Every year, a total of 4 hours of education must be acquired to retain Tree Care Advisor active status. This is to affirm that volunteers are receiving the most up to date information on tree care. These 4 hours can be obtained by attending reputable education opportunities through universities, Master Gardener Updates, Master Naturalist classes, Minnesota Water Steward courses, and several other outside opportunities. Update training classes, better known as Tree Essentials classes, are offered on occasional Fridays in the summer and early fall on the St. Paul Campus UFOR Nursery. We also host an annual UFOR Field Day on the St. Paul Campus in August.
