After they have blossomed, you can also prune early-flowering perennials like hardy geraniums, foxgloves, and primulas. Here are three justifications.
Promote more flowers
Early summer flowering herbaceous perennials like hardy geraniums (shown), alchemilla, and stachys can be pruned back to the ground as soon as the main flush of blooms begins to fade. It will be near the end of June in an early season. In the late summer or early fall, pruning promotes new growth and a second round of early blossoms.
Extend the life of plants
As soon as the blossoms on the lower half of the spike have faded, the flower stalks of short-lived perennials, such as lupins (seen in the picture) and many kinds of foxglove, should be trimmed back. This shifts energy from seed formation, which frequently causes the plant to die, to leafy development, encouraging healthy growth for an additional season.
Keep borders looking good
By June or July, perennials with spring or early summer blooms may appear disorganized as the foliage of some primulas and oriental poppies (shown) turns yellow or brown. Cutting it back can tidy up your borders and either cause the plants to go into dormancy for the summer or encourage them to grow new leaves.
As the summer progresses, many plants, including fruit trees and bushes with spring flowers, can be pruned. Learn what to prune in the summer.
Hardy Geraniums vs. Pelargoniums
Pelargoniums should not be confused with hardy geraniums. You might be wondering what makes a geranium different from a pelargonium. Similar to some siblings, they are both members of the same plant family, but they could not be more unlike.
Pelargoniums cannot withstand frost, while hardy geraniums can. Pelargoniums are usually treated as annuals and replanted each year, but true hardy geraniums are perennials that grow back every year. Pelargoniums die in the winter.
Prune your Hardy Geraniums
Your sturdy geraniums will look their best and promote new growth if you prune them properly. By correctly pruning your hardy geraniums after the blooming season, you can encourage repeat blooming. The majority of geraniums can be cut back twice in a single season, which allows them to bloom at least three times.
When to Prune
Your hardy geraniums should be pruned in accordance with the season you are in. Rozanne will require various cuts in the spring, summer, and fall. To maintain your blooms rich and healthy, mark your calendar and adhere to our seasonal trimming recommendations.
What tools you need
Your geraniums may be pruned fairly easily. All you’ll need is the ability to prune, a pair of sharp pruners, your favorite mulch, and your favorite gardening gloves. Watch this video to learn more about pruning strategies in detail.
How to prune
You shouldn’t be concerned that pruning your flower’s back will harm her. The majority of hardy geraniums require trimming to promote new growth and prevent them from encroaching upon other plants.
Trim the plant back to within a few inches of the ground or to about an inch above the main stem once the flowering is completed or you find old growth. Remove any brown stems or yellow leaves after that by going inside.
Soon after trimming, more leaves will start to appear. Some resilient geraniums even have the ability to blossom again. Maintaining correct pruning on your plants encourages new development and keeps them from spilling out throughout your landscape.

When should I prune my winter-hardy geraniums?
Geranium pruning can be done in three different ways. Depending on what you want to do, you can choose either one.
Pruning Geraniums After Winter Dormancy
The optimum time to prune geraniums is in the early spring if you put them into dormancy for the winter or if you live in a region where they lose some of their leaves over the winter.
Take off all of the geranium’s brown and dead leaves. After that, remove any diseased stems. Squeezing a healthy geranium stem will feel firm. Cut down the geranium plant by one-third, paying particular attention to stems that have begun to turn woody if you want a less woody and lanky plant.
Cutting Back Geraniums That are Wintered Alive
The best time to prune geraniums is in late fall or right before you bring them inside, if you intend to bring them indoors. If you do not put your geraniums into dormancy for the winter and they remain green in the ground or in containers year round.
Trim the geranium plant back by one-third to one-half, paying special attention to lanky or woody stems.
How to Pinch Geraniums
In order to make the plant grow more bushy and compact, geraniums are sometimes pruned. You can pinch either newly purchased bedding geranium plants or geraniums that have been overwintered. Pinching of geraniums begins in the spring.
When a stem on a geranium plant reaches a few inches (7.5–10 cm), cut off 1/4–1/2 inch (0.5–1.5 cm) of the stem with a sharp pair of scissors, or even with your fingers. Repeat over all stems. The geranium will be forced to produce two new stems off of the original stem as a result, which will result in a bushier, fuller plant. If you prefer, you can keep pinching geraniums all throughout spring.
Geranium pruning is simple and improves the appearance of your plant. You may enjoy your geraniums more now that you know how to prune geranium plants.
How should I re-prune my tough geraniums?
reducing after blossoming After flowering, early-flowering perennials like geraniums and delphiniums are pruned to almost ground level to promote new growth and late-summer blooming. Then, in the fall or spring, these are again pruned.
When and how should I prune geraniums?
Geraniums and pelargoniums are undoubtedly resilient and simple to grow, however they cannot be considered “no maintenance plants.” Giving them a hard prune at the end of the summer, when the flowering is winding down, is an excellent idea to prevent them from getting too leggy. In March or April, Jane advises cutting back geraniums and pelargoniums by a third to a half. The plants will grow quickly in the spring, bush out attractively, and produce a magnificent flush of blooms.
Don’t discard pruning cuttings; they make excellent propagation materials. Trim them to a length of 10 cm, remove all but a few of the lowest leaves, and set them aside so the ends can dry out. The cuttings may be potted up after a couple of days, and you’ll have some lovely new plants for your space come spring!
How are geraniums prepared for winter storage?
Your geraniums should be potted six to eight weeks before the final average frost date in your region. Clean up the plants by removing any extra-long roots and trimming the stems back to healthy green growth, as shown in the inset. Take the geraniums out of the bag or box they have been sitting in for the past several months. By the time it was cleaned up, this one was only a little over 4 inches long.
Then, put potting soil in a container that has already been wet, and tuck the stem down so that two leaf nodes are below the soil—this is where new roots will grow.
Is it okay to prune my geraniums in January?
First, decide if the type you have is a favorite and well of your time and effort. If it’s not, leave it to fend for itself in the garden and get a different type the following year!
Second, determine if you have adequate room for all of your delicate geranium plants. Few of us, especially if the plants have gotten extremely large, have enough frost-free space to keep every plant. You may either:
- Cut back the plants you have in containers so they can grow and bush out throughout the winter. If you have a lot of frost-free space, this works.
- Take pelargonium cuttings, and either discard the old plants or let them survive as long as they can. Cuttings utilize up much less storage space than full-sized plants because they are much smaller.
Do perennial geraniums require a fall pruning?
You should prune a perennial geranium after it has bloomed all season and starts to wither. This helps the plant store energy for the spring while simultaneously keeping it dormant for the winter. This could need to happen any time between August and late October, depending on your zone. Cut perennial geraniums down to 2 or 3 inches above the soil with a pair of trustworthy shears, ideally at nodes or new growth points. Take out any more flowers or foliage. You’ll have a collection of thick stems that is really ugly. But don’t panic, your blooms will return in full bloom the following spring.
Coral Bells (Heuchera)
Heuchera, often known as coral bells, has vibrant foliage from spring to fall and, in warmer climes, even into the winter. Coral bells shouldn’t be pruned in the late fall whether they are evergreen in your zone or not. Why? Through the winter, their foliage shields their crown. All you need to do is tidy up the plant in the spring to ensure another year of bright color!
Coneflowers (Echinacea)
Long-blooming perennial coneflowers (Echinacea) give bright color from summer till frost, but it doesn’t stop there. With noticeable seed heads, their flowers continue to be interesting long after they have faded. The seeds are adored by birds and other creatures, and they are frequently visited during the fall and winter by goldfinches, blue jays, and cardinals. You can always chop them if you’d prefer, but we advise leaving them standing in winter to bring texture and liveliness to the winter garden!
Black-Eyed Susan (Rudbeckia)
Black-eyed Susans, commonly known as Rudbeckia, share the prominent center cones of coneflowers and can be kept standing throughout winter. In the late fall and winter, you can see birds sitting on their wasted seed heads, which gives the winter garden a little bit of interest and excitement! It won’t harm the plant if you choose to cut them for a neater winter appearance.
*In the fall and winter, we adore how their black dry seed heads appear in dried flower arrangements!
Ornamental Grasses
Even though ornamental grass is merely a perennial, planting it is a proven way to give your garden four seasons of pleasure! The landscape is enhanced by the height, color, movement, and structure of ornamental grasses. The foliage takes on rich gold tones even when it is dormant in the winter and retains its structure until it is chopped down in the spring.
*Dried plumes can be brought indoors for decorating or used to hold snow and frost in the landscape.
Ferns
What makes ferns so great? observing the springtime emergence of their fresh fronds and their summertime unfolding. The fronds give the garden a fluffy texture and rich green, purple, or silver hues. Even though they may lose some of their color in the winter, they continue to offer texture and guard the crown until the spring when fresh fiddleheads sprout. Wait till you see new fronds sprouting in the spring before cutting back old ones!
Milkweed (Asclepias)
As a perennial native plant, milkweed (Asclepias) is essential for year-round pollinator support. Its leaf provides food for Monarch caterpillars in the spring. Clusters of nectar-rich blooms provide food for bees, butterflies, and birds in the summer and early fall. Keep your milkweed standing in the late fall and winter to give nesting pollinators a place to hide. They’ll be grateful to you come spring!
Red Hot Poker (Kniphofia)
Red hot poker, also known as Kniphofia, is a South African native that tolerates heat, humidity, and direct sunlight well. Temps throughout the winter? Despite the fact that some kinds are hardy down to zone 5, not really. To safeguard the crown, we advise leaving the foliage standing all winter. The flower stalks can be cut off, but save the rest of the cleanup for spring!
Cranesbill (Geranium)
Even in the winter, cranesbill (also known as geranium) is a hard-working perennial in the garden. They are semi-evergreen, which means that in moderate areas, they retain their green foliage throughout the winter. To enjoy some extra greenery during the winter, put off cutting the foliage back until April.
*You can always trim back cranesbill if you’d like if it isn’t an evergreen in your zone.
Stonecrop (Sedum)
Stonecrops (Sedum) may resemble indoor succulent plants in appearance, but they are surprisingly winter-hardy plants. Although their foliage and blossoms will wither away in the winter, we don’t advise cutting them. Why? On erect sedums, the dried flower stalks provide texture, color, and food for wildlife. They also have a lovely appearance while holding recently fallen snow!
False Indigo (Baptista)
Due to the sound-absorbing properties of snowfall, the garden is typically silent in the winter. Even though it’s inactive, false indigo (Baptisia) alters that by introducing texture, motion, and noise. Fall sees the replacement of spent blooms with seed-filled black pods that resemble tiny maracas. They make a little music when they rustle in the winter winds.
