The harestailgrass genus, often referred to as 'bunny tails', prefer full to partial sun and moist, well-drained soil. They are not picky about pH level but do best in a cooler climate. Common issues include susceptibility to rust and leaf spots, and possible infestation by aphids or mealybugs. Seasonally, they require regular watering in warmer months, while in winter, they go dormant and need minimal care. In spring, they are typically sown as seeds and harvested in early summer when they display their charming, fluffy characteristics.
