Geraniums are a diverse species of hardy perennials that provide abundantly blooming plants for a variety of settings. The blooms, which come in vivid as well as more muted tones of genuine blue, lavender, pinks, and white, can be just as intriguing as the lobed foliage. The delicate container plants known as Scented Geraniums, Zonal Geraniums, and Martha Washington Geraniums have little in common with these plants (these belong to the same family, but a different genus, Pelargonium).
Light/Watering: These plants will perform at their best in light shade to full sun in the North and part shade in the South. Most are able to adapt to brief dry spells well, and all benefit from routine watering. In milder areas, Geranium sanguineum and its variants can withstand drought.
Geraniums do best on average, well-drained soils that range from slightly acidic to neutral, and they will benefit from a little springtime application of balanced, granular fertilizer. Most people can handle brief, dry periods.
When should cranesbill geranium be pruned back?
Hardy geraniums, also known as cranesbill geraniums, received their name from the way their seed pods are shaped; they resemble a crane’s bill. Hardy spreading perennials called cranesbill geraniums are used as fillers between gardens and shrubs, as a low-growing border, and to conceal the barren “ankles” of taller plants. The care of cranesbills is not very demanding. Your cranesbill will thrive and spread cheerfully if you prune the clumps three times a year and fertilize once in the spring. Give cranesbills lots of space because they want to spread out and aren’t afraid to encroach on (smother) nearby plants.
In the early to midspring, just as growth starts to show, prune cranesbill geraniums.
Trim damaged and dead stems back to just above the crown. Cut back side branches to the crown or shorten them by several inches if your cranesbill is expanding beyond its original location.

Midsummer or after the flowers have started to fade is the best time to prune cranesbill geraniums back to 6 to 7 inches. They will remain more compact as a result, and late summer will see another blooming burst.
In the early to mid-fall, prune faded flowers by making cuts just above a sturdy branch or bud.
How is a cranesbill kept from blooming?
Among the most common garden perennials are hardy geraniums, sometimes known as cranesbills. And it’s clear why. They require little care and maintenance, are hardy, easy to grow, and tolerant of a variety of environmental factors.
The bloom color ranges from vibrant to subdued violet, blue, pink, magenta, and white hues, and many have appealing veining in a stronger, contrasting hue. Throughout the summer and well into autumn, several types flower nonstop for months at a time, and some even begin blooming as early as late April. When in bloom, the flowers, which are typically rather small, are produced in such great quantities that they almost completely cover the plants.
Numerous species’ hand-like foliage, which exhibits varied quilting, veining, and color blotching, is also very appealing in and of itself. Additionally, because many of the popularly cultivated kinds are low-growing, they make wonderful ground cover plants due to their dense, carpet-like leaf.
They should not be mistaken with the very similarly related pelargoniums, which aren’t and are primarily used as summer bedding plants, as they are cold- and frost-hardy.
Cultivation
There are kinds that can thrive in direct sunlight, light shade, and even pretty deep shadow. They generally thrive in early morning and late afternoon sun, while some, like Geranium sanguineum and Geranium pratense and their variants, grow well in full light as long as the soil has enough moisture.
Hardy geranium varieties
There is at least one hardy geranium for every garden, every gardener, and every circumstance as there are about 70 species and 700 types to choose from!
Here are the top 10 items that the Royal Horticultural Society suggests:

- Jolly Bee and Geranium Rozanne (Gerwat)
Planting hardy geraniums
Hardy geraniums can be planted at any time of year, but planting in the fall or winter will ensure that the plants take root effectively and provide an abundance of flowers in their first season. For planting from late autumn to late winter, mail-order vendors often offer bare-rooted plants.
Make a hole that is sufficiently large to readily fit the rootball. Fork in a layer of organic material, such as compost or planting compost, at the bottom of the hole.
Place the rootball in the planting hole, adjusting the planting depth until the rootball’s top is level with the soil and the rootball is planted at the same depth as it was growing initially.
Fill the planting hole with the excavated soil after adding more organic matter to it. To maintain soil moisture and aid in weed control, thoroughly water the area around the tree, then sprinkle a granular general feed over the surrounding soil. Finally, put a 5-7.5cm (2-3in) deep mulch of well-rotted garden compost or bark chips around the tree’s root area.
How to care for hardy geraniums
The majority of hardy geraniums are undemanding, low-maintenance plants.
When the weather is dry during the first year, water thoroughly. To maintain healthy plant growth in succeeding years, watering may be required during extended dry spells.
Late spring mulching around the plants will assist retain soil moisture and control weed growth.
Plants may start to seem messy with sloppy growth after the first early flush of blossoms has faded. After the initial flowering, the majority benefit from a trim to freshen the foliage and promote more blooms. To get rid of the outdated, messy growth, just cut the plants with a pair of shears or secateurs, or more forcefully if necessary, to a height of 5-7.5cm (2-3in) above the ground.
Then feed them with a liquid plant food to promote new growth and additional flowering flushes. After each flowering, pruning and fertilizing can be done again to extend the flowering season of many kinds well into the fall.
With the arrival of colder weather in late autumn, most geraniums’ foliage will start to fade. If you trim the plants’ leftover stems and leaves, they’ll grow new, fresh growth the following spring.
Over time, hardy geranium plants expand, spread, and form enormous clumps. These can be chopped into halves or quarters with a sharp spade. This can be done in the spring when they begin to grow or in the autumn. Every three to five years, divide them to maintain good growth and flowering.
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.
Is it necessary to deadhead cranesbill geranium?
When my cranesbill geranium has finished blooming, should I deadhead and prune it back? The leaves frequently have ugly spots on them.
Although deadheading won’t increase flowering, it will make the plant seem better. Many gardeners postpone the time-consuming task of deadheading in favor of pruning back the entire plant later. When the plant starts to look bad, remove the seedheads and the old leaves. To reveal the flush of new growth at the plant’s base, remove old leaves. For the winter, leave the leaves uncut. In the spring, either get rid of the old foliage or let the new growth come through and cover it.
How is cranesbill prepared for winter?
The ideal course of action would seem to be to prune all of your perennials in the fall. I see why you would want to trim down the perennials and get ready for the upcoming Christmas season—you have lovely fall weather, you’re already raking leaves, etc. Unfortunately, our desires and the needs of our plants are not always the same. Here are some common queries about perennial winterization answered.
Depending on what you have planted in your garden, the process of effectively winterizing your perennials can frequently take place from late October into the first few weeks of spring. The most important thing when cutting perennials for the fall is to take your time.
A plant’s leaves are what give it life, so they should never be entirely clipped until after several hard frosts. It is possible for the plant to absorb the additional energy it requires by letting it naturally wither away. The plant moves its energy from the dying foliage to the roots, where it will be stored for the winter and used to grow a new, attractive plant in the spring. By pruning a perennial too soon in the fall, you run the risk of weakening it and having it perform poorly the next year.
The perennial variety will determine when to prune, but there are primarily 3 categories to consider:
- After the deadly frost, thoroughly prune the tree.
- In the spring or fall, prune to the base of the leaves.
- Never prune in the fall (prune or clean up in spring)
1. After the fall killing frost, totally prune the tree. Although pretty self-explanatory, be aware that this process could happen at any time between mid-October and December.
- When the foliage turns black, cut the anemone (Anemone x hybrid) to the ground.
- When the beebalm (Monarda) dies back, cut it to the ground. Occasionally, if powdery mildew is a serious infestation, this may need to be reduced early.
- Nepeta catmint should be cut down when the foliage turns brown.
- Cut down Cranesbill (Geranium) when the foliage turns brown.
- Hemerocallis daylily, cut to the ground as the leaf turns brown.
- Cut Hosta (Hosta) to the ground once the leaf has withered.
- Cut the iris (Iris sibirica) to the ground when the leaf withers or leave it for winter interest and trim it back in the spring before the new growth appears.
- When the foliage dies down, cut the peony (Paeonia) to the ground.
- Cut to the ground Sedum (Sedum) as the foliage dies back, or leave for winter interest and trim in the middle of winter or in the first few weeks of spring before new growth starts.
- When the foliage on tall Phlox (Phlox paniculata) dies back, cut it back to the ground.
- When the foliage on Threadleaf Coreopsis (Coreopsis verticillata) dies back, cut it back to the ground.
2. Completely prune in the spring or fall to the base foliage. A structure’s base is referred to as its basal. In its simplest form, basal foliage is fresh foliage that emerges at a plant’s base.
- Susan the Black-Eyed (Rudbeckia) For the benefit of wildlife, leave the seed heads up in the winter. In the spring, just wipe off the remaining leaves and cut the stems back to the basal foliage.
- Campanula (Bellflower): In the fall, prune back to the basal foliage.
- Coneflower (Echinacea)
- For the benefit of wildlife, leave the seed heads up in the winter. In the spring, just wipe off the remaining leaves and cut the stems back to the basal foliage.
- Penstemon (Penstemon digitalis) should be pruned in the fall to the basal foliage.
- Trim the stems of the Shasta Daisy (Leucanthemum) to the basal foliage in the fall, and then in the spring, only remove any leftover foliage.
- In the fall, cut back yarrow (Achillea) to the basal foliage.
Avoid pruning in the fall (prune or clean up in spring). Some perennials simply benefit from having more leaf on top in the fall to protect the plant’s crown, but evergreen and woody perennials should never be cut back.
- Aster (Aster) In the spring, before the emergence of new leaf, totally prune.
- Before the new leaf emerges in the spring, fully prune the asters.
- Monarch Butterfly (Asclepias tuberosa)
- It’s not necessary to wait until spring to cut this back, but because it blooms later than most other perennials, it’s usually simpler to leave it alone so that it can freely reproduce. In order to avoid mistaking the new seedlings for weeds come spring, you’ll need to know where it was in your garden.
- Although it is not required to wait until spring, Cardinal Flower (Lobelia cardinalis) benefits from the additional leaves on top to help protect the plant’s crown.
- Camembert Pinks (Dianthus gratianopolitanus)
- Simply remove the dried flower stalks and any untidy foliage in the spring after they bloom because these have evergreen foliage.
- Coralbells (Heuchera) have evergreen foliage, so in the fall, cut the flower stems to the base foliage, and in the spring, tidy up the foliage as needed.
- Invading Phlox (Phlox stolonifera)
- Simply clean the foliage once the spring blooms have passed since these have evergreen foliage.
- False indigo (Baptisia australis): Either leave the foliage for the seed heads, or cut it back completely as new growth starts to emerge in the spring by cutting back by a third in the fall.
- Lavender (Lavandula)
- Since lavender is a woody perennial, they only need a small amount of shaping trimming in the late fall or early spring. Avoid forcing growth before a frost by not pruning back too early; you want the growth to be hardened off so the frost won’t destroy it.
- Before the chrysanthemum’s new foliage emerges in the spring, fully prune the plant. Mums benefit from having more leaves on top throughout the winter to shield the plant’s crown.
- Rogue Sage (Perovskia)
- Since Russian sage is a woody perennial, only a moderate pruning to shape them in the early spring is beneficial.
There are several exclusions to the guidelines, as there usually are with gardening:
- Pruning down in the fall, Bearded Iris Although the leaves will still be green, they must be removed since the iris borer’s larvae are found there.
- Decorative Grasses
- When ornamental grasses are left uncut after dying back, they produce stunning winter interest in the garden. If you must trim back in the fall, be sure to wait until they have fully died back. Make sure to prune in the early spring before new growth appears if you do so. For information on how to prune the various grass varieties, click here.
- RosesIf it has to be shaped, leave the rest and only chop down a third. Any severe pruning should be postponed until early spring, right before new growth emerges.
When pruning and cleaning up your garden in the winter, remember to always practice excellent garden sanitation. To try to contain and control the disease, make sure to remove all foliage from the garden and the ground if you know a plant is sick. In order to avoid unintentionally spreading any diseases, you should also routinely clean your pruners with rubbing alcohol or a bleach and water solution.
Although perennials need patience, the reward is definitely worth the effort!
