💡 Joe's Top Tip
Bright, indirect light helps maintain the bold variegation. Wipe the large leaves regularly to remove dust and rotate the pot every few weeks to encourage even growth.
⚠️ Common Mistake
Most people struggle with this plant by overwatering or placing it in deep shade, which can lead to yellowing leaves, slower growth, and faded variegation.
📅 When To Come Back To Us
Bring it back (or a photo) in 6–8 weeks if you want: • Repotting advice • A health check • Help maintaining strong variegation or encouraging fuller growth
🌿 Plant Fact
The common name "Dumb Cane" comes from the plant's sap, which contains calcium oxalate crystals that can temporarily irritate the mouth and throat if chewed. It's best kept away from children and pets, and gloves are recommended when pruning.
