Japanese Pieris

Looking for an easy-care spring-blooming shrub that supplies year-round beauty? Take a look at Japanese Pieris this season!

DESCRIPTION:

Pieris japonica is an upright evergreen shrub with spreading branches. It has the potential to grow 6-8 feet high and 4-6 feet wide. This is an easy to care for four season plant. Except when they emerge in early Spring with a bronzy hue, the leaves of the Pieris are lance-shaped and glossy deep-green throughout the year. The flowers appear in April and last well into May, a good six weeks! The urn-shaped blooms, like those of lily-of-the-valley, hang in heavy, drooping, pendulous clusters that are 3-6 inches long. The fruit is ornamental and will persist through the winter, but it is best to remove the fruit so that the plant will put its energy into developing next year’s flowers.

CULTURE:

Not as fussy as other ericaceous plants like heath and heather, Pieris prefer a moist, well-drained, acidic soil with a pH in the range of 5.0 to 6.0. When planting, amend soil with plenty of peat moss; this will aid in drainage and help make the soil more acidic. Organic matter like compost should be added to compacted soil to increase drainage and should also be added to sandy soil to enhance water retaining capability. Sulfur may be added to the soil to lower the pH if it is too high. Follow the instructions on the label. After planting, mulch the soil around the base of the plant with two inches of bark mulch, making sure to keep it from touching the trunk of the shrub. Pine bark mulch is a good choice when mulching Pieris because it will acidify the soil as it decomposes.

Pieris like a semi-shady location and will flower best in areas where they receive some sun during the day. Protect all broadleaf evergreens from the prevailing winter winds. If this is not possible, spray them in the winter with Wilt-Pruf, an anti-desiccant, to prevent winter burn. Pieris must be watered frequently during the first year after planting to encourage root growth. The addition of a root stimulator, such as Root Master B-1 with Hormones, at planting time will encourage the plant to quickly create deep strong roots. After becoming established, Pieris are relatively drought tolerant but they do, of course, grow best with consistent adequate moisture. Fertilize Pieris with Holly-tone, full strength in the Spring and half strength in the Fall.

Pruning of Pieris is usually not required. When purchasing, know the ultimate size of the cultivar you desire so that you may choose a suitable location in your landscape where the plant may grow to its full potential. If pruning is necessary, prune immediately after flowering so as not to interfere with the formation of next season’s buds.

DESIGN:

Pieris mix well with shade loving plants that require acidic soils such as azaleas and rhododendrons. Highly diversified in its design use, Pieris works well in a Japanese garden, woodland setting, shrub border, foundation and mass planting. The smaller varieties look great in containers and in rock gardens. Pieris are deer resistant shrubs.
