Corina is a new small-flowered viola series with a uniform and well-branched habit. Corina can be used for different types of pack and pot sizes. The plants branch strongly and fill pots fast. They have a mounding garden habit and are covered in multiple flowers, flowering from the beginning until the end of the season.
Transplant seedlings in a well-drained media with a pH of 5.8 to 6.0. Allow media to dry slightly between waterings. Do not allow plants to wilt. Plants can be grown at 50 to 59° F or as cool as possible during warm weather conditions.
Fertilize regularly 100 to 150 ppm with a calcium-based fertilizer. An application of ammonium nitrate helps to expand the leaves. During cool weather production, ammonium-based feeds may encourage root rot problems. A high concentration of nitrogen may promote stretching.
Check/monitor for fungus gnats and shore flies during plug production and for aphids during early stages after transplant. Damping-off, black root rot, foliar leaf spots and Botrytis blight are common.from Hem Genetics
