Perennials are best planted in the spring or fall when the weather is cooler. Plant nursery starts outside in the spring for biennials and annuals, or sow seed indoors 6 to 8 weeks before your last frost date for bloom the same year. The following year, seeds placed directly in the garden in late spring or summer will bloom.
How to plant:
Depending on the kind, space plants 6 to 12 inches apart. Mix in 2 to 4 inches of compost after loosening the soil to a depth of 12 inches. Place the plant in a hole twice the diameter of the root ball, with the top of the root ball level with the soil. Water well after gently tamping soil around the plant’s base.
Do dianthus plants come back every year?
These plants are perennials with a short life span, although they are commonly planted as annuals in Missouri and other colder climates. Annuals have a single growing season. Many Dianthus types, on the other hand, self-seed every year. That is to say, they re-grow each spring.
How late can I plant dianthus?
When planting dianthus, wait until the threat of frost has gone and plant them at the same level as they were in the pots, with 12 to 18 inches (30-46 cm) between the plants.
How do you plant dianthus in the ground?
Dianthus can be cultivated from stem cuttings, seeds started indoors, or simply sown into the soil.
Start seedlings inside 2-8 weeks before the last frost date in your location. Sprinkle seeds over the top of a light, loamy soil mix before covering with a little layer of dirt.
To keep the soil moist and warm, cover the container with a cloche or plastic bag. Move seedlings into their individual pots after they have 2-3 genuine leaves. Once they reach a height of 4-5 inches, transplant them outside.
Once all threat of frost has gone, straight sow seeds outdoors to a depth of 1/8 inch. Keep the soil moist, and thin to 8-12 inches apart after they have 2-3 leaves.
Cut several non-flowering stems from the parent plant right below a leaf joint to start stem cuttings.
Trim the lower leaves from the stem, leaving 4-5 sets of leaves at the top. Dip the base in hormone rooting powder and plant it up around the perimeter of a light potting soil container.
Fill a plastic bag halfway with water and secure the top with a twist tie. Set in a shady position in the garden that gets early sun but is protected from the scorching afternoon sun.
In around 4-5 weeks, stem cuttings should root. Remove the dirt ball from the cuttings and gently separate them, then pot them up into individual containers.
Overwinter in a warm, sheltered area away from frost and freezing weather. Once the soil has warmed up, plant out in the spring.
Will dianthus survive winter?
Annual dianthus tolerates minor frost well, but strong freezes can be damaging. Dianthus can be grown as a winter annual in milder climates.

Will dianthus bloom all summer?
Drought-tolerant dianthus plants are ideal for sunny places near the edge of a flower border or a sidewalk. The plants freely take up residence in the fissures of a rock wall, where their roots can remain cold. Pinks stretch out in small flower pots to form a lovely spectacle. They thrive in the cool spring and fall conditions, but they are remarkably flexible. They endure heat and thrive in areas with excessive rainfall and humidity as long as they are planted in well-drained soil.

Hedge shears will suffice, leaving a tufty mound of greenery behind. Mulch away from your Dianthus as much as possible.
