Illinois Extension has a vast collection of resources addressing horticultural topics. We recognize that home and commercial horticulturalists each have unique needs, so we've cultivated a set of resources to cover everything from trees to tomatoes to tulips.
Call, email or visit any of our Extension Offices for answers to any and all gardening and lawn care questions including vegetable and fruit gardening, pest management, tree or shrub care and more. If possible, bring samples in a container or plastic bag, or take photos to help with identification and disease problems. You may also submit a question here.
