Senetti® Blue Bicolor 20

(Flowering Only License)

Senetti® Cineraria hybrida
The low-maintenance Senetti series is a great addition to early-Spring assortments, thriving in cool temperatures. This durable pericallis will hold up at retail and offers fast sell-through. Plus, it fills a larger pot size than many other early-Spring crops. Heads will turn at retail with masses of vivid blooms above rounded, compact foliage. Senetti offers superior garden performance, with strong stems, excellent vigor and the ability to withstand a range of weather conditions. 
Blue bloom with a white halo around a dark center.

Culture Details
  • General Information

    • Height:
      12 - 24" (30 - 61cm)
      12 - 18" (30 - 46cm)
      Partial Sun, Sun
      Hardiness Zone:
      9a - 11
  • Rooting Guidelines

    • Recommended Cell Size (in millimeters):
      25 mm
      Rooting Hormone (IBA + NAA mix):
      Average Days with Mist:
      Early PGR Treatment Recommended (after 7 - 10 days): (see note)

      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:
      Pinch in Propagation:
      Keep humidity high to ensure cuttings are kept moist. After 14 days of misting, cut misting time in half. Shade may be required to protect leaves. Use fertilizer once roots develop.
  • Rooting & Finishing

    • Media pH: (see note)

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

      Fertilizer Needs: (see note)
      medium 260 PPM

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

      Watering: (see note)

      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: (see note)
      55-75°F/55-75°F 13-24°C/13-24°C

      Temperature needs day/night:
      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):
      Light Levels in Foot Candles:
      5,000 to 6,000
      Plant Growth Regulators (PGR) (S) = spray / (D) = drench:
      B-Nine 2,000 PPM (S) every 14 days.
      Pests and Fungal Diseases:
      Aphids, Mites, White Fly, Thrips, Powdery Mildew, Thielaviopsis
      Avoid overwatering, avoid frost; shade in last three weeks of finishing may cause stretch.
