Goeppertia, Silver Plate / Calathea, Silver Plate

Transplanting:

• Every 2 to 3 Years:
  Repot the Silver Plate Calathea every 2 to 3 years or when it becomes root-bound. Choose a pot that is 1 to 2 inches larger in diameter than the current one and refresh the potting mix to provide new nutrients.

Light Conditions:

• Indirect Light:
  The Silver Plate Calathea prefers bright, indirect light. It thrives in filtered light conditions and can tolerate low light, but too much direct sunlight can cause the leaves to scorch or fade. Place it near a window with sheer curtains or in a shaded outdoor area.
• Indoor and Outdoor:
  The Silver Plate Calathea is versatile and can be grown indoors or in shaded outdoor areas in the Caribbean. It’s perfect for bathrooms or kitchens where humidity levels are naturally higher, or as a lush addition to a shaded garden.
• Shade Tolerance:
  While the plant can tolerate low light conditions, too little light can cause the vibrant leaf patterns to fade. Aim to provide a balance of bright but indirect light.

Temperature and Humidity:

• Warm Temperatures:
  The Silver Plate Calathea thrives in temperatures between 18°C to 27°C, which aligns well with the Caribbean climate. It should be protected from temperatures below 15°C to avoid stress.
• High Humidity:
  The Silver Plate Calathea loves high humidity, typical of tropical regions. Our natural humidity levels are usually sufficient, but during particularly dry periods, you may need to increase humidity by misting the plant regularly or placing it on a tray with water and pebbles.

Soil:

• Use a well-draining potting mix that retains moisture without becoming soggy.
• Use a mix of peat, perlite and potting soil to provide the right balance of moisture retention and drainage.

Watering Frequency:

• Keep the soil consistently moist but not waterlogged.
• Water the plant when the top inch of soil feels dry to the touch.
• Use distilled or rainwater if possible, as the Silver Plate Calathea can be sensitive to chemicals in tap water, such as chlorine and fluoride.
• While the plant enjoys moisture, make sure the soil drains well to prevent root rot.
• Ensure the pot has drainage holes to allow excess water to escape.

Amendments and Fertiliser:

• Feed your Silver Plate Calathea with a balanced, water-soluble fertiliser every 4 to 6 weeks during the growing season (spring and summer).
• Reduce feeding in the fall and winter when the plant’s growth naturally slows down.
• Over-fertilising can lead to leaf burn, so follow the recommended dosage.

Pruning and Maintenance:

• Remove any yellowing or dead leaves to keep the plant looking vibrant and healthy.
• Regular pruning encourages new growth and prevents the spread of potential diseases.
• Gently wipe the leaves with a damp cloth to remove dust and maintain their glossy appearance. This also helps the plant to photosynthesize more efficiently.

Pest and Disease Control:

• The Silver Plate Calathea is relatively resistant to pests, but it can occasionally attract spider mites, aphids or mealybugs.
• Inspect the plant regularly and treat any infestations with insecticidal soap or neem oil.
• Avoid overwatering and ensure good air circulation around the plant to prevent root rot and fungal diseases.
• If leaf spots or other issues appear, adjust watering practices and remove affected leaves.
