  • water dropWater

    For the Sweet William, water the plant deeply once a week, ensuring that the soil is moist but not waterlogged. This translates to roughly 1 gallon for outdoor plants and 8-16 ounces for potted plants, depending on the size of the pot and the environmental conditions. During hot, dry periods, you may need to water more frequently, while in cooler or rainy seasons, watering can be reduced. Avoid overhead watering to prevent disease, and instead water at the base of the plant. It is important to let the top inch of soil dry out before watering again to encourage strong root growth.

  • sunLight

    Sweet William thrives in full sun to part shade conditions. The ideal location would receive at least 6 hours of direct sunlight daily, although they can tolerate some afternoon shade, especially in hotter climates. Avoid placing them in deep shade as this will diminish their vibrant blooms and overall health.

  • thermometerTemperature

    Sweet Williams prefer cooler temperatures and can survive in a temperature range of 40°F to 85°F. They can tolerate some frost and are generally hardy down to about 20°F. The ideal temperature range for growing Sweet William is between 60°F and 70°F. During extreme heat, the plant may go dormant or experience stress, so providing some afternoon shade can be beneficial.

    Prune Sweet William to encourage bushier growth and more blooms. After the initial flowering, deadhead spent flowers to promote a second bloom. In late fall, cut back the foliage to a couple of inches above the soil line to help prevent disease and to tidy up the plant. Pruning is generally done on an as-needed basis throughout the growing season and more thoroughly during the plant's dormancy.

  • circleLife cycle

    Dianthus 'Tamsin' (p), commonly known as 'Tamsin Pink', begins its life as a seed, which under proper conditions of moisture and temperature, will germinate. Upon germination, the plant starts the vegetative stage, with seedlings developing roots and shoots that grow into stems and leaves. As the plant matures, it enters the flowering stage where it produces distinctive pink flowers with a sweet fragrance, which are pollinated by insects to ensure fertilization. Following pollination, the flowers develop into capsules containing seeds, marking the plant's reproductive stage. Seeds are then dispersed, either by wind, animal, or human activities, completing the cycle. In suitable climates, Dianthus 'Tamsin' can often survive winter and enter a period of dormancy before regrowth in spring, thereby behaving as a perennial.

      Spring to summer

    • The popular method of propagating Dianthus 'Tamsin', commonly known as the Scent First® Tamsin Pinks, is through cuttings, particularly during the late spring or early summer months when the plant's growth is most vigorous. To propagate, a gardener should begin by selecting healthy, non-flowering stems from the Scent First® Tamsin Pinks and cut a piece about 4-6 inches (10-15 cm) in length. The lower leaves are then stripped off, and the cutting is dipped in rooting hormone to encourage root development. This prepared cutting is then planted in a well-draining soil mix, ensuring that the leaf nodes (from where the leaves were removed) are buried as these areas are where the roots are most likely to develop. The cuttings should be kept moist and in a warm environment with indirect light until roots have established, after which they can be transplanted into individual pots or into the garden.
