Preparation • disinfect propagation area and equipment (tubs and boxes) • rooting in trays: use new or disinfected trays • floor or table heating is necessary Growing medium sterile propagation substrate pH 5,8-6,2 or Jiffy or Oasis • without additional fertilizers • assure open substrate • during sticking the substrate should have propagation temperature • substrate must be moist, not wet Pots If direct sticking in pots, use new pots only Processing as fast as possible - every minute is important should the cuttings not be stuck immediately upon delivery • open the box and store the cuttings at 46°F • stick them to the first crown • water so that the growing media has contact to the base • first Zonal, then Ivies Temperatures
Shading • day 1-14 from 18.000 Lux • day 15-21 from 20-25.000 Lux Assimilation light Light can be applied, with Son T 400 W (1 lamp 10 m2) when the cutting is turgid (3rd day) Water for rooting 1. Spray mist: • use spray mist instead of watering! • only when foliage is dry • if the heating is strong, also spray at night • one day after potting the cutting has to stand firm • cuttings that dehydrate, yellow and losses have to be expected. • mist should be turned off after about 10 days 2. Rooting without spray mist is possible under fleece tents (use new material only): • remove fleece tent immediately after production of the callus (10th day) • with plastic cover, after the 4th day ventilation at night is necessary.  Avoid direct covering with fleece or plastic because it causes water drops; the risk of Botrytis is then very high.
Use of growth retardants • Ivies and Zonals - according to needs - after 3 weeks first treatment with CCC 0,15%. Depending on cutting quality and variety characteristics, a second treatment may be necessary. Plant protection against Botrytis and Pythium • cultivate with ventilation • after 10 to 14 days' treat against Botrytis • to be repeated possibly after one week • Preventive application against Pythium as a drench with fan-shaped jets so that both substrate and stems are covered.
