Ottelia, an aquatic plant genus, demands basic needs of sunlight, warm water with ample minerals, and rich, loamy soil. They need buoyancy and sunlight to photosynthesize. Insufficient light may lead to poor growth and leaf discoloration. Common challenges include susceptibility to pests like aphids and snails and diseases like powdery mildew and leaf spot. Ottelia requires warmer temperatures, making winter a difficult period. During this season, they may adopt a dormant state, necessitating gentler care.
