Water Morning Glory
Ipomoea aquatica
Ipomoea aquatica, also known as water spinach, kangkong, or water morning glory, is a semiaquatic, tropical plant with hollow, vine-like stems that can grow up to 10 meters in length. Its leaves are broadly ovate to triangular-shaped and bright green. It produces small, trumpet-shaped flowers, typically white or light purple. It is a fast-growing plant that thrives in moist or submerged soil conditions. It is considered an important vegetable crop in many parts of Asia and is often cultivated in flooded rice paddies or ponds.

Water spinach thrives in flooded conditions, often found growing naturally in rice paddies. The companion planting helps to manage weeds, improve soil fertility, and potentially enhance the biodiversity of the ecosystem.
Pontederia crassipes
common water hyacinth
Pontederia crassipes

Water hyacinth is a highly aggressive, invasive aquatic weed that can outcompete water spinach for resources like sunlight, water, and nutrients, ultimately hindering the water spinach's growth and potentially choking it out.

Aphids

Small, soft-bodied insects that suck sap from the leaves, causing stunted growth, leaf curling, and yellowing. They also excrete honeydew, which can lead to sooty mold.

Whiteflies

Tiny, white, flying insects that also suck sap from leaves, causing similar damage to aphids. They can also transmit plant viruses.

Leaf Miners

Larvae of certain moths or flies that tunnel through the leaves, creating visible, winding trails. This damage can weaken the plant and affect its aesthetic appeal.

Steps:

    • Cut healthy stems, approximately 10-15cm long, from a mature plant.
    • Remove lower leaves from the stem cutting.
    • Plant the cuttings directly into moist soil or water.
    • Ensure the cuttings are kept moist and in a warm environment.
    • New roots and shoots will emerge within a few weeks.

Neem oil

Effective natural insecticide against many common pests like aphids and whiteflies.

Compost

Enhances soil fertility, promoting healthy growth and disease resistance.
