CULTURE THAT WORKS
propagation
• Roots rapidly; plant from liner at 22-24 days
• Apply rooting hormone to the base of cutting
• Uses feed aggressively; start feed program around day 7
• Low vigor level; may not require any PGR application in propagation
• Important to plant from liners into finished container as soon as they are well rooted
• Failure to feed early enough will result in yellowing and hardening
early finished growth
• Very strong-branched variety must be pinched early: at day 14-16 from a liner; at day 24-26 for direct-stick
• Very low vigor; little PGR is required for growth control
• Apply light PGR when branches are 1-1.5 in. (2.5-4 cm) using Cycocel spray at 500 ppm; optional to even out the branches
growing on
• Grows steadily once the branches develop and exhibits consistent slow growth throughout the crop until color begins
• Northern Climate: PGR should be limited to only Cycocel spray at 500 ppm to even out branches
• Southern Climate: Can use Cycocel spray up to 750; B-Nine/Cycocel tank mixes should not be used on Holly Berry
• Use caution; low vigor and very responsive to PGR, especially Bonzi
late growing stages
• Very strong root system; requires continuous feed until finish; watch media EC and reduce feed levels to avoid rapid increase in media EC, this indicates the plants' need for nutrition is waning
• High EC at finish can result in root damage, reduced shelf life and possible Pythium
• A Bonzi spray application of 5 ppm can be applied at the very end of the crop, at first pollen shed, to increase the shelf life and retain the cyathia
