Whether in the garden or on the balcony, as a perennial in the border bed or as a ground cover: carnations are popular plants because of their wonderful flowers and their intoxicating scent. They are also ideal as cut flowers, as carnations last a surprisingly long time in the vase. However, the flowering time varies depending on the type and variety of carnation, although there are both quite early and late flowering varieties.
When is the flowering time of carnations?
The flowering time of carnations varies depending on the species and variety, with some varieties blooming from May to June, such as the Whitsun carnation (Dianthus gratianopolitanus), while others, such as the carnation (Dianthus caryophyllus), bloom from May to June May bloom in October. Regular care can encourage a second bloom.

Encourage carnations to bloom a second time
The mat-forming species in particular should be cut back after flowering. On the one hand, this makes the overgrown areas look tidier or thicker, and on the other hand, they encourage some varieties to bloom a second time. With so-called repair pruning, you simply remove all dead shoots, although the foliage is left standing unless it has withered. You can also stimulate re-blooming by providing the cut carnations with a little liquid complete fertilizer (€18.00 on Amazon). There are many remontant varieties, especially of the Pentecost carnations and the spring carnations.
Tip
A variant of the carnation, the rare Dianthus superbus var. autumnalis, blooms particularly late.
