Start the Pruning Process of your Spirea

First timers are usually nervous when it comes to pruning, and you shouldn’t be. The reason behind this is because spirea can cope with pruning even if you prune them brutally since they have the ability to grow back no matter how severe the pruning is.

If you have shrubs that are newly planted, then you don’t need to worry about pruning them that much. All you have to do is to give them a little trimming or reshaping during their first year.

#2. Keep a Few Buds per Stem

When cutting the stem of the spirea, it would be best to cut them back so that there will be a few buds left on it.

For you to successfully do this, make sure that your pruning shears or gardening shears are sharp. If you see any decaying or diseased growth, it would be best to remove them immediately. Weak looking stems and growth should also be removed.

#3. Start Thinning the Spirea Out

Now for you to ensure that the bush of the spirea will not become too dense, you need to ensure that the branches that are located in the middle would be thinned out.

This will help the congestion to be removed. To do this, cut some of the branches that are making your spirea bush thick.

#4. Removing the Suckers from Spirea

The next thing that you need to do is to ensure that any suckers that are undesired should be removed. The suckers are the shoots that are growing out of the rootstock of the plant.

You can do this by scraping some of the soil around your root and start tearing the sucker off. It would always be best to just scrape them instead of cutting them to prevent the suckers from growing.

Now, once you are done pruning your spirea, it would be best to give them some care. This is by providing them a fertilizer, water, and a new batch of mulch.

When choosing a fertilizer, it would be best to choose a slow release one, wherein a bone, fish, and blood are known as good options.

Start scattering the fertilizer under the spirea and gently rake them into your soil.

When it comes to watering, avoid overly doing this especially if your soil can’t be drained easily since it can ruin the leaves and turn them into a yellow color.

It is also ideal to add 2 inches of well-rotted, leaf mold, or compost around the spirea plant as these things can perfectly act as the mulch.

Another thing that you can do with your spirea besides pruning is dividing them. The reason behind this is because after growing your spirea they tend to become clustered and dividing them is the best option that you have.

To do this, you can divide the plant at their roots, which will not only help them be revived but will also help remove any growth that is old. You can do this during the late fall season since it is where they are dormant.

Everything that you need to know about the tips on how and when to prune spirea are discussed above.

Start caring for your spirea for you to ensure that they will stay healthy all year round.

Just don’t forget to water them and fertilize your spirea after the pruning process.
