===Irrigation===

Plants need water to grow. Water needs will vary depending on plant species, weather, and soil. An example is in Ontario, irrigation water is used most in late spring and in summer, when plants need water most, and based on climate patterns in Ontario, this time is also when there is the least amount of rainfall.<ref>OMAF Publication 841, Guide to Nursery and Landscape Plant Production and IPM↵↵<nowiki>https://files.ontario.ca/omafra-guide-to-nursery-and-landscape-plant-production-pub-841-en-2022-11-22.pdf</nowiki></ref> Some nurseries will create water sources by building a dam, or changing a watercourse.<ref>Ministry of Agriculture, Food and Rural Affairs.
