Caladiums are vibrant, tropical plants that add a splash of color to gardens and indoor spaces. Proper ongoing care ensures they thrive year after year. This monthly maintenance checklist helps gardeners keep their caladiums healthy and beautiful throughout the growing season.
Monthly Maintenance Overview
Caladiums require consistent attention to maintain their lush foliage and vibrant colors. Each month, specific tasks should be performed to promote healthy growth, prevent pests, and prepare the plants for seasonal changes.
January
In colder months, especially in temperate regions, indoor care is essential. Keep the bulbs in a cool, dark place if they are dormant. Check for any signs of rot or disease and remove damaged foliage.
February
Begin planning for the upcoming growing season. If you store bulbs indoors, inspect them for mold or shriveling. Start indoor propagation if desired, using well-draining soil and bright, indirect light.
March
As temperatures rise, start preparing outdoor beds. Gradually acclimate caladiums by exposing them to outdoor conditions for a few hours each day. Fertilize lightly to encourage healthy growth.
April
Plant new caladium bulbs outdoors after the danger of frost has passed. Water regularly, keeping the soil moist but not waterlogged. Apply a balanced fertilizer to support foliage development.
May
Maintain consistent watering and mulch around the plants to retain soil moisture. Watch for pests such as spider mites or aphids, and treat infestations promptly.
June
Caladiums reach full growth during summer. Continue watering deeply and regularly. Deadhead any yellowing leaves to promote new growth and prevent disease.
July
Apply a liquid fertilizer every 4-6 weeks to support vibrant foliage. Keep an eye out for pests and treat as needed. Ensure plants are not stressed by drought or overwatering.
August
As the growing season peaks, continue regular watering and fertilizing. Consider dividing crowded clumps to encourage healthy growth and propagation.
September
Begin reducing watering as days grow cooler. Remove any dead or yellowing leaves to prevent disease. Prepare to dig up bulbs if frost is imminent.
October
In regions with frost, carefully dig up caladium bulbs before the first freeze. Clean and store them in a cool, dry place for winter dormancy.
November
Continue storing bulbs in a dark, dry environment. Check periodically for signs of mold or shriveling, and discard any damaged bulbs.
December
This is the ideal time to plan for next year’s caladium garden. Review what worked well and prepare supplies for planting season. Keep bulbs in optimal storage conditions until spring.
