What’s your horticulture comfort level? Do you know what a tomatillo is? To know how to garden means you will never go hungry! The 4-H horticulture skill-a-thon is a contest that helps youth identify flowers, indoor plants, landscape ornamentals, fruits, nuts, berries, and vegetables. Be ready to expand your knowledge on greenhouses, turf, plant nutrition, landscaping, managing lawns and trees, and soil health. If this is something that interests you, contact your county 4-H youth program advisor.
Ages and Stages of Youth Development
Beginners
Youth prepare for the contest by studying the Beginner Plant Parts Study Guide and Your Vegetable Garden Study Guide for a written test. Learning the basic skill of gardening will be helpful for judging and vegetables and fruit ID.
Juniors
The Junior/Senior Plant Parts Study Guide and NJHA Study Guides will prepare youth for a written test as well as ID vegetables, fruits, nuts, berries, and landscape ornamentals and judge fruits, vegetables, and flowers/indoor plants.
Seniors
Youth will continue to build upon their previous horticulture identification and judging skills which will also include landscape ornamentals identification. Seniors will also take a written test.
