Re-blooming is aided by removing old blooms from all species of dianthus. They must, however, avoid moist winter soil, as this will cause their roots to rot. They are drought tolerant to some extent, but they do require frequent watering and feeding to maximize flowering. This has no negative impact on the plant.

There are hundreds of species of Dianthus but most good garden centres stock either Carnations, Pinks or Sweet Williams, although very similar there are some subtle differences between the three. The good news is all three Dianthus species are easy to grow and maintain — just follow our growing guide.
Dianthus can be grown in containers, but we recommend adding coconut coir and either perlite or vermiculite to aid drainage and moisture control. Containers should have drainage holes at the base and preferably you should raise them off the ground with feet.
Compacted waterlogged soil can lead to stem and root rot so try to aerate heavy clay soils with additives where possible. In addition to locating Dianthus in well-draining fertile soil, do place them in a sunny position if possible. While Dianthus will cope with a partially sunny spot, they prefer at least 6 hours of sunshine per day.
Dianthus are generally considered frost-resistant but as with many plants, may suffer during a particularly hard frost. Dianthus should never be allowed to sit in waterlogged soil as rot root is the number one cause of plant failure. After planting out, water the plant regularly until established and growing well. You can water more frequently provided the soil is very well-drained.
Avoid overhead watering to prevent crown rot, which is a common problem across all Dianthus species. Water from the side and avoid splashing the centre of the plant. This is especially important if the Dianthus has been planted in a shaded location where the excess water may not evaporate. Shaded areas are fertile ground for fungal diseases which spread by overhead watering and splashing. Dianthus prefer a fertile growing medium, so for optimal growth and blooming, apply a general garden fertiliser at the time of planting and then every 4 weeks during the spring and summer.
For plants grown in small containers, fertilise lightly every fortnight. As an alternative, you can bed in well-rotted manure once a year in the spring. Most Dianthus plants will bloom from spring to late summer, but you can extend this with regular deadheading. Many species of Dianthus, such as Passion a Pink suffer from heavy flowers often several on the end of each stem which causes the stems to bend right down to the soil. Regular deadheading and tidying up the plant by pruning back long stems should help to keep the plant looking neat and compact and may also extend the flowering period into the Autumn.
You can prune Dianthus anytime from mid-spring to Autumn if it needs a general tidying up. Aggressive pruning, down to a neat mound, can be done at the end of autumn.
Dianthus plants are very resilient, and most garden pests tend to ignore them; however, problems usually arise when the plant is overwatered or located in a shaded location.
Stem, root and crown rot are the most common reasons for Dianthus to fail, but in general, Dianthus is easy to maintain and still a great choice for beginners or those with limited time for their gardens.
There are few pests to worry about, and most of them can be treated with commercial pesticides. Dianthus can be annual, which means they only live for one year, biennial, which means they live for two years or perennial; i. To keep your Dianthus collection looking healthy and producing plenty of colourful blooms, we suggest regular splitting and propagating. Use a flowering fertilizer. A liquid, water-soluble or granular fertilizer works well, but reapplication rates differ, so use the package label as a guide.
