Deutzia Plant: How to Grow, Plant and Prune this Flowering Shrub

Deutzia plants for your landscape.

If you want to attract pollinators to your garden consider this old time favourite. Many people love this spring bloomer for the dainty flowers it produces in the spring.

How to Grow in Containers

The smaller varieties can be grown in containers that will look great sitting on your deck or patio. 

If growing in containers the size will stay smaller than if growing in the ground and can also be used with spiller plants making a great focal point.

The Deutzia will need to be watered more frequently than if it was in the ground as the wind will dry the roots out faster.

How to Prune

Pruning your Deutzia should be done right after flowering. If you wait to prune them in July or later you will be cutting off the flowers for next year because they bloom on old wood.

Top prune the plant to remove any old flowers but don’t remove more than 1/3 of the plant.

Every year you should prune about 3 of the oldest canes to the ground. This will encourage new shoots for better flowering.

Pruning your plants will keep them looking fresh and happy.

Varieties of Deutzia

Pest and Diseases

There aren’t many pests and diseases that will affect Deutzias but here are a couple that might visit occasionally.  They are pretty much deer and rabbit resistant unless the animals are really hungry, then they might nibble on them.

Pests

Aphids – these little soft body pests will suck the sap out of your plants. They are usually in masses and can really do damage to plants, sometimes even killing it. They took over my butterfly weed and it didn’t come back the next year. Read more about Aphids here.

Leaf miners – You won’t see these tiny little common garden pests but you will see what they do to your plants. Brown squiggly lines through the leaves of your plant will indicate Leaf miners. Read more about them here.

Diseases

Leaf Spots – This disease is from fungus and bacteria spreading from one plant to another through spores. The leaves of the plant will develop small brownish coloured circles that will eventually grow bigger. To avoid Leaf spots try to water your plants in the morning or early afternoon

Propagation

Propagating the Deutzia is done in right after flowering. Cut a 4-5” stem and remove the old flower buds. Strip of the lower leaves, leaving 2-4 leaves on the stem.
