Spirea Bush Varieties for Your Gardens
A low maintenance flowering shrub, the Spirea bush will add colour and texture to your garden. Caring for and pruning a Spirea is easy and I will show you how.
A Spirea bush (Spiraea) is low maintenance, fast growing, compact and an real eye catcher. Add one to your garden, as a container plant on your deck, or along your walkway.
I love the look of a Spirea. They are brightly coloured, very tightly compact and look great in any landscape.
They love full sun but will grow in part sun also. Once established they are drought tolerant and deer resistant. They are also great for attracting pollinators to your garden.
There are 2 different types of Spireas, Bridal Wreath variety and shrubby bloomers.
Bridal Wreath varieties bloom in mid-spring to early summer and have a cascading look to them with white clustered flowers along the stem.
Shrubby bloomers have a more upright look with different coloured flowers ranging from pink to red to white and bloom from summer until fall.
My Experience with the Spirea Bush
I have several varieties growing around my landscape. I haven’t had any problems with insects or diseases and they are said to be a hard to kill plant.
They are a versatile plant that can be used anywhere in the garden and can make nice low hedges along walkways and driveways.
I have seen a lot of pollinators around them, including bees and butterflies.
The 2 different varieties of Spireas get pruned at different times of the year.
For summer blooming plants, prune them in late winter or early spring, before they start to leaf out. You can prune them down to about 6 to 10 inches from the ground. This allows them to produce new shoots for better flowering and helps control the size.
For spring blooming plants, you will want to prune it right after it is done flowering as they bloom on old wood. Any pruning done later in the year will remove flowers for next year.

Meadowsweet (Spiraea alba)
An excellent native plant, Meadowsweet grows about 4' tall and wide with tall spikes of white flower clusters during the summer.
It grows best in full sun but can handle part shade and prefers to stay moist. It grows best along streams and ponds where there is enough water.

This plant will die back in the winter unlike other spirea bushes.

Pest and Diseases
Aphids – Small sap sucking insects that feed on the juices of plants. If you want to know more about Aphids click here.
Scale Insects – Covered in a protective cover these insects look like small bumps on the plant, usually on the leaves and stems.
Spider Mites – Microscopic spiders that also feed on the juices of plants. They attack both indoor and outdoor plants. Read more about Spider Mites here.
Fire Blight - Fire blight is a bacterial disease in the Rosaceae family. This includes apple, pear, hawthorn, crabapple and ornamentals members of the rose family. It affects the blossoms, leaves, twigs, and branches causing them to turn black and die.
Leaf spot Fungus – small brown spots appear on the leaves of both indoor and outdoor plants. They gradually grow bigger and join together and eventually kill the leaf.
To treat leaf spot disease, there are a couple different ways to stop it from spreading. A neem oil spray will work to prevent spreading or you can try a baking soda solution. Mix 1tsp with 1 gallon of water. Mix together and put it in a spray bottle and apply to your infected plant every 2 weeks.
Powdery mildew – This fungal disease affects many different plants including Spireas. It looks like white fuzz on the leaves that will turn a brownish colour with maturity.
To prevent it from occurring make sure there is plenty of air circulation around your plants and only water the soil, not the plant. A neem oil spray will help stop powdery mildew from spreading to other leaves. Only spray the leaves and not the flower buds or flowers.
