Cavatine Japanese Andromeda
A Compact Evergreen for Pots, Planters, and Containers
This dwarf Pieris shrub shines in small spaces.
‘Cavatine’ is a cultivar of Japanese andromeda (Pieris japonica ‘Cavatine’), a slow-growing evergreen shrub native to Japan, Taiwan, and eastern China. It is a member of the heather (Ericaceae) family, which also includes rhododendrons and azaleas. Japanese andromeda, hardy in zones 5-8, is grown for its attractive foliage and pendulous clusters of bell-shaped, lightly scented spring flowers, which can last for up to three weeks. Cavatine Japanese andromeda is a dwarf cultivar, growing slowly into a compact, rounded shrub similar in appearance to a rhododendron. Delicate white flowers are a favorite source of early spring nectar for mason bees, and deep glossy green foliage remains on the plant year-round. Cavatine Japanese andromeda grows 2-3 feet tall and wide, making it a great choice for containers, small gardens, and the front of a mixed border or shrub border.
Cavatine Japanese andromeda has specific cultural requirements, which give it the reputation of being somewhat fussy to grow. It requires moist, well-draining, acidic soil that is rich in organic matter, and grows best in full sun to partial shade with protection from hot afternoon sun and drying winds. Cavatine Japanese andromeda is the perfect companion to plant along side other acid-loving, partial-shade seekers like Japanese camellias, hollies, rhododendrons and azaleas. As with any other shrub, water deeply on a regular basis until the plant becomes established (see “How to Water your Plants” for help determining a flexible watering schedule).
Cavatine Japanese andromeda is one of the most deer-resistant shrubs or bushes you can plant. Pieris japonica is given high marks by Rutgers University on their list of Landscape Plants Rated by Deer Resistance. Deer don’t like the taste, and tend to leave it alone. However, no plant is 100% deer resistant, and deer will eat anything when their favorite tasty plants are unavailable. It's worth noting that while Cavatine Japanese andromeda is a beautiful and popular ornamental plant, parts of it can be toxic if ingested, so it's important to be cautious, especially if you have pets or small children. Cavatine Japanese andromeda does not behave aggressively in the garden, and is not considered invasive in the United States.
How to Plant and Grow Cavatine Japanese Andromeda
Planting: The best time of year to plant Cavatine Japanese andromeda is in the spring or fall, giving the roots time to establish before the onset of extreme hot or cold weather. Cavatine is a popular, widely available cultivar of Japanese andromeda, but keep in mind that nurseries and garden centers typically have the best selection of plants in the springtime. If you wait until fall, the Cavatine cultivar may be sold out until next spring.
Location: Choose a site with well-drained, slightly acidic soil. While Cavatine Japanese andromeda can tolerate full sun, it prefers partial shade and protection from the intense afternoon sun.
Wind Protection: Plant Cavatine Japanese andromeda in an area where it receives shelter from strong, drying winds.
Soil: Amend the soil with organic matter, such as compost, shredded leaves, or Leaf-gro®, to improve drainage and soil fertility. Ensure that the soil pH is slightly acidic, in the 5.0 to 6.0 range. Consider getting a soil test.
Mulch: Apply a layer of organic mulch around the base of the plant to retain soil moisture, regulate temperature, and suppress weeds.
Watering: Keep the soil consistently moist but not waterlogged, especially during periods of drought. Deep watering is preferable to encourage the development of a strong root system (Are you in a drought? Check the U.S. Drought Monitor).
Fertilization: In spring, after flowering, feed Cavatine Japanese andromeda with a balanced, slow-release fertilizer formulated for acid-loving plants (like Holly-tone®).
Pruning: Prune Cavatine Japanese andromeda sparingly; this plant has an attractive shape and is best left alone. Remove dead or damaged branches and prune lightly to shape, as needed, after the plant has finished flowering.
Pest and Diseases: Cavatine Japanese andromeda is susceptible to lace bugs, mites, and root rot. Keep an eye out for these pests and diseases. Insecticidal soap or horticultural oil can be used for control. Ensure good air circulation to minimize the risk of diseases.
