Carnation Dianthus 'Peter Wood' (b)

Water

For the Sweet William, water thoroughly but allow the top inch of soil to dry out between watering sessions, typically about once a week. Use approximately 1 gallon of water for outdoor plants each time you water, adjusting for rainfall and temperature conditions. During hot, dry periods, an additional watering may be necessary to maintain consistent moisture. Over-watering can lead to root rot, so it's important to ensure good drainage and not to let the plant sit in waterlogged soil.

Light

Sweet William thrives in full sun conditions with at least 6 to 8 hours of direct sunlight daily. It's best to position the plant in a south-facing bed or border for optimal light exposure. However, in extremely hot climates, some afternoon shade can help prevent scorching of the foliage and blossoms.

Temperature

Sweet Williams prefer temperate climates and can generally withstand a range between 40°F and 85°F. They will survive brief periods of colder weather down to about 20°F but may need protection from frost. The ideal growing temperature for Sweet William is between 60°F and 70°F.

Pruning

Prune Sweet William to encourage bushier growth and more abundant flowering. Deadheading, or the removal of spent flowers, should be done regularly to promote continuous blooming. After the main bloom period, cutting back the stems can stimulate a second flush of flowers. The best time for substantial pruning is late winter or early spring before new growth begins.

Cleaning

As needed

Soil

Sweet William, or Dianthus 'Peter Wood', thrives in well-draining, loamy soil with a neutral to slightly alkaline pH of about 6.5 to 7.5. A soil mix with equal parts garden soil, sand, and compost provides the ideal texture and nutrients. Regular fertilization can help maintain soil fertility but ensure good drainage to prevent root rot.

Repotting

Sweet William should be repotted every one to two years to replenish nutrients and prevent it from becoming root-bound. Repot in spring before new growth begins for less stress on the plant.

Humidity & Misting

Sweet William prefers moderate humidity conditions. While it can tolerate a wide range of humidity levels, try to maintain it in an environment that is not too dry, avoiding overly humid conditions that can encourage fungal diseases.

Suitable locations

• Indoor

  Place Sweet William in a sunny spot with good air circulation indoors.

• Outdoor

  Plant Sweet William in full sun with well-draining soil.

• Hardiness zone

  3-9 USDA

Life cycle

Dianthus 'Peter Wood', commonly known as Sweet William, typically starts its life cycle as a seed that germinates in the spring under the right conditions of moisture and temperature, developing into a young seedling. The plant then grows into a clump-forming perennial with narrow, lance-shaped leaves, entering a vegetative stage where it puts on much of its foliage. As temperatures increase in late spring to early summer, it transitions to the flowering stage, producing clusters of fragrant flowers that attract pollinators. After pollination, the flowers develop into seed capsules, and once the seeds mature, they are dispersed by wind, gravity, or other means. After flowering, if not deadheaded, the plant may enter a period of dormancy, especially in regions with cold winters, where it conserves energy to survive until the following spring. Throughout its life, Sweet William can also be propagated vegetatively via cuttings or division to create new plants that are genetically identical to the parent.

  Spring-Early Summer

• The Dianthus 'Peter Wood', commonly known as Pinks, is commonly propagated through the method of cuttings. This is often carried out during late spring or early summer when the plant is actively growing. To propagate Pinks through cuttings, one selects healthy, non-flowering shoots and cuts a piece about 3 to 5 inches long just below a node. The lower leaves are removed, and the cut end can be dipped in rooting hormone before planting in a well-draining soil mix. The cuttings should be kept in bright, indirect light and maintained at a consistent moisture level. Roots typically form within a few weeks, after which the new plants can gradually be acclimated to outdoor conditions and eventually transplanted into the garden.
