What is already known on this subject?• It was previously demonstrated that PBZ is effective in controlling plant height and enhancing colour of a large number of floriculture crops. However, different species have their own needs as to way of application (spray or substrate drench) and appropriate dosage.What are the new findings?• The study showed that PBZ as a substrate drench reduces plant height and enhances foliage colour in potted Dianthus barbatus × chinensis, a species at present cultivated as a cut flower. Appropriate dosage ranges from 0.5 to 1 mg a.i. per pot depending on pot size, cultivar and season.What is the expected impact on horticulture?• The ornamental plant market is characterized by being eager for novelties. Therefore, the use of Dianthus barbatus × chinensis as a new flowering pot crop, which is made possible by height control, may represent an opportunity for growers.
