Sometimes, you might notice that even if you water it frequently enough, it will start to dry out. When you see that the flowers are beginning to wilt and there's not enough water, the issue might be in the container where they are planted. Choose a bigger one if this is the case. Buy a pot that drains easily. You will need to mix it with the right potting soil and clean sand so it will absorb more water easier.
The soil that is too wet will not go well with the roots. Since this species is an epiphyte, it won't be able to handle soggy roots since it absorbs water and nutrients from the air. It's best to ensure that there's proper drainage to prevent fungal infections.
When you notice the cactus is limp, you can transfer or re-pot it into fresh earth. Gently remove the soil as much as possible and keep it evenly moist. Mist the cactus frequently whenever possible.
After the flowers have finished blooming, you might want to cut back on watering until you see new buds appearing. When the soil dries too much, the buds will begin to drop, so you might want to add some water but not too much.
Sometimes, underwatering, which is followed by overwatering that many owners do for compensation, is quite common. These cacti are considered to be succulents. The lack of water is not noticeable until everything is too late. They show that there are issues when they begin to droop and wither. The well-intentioned plant owner will give them massive amounts of water.
This is where the roots become desiccated. They become so dry that they can't take in any excess water. It will result in waterlogged plants, and the remaining roots may rot. If you notice some signs of wilting or underwatering, you can try to bring the species back to life with regular and frequent watering. However, make sure that it won't be a deluge, so you'll give the cactus a chance to regenerate and recover its roots.
