If you are looking for a dahlia series with a great color range, excellent branching, big flowers and fast finishing, Fides has an answer: the Dahlinova Hypnotica series, which features radiant colors and elegant shapes.
Dahlinova Hypnotica was given its name because it hypnotizes and intrigues. It's an appropriate name for a flower that has all the qualities to dominate its surroundings. Varieties in the series will capture eyes in any garden because of their attraction and brilliance. Fides introduced the series last year with great success, as Dahlinova Hypnotica Bronze Bicolor was named the best dahlia at Penn State University's field trials.
New Radiant Colors
Five new colors in this series will be showcased at this month's California Spring Trials: Red Bicolor, Rose Bicolor, Red Coral, Lavender and Dark Night. The new varieties, along with the others in the series, have vigorous plant habits and achieve good branching. Little to no use of plant growth regulators is needed in production and flowers are generally uniform, large and in abundance through summer. The crop time for the series is seven to nine weeks and all the dahlias are heat tolerant.
Rooting & Pinching
Fides recommends planting unrooted cuttings deep - at least up to the first set of leaves - and one liner per gallon container (see Table 1 for more details). Plants should be well misted until root initials appear. The rooting temperature should be 70°F. Average rooting time is two to three weeks.
It's also recommended to pinch when plants are established, about two weeks after planting. Allow four leaves to remain after pinching for the best branching. It is, however, important to note that pinching delays flowering by five to seven days.
Watering & Feeding
Growers should thoroughly wet their growing media with each irrigation or fertigation. They should allow plants to dry slightly between irrigations. Do not over-water, and don't allow plants to wilt. If plants do wilt, leaf margin burn can occur.
Good crop growth is obtained with 200 to 250 ppm nitrogen fertigation from a complete N-P-K water soluble fertilizer. The majority of nitrogen should be in the nitrate form. Growers should avoid high ammonia or urea fertilizers, which can reduce plant quality by encouraging soft, stretched growth. The growing media EC should range between 1.5 and 3.0 mS/cm (SME).
The ideal day temperature for Dahlia Hypnotica is 65° to 70°F while the ideal night temperature is 63° to 65°F. High temperatures will delay flowering and reduce flower size. Low temperatures will limit growth and finished plant size.
Growers should use maximum light intensity with the series. They should also avoid shading from overhead crops and use supplemental lighting with 400 to 500 footcandles HID lighting for 14 hours daily in late winter and early spring.
