Kang Kong (Water Spinach or Ong Choy) Bamboo Leaf seeds

Ipomoea aquatica
Packet - 15 seeds, 5g

Kang Kong Bamboo Leaf or Water Spinach is a Filipino staple (Ching Quat) when it comes to vegetables. Rich in vitamins and minerals and is abundant in the country. It is an aquatic tropical vine that can be successfully grown in moist soil. This variety produces green leaves and green stems.

Commonly called Water Spinach, Kong xin cai, Kangkong or Ong Choy, Ipomoea aquatic goes by many names around the world. It has spinach-like leaves with long hollow stems. Almost all parts of the young plant are edible, but the tender shoot tips and younger leaves are preferred.

The spinach-like leaves are mild and tender and without any trace of the oxalic acid taste of regular spinach and the long hollow stalks have the advantage of holding onto all flavourings they are cooked with and stay crunchy even when wilted. No wonder it is one of the most popular greens in southeast Asia.

Sowing Guide

Direct seed or transplants may be used. In warmer locations, it can be grown as a perennial. In cool to cold locations, it can be grown as an annual or as a greenhouse plant. It does very well in hydroponic systems and is an excellent permaculture plant.

It grows so fast and easily and tastes so good, that anyone in a temperate climate could grow this plant indoors in winter and outside in summer.

Water Spinach does not do well where average temperatures drop below 10oC, and do much better when the temperature is between 20 to 30oC. It tolerates very high rainfall, but not frost.

Soak seeds for 24 hours before sowing to encourage germination. Seeds can be sown directly or seedlings transplanted into the beds. The soil temperature requirement for germination is 20oC.

To produce strong seedlings, the seed should be sown 5mm deep in trays with potting mix deep enough to allow the plants to develop a good root system. Transplant when plants are 10 to 15cm tall with four true leaves.

Plant stems are not strong, but plants grown in beds support each other and produce longer stems with less branching. The highest yields are obtained by spacing plants at 15 x 15cm. They can also be grown in rows about 30cm apart

Water spinach needs much more water than most other vegetable crops. This increased irrigation can leach out readily available nutrients, so it is recommended to use slow-release forms of fertility. Where rainfall is low, frequent heavy irrigations are necessary for high-quality shoots.

The plants grow to around 30cm tall with trailing stems that can grow to 2 to 3 meters (6 to 10ft) long.

If you live in warmer locations, you may need to contain the plants or harvest often to keep it from spreading too much. It has long, jointed and hollow stems, which allow the vines to float on water or creep across the muddy ground. Adventitious roots are formed at nodes that are in contact with water or moist soil. Harvesting for human consumption is the best method, by far.

Harvest 30 to 60 days after sowing, depending on climate and culture.

Water Spinach can be harvested completely or in a cut-and-come-again manner. Plants are harvested by cutting the stem close to the ground. Shoots regrow readily and growers should get two to three cuttings of water spinach before frost.

Water Spinach is always best when used very fresh. It is very perishable and deteriorates rapidly once picked, and only stores in the refrigerator for about a day or two. It can be used as fodder for animals, including pigs, chicken and ducks.

Our Seed Guarantee

We sell only the highest quality seed that has been carefully grown, selected, picked and packed for you. We guarantee that the seeds will germinate for six months from the purchase date, if you store them as indicated on this page further down and follow the individual seed packets growing instructions.

If you have problems with seed germination not due to the weather, gardening abilities or animals, we will gladly work with you to determine the cause and send replacement seeds if necessary. If the underlying problems affecting the seeds germination are not corrected, you won't have any better results with new seed than the first time! Specific planting information is needed to help us diagnose and help correct the reasons for poor germination. Typically when there are challenges in germination, there are a few main reasons – temperature, soil moisture levels and timing. 

Please give us specific information about your germination problems; we are here to help! The more detailed information you can provide (planting time, depth, soil moisture, soil temperature, weather conditions, etc.), the better we can help you.

Phytosanitary Certificates

Some countries may require a Phytosanitary Certificate when you import the seeds.

We do not provide a phytosanitary certificates. The cost of obtaining a phytosanitary certificate is prohibitive and start at around $1,500. They also take around 5-6 weeks to arrange. Please contact your local authority to confirm the requirements for importing the seed of the species you require. Any seeds shipped to a foreign country are shipped at the buyer's risk, as we cannot assume losses from seeds that are stopped and/or destroyed at the customs offices of these countries. 

SAFE SEED STORAGE

One of the factors that most influences the germination rate of seeds is how they are stored. Like the plants that produce them, seeds come in all sorts of forms and sizes. They are also variable in their longevity. Since seed packets often contain more seeds than might be needed in one season, it’s important for gardeners to learn how to store seeds.

Vegetable seeds that are considered “long-lived” include the Brassicas (broccoli, Brussels sprouts, cauliflower, cabbage, collards, kohlrabi…) the chicory group (endive, escarole, radicchio), cucumber, kale, lettuce, melons, mustards, chillies, radish, rutabaga, sunflower, tomato and turnips. Stored correctly, these seeds should maintain a good viability for more than five years.

“Medium-lived” varieties include beans, carrots, celery, chard, eggplant, parsley, peas, pumpkin, salsify, and squash. These varieties, if properly stored, should last up to five years.

“Short-lived” seeds include corn, leek, onion, parsnip, and spinach. These are generally not recommended for more than one season, although they may maintain acceptable germination rates in the second year.

Pelleted seeds should be bought fresh each year.

Some tricks to keeping seeds and getting the best germination:

The secret to successful seed storage is “cool and dry.” As soon as your seeds arrive, store them immediately in an airtight container in a cool spot, away from any obvious heat source, and out of the sunlight. Try and store them at 4 – 10°C. Some people like to include desiccant packets with their seeds to ensure a dry environment. One other trick is to wrap a teaspoon of milk powder in a piece of tissue, and use this the same way. This will absorb any available moisture in the airtight container.

Only ever use sterilised starting mix when starting seeds indoors. Regular soil is teeming with microbes, including certain fungi that can cause damping off of seedlings, and bacteria that can harm the seeds themselves.

Once the seeds are planted, keep the temperature constant. Aim for continuous temperatures of 20 – 24°C both day and night.

Once the seeds are planted, never let them dry out. Seeds absorb oxygen as they germinate, so too much water can deprive them of this vital gas. Aim to keep the soil evenly moist. Seed starting soil is designed to provide both water retention and drainage.

Ventilate seedlings. One mistake that is easy to make is to leave the plastic dome over seedling trays on a hot, sunny day. If there is significant condensation on the plastic dome, remove it or prop it open to allow air to get in and out. On a sunny day, seedling tray domes can actually steam your seedlings.

Finally, harden seedlings off before transplanting them outdoors. Sudden plunges into cold, damp conditions can cause enough stress on young plants to cause severe stunting or death. Make the transition gradual. Using a cold frame or cloche works well.
