Christmas cacti are beautiful and festive plants that bring joy during the holiday season. However, they are susceptible to pests such as mealybugs, spider mites, and scale insects. Using chemical pesticides can harm the plant and the environment. Fortunately, there are effective DIY organic pesticides that can protect your Christmas cactus naturally and safely.
