When to Plant Caladiums

Caladiums need warm soil to start growing. Planting too early in cool conditions can cause tubers to rot.

  • 🌡 Outdoors: Wait until the soil temperature reaches 70°F and frost danger has passed.
  • 🌱 Cooler climates (Zones 7 and colder): Start indoors 4-6 weeks before the last frost and transplant when nights stay above 60°F.
  • 🏡 Indoors: Can be planted anytime as long as they receive proper warmth and light.

Choosing the Right Growing Location

Caladiums prefer shade but can tolerate some sun.

  • 🌤 Best in filtered sunlight or light afternoon shade.
  • ☀️ Some sun-tolerant varieties handle full sun with extra watering.
  • 🌳 Shade varieties do well in dappled light or morning sun with afternoon shade.

Pro Tip: The more sun exposure, the more water Caladiums will need.

Soil Preparation & Planting

  • 🌱 Use well-draining, nutrient-rich soil. Compost or peat moss can improve moisture retention.
  • 🌿 Plant tubers 1-2 inches deep, knobby side up.
  • 📏 Space them 8-12 inches apart to allow full foliage spread.

Container Growing: Use high-quality potting mix and a pot with drainage holes—Caladiums dislike soggy soil.

Watering & Humidity Needs

  • 💦 Keep soil consistently moist but not waterlogged.
  • ☀️ Full-sun Caladiums need more frequent watering.
  • 🌿 Boost humidity by grouping plants, using pebble trays, or misting.

Watch out for: Overwatering (causes rot) and underwatering (causes wilting).

Fertilizing for Healthy Growth

  • 🌾 Apply a diluted, balanced liquid fertilizer every 2-3 weeks.
  • 🌱 Slow-release fertilizers provide continuous feeding.
  • 🚫 Avoid high-nitrogen fertilizers, which can make leaves overly green and dull colors.

Protecting Caladiums from Pests & Damage

  • 🌀 Wind: Shelter plants from strong winds to prevent torn leaves.
  • 🐜 Pests: Watch for aphids, mealybugs, spider mites, and thrips—treat early with insecticidal soap.
  • 🛡 Fungal rot: Avoid soggy conditions by ensuring good drainage.
  • 🐰 Wildlife: Deer and rabbits may nibble on Caladiums, so plant near resistant varieties if needed.

Ongoing Care & Maintenance

  • 🍂 Remove old leaves to encourage fresh growth.
  • 🌱 Mulch around plants to retain moisture and suppress weeds.
  • 🌿 Group plants together for increased humidity.

Caladiums as Annuals vs. Perennials

Caladiums are usually grown as annuals, but in warmer regions, they can be overwintered as perennials.

  • 🔥 Zones 9-11: Can stay in the ground year-round.
  • ❄️ Zones 8 and colder: Dig up tubers in fall and store them indoors.

Overwintering Caladium Tubers

  • 🍂 In fall, reduce watering as leaves die back.
  • 🧹 Dig up tubers, shake off soil, and let them dry for a few days.
  • 🏡 Store in peat moss or dry soil in a cool, ventilated space (50-60°F).
  • 🌱 Replant in spring once the soil warms above 70°F.

Can Caladiums grow indoors year-round? Yes! Keep them in bright, indirect light and reduce watering in winter.

Caladiums in Containers
