Frequently Asked Contact Questions
How fast are directory updates reflected on the website?
Once verified against land-grant university records, directory updates (such as updated office hours, phone numbers, or new soil testing laboratory fee schedules) are deployed live within 48 business hours.
Can I submit soil sample boxes directly to LocalSoilLab?
No. LocalSoilLab is an independent educational directory and research database. Soil samples must be submitted directly to your official state university soil testing laboratory or returned to your local county cooperative extension office. Refer to your specific county directory page for exact physical mailing addresses and laboratory submission forms.
How do I contact Master Gardener volunteers in my county?
Each county directory listing on LocalSoilLab provides direct phone numbers and plant clinic operational hours for local Master Gardener volunteer help desks. You can also reach out via our contact form above to request local hotline contact details.
