Right here’s what’s arising:
What Are Carnations?
Carnations, Dianthus caryophyllus, are a species of herbaceous perennials typically grown as annuals that develop as much as 30 inches tall and kind engaging, spreading clumps or mats.
The fringed flowers of carnations and their hybrids have a radial symmetry with a sweetly spicy perfume of cloves.
The scent is lighter than different Dianthus species akin to Cheddar pinks (D. gratianopolitanus), and plenty of cultivars are fully fragrance-free.
The opposing, slender leaves are a reasonably gray-green or blue-green and make a good-looking contrasting anchor for the color-saturated flowers floating above.
These edible flowers measure one to 2 inches throughout and have a mildly candy and peppery taste. Forming on wiry stems, they develop singly or in teams of as much as 5, with single or double petals.
Cultivar colours embrace vibrant shades of inexperienced, peach, pink, salmon, scarlet, purple, pink, white, and yellow, with some having striped variations or picotee edging.
Most are hardy in USDA Zones 5 to 9 and flower from mid- to late spring into midsummer.
Nevertheless, a number of cultivars give a gentle, however lighter, rebloom via late summer season when spent flowers are deadheaded.
Cultivation and Historical past
Considered natives of the Mediterranean area of southern Europe, cultivation dates again to no less than historic Greek and Roman instances.
The genus identify, Dianthus, is from the Greek phrases for divine (dios) and flower (anthos), which means flower of the gods – clearly, they thought they had been heaven-scent(ed)!
The species epithet, caryophyllus, refers back to the clove scent.
In antiquity, carnations had been utilized in ceremonial crowns, and in some cultures they’re symbolically used to precise love and affection, however with variations relying on the flower coloration.
The three hottest forms of carnations are the tall, large-flowered cultivars most frequently utilized by florists, and spray or dwarf varieties which can be sometimes grown within the dwelling backyard.
Florists’ carnations often have one to a few flowers per stem and sometimes develop 18 to 30 inches tall. Spray and dwarf varieties have a number of blooms per stem and develop between 9 and 24 inches tall.
The Dianthus genus additionally consists of a number of different common backyard species, akin to alpine pinks (D. alpinus), Cheddar pinks (D. gratianopolitanus), China pinks (D. chinensis), backyard pinks (D. plumarius), and massive pinks (D. superbus).
Propagation
Carnations are propagated by root division, seed, or stem cuttings.
Root Division
Root division is an efficient solution to rejuvenate outdated vegetation which can be overcrowded or affected by dieback.
To divide vegetation, in early autumn dig up the complete clump, inserting your spade a couple of inches away from the plant’s perimeter to make sure roots aren’t broken.
Utilizing your fingers or clear, sterile backyard shears, pull or reduce vegetation into smaller sections, fastidiously teasing the roots aside.
Discard the center or older sections in the event that they’re drained or spent, in addition to any items with rotting or tender roots. Every part ought to have a number of wholesome shoots and roots hooked up.
Plant divisions into ready areas, guaranteeing the roots are just under the floor, however conserving the crown and stems above the soil line – keep away from burying the crown as this will likely result in issues akin to crown and root rot.
Stem Cuttings
Skilled growers propagate carnations by rooting terminal flower stem cuttings. Terminal flowers are those that kind on the finish of a stem, not the place the stem and department meet.
Take four- to six-inch cuttings in summer season, ideally within the cool of morning, from non-flowering stems.
Use a clear, sharp knife or scissors to chop just under a set of leaf nodes. Pinch off the underside set of leaves and dip the reduce finish right into a rooting hormone if desired.
Fill four- to six-inch pots or a seed tray with a fine-textured potting combine and push stems into the soil as much as the primary set of leaves, spacing evenly so the leaves of various cuttings aren’t touching.
Gently agency the soil round them for stability.
Water gently however completely to saturate the soil then cowl with a cloche, dome, or plastic bag.
Place in a vibrant, sunny windowsill and maintain the soil barely moist till cuttings have rooted, which ought to occur in about three to 4 weeks.
Each few days, uncover the cuttings for a few hours to permit contemporary air circulation, which helps to stop fungal infections. As soon as new leaves emerge, take the covers off for good.
When the cuttings are rooted and producing new development, repot every stem individually and place in a heat, protected web site within the backyard that’s sheltered from the recent afternoon solar.
Because the temperatures drop, you may transfer them to a chilly body or right into a location that’s protected against frost.
Plant out into the backyard the next spring.
From Seed
To propagate carnations from seed, they are often began early indoors or sown straight within the floor in April or Could – however observe that direct-sown seeds are unlikely to flower till their second 12 months.
For first-year flowers, begin indoors 12 to 14 weeks previous to your final frost date in spring.
Fill seed trays or small containers with fine-textured and well-draining potting combine.
Sprinkle the seeds evenly throughout the soil, then cowl them evenly.
Water gently till the soil is moist then cowl with a cloche, dome, or plastic bag to create a greenhouse impact.
Germination ought to happen in a couple of days. After seeds sprout, take away the covers for a few hours each few days to permit for air circulation.
Preserve the potting medium evenly moist.
As soon as seedlings have two or three units of leaves, in any case hazard of frost has handed, transplant into the backyard or into bigger containers.
To direct sow outdoor, wait till in any case menace of frost has handed.
Put together beds with fertile, well-draining soil and sow seeds one-eighth of an inch deep.
Within the absence of rain, maintain them evenly moist however not waterlogged.
As soon as vegetation are 4 to 6 inches tall, skinny to 10 inches aside.
Develop
Carnations flower finest in fertile, humus-rich soil with a pH of 6.7 to 7.0 in a full solar location – however they do admire some shade in areas with highly regarded afternoon solar.
Put together and enrich the planting web site by amending the soil with compost.
To enhance drainage, add granite chips, panorama sand, or pea gravel – Dianthus should have well-draining soil to keep away from issues like crown and root rot.
Combine in some bone meal to create sturdy, wholesome roots, utilizing one to 2 tablespoons per gallon of soil.
Place vegetation so the crown is simply above the soil after which backfill, firming the soil evenly across the roots.
Water gently and completely, and keep even moisture till established. As soon as vegetation are rising effectively, water them deeply as soon as per week, ready till the highest inch of soil is dry between purposes.
Apply mulches fastidiously and maintain moisture-retentive supplies away from the crown.
Crowding carnations with thick mulches that maintain water can entice an excessive amount of moisture across the crown and in addition inhibit air circulation, which might result in points like crown rot and fungal infections.
For taller varieties that develop as much as 30 inches, a mesh grid netting will be useful to guard the wiry stems from wind injury or flopping.
For container development, Dianthus should have well-draining, humus-rich soil.
Select planters with drainage holes. I like so as to add a two-inch layer of drainage materials akin to damaged pottery or pebbles to the pot earlier than filling it with soil – this helps to stop soggy roots and related issues.
Enrich the container soil with compost or well-rotted manure and amend with drainage supplies like coarse panorama sand or granite chips if wanted.

In early spring, feed bedding vegetation and containers with a slow-release granular fertilizer or feed with a water-soluble utility month-to-month from early spring to mid-August.
Use an all-purpose method akin to 20-10-20 NPK.
An alternate is to use a two-inch layer of compost in early spring, raking it gently into the soil across the root zone. Take care to maintain compost away from the crown to keep away from impeding air circulation.
Taller species can profit from staking ought to they develop into top-heavy with flowers. Use any sort of stakes akin to bamboo, or ones with an adjustable hoop to simply management flopping flowers.
These Peacock mini-stakes with a sliding, eight-inch ring are best. They’re accessible from Gardener’s Provide.
Peacock Mini Plant Assist Rings
An alternative choice for staking tall cultivars is to run a 12-inch part of netting between a couple of anchoring stakes, weaving the web between vegetation for assist.
Place the netting so the highest edge is a couple of inches beneath the flower buds.
Nylon Trellis Netting
Nylon trellis netting that’s simply reduce to measurement can also be accessible at Gardener’s Provide.
Dianthus species are pretty short-lived and profit from division each three to 5 years to rejuvenate vegetation.
To divide vegetation, use the identical steps which can be outlined within the Root Division part above.
To gather seeds, don’t deadhead the final spherical of flowers and permit the spent flowers to kind seed heads.
To keep away from dropping the small seeds, reduce the stems earlier than the pods dry out fully, then end drying indoors in a heat, dry setting.
It’s also possible to invert a small paper bag over the seed heads and safe it in place with twine or an elastic band.
As soon as the pods are dry, reduce the stems and switch luggage proper facet up. Give them shake to gather the seeds within the backside of the bag.
A kitchen sieve is a helpful help for separating seeds from the petal and pod chaff – maintain it in your backyard tote for small-seeded vegetation like basil, carnations, and snapdragons.
For full, vibrant clumps with new volunteers every spring, use a few of the final spherical of flowers for self-seeding.
In fall when the seed heads are dry however not totally open, depart them to unfold on their very own or crush the pods and sprinkle the seeds generously the place they develop.
Not all carnation cultivars are self-seeding, however many are. To limit volunteers, for those who’d desire, remember to diligently deadhead after flowering.
Take away useless or spent supplies and trim vegetation by as much as one-third by mid-autumn. Clear beds of useless or decaying materials earlier than winter to discourage overwintering of unfriendly pathogens.
To guard vegetation from winter chilly, use solely free-draining mulches like pea gravel – heavy, water-retentive supplies can result in points like crown and root rot. Cowl the foundation zone with two to 4 inches of gravel however depart the crown clear.
