PROGRAM REQUIREMENTS ![]()
After completing Botany 1, remaining core courses may be taken in any order. If Botany 1 is not listed as a prerequisite, the course may be taken at any time. For the certificate, a grade of at least 70 percent must be achieved for each core course. All requirements for the certificate must be completed within seven years of the start date of our first core course. |
You can prove proficiency for up to 20 percent of the coursework by passing proficiency exams for approved courses or providing transcripts indicating grades of at least 70 percent for similar courses. There is no separate enrollment for the program. Students pursuing the Garden Design Certificate are encouraged to complete their Ornamental Plant Materials Certificate as well. This only requires the addition of 24 hours of elective credit. |
