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. Dianthus blooms bloom profusely in early spring and summer, but if you clip the blossoms off as they fade, many dianthus will rebloom later in the gardening season. Hedge shears will suffice, leaving a tufty mound of greenery behind. Mulch away from your Dianthus as much as possible.

Because dianthus can re-bloom on each stem, deadheading it should be done with caution.
