|I planted my Dianthus Helen back in April of this year , it is now November and I have not seen it bloom any pink flowers. The only thing that I noticed was that the green foilage has grown into a oval grass-like clump? Is there something thing wrong with this picture?
|If your plants did not flower, they may be the biennial type and will flower next year. If they're the perennial type and did not flower, they may not be getting the sunshine they crave. Dianthus should be planted where they will receive at least 4-5 hours of full sun each day. They thrive in fertile, fast draining, slightly alkaline (pH 6.75) soil. Avoid over-watering because it may tend to turn the foliage yellow. Usually a weekly watering of established plants will suffice unless the weather is extremely dry. Dianthus will often reseed themselves, so don't be too hasty in removing spent plants from the ground. Perennial varieties may be propagated by tip cuttings, layering or division. Spent flowers should be removed promptly to promote continued blooming.
Plant Dianthus species 12 to 18 inches apart and at the same depth at which they were previously growing. The crown, or top of the root structure, must be level with the surface of the soil. (Never bury any part of the stems.) Unlike most other plants, Dianthus plants should not be mulched. They require good air circulation around the stems at all times and must be kept as free from foliage moisture as possible. For continued blooming feed lightly every 6 to 8 weeks with an all-purpose (10-10-10) liquid fertilizer.
