Japanese spirea

Spiraea japonica var. albiflora

Japanese Spirea is a deciduous shrub that’s relatively hardy and grows to around 3- feet tall. It features attractive clusters of white or pink flowers in the spring that are showy on rounded to arching branches. Its dark green leaves turn attractive shades of yellow, orange, and red in the fall. The Japanese Spirea prefers full sun and is tolerant of many soil types. It can also be pruned back during the summer months to add definition to its natural shape. With its beautiful blooms and vibrant foliage, the Japanese Spirea is a great addition to any garden.

watering

Japanese spirea should be watered deeply once per week, and require at least 1 inch of water each time. During periods of warm weather, an extra deep watering once every 2 weeks may be necessary to maintain the plant’s vitality. If the spirea is planted in an area that does not receive ample rainfall, watering will need to increase to twice a week. In addition, Japanese spirea benefits from having its soil mulched on a regular basis to help maintain soil moisture and also discourage weed growth.

sunlight

Japanese spirea thrives in full sun (at least 6 hours of direct sunlight per day). It prefers morning sun, but can usually tolerate some afternoon sun, particularly in climates with mild summers. It can also tolerate partial shade, though this may reduce blooming. For best flowering and form, provide full sun for at least 8 hours daily, but avoid afternoon sun if possible.

pruning

Japanese spirea should be pruned heavily once a year in the late winter or early spring, directly after the plant has finished blooming. This pruning should involve removing any dead, diseased, or damaged branches, and trimming back the healthy branches to frame the plant's shape while allowing for future growth. For older, established specimens, you can also cut back some of the oldest and thickest branches by 1-third to keep the shrub compact and promote new growth.
