Growing instructions for Caladiums
For outdoor planting, bulbs should be planted when night temperatures are 65 F or above and the soil is warm to the touch. #1 size bulbs should be planted 2 inches deep and about 6-8 inches apart. Jumbo size bulbs should be planted 2 inches deep and spaced every 10-12 inches apart. Ideal conditions are partial sun and partial shade. They will grow in full sun, however they may require more water. The soil should be light and well drained. Leaf mold or peat moss may be added for better results. These plants require little water at first to prevent deterioration, then water freely when leaves appear.
As a house plant use 3 #1 size bulbs to a 6 inch pot. Plant bulbs 2 inches below the surface using light garden soil. Water sparingly until first leaves appear. They may be transplanted after flowering.
They may also be used as fresh cut flowers. We recommend cutting the leaves at least 3 to 6 hours prior to using them. Cut them off near the bottom of the stem and immediately set stems in water. They will go through a wilt stage in the first 24 hours, however they will perk up. They should last in an arrangement for 2 to 3 weeks.
To store your bulbs from year to year we suggest digging them after your first cool spell. Allow them to cure for 7 to 10 days before storing. Store them in something ventilated such as old pantyhose or an onion sack. Keep them ABOVE 65 F until time for planting again.
