Care Guide

💧

Watering

Carnations (Dianthus 'Supra Purple') should be watered every 7 to 10 days unless the soil is already very moist. Water the plant slowly and deeply so that the water reaches the roots. Avoid overwatering the plant; if the soil is soggy or muddy, wait another day or 2 until it has dried out before watering again. Allow the top inch of soil to dry out before watering again. During the warmer months when the plant is actively growing, you can increase watering frequency to every 3-5 days.

☀️

Light

Carnation (Dianthus 'Supra Purple') requires full sunlight for optimal growth. This means the plant should be in direct sunlight for at least 5 to 6 hours a day. More sunlight means the plant will bloom for a longer amount of time. To ensure that the carnation receives enough sunlight, try to place the plant in an area that receives direct sunlight for most of the day. Make sure to rotate the carnation every few days so that all parts of the plant can receive light.

Pruning

Carnations of the Dianthus 'Supra Purple' variety should be pruned according to their flowering cycle; when the flowering period is complete, usually in the spring or early summer, the stems can be cut back by about half of their length, ensuring that the leaves are also trimmed away. In late summer, any weaker, less healthy stems can then be removed. Deadheading of spent flowers should be carried out at least once a fortnight to promote fresh growth and to help the plant to remain healthy. After a few years of regular pruning, any weak or dead stems, as well as any discoloration, can be removed in the spring or summer to help keep the plant looking vibrant and blooming.
