Click here to subscribe online to be notified by mail about gardening classes or call 512-974-2550 and ask to be put on the emailing list for gardening classes. You will receive notification when a gardening class is scheduled. We usually offer classes a couple of times a year. Please also check the Grow Green home page occasionally. We post classes from multiple City departments and the Travis County Master Gardeners - but will not be sending out announcements for those classes individually.
