Christmas cactuses are known for dropping buds if they don't receive the proper care. To prevent this from happening, make sure your cactus is getting enough sunlight and water. It's also important to keep your cactus away from drafts or cold temperatures. Additionally, if you notice any signs of disease or pests, be sure to address them right away. With proper care, your Christmas cactus should bloom and bring joy to your home for many years to come.
