Rock soapwort

Rock soapwort (Saponaria ocymoides) should be watered moderately throughout the growing season, usually 1-2 times per week. During the summer months, increase watering frequency if it is hot and dry. Allow the soil to dry out slightly between waterings, as this plant is prone to root rot if consistently overwatered. When watering, make sure to moisten the soil thoroughly and evenly. If grown in pots, water until water runs out of the holes at the base of the pot. In the wintertime, reduce watering and only water when the top 1 inch of soil is completely dry.

Rock Soapwort (Saponaria ocymoides) should receive at least 6 hours of direct sunlight a day. This species of plant grows best in full sun, but will also tolerate partial shade. It can tolerate hot summers and cold winters but when temperatures reach below 20°F, it is best to keep it covered. When started indoors, make sure the plant is receiving plenty of sunlight before transitioning it out to the garden.

Rock soapwort should be pruned in early spring, after the danger of frost has passed. Pruning should be done to remove any dead, damaged, or diseased foliage and to control the size of the plant. Light pruning can be done annually to maintain a desired size, as the plant grows quickly and can become overgrown in small spaces. About 1 third of the taller stem tips can be removed each year, which will promote bushy and healthy growth. If spring pruning is not done, the plant can be pruned in late summer to prevent undue damage due to wind and frost in the winter months.
