steeplebush

The general rule for watering steeplebush (Spiraea tomentosa) is to keep the soil moist but not soggy. During the growing season, water thoroughly once or twice a week. Lift the plant’s foliage to check for moisture and, if the soil feels dry, water until the soil is damp but not soaking wet. During the winter months, water steeplebushes less frequently, usually about once a month or as needed. Keep in mind that, depending on the temperatures and other environmental factors, the watering schedule might need to be adjusted.

Steeplebush plants prefer full sun exposure, meaning 6 to 8 hours of sunlight per day when grown outdoors. They can also tolerate light shade, but full sun is ideal for optimal growth. Steeplebush plants are very adaptable and will not die if they get a few hours less than the ideal amount of sunlight. If they are grown indoors or in shady locations, it is important to supplement the natural light with artificial lights designed for plant growth. During the summer months, Steeplebush plants should be given plenty of light because they require up to 8 hours of sunlight a day for fruit production. In the winter the amount of sunlight needed per day can be reduced to 4-6 hours.

Pruning Steeplebush should take place in late winter or early spring when the plant is still dormant. Begin by removing dead, broken, or diseased wood, and any growth that does not fit in with the desired shape. After removing the dead, broken, and diseased wood, prune the remaining growth to increase air circulation, light penetration, and to promote a strong and full shrub. When pruning, remove up to 1-third of the branches each year, but be careful not to prune more than 1-third as pruning too much can damage the plant. After pruning, be sure to mulch around the plant to help keep the root system healthy.
