Dalaya® Dahlia Series

Green-leaf, garden dahlia features big blooms and exotic bicolors that charm with awesome retail appeal. This series is early to flower, slow to fade and is known for having excellent garden performance that beats the competition across all varieties. Plus, Dalaya is well-branched with an exceptional habit, ideal for 2.5-qt. and larger pots.
This variety features a new anemone flower form that maintains its center twill for lasting color after outer blooms shatter. Plus, bright orange, non-fading color and clean, green foliage.

Container Size
General Information
Height:12 - 16" (30 - 41cm)
Spread:12 - 14" (30 - 36cm)
Rooting Guidelines
Recommended Cell Size (in millimeters):25 mm
Rooting Hormone (IBA + NAA mix):yes
Average Days with Mist:9 to 12
Early PGR Treatment Recommended (after 7 - 10 days):Apply B-Nine 1,500 PPM (S)

PGR applications during rooting:
Sprays only. Cover the plants and avoid run-off as much as possible. For vigorous products, first application should be done about 7-10 days after sticking, second when needed. Please test before use.

Average Propagation Weeks:5
Pinch in Propagation:yes
Comments:Rooting hormone will even out rooting. Night interruption or extended day will help prevent tuber formation in short day seasons.
Rooting & Finishing
Media pH:5.8-6.2

Best results are achieved if media with the correct pH is used starting with propagation.

Fertilizer Needs:200-250 PPM N/EC 1.8-2.2

Start with low concentrations after roots show and increase with plant development to the recommended levels.

Watering:maintain even moisture and consistent fertility for best uniformity

In general avoid drying out or overwatering the substrate as this will affect plant quality and finishing time. Root system will suffer when conditions change from one extreme to the other. “Growing on the dry side“ means letting the substrate become dry (substrate color turns light brown and substrate starts to separate from the pot edge) before watering.

“Keep constantly moist“ means watering the plants just before substrate becomes dry. Water management in rooting and finishing is half the success and the best way to prevent root-bound diseases, improve performance and control plant quality.

Finishing Guidelines
Temperature Needs Day/Night: 65-68°F/55-65°F 18-26°C/13-18°C

During rooting keep soil temperature measured in the liner at 70°F/21°C until cuttings are well-rooted. After planting the liner, keep temperature up until roots have developed nicely. Afterward follow recommendations.

The use of “Cool Morning“ treatments will improve plant quality, flower and foliage color, and plant habit, and harden the plants. Lower the temperature by 8-12°F/4-6°C 2 hours before sunrise until 2-3 hours after sunrise. Start treatments after plants are rooted in, well-branched and cover the media (reach the pot edges). To avoid delayed flowering, keep the average day temperature under a close watch and if necessary, increase night temperatures. Finishing of the crop depends on the average day temperature, and positive or negative DIF methods as well as “Cool Morning” can be used to improve plant quality.

Pinch after Transplant (unpinched liners):yes
Light Levels in Foot Candles:5,000 to 7,000
Plant Growth Regulators (PGR) (S) = spray / (D) = drench:B-Nine 1,500-2,500 PPM (S), B-Nine 1,500 PPM (S)/Cycocel 750 PPM (S) tank mix, Bonzi 2-4 PPM (D)
Pests and Fungal Diseases:Thrips, Leafminers, Aphids, Botrytis
Comments: Night-break or extended day lighting during early Spring (natural short days) will help prevent tuber formation.
Crop Time
