Spirea is a popular flowering shrub hardy in USDA zones 3 through 9. Whether you have one in a container that you want to move to the garden, or you have an established plant that needs to move to a new spot, sometimes spirea bush transplanting is necessary.

Spirea Bush Transplanting
Spirea bush transplanting from a container is easy. Pick a sunny, well-drained spot in your garden. Dig a hole that’s a couple of inches (5 cm.) deeper than your container and twice as wide. It helps to set the container in the hole as you dig to get a feel for the size.
Fill the bottom of the hole with a couple of inches (5 cm.) of compost. Slide the root ball out of its container and set it in the hole. Don’t shake out the excess dirt. Fill in the hole with a mix of soil and good compost.
Water thoroughly and keep the plant well watered for the next year. It may take as long as a year for your spirea to get completely established.
Moving a Spirea Shrub in the Garden
Moving a spirea shrub that’s established isn’t necessarily hard, but it can get unwieldy. Spirea shrubs can grow as tall as 10 feet (3 m.) and as wide as 20 feet (6 m.). If your shrub is especially big, you may have to prune back its branches just to get to the trunk. However, if you can reach the trunk, don’t prune it at all.
You want to dig up the root ball, which is probably as wide as the drip line, or the outermost edge of the plant’s branches. Start digging down and in at the drip line until you free the root ball. Moving a spirea shrub should be done as quickly as possible so the plant doesn’t dry out. It may help to wrap the root ball in burlap to keep it moist and to stop the soil from falling away.
Plant it in a hole prepared just like for container transplanting. If your foliage spread is wider than your root ball, prune it back a bit.
