Step-by-step

  1. 1. Direct sow 1″ deep, 36″ apart. Soil should be at least 70°F before planting. Black plastic mulch laid two weeks ahead helps in cool springs.
  2. 2. Mulch and water consistently. 2" of straw or wood chip around the base. Drip line at surface. 1" per week including rain.
  3. 3. Harvest around day 95. Cure for two weeks at 80°F to sweeten and harden the rind for winter storage.
