In keeping with its educational directive, Mercer Botanic Gardens and The Mercer Society (TMS) present a series of horticulture classes on successful gardening practices in Harris and surrounding counties. This program was developed for beginning gardeners, advanced gardeners, and individuals working in the horticulture field wishing to expand their plant and horticulture knowledge. Classes are taught by Mercer staff and horticultural experts.
