These flowering shrubs are landscape favorites because they don’t require much maintenance to look attractive.<\/p>

<\/div><\/div><\/figure>

This diverse group of flowering shrubs comes in many sizes, colors, and forms. Plus, they’re easy-to-grow plants that are hardy in most regions of the country, especially Zones 4-10. Spireas are very fast-growing. Some of the old-fashioned varieties of spirea have been landscape favorites for decades, but these older\u00a0varieties can take up a lot of space and look best when not pruned. Newer types work well in suburban yards where colors and size are important.<\/p>

\u00a0<\/div>

Spirea japonica<\/em>\u00a0is probably the most common member of this\u00a0group of shrubs. It has a much more manageable size of 2 to 10 feet wide at full growth and comes in an assortment of colored foliage, and even has a variety of bloom colors. The shape of this spirea is much more dense and short.<\/p>

Where to Plant Spirea<\/span><\/h2>

Plant spirea in well-drained soil in a location where it will get full sun most of the day. Spirea is a good plant to use for hedging, for privacy lines, as a background for showier flowers, or massed along a sloping part of your yard for erosion control.<\/p>

\u00a0<\/div><\/span>

How and When to Plant Spirea<\/span><\/h2>

Dig a hole where you want to plant a spirea shrub the same height as the root ball and two to three times wider than the roots. Remove the plant from its nursery pot and tease the soil from the roots. Place the plant in the hole and backfill with soil. Plant them\u00a02 to 15 feet from each other, depending on how wide you expect them to be at full growth. For a dense, full spirea hedge, it’s OK to plant them closer together but give them some room to breathe. Add mulch, but don’t let it touch the stems. As with most shrubs, it’s best to plant spirea in the fall.<\/p>

\u00a0<\/div>

Invasive Plant<\/h3>

Spirea is listed in the Invasive Plant Atlas for the United States, where it is described as being on the invasive species lists of several states in the Northeast and the South. Check with your state’s agricultural department before planting.<\/p><\/div><\/div><\/span>

Spirea Care Tips<\/span><\/h2>

All of the different spireas have fairly similar site requirements. They will ultimately be\u00a0happiest in full sun\u00a0with good drainage, but if pushed, they can manage in some shade. They don’t need much extra watering once they have become established in your yard (usually after the first year after planting).<\/p>

\u00a0<\/div>

Light<\/span><\/h3>

Spirea shrubs should be grown in a spot with full sun six hours a day for the best flowering. They can, however, tolerate partial shade.<\/p>

\u00a0<\/div>

Soil and Water<\/span><\/h3>

Grow spirea in soil that’s moist and well-drained. The soil can be sandy or clay-based, and spirea doesn’t need a particular pH type. When planting, water the plants thoroughly and spread two to three inches of mulch around them. Keep the soil moist but not soggy. It’s better to water deeply but less frequently.<\/p>

\u00a0<\/div>

Temperature and Humidity<\/span><\/h3>

Spirea will grow well in\u00a0most Zones, and they’re deciduous, so they lose their leaves during the cold winter months. They don’t require any special care for cold or hot weather, though their soil should be checked if it gets very hot to see if it’s dry and needs watering.<\/p>

\u00a0<\/div>

Fertilizer<\/span><\/h3>

When spring begins, apply a control-released fertilizer formulated for trees and shrubs. For the amount to use, follow product label directions. Reapply each spring.<\/p>

\u00a0<\/div>

Pruning<\/span><\/h3>

After it flowers, give spirea a good trim by cutting back the flowering tips to the top leaves. You may even be rewarded by a second flush of blooms.<\/p>

\u00a0<\/div>

Newer types of spirea form almost perfectly round mounds that can easily be pruned back to the ground each year to encourage a fresh new spurt of growth. This also helps to prevent them from getting a hollow center, where most of the old growth in the middle of the plant no longer puts out growth and just the tips leaf out.<\/p>

\u00a0<\/div>

Potting and Repotting Spirea<\/span><\/h3>

To pot spirea, use a resin container with good drainage and plenty of room for growth since spirea spreads out as it grows taller. A pot with 6 to 8 inches more width than the root ball is the right size. Choose a potting soil and add a product, like perlite, to help with drainage. Full sun is a must for potted spirea. Periodically, check to see if the soil is dry up to 2 inches on the top. If it is, the plant needs watering.<\/p>

\u00a0<\/div><\/span>

Pests and Problems<\/span><\/h2>

Leaf spot and\u00a0powdery mildew\u00a0can be problems for spirea. Treat aphids and other pests as soon as you see them on your shrubs with insecticidal soap, repeating as needed.<\/p>

\u00a0<\/div>

Because spirea is invasive in some areas of the U.S., gardeners should check with their state’s local agricultural department before planting the shrub.<\/p>

\u00a0<\/div><\/span>

How to Propagate Spirea<\/span><\/h2>

Propagate spirea in mid to late summer when it’s in the softwood stage. You’ll know it’s ready for propagating when a young stem bends easily and breaks with a snap.<\/p>

\u00a0<\/div>
  1. Cut a 6-inch stem, strip its bottom leaves, and dip it in rooting hormone.<\/li>
  2. Place the stem in a container with potting soil, then cover it with a plastic bag for a few weeks.<\/li>
  3. Site it in a shady outdoor spot. In about a month, you should see roots forming.<\/li>
  4. Plant the new rooted stems in containers. Transplant to your yard in spring.<\/li><\/ol>
