Due to their frugality, the various types of carnations are ideal for cultivation in pots. Only wintering could be difficult. Not because the plants are too sensitive to frost. No, they usually shrink due to too much moisture. In this article you will learn what you should pay particular attention to when it comes to potted carnations.
How to grow carnations on the balcony?
Carnations thrive on balconies in pots when planted in a sunny location with well-draining, well-drained substrate. Low-growing species such as Whitsun carnations, spring carnations or sand carnations are particularly suitable. Be careful to avoid waterlogging.
Sunny location preferred
All types of carnations need a sunny to full sun place with permeable, moderately moist and neutral to slightly alkaline soil - with one exception: the heath carnation (Dianthus deltoides) is the only species that prefers slightly acidic soil. You can mix the right substrate yourself with sand, potting soil and some clay granules, with the latter primarily being the first layer on the bottom of the pot. The clay granules (you can also use potsherds or similar) should drain excess water from the pot and thus ensure good drainage.
Care for carnations in the pot properly
Drainage is extremely important because carnations love dryness and should never be too moist. Wet winters in particular are fatal for the plant, as they often develop waterlogging and thus rotten roots. Apart from that, carnations are very easy to care for because you should not fertilize the plants, which are usually one to two years old. Pruning is basically not necessary unless you want to encourage the carnations to bloom a second time. Apart from their sensitivity to moisture, carnations are considered to be very winter and frost hardy.
Species particularly suitable for pots
The rather low-growing species such as the cushion-forming peony carnations (Dianthus gratianopolitanus), feather carnations (Dianthus plumarius) or sand carnations (Dianthus arenarius) have a much easier time over the winter. So-called hanging carnations are also available in stores especially for balcony boxes, which usually belong to the Dianthus caryophyllus, the garden carnation or noble carnation.
Tip
Carnations are wonderful cut flowers that last a long time in a vase. You can also extend its shelf life by changing the water in the vase every two days. If possible, only cut stems lightly - but not completely! – opened flower buds.
