scalloped spirea

Scalloped spirea should be watered moderately, about once a week during the growing season. During this time, provide sufficient moisture so that the soil is evenly moist but not soggy. During dry periods, the planting area should be watered more regularly. In the winter, it should be watered only occasionally, when the soil is dry to the touch. It is best to water in the morning rather than late in the day, as this allows excess moisture to evaporate throughout the day.

Scalloped spirea needs full sun for at least 6 hours per day in order to grow and flower properly. It also needs some protection from strong winds, so it is best planted in an area where it will get sun for most of the day but be sheltered from the wind. In the summer months, when the days are longer, the length of time in direct sunlight may be increased to 8 hours per day. In the winter months, the amount of sunlight can be reduced to 4 to 6 hours per day.

Scalloped spirea (Spiraea crenata) should be pruned in early spring, just before new growth begins. Pruning should be done moderately, removing only one-third of the stems each year to keep the shrub full and healthy. The goal is to prune the scalloped spirea lightly every year to encourage new growth and remove dead and undesirable foliage. Make sure to wear safety goggles or glasses, as well as gloves, when pruning.
