How to Prune your Hardy Geraniums

Hardy geraniums are known as the true perennial geranium, adored by gardeners everywhere because of how much they give compared to how much care they require. Hardy geraniums, such as Rozanne®, grow in most climates, take shade and sun in stride and often produce beautiful blooms until the first frost.

Here’s How To Prune Your Hardy Geraniums:

Hardy Geraniums vs. Pelargoniums

hardy geranium rozanneHardy geraniums are not to be confused with pelargoniums. What is the difference between a geranium vs. pelargonium, you ask? They are both members of the same plant family, but just like some siblings, they couldn’t be more different.

Hardy geraniums can live through frost while pelargoniums cannot. True hardy geraniums are perennials that come back each year, while pelargoniums die in the winter and are frequently treated like annuals, re-planted each year.

Properly pruning your hardy geraniums will help keep them looking their best and encourage new growth. You can inspire repeat blooming in your hardy geraniums by properly pruning them as soon as the blossoming period is over. Most geraniums can be cut back twice in one season, allowing them to bloom at least three times in one season.


When to Prune

You’ll want to prune your hardy geraniums according to the season you are in. Spring, summer and autumn will require different trims for Rozanne. So, mark your calendar and follow our seasonal pruning guide to help keep your blooms lush and healthy.

How to prune

There’s no need to worry about hurting your flower as you prune her back. Most hardy geraniums need to be trimmed to keep them from overtaking other plants and to encourage new growth.

Once the plant has finished blooming or you notice old growth, trim it back to within a few inches of ground level, or about an inch above the main stem. Then, go in and remove any brown stems or yellow leaves.

Shortly after trimming, you will see new leaves emerge! Some hardy geraniums will even experience a second bloom. Keeping your plants properly pruned allows them to have new growth and prevents them from sprawling out across your garden.
