This FASTFACTS provides general growing guidelines for Stained Glassworks™ Coleus (Solenostemon scutellarioides).

PROPAGATION

  • Coleus are easy to root with most other spring plants.
  • No special handling is required although bottom heat will promote quicker root development.
  • Propagate using 1 cuttings per cell for best results.
  • Cuttings root in 3-4 weeks under normal conditions.

CULTURAL REQUIREMENTS

Media

  • Sterile, well-aerated mixes are best.
  • Optimum pH range is between 5.5 and 6.3.
  • Water-holding capacity is important to achieve best consumer/post-production performance.

Irrigation/Fertilization

  • Avoid excess irrigation throughout production as it will help reduce stretch and encourage strong root systems.
  • Feed with complete, balanced fertilizers at 150-200 ppm nitrogen (CLF). E.C. of 1.5-2.0 is a good target range under most conditions.
  • Provide complete minor element program.
  • Use of Osmocote® or other appropriate slow-release fertilizer products may be beneficial in supplementing a CLF program and may provide improved performance for the consumer.
  • Provide periodic clear water applications if excess soluble salts accumulate.

Temperature/Humidity

  • Establish crop at 65°F/18°C average temperatures.
  • Once established, grow at:
    - 70-85°F/21-30°C day temperatures.
    - 55-65°F/13-18 °C night temperatures.
  • Provide good air circulation at all times.
  • Maintain relative humidity between 60 - 90%, be sure to reduce levels if temperatures are lower.

Light

  • Coleus will tolerate high light intensities (4,000-6,000 foot candles/43,100-64,600 lux), but develop more intense foliage color in shadier conditions (1,500 – 3,000 foot candles/15,690 – 31,380 lux).

Pinching

  • Cuttings may be pinched soon after transplant to encourage branching. Additional pinching can be used to create full plant habit and control height.
