Timothy, commonly referred to as 'Timothy Grass', is a perennial grass genus that enjoys full sunlight and requires well-drained soil. It is fairly tolerant to a range of temperatures but performs best under cool conditions. Watering needs are moderate, and over-watering must be avoided. Common challenges include dealing with crown rust, leaf spots, and aphids. Seasonal care involves more frequent watering in summers due to increased evapotranspiration, while in winters, timothy enters dormancy requiring minimal care.
