Growing Calandiva
Ideal Growing Conditions
To cultivate a healthy Calandiva, consider the following conditions:
- Light: Prefers bright, indirect sunlight. While it can tolerate some direct sunlight, too much can scorch the leaves.
- Temperature: Thrives in temperatures between 60-80°F (15-27°C). Protect from frost and extreme cold.
- Humidity: Prefers moderate humidity levels but can tolerate dry air, making it suitable for most indoor environments.
Soil Requirements
Calandiva requires well-draining soil to prevent root rot. A mix of:
- Cactus mix or succulent potting mix
- Perlite or sand
is ideal for ensuring good drainage and aeration.
Planting Steps
- Choose a Pot: Use a pot with drainage holes to prevent excess moisture.
- Soil Preparation: Fill the pot with your well-draining soil mix, leaving enough space for the root ball.
- Placement: Gently remove the plant from its nursery pot and place it in the new pot, ensuring the top of the root ball is level with the soil surface.
- Watering: Water thoroughly after planting to settle the soil around the roots.

Caring for Calandiva
Watering
- Allow the top 1-2 inches of soil to dry out between waterings. Calandiva is susceptible to overwatering, so it’s better to err on the side of underwatering.
- During the growing season (spring and summer), water more frequently. In the winter, reduce watering as the plant enters dormancy.
Fertilizing
- Feed with a diluted, balanced liquid fertilizer every 4-6 weeks during the growing season to promote blooming.
- Avoid fertilizing in the winter when the plant is dormant.
Pruning
- Remove spent blooms to encourage new growth and maintain the plant’s appearance.
- Prune any leggy or overgrown stems to promote a bushier shape.
Propagation
Calandiva can be propagated through leaf or stem cuttings. Here’s how:
- Take Cuttings: Use a clean, sharp knife to take cuttings of 3-4 inches long, making sure each cutting has a node.
- Drying: Allow the cuttings to dry for a few hours to form a callus.
- Rooting: Place the cuttings in a well-draining soil mix and water lightly. Keep in a warm, bright location until roots develop.
- Transplanting: Once roots are established, transplant the new plants into individual pots.

Pest and Disease Management
Calandiva is generally resilient but can occasionally face pest issues, including:
- Mealybugs: Treat with neem oil or insecticidal soap.
- Spider mites: Increase humidity and use a gentle spray of water to dislodge them.
- Powdery mildew: Ensure proper air circulation and avoid overhead watering.
