Pitcher Plants require consistent moisture and high humidity in order to thrive. If they experience periods of dry soil or low humidity, their pitchers will die off as a way to preserve energy. Your plant is usually able to bounce back from a period of drought, but some pitcher die-off is to be expected.
To prevent brown and crispy pitchers, follow these instructions:
Keep soil consistently moist at all times. Once the top layer feels dry, it is time to water again. Water thoroughly until it comes out of the drainage, and empty excess water out of the saucer.
A great tip to help your plant thrive is to give it a good shower when watering. Take it to a sink and spray the leaves. Remember that the pitchers should always have some water in them, so it is good to get some water in them while you’re showering your plant, just make sure they are no more than 50% full of water. Other great ways to increase humidity are to use a humidifier, add a pebble tray under your plant, or mist it daily or a few times a week.
Note: Once pitchers become more than 50% brown and dried out, they are no longer effective and can be cut off.
