spirea

Spirea should be watered deeply and infrequently. Water Spirea once a week in the summer months and every other week during the colder months, making sure the soil is always moist but never soggy. If the topsoil is dry, water the plant until the water runs out the bottom of the pot. If the Spirea is planted outside, check the soil in the ground every few days to make sure it is moist. During the summer, Spirea may need more frequent watering during extremely hot and dry weather.

Spirea (Spiraea media) needs full sunlight to grow and flower at its best. Sunlight should be between 6-8 hours per day. Ideally, this species is best placed in a sunny spot that will give it direct sunlight all year round, as this will encourage good growth and an abundance of flowers. During periods when full sun is not available, plants should receive at least partial sun for several hours a day. This will help promote healthy foliage and flower growth.

Spirea (Spiraea media) should be pruned in late winter or early spring. Pruning should only be done when necessary, with the goal of maintaining the natural shape of the shrub. A light shaping prune can be done in late winter, as this will encourage early growth and blooming. Group 1 varieties should be cut back by 2 to 3-quarters, while Group 2 varieties should be cut back by about 1-third. A light tidy-up prune can be done in early spring, focusing on removing any dead or diseased growth. Additionally, any misshapen branches should be removed in order to maintain the shrub’s overall form.
