The Texas AgriLife Extension Service and the Harris County Master Gardeners are pleased to offer the FREE Green Thumb Gardening Lecture Series. We have collaborated with the Harris County Public Library and Houston Community College to offer this program twice each month. Join us for one or both!
Every month, there is a new topic presented by experienced Harris County Master Gardeners. We share in-depth information for beginners to experienced gardeners. To access a printable version of the schedule, click Green Thumb 2025 here.
