🌱 How to Care for Pua ʻala to Prevent Slugs and Snails?
💧 How to Water
Water when the top few centimeters of soil are dry, roughly every 2 weeks in summer and every 3 in winter. If the stem feels soft when you squeeze it, it is rotting: stop watering right away and let it dry.
☀️ Lighting
Lots of light. Outdoors, morning sun with some afternoon shade works best. Indoors, next to a very bright window. Leaf drop at the height of summer can mean too much sun.
🪴 Ideal Soil
Cactus and succulent mix with grit or perlite so water drains straight through. Use a pot with several drainage holes.
