Media and pH Requirements: A well-drained soil is required at a pH of 5.5 to 6.2. Water thoroughly and let soil dry between irrigations. Over watering, oxygen deprivation and poor drained soils may cause foliar chlorosis similar to Iron or Manganese deficiency. A pH above 6.5 may cause Iron (Fe) deficiencies.
Fertilizer Requirements: Well-balanced feed at 200 to 250 PPM Nitrogen on constant basis. Additional Iron (Fe) and/or Manganese (Mn) may need to be added to stock feed for maximum growth.
Pinching Requirements: Suggested pinch after plant is established. The liner arriving should have been pinched and/or well branched arriving to customer.
Plant Growth Regulators: This plant will grow quickly and to great lengths.
