Expert Response
Hi there,
Great question. Your perennial garden will benefit from watering 1-2 times per month during October through March. Ensure the air and soil temperatures are above 40F degrees with no snow cover. It is best to water midday before the temperature possibly drops. Below is a link with some more reading materials and perennials that are particularly susceptible to long dry spells.
