2. Watering

Yellow allamanda is tolerant of wet conditions and likes a humid environment, so water it frequently during its growing season, but reduce watering in winter.

3. Soil

Yellow allamanda is not demanding about soil. Like other plants, it needs fertile soil with good drainage, which promotes its growth.

Yellow allamanda needs sufficient nutrients to grow well, so fertilise it regularly, generally once every half month.

Although yellow allamanda is toxic, it can still suffer from pests and diseases. Once pests are found, spray insecticide immediately, which is both fast and effective. If the plant is found to be infected by a virus, cut off the diseased branches, which is simple and quick, but be careful not to touch the plant's sap.
