab.
