Planning notes

  • Horizontal netting
  • Landscape fabric

Cut-and-come-again. A planting keeps producing new stems over a relatively long harvest period when it is picked regularly, so successive plantings are usually spaced farther apart.

  • Support netting is commonly used.
  • Landscape fabric is commonly used for spacing and weed control.
