Growth Stages
Tuber Dormancy & Preparation
Winter months (November-February)Tubers are resting and should be stored in cool, dry conditions. No visible growth yet.
Store at 65-70°F in darkness. Check periodically for rot or mold. Do not water dormant tubers.
Sprouting & Emergence
2-3 weeks after plantingSmall shoots and leaf buds appear from the tuber. First tiny leaves unfurl, pale and tender.
Plant tuber pointed-side up in warm, moist soil (75-80°F). Maintain high humidity. Provide bright, indirect light. Water gently to avoid rot.
Vegetative Growth
3-6 weeksStems lengthen and multiple leaves emerge. Leaves expand rapidly, developing characteristic white coloring with red spotting and green veining.
Maintain warm temperatures (70-80°F). Water consistently. Apply balanced liquid fertilizer every 2-3 weeks. Increase humidity. Support tall stems if needed.
Peak Foliage
Throughout summer and early fallPlant reaches mature size with numerous large, fully-colored heart-shaped leaves displaying brilliant white with red accents. Small flower spathes may appear (inconspicuous).
Continue consistent watering and fertilizing. Remove any flower spathes if foliage is the desired feature. Monitor for pests. Maintain warm, humid environment.
Dormancy Preparation
4-8 weeks (September-November)Leaves yellow and wither as temperatures drop and daylight decreases. Plant naturally enters rest period.
Gradually reduce watering as foliage declines. Stop fertilizing. Allow leaves to drop naturally. Reduce light and temperature gradually. Prepare tuber for storage.

Harvest Tips
Caladiums are grown for foliage display, not harvest. Remove individual leaves that yellow or become damaged to encourage plant appearance. In fall when foliage naturally declines, allow leaves to die back completely. Once all foliage is gone and soil is dry, carefully dig tuber, clean off soil, dry thoroughly, and store in cool (65-70°F), dry location for winter dormancy. Tubers can be divided when showing multiple growth eyes.
Fun Facts
- 🌱 Caladium White Queen tubers are planted pointed-side up, and each tuber can produce 10-20 leaves during a single growing season under optimal conditions.
- 🌱 Despite their tropical appearance, caladiums are deciduous and naturally dormant during winter, requiring a complete rest period to thrive the following year. They cannot tolerate temperatures below 60°F and should be brought indoors or stored before frost.
- 🌱 The striking red spotting and white coloring in Caladium White Queen is due to anthocyanin and carotenoid pigments; these colors intensify with bright, indirect light and can fade if light is too dim, causing the plant to revert to more green coloring.
