A premium pomelo variety from Thailand, prized for its unique contrast between the emerald rind and deep red interior.

📅 Precise Ripening Months

Pomelos have a long maturation cycle in Southern California, typically taking 8–10 months from flower to harvest:

  • Peak Quality Month: December and January (This is when the flavor profile is most balanced and the sugars are at their peak).

🛠️ Care & Management

  • Aphid Control (March–May): Use Neem Oil or horticultural soap on new spring flushes. Controlling ants in the garden is crucial, as they protect aphids from natural predators.
  • Nutrient Strategy: Apply phosphorus and potassium-rich fertilizers in late February to support blooming and fruit retention.
  • Irrigation: Maintain steady soil moisture during the summer to prevent fruit drop or rind splitting.
