How long do Caladium bulbs take to sprout?

Caladium bulbs usually sprout within 2–4 weeks, depending on temperature and moisture. Cooler conditions may delay sprouting.

Why hasn’t my Caladium bulb sprouted yet?

This is usually due to cool temperatures, overwatering, or low-quality soil. Keep the soil slightly moist (not wet) and place the pot in a warm, bright area.

How often should I water Caladium bulbs?

Water lightly after planting. Once leaves appear, water when the top soil feels dry. Avoid waterlogging, as bulbs can rot easily.
