How to Prune Heart of jesus?

Pruning Time: Spring, Summer

Be cautious not to remove too many healthy leaves at once. Caladium bicolor relies on its leaves for energy through photosynthesis. Removing too many can stress the plant and hinder its growth. Caladium bicolor exudes a thin sap that can be irritating to some people. Wearing gloves is advisable during pruning to avoid skin irritation. Before and after pruning, always sanitize your tools. A simple solution of half bleach and half water works well to kill any bacteria or fungal spores that might be lingering.

How to Propagate Heart of jesus plant?

Propagate Time: Spring,Summer

Identify healthy tubers with visible growth buds. Tubers should be plump and free from signs of rot or disease, ensuring they have the vitality needed to establish new plants.

Using a sterilized knife, carefully cut the tubers ensuring each section has at least one bud. Precision during this step reduces the risk of harming the tuber, enhancing the chance of successful propagation.

Place the cut sections into well-draining soil. Ensure buds are facing upwards and cover with soil lightly. Proper planting depth and orientation are crucial for optimal growth and health of the new plants.

How to Repot Heart of jesus plant?

Repotting frequency: Every 1-2 years

Caladium bicolor should be repotted when you notice roots protruding from the drainage holes, or the plant's growth appears stunted, usually indicating it's root-bound. Another signal is when the leaves start to droop despite good watering and lighting conditions, suggesting the soil is compacted or depleted of nutrients. Ideally, aim for repotting during the growing seasons of spring or summer for optimal recovery and growth.

Select a pot that is 1-2 inches larger in diameter than the current one to accommodate root growth. Ensure the pot has adequate drainage holes, which prevents waterlogged soil and root rot. A pot made of a breathable material like terracotta is preferable as it promotes airflow to the roots, maintaining a healthy root environment essential for vibrant foliage.

Choose a well-draining potting mix that retains some moisture but allows excess water to escape freely. A mix containing peat or coco coir, combined with perlite or sand, is ideal. This combination fosters an aerated soil environment that supports healthy root development and nutrient uptake, key factors for the plant's lush growth and vibrant leaf coloration.
