Boulder County Colorado flowers: annuals and herbaceous perennials
Paeonies need a balance of minerals including nitrogen, phosphorus and potassium, along with several trace elements. A general purpose mix (5-10-5) can be used annually in spring. Water it in well after application. Always follow manufacturer's recommendations when applying fertilizers. Colorado winters characteristically have dry air and low soil moisture. These conditions, along with little or no snow cover from October through February, can damage plants, especially new plantings. Watering during the winter is very important, depending on weather conditionsWater only when temperatures are above freezing, during the early part of the day. Some perennials prefer well drained dryer soil in winter to survive. See fact sheet 7.211, Fall and Winter Watering for more information.
