Description
Hostas are popular shade-loving perennials that can be used in nearly any setting, including borders, hedges, and even urban landscaping. Try pairing with coral bells, astilbe, or ferns to create a shady oasis along a border or mass plant under a large tree. The possibilities for use in the landscape are endless. The hostas in the Shadowland® collection from Proven Winners are vigorous growers and are more resistant to garden pests, like slugs. They're easy to grow, even in city environments, making them the perfect perennial for gardeners of any level.

How to Grow
Light: Part-shade to full shade.
Water: Average. Established plants have some tolerance for dry shade (particularly plants with thick leaves), but soils should never be allowed to dry out. Water is best applied directly to the soil beneath the leaves.
Spacing: 72" inches apart.
Fertilizing: In spring, a light fertilizer can be applied around the emerging plant, but not touching it.
Winterizing: Leave foliage standing in fall to help protect the crown. If desired, a layer of mulch can be applied in a 2" layer very near the base.
Maintenance & pruning: Groom plants by removing yellow or dead leaves and cut flower spikes back as they finish blooming in summer.
Plant spacing is based on the ultimate width of the plants. This figure is normally given as a range; for example, 3-5’. If you live in a cold climate and/or want plants to fill in more quickly, plan to space at the shorter end of the range. If you live in a warm climate, are on a limited budget, or are willing to wait longer for plants to touch, use the higher end of the range. Using the larger number is recommended when calculating distance from a building or structure. There’s really no such thing as "maximum spacing": if you don’t want your plants to touch, you can space them as far apart as you’d like. All plant spacing is calculated on center, or in other words, the centers of the plants are spaced one half of their eventual width apart:
Unless you are planting in a straight line, as you might for hedges or edging, space your plants in a staggered or zig-zag pattern for a more interesting and naturalistic look:
