About Kangkong

Botanical Overview: Kangkong, scientifically known as Ipomoea aquatica, is a semi-aquatic plant that belongs to the morning glory family, Convolvulaceae. It thrives in wet or waterlogged conditions, making it an excellent choice for ponds, water gardens, or containers.

Climate Requirements: Kangkong prefers warm, tropical, and subtropical climates, making it well-suited to Eastern Australia.

Planting Schedule in Eastern Australia

  1. Spring (September – November): Spring is the perfect time to start planting Kangkong, allowing it to establish itself before the hotter months.
  2. Site Selection: Choose a location with full to partial sun that receives at least 6 hours of sunlight a day. Kangkong can also be grown in a container placed in a pond or water feature.
  3. Planting Method: Kangkong can be grown from seeds or cuttings. If using seeds, sow them in well-drained, rich soil that retains moisture. If using cuttings, choose healthy stems with roots and plant them directly in your chosen location.
  4. Spacing: Plant Kangkong cuttings or seeds about 30 cm apart to give them room to grow.
  5. Watering: Kangkong thrives in waterlogged soil. Ensure the soil remains consistently moist but not waterlogged.

Caring for Your Kangkong

  • Thinning: Thin Kangkong plants if they become overcrowded, allowing more space for air circulation and healthier growth.
  • Fertilization: Apply a balanced, water-soluble fertilizer every 2-3 weeks to promote lush growth.

Harvesting and Enjoying Kangkong

  • Kangkong is typically ready for harvesting in about 30-40 days from planting.
  • Harvest the leaves and tender stems by snipping them with scissors or pruning shears.
  • Kangkong can be consumed raw in salads, stir-fried, added to soups, or used as a filling for dumplings and spring rolls.
