In order to give the plant enough time to establish its roots before a frost, divide the geraniums in the early spring to early summer. Shake the earth off the plant’s roots by digging it up. Make divisions with a trowel or knife, being careful to include a root section and leaves in each division.
When may I have a cranesbill transplant?
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:
- Ann Folkard, geranium
- (Cinereum Group) Ballerina named Geranium

- 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.
How well do geraniums transplant?
Whether they are nursery plants moved to a garden or unusually colorful plants saved from winter freezes by being taken indoors, geraniums (Pelargonium spp.) transplant easily, provided they get plenty of moisture and light after their move.
Do you prune tough geraniums?
Hardy geraniums require hardly any maintenance. Rabbits don’t seek them, while slugs and snails prefer to consume other plants. After their initial flowering, they can be trimmed right back to the ground, and the next summer, they will produce new foliage and additional blooms. Avoid cutting back too soon after flowering because some hardy geraniums have lovely autumn leaves.
Propagating hardy geraniums
Hardy geraniums don’t typically need to be propagated because seedlings may be easily removed from the garden and potted up. In the spring, plants can be lifted and divided. Hardy geraniums can be challenging and time-consuming to grow from seed.
Growing hardy geraniums: problem solving
Geraniums that are hardy are generally trouble-free. However, the geranium sawfly larvae have been known to attack them (Ametastegia carpini). These appear to be 12mm long, small grey caterpillars. They leave unattractive lace-like holes in the leaves after they eat them. In your garden, the more resilient geraniums you have, the more probable it is that they will reproduce.
Since they fall off the leaves when the plant is disturbed, the larvae might be challenging to see. The months of May and September see the most activity; the September generation pupates in the soil and spends the winter there before emerging in the spring to deposit eggs on the foliage. Even though the damage can be extremely unattractive, the plant rarely becomes less vigorous as a result. The following steps could assist in keeping them in check:
- Many geranium sawfly larvae overwinter in the soil, therefore clearing away debris and lightly raking the soil beneath vulnerable plants will expose the larvae to the elements, where they will be killed by frost and devoured by birds and other predators.
- From May on, carefully inspect the undersides of leaves for signs of the eggs and larvae and remove them by hand if possible to prevent numbers from growing.
How is a cranesbill transplanted?
Hardy geraniums, also known as cranesbill geraniums, are perennial flowering plants that get their name from the long, slender seed heads that resemble a crane’s beak. Cranesbills are real geraniums that grow well in U.S. Department of Agriculture plant hardiness zones 3 or 4 through 8, depending on the cultivar, in contrast to the zonal, annual geraniums that are members of the Pelargonium genus. For gardeners looking for simple-to-grow, low-maintenance plants that consistently bloom for several weeks, these hardy, adaptable plants are fantastic options.
Pick a place for your plantings that receives full sun to some shade. Cranesbill geraniums favor locations with adequate drainage and healthy, moist soil. In regions where summers are scorching, these plants prefer a little midday shade.
Place your cranesbill in a location with lots of space for it to expand. Your plant will have a comparable spread and reach a height of 6 to 30 inches, depending on the type. Geraniums should be placed as widely apart as the widest mature size of the cultivar.
Before planting, add organic matter to the soil, such as compost. This feeds your plant and aids with soil moisture retention. If you want the soil to drain better, add perlite to it.
During the first year of growth, give your geraniums enough water to keep the soil constantly moist. But beware of too much dampness; it can soon create root rot. Once the plant reaches maturity, the majority of cranesbill cultivars are drought tolerant, therefore water only when a prolonged drought occurs.
During hot, humid conditions, check your plant’s leaves for leaf spot infections. With cranesbill geraniums, leaf spot is rarely a major issue, but removing affected plant tissue to a height of 6 to 8 inches encourages the establishment of new, healthy plant tissue.
In the spring, divide big cranesbill geranium plants. To remove a side shoot with sound roots, carefully excavate on one side of the plant clump. Quickly replant the new division.
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.
Can tough geraniums be moved?
A. For the past four years, my enormous, sturdy geranium plant has produced gorgeous blooms. I want to split it apart. When should I do this and how?
A. Early spring is the ideal time to dig, divide, and transplant true perennial geraniums. On a chilly day, dig up the entire plant. Water the plant well before digging and, of course, after planting if the spring has been especially dry.
Cut the clump into two, three, or four equal pieces using a sharp spade, shovel, or pruning saw (if the plant is especially huge). Each part should be replanted in the same sun/shade circumstances as the parent plant, in well-drained soil.
Plant your divisions where they will have enough room to spread since perennial geraniums have a mature width of 1 to 2 feet. They flower from May to June, therefore there may be a minor reduction in flowering during that time. Water the plants thoroughly, especially in the first year after moving them.
What may cause the flowers in my containers to get chewed-ragged, with torn petals and leaves? Although I haven’t seen any, I suppose it’s an insect.
A. Earwigs destroy flowering plants in garden beds and containers in the summer in a manner similar to what you describe. When you’re not looking, they will also eat entire flower heads, buds, and stems. Because they are nocturnal and spend the day hiding under moist mulch, flower pots, garden stones, garbage, etc., you hardly ever see them feeding.
Stronger chemicals should not be used because of their protective shell-like coating, which shields them from insecticidal soaps. As with slugs, luring and trapping can help with management. As soon as you see evidence of damage, moisten a rolled-up newspaper and place it next to the container or in the garden. Check quickly in the morning to see if they are concealed within or beneath the paper, and then get rid of them in a basin of soapy water.
Q. I’ve had golden pothos houseplants for years, but I’m now experiencing issues and am unsure of the cause. The leaves are turning black and falling off. Any thoughts?
A. Golden pothos, or Epipremnum aureum, is a common houseplant since it requires little maintenance and has few insect or disease issues. However, healthy indoor plants that have been grown for years in the same potting soil and have received little fertilizer may start to deteriorate.
It might also benefit from a 1-inch larger container filled with fresh potting soil and some soilless mix, as well as a monthly dose of a balanced houseplant fertilizer used during its active growth months.
You can encourage Pothos, a climber, to have a stockier growth habit by pinching back the growing tips. Even moisture is needed in the spring and summer, but allow the soil to dry out more in the fall and winter. If the plant is overwatered in the winter, it may develop dark patches, blotches, or entire leaves.
