Why Do Heart of jesus Plants Need Overwintering?

The Heart of jesus, known for its striking, heart-shaped leaves that come in an array of colors, is a tender plant. This means it's susceptible to frost and cannot survive the cold winter months, especially in regions where the temperature drops significantly. Overwintering is essential to preserve these beautiful plants for the next growing season. By digging up and storing the tubers, you ensure that the plant can be replanted and thrive once the warmer weather returns.

Step-by-Step Guide to Overwinter Heart of jesus Plants

Digging Up the Tubers

Begin by carefully digging around the base of the plant, taking care not to damage the tubers. Use a garden fork or spade to gently lift the tubers from the soil. Shake off any excess soil, but do not wash them as excess moisture can lead to rot during storage.

Cleaning and Drying the Tubers

After lifting the tubers, remove any remaining soil by brushing them gently. Next, allow the tubers to dry in a cool, shaded area for about a week. This drying process is crucial as it helps to harden the tubers and prevents mold or rot from developing during storage.

Storing the Tubers Properly

Once the tubers are dried, place them in a layer of dry peat moss, vermiculite, or sawdust within a cardboard box or paper bag. Store them in a cool, dark place where the temperature remains between 10°C to 15°C (50°F to 59°F). Ensure that the storage area is well ventilated to prevent moisture buildup and rot.

How to Care for Heart of jesus During Winter

Providing Adequate Light

If you're keeping your Heart of jesus as an indoor plant during winter, make sure it receives sufficient light. Place the plant near a bright, indirect light source, such as a north or east-facing window. Avoid direct sunlight as it can scorch the delicate leaves.

Maintaining Ideal Temperature and Humidity

Keep indoor temperatures around 18°C to 24°C (65°F to 75°F). Heart of jesus prefers a humid environment, so consider placing a humidifier nearby or set the plant on a tray with water and pebbles to maintain humidity. Be cautious about placing the plant near heating vents or drafts, as this can dry out the air.

Watering and Fertilizing Tips

During winter, water your Heart of jesus sparingly. Allow the top inch (2.5 cm) of soil to dry out between waterings. Over-watering can lead to root rot, which is a common issue in the winter months. You can reduce fertilization during the winter months but resume a balanced, slow-release fertilizer in early spring when you plan to replant the tubers.
