Water Spinach, known as kōng xīn cài in Chinese, translates to 'empty-hearted' spinach, likely referring to its round, hollow stems. Featuring slender, long, pointed leaves, this vegetable is popular in southern Chinese and Southeast Asian cuisines, where it is referred to as 'kang kung'. Water spinach is an herbaceous aquatic or semi-aquatic perennial plant found in tropical and subtropical regions. While it grows wild in aquatic environments, it can also be cultivated in well-irrigated fields. Almost all parts of the young plant tissue are edible, with the tender shoot tips and younger leaves being preferred. In Asian cuisine, water spinach is commonly stir-fried, often with fermented white bean curd, shrimp paste, or garlic.

**Sowing and Growing:**

Soak the seeds in warm water for 24 hours or regular water for 48 hours before planting. Dig holes 4 inches deep and 5 to 12 inches apart for each seed, planting them in rows if desired. Keep the soil well-watered at all times to facilitate seed germination. Water Spinach thrives in temperatures between 68-86 degrees F (20-30 degrees C). The plant requires little attention; apply nitrogen-rich fertilizer spray every two weeks. Water daily 1-2 times per day.
