Kai Garden Trials

Experiment: “Weeks from planting to harvest over winter/spring”

Experiment:

  • See the difference in time to harvest (photoperiod response)
  • Even though temperatures on Waiheke are mild in winter, plant growth is also affected by day length
  • Research has shown that most plants stop active growth when day length is below 10 hours, this occurs in Auckland from the 22 May to the 22 July

 

Materials and Methods:

  • Vegetable - Cabbage Globe
  • Soil - Sheet layering compost with various organic materials
  • Blood and bone fertiliser

 

Plantings

  1. End of May (10hr light)
  2. End of June (9.5hr light)

 

Parameters to measure:

  • Observe visual growth by counting leaves and measuring diameter
