Dianthus Plant

 

Dianthus Plant

     Plant Profile

  • Plant family: carnation family (Caryophyllaceae)
  • Type: carnations
  • Origin: temperate northern hemisphere
  • Herbaceous, persistent, cushion-forming annual or biennial plant
  • Growth height: depending on the kind between 20 centimetres and 70 centimetres
  • Blossom period: depending on the kind from May to August
  • Colour: white, pink, red, magenta, neon yellow, champagne, purple and two-coloured
  • Sepals on tall, simple or branched stems
  • Perennial
Dianthus Plant The dianthus plant is also called Sweet William (Dianthus barbatus) and has a fragrance with cinnamon or clove notes. The plants are small and usually between 6 and 18 inches (15-46 cm.) tall. Dianthus flowers are most often in pink, salmon, red and white hues. The foliage is slender and sparsely spread on thick stems. Dianthus had a short blooming season until 1971, when a breeder learned how to grow forms that did not set seed and, therefore, had a prolonged their bloom period. Modern varieties will typically bloom from May to October.

The plants need fertile, well-drained soil that is alkaline.

Care

Carnations, dianthus don’t need much or intense care, but there are still some details that need to be kept in mind in order to ensure the best growth possible.

Location

The carnation, dianthus likes sunny, wind-protected locations, which enable it to develop nicely. This applies to growth as well as colour intensity and odour development. If you choose a half-shaded place, the carnation will become less opulent.

Soil conditions

No matter if in a flowerbed, flower tub or balcony trough: it’s important to choose the right soil conditions in order to get vital and blossomy carnations.

  • humous, nutrient-rich soil
  • moderately damp
  • permeable
  • mainly chalky soil
  • neutral pH-number below 7.0

Dianthus Flowers in the garden

The maiden pink (Dianthus deltoides) is an exception. Those also like slightly sour soil. Carnations (dianthus) are sensitive to too much humidity. That’s why they should not be planted next to other plants that require much water. They should not be put near streams or rivers either, because those areas are often permanently damp. The fringed pink (Dianthus superbum) is one of very few carnations that enjoys humidity.

Substrate

In order to provide the optimal basis for growth, health and blossom, substrate is generally recommended. Should carnations decorate a flower tub or box, high-quality flower soil is necessary. It supplies carnations with nutrients they need for ideal prosperity. They will be more resistant and durable. Substrates that contain natural clay, bark mulch or wood fibre provide the perfect soil airing. White peat and perlite support the structure’s stability.

Planting

The perfect time to plant carnations is spring or autumn. Soil frost should be over in springtime and not yet arrived in autumn. If there is unexpected frost anyway, a protection foil could shelter the plants.

Plants in flowerbed

It’s necessary to prepare the soil properly to ensure that the carnations develop stately. It should be aerated with a rake first. Secondly, a hole for the plant can be dug. Stones or old roots need to be removed. It’s recommendable to add quartz sand, because it improves permeability and enables water to drain.

In addition, the soil should be mixed with compost or high-quality substrate. This will improve the carnation’s powerful growth. If there’s not enough chalk in the soil itself, some of it should be added as well.

This is how you should proceed:

  • depending on which carnation, you need to dig holes at a distance of about fifteen to thirty centimetres
  • put approximately three centimetres of quartz sand into the holes in order to create drainage
  • the hole should be twice as deep as the root ball’s size and there needs to be a three centimetre gap between roots and soil surface
  • mix the soil with substrate or compost and refill the hole
  • press the soil firmly
  • finally, you can water it slowly and moderately

Plants in a flowerpot

Planting carnations into flower tubs or balcony troughs works the same way as planting them into the ground. It’s important to use high-quality substrate, which provides carnations with the ideal basis for growth. Instead of quartz sand, it is also possible to scatter shards of earthenware on the ground, which works as drainage. You should make sure that there is a minimum distance of 2 centimetres between soil and the flower pot’s or box’ edge.

No water will spill over it when you water the flowers, even if the soil becomes muddy. It’s recommendable to use a saucer, which collects remaining water and prevents waterlogging if kept dry. Moisture-sensitive carnations will develop better.

Watering

Most kinds of carnations dislike dampness and manage well in dryness. That’s why they should only be watered moderately and not until the soil is almost completely dry. You can easily test that by pressing your thumb into the flower soil. If you can’t push it deeper than two centimetres, you can water the flower.

Manuring

Although carnations don’t need much care, they enjoy manure. An organic start fertilizer is recommended when replanting or repotting fully-grown carnations. Apart from that, complete fertilizer should be added before blooming time in spring. After pruning back the sprouts and before a new blossom period, mineral fertilizer advisable. It should be used sparingly, because carnations are light feeders.

Overview over manuring periods:

  • start fertilizer when replanting or repotting
  • complete fertilizer in spring
  • mineral fertilizer after pruning back
  • providing carnations in flower pot or balcony trough with liquid fertilizer every 4 weeks
  • after manuring, flowers should be watered moderately; use chalky water if possible

Cutting

Withered stems and blossoms should be cut away as soon as possible. They use up too many nutrients, which are needed for new blossoms. Consequently, the flowers will have fewer blossoms and existing ones will wither sooner.

The same applies to brown leaves, which can easily be removed. Normally, they just fall off when leaves turn brown. At the end of each blossom period, you can cut the flowers by maximal one third. This improves regrowth and appearance. Pruning back is recommendable if the plant has thin spots.

Dianthus with white blossoms

Carnations are beautiful cut flowers and look great in any vase. Two or three centimetres above earth’s surface, the flower’s stem can be cut off. This should be done when the blossoms are still slightly closed. However, don’t cut them off in summer’s hot midday sun. The cut surfaces show open pores and heat will damage the flower.

Overwintering

Most kinds of carnations are hardy until 15 degrees below zero. Humidity can still damage them when snow and soil frost drench the soil. Carnations in a flowerpot should be placed somewhere protected from the wind. It’s not advisable to put flower tubs on the ground. They should rather stand on polystyrene. It isolates carnations from cold soil frost.

Carnations in the garden get more than enough humidity through the ground in winter while the dampness of pot carnations needs to be controlled regularly and watered if needed. You should only water them when there is no frost.

Propagation

Carnations are either annual or biennial plants. That’s why it’s necessary to remember propagation in time.

Cuttings

The easiest and most uncomplicated way is the propagation through cuttings. Cuttings of strong plants are cut at an angle and put into a pot with a mixture of peat and sand in it. Perfect cuttings have no blossoms, but at least three leaf nodes. The only thing you need to keep in mind is to water in a steady manner. The roots need rather humid soil to develop. Waterlogging, however, is to be avoided.

  • planting time for cuttings: late summer or autumn
  • time for root development: about eigth weeks
  • after approximately eight weeks, you can plant the cuttings into the flowerbed
