Tree Whitewash, Kaolin Clay for Apple Maggot Fly, Calcium Phosphate

Drake opens from Hilo with the I Ching hexagram 56, the Wanderer, and talks current events before turning to farm questions.

On tools: he prefers a power-scythe hedge-trimmer attachment (the Stihl/Efco Combi system) over a string trimmer for chopping brush, and says weed whacker rubber parts wear out in a year or two. His backup plan is learning blacksmithing to forge scythes from old truck leaf springs.

On fruit trees: whitewash can be made with kaolin or bentonite clay mixed with IMO, or Master Cho's method of an oatmeal paste stirred with IMO-4 and rubbed on bark to help it heal. Kaolin clay also blocks apple maggot fly but cuts into photosynthesis, so Drake would rather fix the underlying calcium deficiency and spray the fruit, not the leaves.

On calcium: use calcium and calcium phosphate together when both are called for, since calcium builds structure and calcium phosphate carries reproduction signals. He'd use both together on a fruiting persimmon tree. The episode closes with archive footage of a multilingual Q&A session with Master Cho in Muju, Korea.

Questions answered

  • 25:36 What's the best tool to cut grass or brush if fuel or lawnmower parts get expensive? — Drake prefers a power-scythe hedge-trimmer attachment (the Stihl/Efco Combi system) over a string trimmer for chopping and dropping.
  • 32:00 How much sugar should you stockpile for Korean Natural Farming ferments? — Drake keeps none stored himself, but figures a listener's 300 pounds would carry several seasons of ferments.
  • 33:55 Weed whacker rubber parts die within a year or two, what's the fix? — Rebuild worn units from spare parts now, and learn blacksmithing to forge scythes from old truck leaf springs for the long run.
  • 39:29 How do you make whitewash for fruit trees? — Mix kaolin or bentonite clay with IMO, or use Master Cho's oatmeal paste stirred with IMO-4 and rubbed on bark to help it heal.
  • 42:15 Does kaolin clay on apples help with apple maggot fly? — It works but cuts into the tree's photosynthesis, so Drake would rather treat the underlying calcium deficiency and spray the fruit, not the leaves.
  • 44:18 Should calcium and calcium phosphate be used together or kept separate? — Use them together when both are called for: calcium builds structure, calcium phosphate carries the reproduction signal.
  • 45:45 Which calcium input should you use on a fruiting persimmon tree? — Use both calcium and calcium phosphate together, especially once the fruit is setting.
