Excerpted from OSU's Master Gardener Online course, the Master Gardener Short Course Series allows students to study specific fundamentals of gardening. The various subject areas of the OSU Master Gardener curriculum encourage participants to learn the art and science of growing and caring for their own plants.

Please note: Taking all self-paced courses will not allow you to receive a Certificate of Home Horticulture or become an OSU Master Gardener. These courses are entirely self-paced and are not taught by an instructor. Also note that you will have access to course materials for one year after your registration date.
