The Q&A Archives: Leggy Dianthus Helen

Question: My three year old Dianthus "Helen" plants are looking terribly leggy, how do I go about rejuvenating them to get the best bloom for years to come?

Answer: Generally dianthus bloom stems are relatively tall and slender looking, and this one should be in the six to eight inch range. If they seem to be abnormally long or lean sideways it may be due to lack of light. These plants really need full sun, meaning all day or six hours of full sun with noon included in those hours. You could try to rejuvenate them by dividing and replanting in a sunny well drained spot, or experiment with other locations by rooting tip cuttings this spring.
