When and How to Plant Daylilies in Colorado: A Comprehensive Guide

Are you considering planting daylilies in Colorado? Here's your guide to the best time and methods for successful growth in this unique region.

Understanding Colorado's Climate

Colorado, being in Region 9 of the American Daylily Society, presents a unique challenge for gardeners. Its climate is characterized by variable winters with periods of heavy snowfall and clear skies. Summers, on the other hand, are dry and sunny, making it a distinctive environment for daylilies and other perennials. This variability makes careful selection and preparation essential.

Choosing the Right Daylilies

When purchasing daylilies, consider the source of the plants. Daylilies from northern regions are more suited to Colorado's climate, as they tend to be dormant during winters. In contrast, southern or warmer region plants often try to grow prematurely, leading to frost damage and poor survival. Stick to reputable nurseries and online sellers from climates similar to Colorado, such as Michigan, Minnesota, and northern parts of Ontario and Quebec.

Planting Techniques

When planting daylilies:

Timing: Spring is the best time to plant as daylilies can establish roots before summer's dry conditions. Alternatively, fall planting allows the roots to develop over the cooler months, ensuring strong growth in the following spring. Location: Pick a spot with well-draining soil and at least six hours of sunlight per day. Daylilies thrive in full sun but can tolerate partial shade in hotter areas. Preparation: Prepare the soil by mixing in compost or well-rotted manure. Amend the soil with sand if it is heavy or clay-based to improve drainage. planting depth: Place the plant at the same depth it was in the nursery container, ensuring that the eyes (growth buds) are above the soil line. spacing: Space plants approximately 18-24 inches apart to give each plant enough room to grow and spread.

Watering and Maintenance

To ensure your daylilies thrive, especially during Colorado's dry seasons:

Watering: Water your daylilies regularly, especially during drought periods. Daylilies can tolerate drought but will produce better blooms with consistent moisture. Mulching: Apply a layer of mulch around the plants to help retain moisture and regulate soil temperature. Organic mulches like straw or wood chips are ideal. Feeding: Apply a balanced, slow-release fertilizer in early spring and again in midsummer to support healthy growth and blooming.

Nurturing Early, Midseason, and Late Bloom

To enjoy a longer blooming season, select daylilies that bloom early, midseason, and late. Early bloomers typically flower in May, midseason varieties in June-July, and late bloomers in August. This spread in blooming periods ensures that you have colorful, fragrant daylilies from the start of spring until early fall.
