- Nutrition: Feed with complete fertilizers @ 150-200 ppm Nitrogen, E.C. of 1.2-2.0 is a good target. Provide clear water applications if excess soluble salts accumulate.
- Media/Potting/Planting: Rich, well drained, at a target pH of 5.5-6.3
- Atmosphere: Provide good air circulation at all times, maintain relative humidity 60-90% (if temperatures are cooler, lower humidity).
- Growth Regulation: *chemical: Uniconazole ~ controls height and diameter. *Pinching growing terminals of young plants will encourages dense, compact growth.
V. Special Considerations
- Osmocote is a well-balanced good slow release fertilizer.
- Insect: Mealybug, Aphids, White fly, Nematodes, Spider Mites
