Description
Ipomoea aquatica, commonly known as water spinach, kangkong, or water morning glory, is a semi-aquatic, fast-growing perennial plant in the morning glory family. It is widely cultivated throughout tropical and subtropical Asia for its tender shoots and leaves, which are a popular leafy vegetable. The plant has long, hollow, buoyant stems that can grow in water or on moist soil, rooting at the nodes. Its leaves are variable in shape, ranging from arrowhead-shaped to lanceolate. The flowers are trumpet-shaped and can be white, pink, or pale lilac.
Due to its rapid growth and ability to form dense, tangled mats, Ipomoea aquatica is considered an invasive weed in some parts of the world, where it can obstruct waterways and outcompete native aquatic vegetation.
Germination Guide
General Instructions (English)
If you don’t have a seed spreader, greenhouse, or similar equipment, follow these steps:
Fill a container with good drainage using a mix of peat and perlite.
Moisten the substrate, ensuring it’s damp but not soaked.
Plant the seeds and cover them lightly with the substrate.
Place the container or pot inside a polyethylene bag (a ziplock bag works well and is available at supermarkets).
This method will provide the ideal temperature and humidity for the germination phase.
Keep the seeds in a bright location, but avoid direct sunlight.
Open the bag every 2–3 days to check the moisture level and see if any seeds have germinated. This also allows for air exchange, preventing unwanted fungi.
After germination, carefully transfer the seedlings to individual pots, taking care not to damage the delicate roots.
Acclimatize the seedlings for 4–12 weeks before transplanting them to their final location.
Transplant only on cloudy days to reduce stress on the seedlings.
Prepare the planting pit 2–4 weeks in advance by adding the necessary fertilizers for optimal growth.
