The hot summer has taken a toll on grass throughout Ontario but will recent rainfall help? It depends. Plant agriculture professor Katerina Serlemitsos Jordan, a researcher at the Guelph Turfgrass Institute, told the CBC that, although grass isn’t functioning at the moment and we’re unsure whether recent rain will help, a prolonged period of rain can help lawns bounce back. Jordan studies sustainable turfgrass management, and plant pathology and nematology of various horticultural crops.
