Horticulture

Illinois Extension has a vast collection of resources addressing horticultural interests across Illinois. We recognize that home and commercial horticulturalists each have unique needs, so we've cultivated a set of resources designed to address their top concerns. These collections represent the topic areas where we usually get the most questions, but our expertise covers everything from trees to tomatoes to tulips. Contact one of our educators with your questions!
