The Ontario Ministry of Agriculture Food and Rural Affairs has published its new Guide to Vegetable Production in Ontario – Publication 839.
A replacement for Publication 363, the new guide includes updated crop production and fertility guidelines, pest activity calendars, crop development stages, and images and information of pests, diseases, and disorders.
Publication 363 also includes expanded crop options, including herbs, specialty brassicas and vegetables, and sweet potatoes.
