Japanese spirea

Japanese spirea (Spiraea japonica 'Anthony Waterer') grows best in moist, well-drained soil and should be watered weekly to ensure that the soil stays moist. However, be careful not to water too much as this can lead to root rot. Depending on the weather, you may need to water more often in hotter months. In general, Japanese spirea should be watered deeply at least once a week, to a depth of around 10-12 inches. Avoid regular light misting of water, as this can encourage fungal diseases. In particularly hot and dry conditions, it may be beneficial to give the plant an extra drink to make sure it stays sufficiently hydrated.

Japanese spirea (Spiraea japonica 'Anthony Waterer') thrives in full sun to partial shade, preferring at least 4 to 6 hours of direct sun per day. This plant prefers moist, well-draining soils and does not do well in soggy or overly wet conditions. It is not overly fussy about soil pH levels but does require adequate nutrients to grow and bloom well. Pruning should be done in late winter or early spring to shape and control size.

Japanese spirea (Spiraea japonica 'Anthony Waterer') is best pruned in early spring, before new growth begins. If left unpruned, it will often become spindly and overgrown. Pruning should be done by removing 1/3 of the oldest stems near the base of the plant each year. Pruning will encourage healthy new growth and flower production. Additionally, remove any dead, diseased or faded flower heads promptly after they finish blooming in order to encourage continuous new flower buds.
