Culture Details
 
  • General Information

    • Height:
      10 - 12" (25 - 30cm)
      Spread:
      14 - 16" (36 - 41cm)
      Exposure:
      Partial Sun
  • Rooting Guidelines

    • Recommended Cell Size (in millimeters):
      25/35 mm
      Rooting Hormone (IBA + NAA mix):
      optional
      Average Days with Mist:
      0 to 3, reduce mist as soon as possible
      Early PGR Treatment Recommended (after 7 - 10 days): (see note)
      yes

      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:
      4 to 5
      Pinch in Propagation:
      recommended; pinch to node #3 but before developing node #5
      Comments:
      Avoid overmisting/watering of young plants. To avoid dormancy, tuberous Begonia requires a minimum day length of 14 hrs. and a minimum temperature of 55°F/13°C.
  • Rooting & Finishing

    • Media pH: (see note)
      5.8-6.2

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

      Fertilizer Needs: (see note)
      200-250 PPM N/EC 1.8-2.0 - Keep N up

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

      Watering: (see note)
      grow on the dry side

      Watering:
      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)
      68-78°F/62-65°F 20-26°C/17-18°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):
      yes; pinch to node #3 but before developing node #5
      Light Levels in Foot Candles:
      5,000 to 6,000
      Plant Growth Regulators (PGR) (S) = spray / (D) = drench:
      B-Nine 2,500 PPM (S), 250-500 PPM Cycocel (S)
      Pests and Fungal Diseases:
      Aphids, Botrytis, Pythium
      Comments:
      Start late Spring when day length increases and temperatures rise. Let media dry out between watering. Avoid stretch. To avoid dormancy, tuberous Begonias require a minimum day length of 14 hrs. and a minimum temperature of 55°F/13°C.
