This attractive plant grows carefree and can tolerate practically any soil. It prefers soil that is humus-rich, loamy, a bit damp, and well-drained—not waterlogged or too saturated.
Cranesbills flourish in the soft shadow provided by high treetops, and they will grow best in areas with morning sun or partial shade.
A perennial with a long lifespan, its growth is modest in the first few years. The spectacle these plants put on, however, lasts from late spring through October after a mound has formed.
Furthermore, they gain from routine deadheading. By mid-summer, growth may be sluggish in some cultivars, and your chubby, attractive mound may appear somewhat worn out and lanky.
To renew, reduce the mound by half to promote fresh blooms and extend the growing season. To keep some blossoms while new growth develops, shear the plant in two, about two weeks apart, or do it all at once.
Seed collection, stem re-rooting in water, semi-ripe wood cuts in the summer, or root division in the fall or spring are all methods of propagation.
For blooms the next season, collect seeds all through the summer and then sow them in the spring or early summer.
Although deadheading keeps the plant compact, it also results in the loss of seedheads. Allow some pods to stay on the plant to mature in place if you want to start plants from seeds.
Cranesbill is one of the plants that may form roots in water due to stem rooting.
Recall all the teacups your grandmother had on her windowsill filled with plant cuttings? They might have been geraniums, for sure!
Cut the stem right below the node where the leaves join the stem with a sharp knife to ensure strong, healthy roots. Leave the top two or three leaves in place and remove the lower leaves. Remove all blooms as well; energy should be used to produce roots rather than seeds.
Put a number of cuttings in a clear container of water, and change the water as needed or every few days. In order to protect and shade the tender new roots, which typically emerge in 3–4 weeks, use an opaque container.
Place the container containing the cuttings on a bright windowsill or in a protected area of the garden that receives 2 to 6 hours of soft sunlight each day. The finest lighting is early morning or dappled shade.
Plant as for stem cuttings below once healthy roots reach a length of about 1-2 inches.
This year’s growth is chosen for the semi-ripe wood. The cuttings’ tips are still sensitive and green, but their bases will be older and harder. From mid-summer until mid-autumn, semi-ripe wood can be harvested whenever it is available.
Put root divisions and stem cuttings in little pots with a light, sandy potting soil. For a period of one to two years, or until they are old enough to be buried, you can also place them in a nursery bed.
Spreading of cranesbill geraniums?
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. As a general rule, they tend to do best in early morning and afternoon sun, although some, such as Geranium sanguineum and Geranium pratense and their varieties thrive in full sun, providing there is adequate moisture in the soil.
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
- Clarkei Kashmir White Geranium
- Red geraniums
- Theodora Mavis Simpson
- Ingersoll Orion
- The Mrs. Kendall Clark geranium
- Wageningen’s Geranium x oxonianum
- Renardii 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.
Size & Growth
Although the height of cranesbills varies depending on the species, they often fall under the category of higher shrubs and can grow anywhere between 12 and 20 inches in a year.
However, they have a spread of typically between 18 and 24 inches and are mounding plants.
Although the plants are native to temperate regions, they are extensively grown under similar circumstances all over the world.
Hardy geraniums can be identified by their dark green, citrus-flavored leaves, which is why they are sometimes called scented geraniums.
These plants’ autumnal foliage, which consists of a mixture of brown, golden, burnished bronze, and red hues, produces a stunning display.
Flowering and Fragrance
Beautiful flowers in white, purple, magenta, lilac, blue, violet-blue, and pink hues are produced by the plants in the summer.
The blooming season for many cranesbill species begins in late spring and lasts into late October.
These geranium types are a popular choice for gardens because of their lovely bloom hues.
Light & Temperature
True geraniums thrive in full sun, but they also like midday part shade.
The optimum locations for these plants are those that provide them with morning sunlight and afternoon mild shade.
Watering Requirements and Feeding
However, be careful not to overwater as they cannot thrive in soil that is saturated with water or has standing water.
When the new foliage is just beginning to emerge in the early spring, the flowering perennial plant species benefit from a yearly feeding with a balanced 10-20-10 fertilizer.
After mid-summer deadheading, the fertilizer should be administered again as soon as the plants begin to produce new growth.
These geranium species shouldn’t receive any more fertilizer than this because excessive fertilization frequently results in sprawling and lanky growth.
