You're in luck, because it's the perfect time to fertilize your Christmas cactus! Christmas cacti are known to be particularly sensitive to over-fertilization, so it's important to feed them with a balanced, slow-release fertilizer during the spring months. It's also a good idea to cut back on the amount of water you're giving your plant during this time, since too much moisture can lead to root rot. Be sure to give your cactus plenty of bright, indirect sunlight and keep the soil evenly moist. With proper care, your Christmas cactus will be blooming in no time!
