The UC Master Gardeners of Humboldt and Del Norte Counties offer free classes, workshops, and events throughout the year. Our programs are designed for home gardeners of all experience levels. Whether you're just starting your first vegetable garden or you've been gardening in our communities for decades, there's something for you.
Our events include hands-on workshops on topics like pruning fruit trees, starting plants from seed, composting, and water-wise landscaping. Registration may be required for most events to ensure we have adequate space and supplies.
We add new workshops throughout the year, so check back often! You can also sign up for our monthly newsletter to receive event notifications and seasonal gardening tips directly to your inbox.
