Selection of the Planting Site

Damp environment can curb the growth of the plant and increase the risk of diseases, so make sure that the place is airy. Don't place them very close to other plants, especially fast-growing plants.


If you want the plant to grow fast, ensure that the soil is fertile and well-drained. Soil should be a bit alkaline with 6.75 pH. Though this plant may grow well in well-drained sandy soil, it is best to add rotted leaves, compost, pine needles or materials that may retain moisture and nutrients.
You can add a two inch layer of compost and manure on the surface of the soil. Use a shovel to mix it in the soil.


You could grow it by sowing seeds or transplanting. Some of the perennial flower varieties can be grown by tip cuttings, layering or division. Seeds can be sown in the spring season. You could also sow them in your garden in early summer.
Sow the seeds about 1/8 inch deep in the soil. The soil should be well-drained and the planting site should receive a lot of sun. Cover the seed with soil and water the plant to moisten the soil.


Though these plants are hardy, these do not like excessive humidity. You may water it from time to time during dry summer. It would be best to water it in the morning. Do test the soil for moisture during the summer season. Water it if the surface looks dry.
Insert a finger to see if the soil is moist. Don't water if the compost seems to be moist. Excessive watering can cause root rot. It can also cause yellowing of the foliage. You will not need to water the plant very often during the winter season.


Well-rotted manure must be used at the time of planting. A balanced fertilizer which has nitrogen, phosphate and potassium in equal ratios should be used to enrich the soil. You also need to replenish the soil with fertilizer during the bloom season.
Use a fertilizer that is rich in potassium to encourage prolific flowering. This will strengthen the stems and the blooms will be brighter and prettier.

Disbudding and Pruning

If you see 8 or 9 pairs of leaves, pinch off the growing tip. This allows growth of side shoots, stems.
Pinching the shoots will encourage prolific flowering. If you ignore this, the number of blooms would be less. If you wish to get bigger blooms than getting many blooms, remove the surplus buds from the plant. Get rid of the thin side stalks frequently. This will allow the crown bud to develop on each flowering stem.
You should prune and cut foliage in every spring. Most of the spent or faded blooms should be removed, but you could leave a few spent flowers if you want them to produce the seed.
These were instructions that should be followed by those who wish to grow dianthus. If you follow these instructions, you will soon be able to see beautiful and fragrant flowers in your garden.
