🌱 How to Care for Bolivian Forest Cactus to Prevent Whiteflies?

💧 How to Water

Water when the top half of the soil feels dry, approximately every 7 to 10 days during the growing season and less frequently in the fall and winter. This epiphytic cactus tolerates some drought better than excessive moisture—it is better to let the soil get a bit too dry than too wet, as standing water quickly leads to root rot. Ideally, use room-temperature rainwater or softened water.

☀️ Lighting

Provide the plant with bright, filtered, or indirect light, such as near an east- or west-facing window. Strong direct midday sun can burn the flat stems and cause them to turn yellow or spotted, but a little morning sun is well tolerated.

🪴 Ideal Soil

Plant in an airy, fast-draining soil intended for epiphytes or cacti, preferably a mix of bark chips, perlite, and coconut fiber with a small amount of regular potting soil mixed in. The soil should retain some moisture but never become waterlogged.
