PERENNIAL PICK OF THE WEEK
DIANTHUS 'FIREWITCH

This week, we are highlighting 'Firewitch', the 2006 Perennial Plant Association Plant of the Year. 'Firewitch' has been problem-free. It has required few inputs to produce a great crop. Very little fertilizer and water is required, which resulted in strong, hardened-off plants that are compact, healthy, and more readily resistant to pathogens. 'Firewitch' thrived in our greenhouses during a very warm and dry summer under light shade (about 30%).
Quick Growing Tips: Dianthus thrives when grown consistently somewhat dry or watered sufficiently and then allowed to dry down thoroughly. We provide the plants with just enough water to sustain good growth, but do not keep the soil too wet at any point. Soil that stays wet for too long will significantly slow down the root growth of 'Firewitch'.
FertilizingTo keep the foliage from stretching, which requires more trimming than desired, we fertilize our Dianthus very little. While we grow them lean, occasional applications of liquid feed may be applied to encourage the foliage to bulk up a little quicker.
Pests and Diseases'Firewitch' is a strong grower that is generally not as prone to disease as some Dianthus cultivars. This characteristic, combined with judicious water and fertilizer management, will keep the crop healthy. You can be confident in purchasing 'Firewitch' from Greenscape Gardens.
