A common misconception is that they don’t need much water or attention. “They are tough plants, but they’re surprisingly sensitive to how much water they get – too much and they’ll rot; too little and they’ll stress and drop their flowers.” During the dry season in the top end, water them every day when it’s cool in either the morning or the afternoon. Water the soil and avoid the leaves, and don’t sit your Adenium in a saucer of water because it may rot. Fertilize with a slow release fertilizer every 8 months or so and a liquid seaweed tonic every 14 days. They require Bright Light and warm Temperatures. Be aware their blooms and sap is poisonous wash your hands after touching them and if you have pets or children keep plant out of reach. In some cases when your Desert Rose foliage starts to turn yellow this usually indicates too much water. If your plant starts to develop black spots on yellowing leaves this usually indicates either a fungal disease, over watering or it needs time to adjust to a new environment.
