Dianthus is a highly diverse genus of flowers that all share a range of charming characteristics sure to recommend them to any garden. Blooming in shades ranging from lilac to deep pink, dianthus is the perfect flower for bringing both early and late splashes of colour to your garden, blooming first in the spring and again in the autumn.

Alpine varieties of dianthus are hardy enough to cope with cold and fast-draining soil but do keep in mind that all dianthus require sunlight, not coping terribly well with shade. A mainstay of British gardens for some time, the popularity of these flowers derives not just from their bewitching scent, but also from their ability to attract butterflies and bees, bringing some palpable life to your garden.

There is a range of myths explaining how they came to be prominent, and it would seem that they have never lost that high reputation. The best time to plant pinks and other varieties of perennial or biennial dianthus is early spring. They work well particularly well in borders as the vertical ascent as they grow can be seriously eye-catching. You can grow from seeds or cuttings started indoors.

Choose a soil with a good amount of well-rotted compost or other organic matter worked in at a depth of around twelve inches. Grow pinks in well-drained compost in full sun. Cut back after flowering to encourage a second flush of blooms, and feed with a liquid tomato feed.

Cut back again in autumn. Dianthus are not long lived plants — after a few years they go woody at the base and look rather straggly. They are easily propagated by cuttings, however, so you can create fresh plants each year. They can last for a couple of weeks in a cool room. Pinks are hardy and cope well in hot summers and very cold winters. They do best in a neutral or alkaline soil. An open position is beneficial and a well-drained soil is essential. Pinks require a well-drained soil.

Improve heavy soils by digging in grit prior to planting. Alternatively plant pinks in pots of peat-free, multi-purpose compost. Alpine pinks are perfect for pots. Deadhead spent blooms and feed with a liquid tomato feed to encourage a second or even third flush of flowers. Some of the very old-fashioned pinks might not flower more than once a year. In autumn cut back the faded blooms and any leaves that look scruffy. Lightly trim the foliage to encourage fresh growth. You can take cuttings each year to keep a fresh supply of plants going.

Dianthus are shortlived plants, so cuttings are a good way of keeping your plants going. Continue to grow the seedlings indoors until they've reached 4 inches tall. They can be then planted outdoors once all risk of frost has passed. One of the biggest issues dianthus plants have is vascular wilt. Characterized by dull green stems that droop and eventually dry out, wilt is technically a fungus that can eventually kill an entire plant. Treatment is difficult as fungicides are not effective—therefore, it's important to rotate your plantings frequently and avoid planting in any soil that seems diseased.

Additionally, dianthus plants may have issues with other common plant pests, such as spider mites and aphids. To treat, you can apply insecticidal soap or neem oil until all signs of an infestation are gone. Lucky for many gardeners, dianthus plants are easy to care for and rarely have trouble blooming. Still, if you're having trouble getting your plants to show off, there are a few things to keep in mind. First and foremost, dianthus plants should be located somewhere that gets at least six hours of bright sunlight daily.

Too little light can impact the frequency and vibrancy of the blooms. Additionally, ample water is important for the overall health and blooming of dianthus plants. Ensure that the soil doesn't get dried out with frequent weekly watering—you can also mulch over the soil around the roots of the plant to lock in moisture and prevent evaporation.

Finally, proper grooming is essential to encouraging dianthus plants to bloom. By frequently deadheading the spent blooms, you'll invite the plant to produce more buds and foliage, rather than put energy into turning the spent flowers into seed.

As long as they're given the proper growing environment, dianthus plants are easy to care for and perfect for beginner gardeners. Dianthus plants can be started indoors when growing from seed or being propagated, but most dianthus plants are typically grown outdoors long-term.

Dianthus plants grow very quickly. Seedlings can emerge in as little as eight days, and a new plant can be fully in bloom in under three months. North Carolina State University. Dianthus deltoides.
