Planning notes

  • Horizontal netting
  • Landscape fabric
  • Pinching

Medium producer. A planting stays productive across a more limited window, so closer succession timing helps keep supply steady.

  • Pinching is commonly used in this production system.
  • Support netting is commonly used.
  • Landscape fabric is commonly used for spacing and weed control.
