When to Plant Caladium Bulbs?

Caladium bulbs, also known as tubers, are the underground storage organs of the plant. They store energy and nutrients for the plant to grow and produce new leaves. Caladium bulbs are usually sold in late winter or early spring, and they should be planted after the last frost date in your area.

The best time to plant caladium bulbs is when the soil temperature is at least 65°F (18°C). To check the soil temperature, please use a thermometer or your finger. Insert the thermometer or your finger about 2 inches deep into the soil. If it feels warm, you can plant your caladium bulbs. If it feels cold, you should wait until it warms up.

How to Plant Caladium Bulbs?

Planting caladium bulbs is easy and fun.

  1. Choose a location for your caladium. Caladium can grow in both sun and shade, but it prefers partial sun to full shade.
  2. Dig a hole about 2 inches deep and wide enough to accommodate the bulb.
  3. Caladium bulbs have a flat side and a rounded side. The flat side is the bottom, and it has small buds or eyes that will sprout new leaves. The rounded side is the top, and it has a depression or indentation that marks the center of the bulb.
  4. Place the bulb in the hole. Make sure the flat side is facing down and the rounded side is facing up. The top of the bulb should be about 1 inch below the soil surface.
  5. Gently fill the hole with soil and pat it down lightly. Water the bulb thoroughly to settle the soil and remove any air pockets. Keep the soil moist but not soggy until the bulb sprouts.
  6. Space the bulbs about 8 to 12 inches apart, depending on the size and variety of the caladium.

How to Care for Caladium?

Caladium is a low-maintenance plant that does not require much attention. However, there are some things you can do to keep your caladium healthy and happy.

  • Water: Water your caladium when the top 25% of the soil is dry. Water thoroughly, and be sure to empty the saucer of any excess water to prevent root rot. When the plant goes dormant in the winter, water very sparingly to allow the plant to rest. Begin watering again in the spring to “wake” the plant out of dormancy.
  • Sunlight: Your caladium will thrive best in bright to medium-bright indirect light. It can tolerate direct morning sun like in an eastern or northern window. Avoid areas in which it will be exposed to harsh afternoon sun.
  • Fertilizer: For best results, use a liquid houseplant fertilizer diluted to half the recommended strength once a month during the spring and summer. Never apply fertilizer to dry soil, always make sure the soil is damp before feeding your plant. No fertilizer is needed in the fall and winter months.
  • Soil: Your caladium prefers rich, well-drained, and slightly acidic soil with a pH of 5.5 to 6.2. You can use a peat-based potting mix or add some peat moss or perlite to your regular potting mix to improve drainage and acidity.
  • Prune: Prune off the old discoloring leaves as they appear. This will keep your plant looking neat and healthy, and encourage new growth.
  • Temperature & Humidity: Prefers temperatures between 65-80°F. Avoid cold drafts and sudden temperature changes. Over winter, when the plant is naturally dormant, keep it in an area that stays above 60°F. In spring, very warm temperatures at 75°F or above are helpful to “wake up” your caladium more quickly. Your caladium also prefers a humid environment. Mist the leaves regularly, place a humidifier nearby, or use a pebble tray to raise the humidity.
  • Container: Choose a container that has drainage holes and is slightly larger than the tuber. The best time to repot is in the spring when the plant is starting to grow again.

Caladium can be propagated by dividing the bulbs or by growing them from seeds. However, dividing the bulbs is easier and faster than growing them from seeds.

How to propagate caladium by dividing the bulbs?

  1. Dig up the bulbs in late fall or early winter, before the first frost. Use a garden fork or a shovel to gently lift the bulbs out of the ground, taking care not to damage them. Shake off any excess soil and rinse them with water.
  2. Cut the bulbs into smaller pieces, making sure each piece has at least one eye or bud. You can use a sharp knife or a pair of scissors to cut the bulbs. Discard any rotten or diseased bulbs or pieces.
  3. Cure the bulbs for a few days in a warm and dry place, such as a garage, a shed, or a basement. This will help the cut surfaces heal and prevent fungal infections.
  4. Store the bulbs in a cool and dark place, such as a refrigerator, a closet, or a drawer. You can place the bulbs in a paper bag, a cardboard box, or a mesh bag, and label them with the variety name and the date. Do not store the bulbs in a plastic bag, as it may trap moisture and cause rotting.
  5. Plant the bulbs in spring, following the same steps as described above.
