2

Vegetative Growth

2-3 months

New leaves emerging regularly; plant developing its characteristic large, lobed foliage with prominent veining.

Maintain consistent moisture and high humidity. Begin monthly fertilizing with balanced, diluted fertilizer during growing season (spring/summer).

Mature Foliage

Ongoing in proper conditions

Plant producing large, fully-formed leaves with rich blue-green coloring and white veining. Potential small inflorescences may develop.

Maintain optimal conditions. Rotate plant monthly for even growth. Wipe leaves gently to remove dust. Watch for pest issues.

4

Seasonal Dormancy
