Calathea Picturata Argentea Silver Variegated Prayer Plant 12cm pot

Care Guide

Light:

• Calathea Picturata Argentea prefers bright, indirect light. Too much direct sunlight can scorch the leaves, causing them to lose their signature colour. Low light is tolerated, but it may cause slower growth. Ideal placement is near a north or east-facing window.

Watering:

• This plant thrives in consistently moist soil, but it should not sit in water. Water when the top inch of soil feels dry. Use filtered or rainwater if possible, as Calatheas are sensitive to fluoride and other chemicals in tap water. Overwatering can lead to root rot, while underwatering may cause the leaves to curl and dry out.

Humidity:

• Calathea Picturata loves high humidity levels, ideally between 50-60%. Regular misting, placing the pot on a tray of pebbles with water, or using a humidifier will help maintain the right humidity. Dry air can cause the leaves to brown at the edges.

Temperature:

• This tropical plant prefers temperatures between 18°C and 24°C. Keep it away from cold drafts, open windows, or air conditioning units, as it dislikes sudden temperature changes.

Soil:

• Use a well-draining, peat-based potting mix to help retain moisture without becoming soggy. A mix of regular potting soil with some perlite or orchid bark works well to ensure proper drainage.

Fertilising:

• Feed your Calathea monthly during the growing season (spring and summer) with a diluted, balanced liquid fertiliser. Avoid fertilising in autumn and winter when the plant’s growth slows down.

Pruning:

• Prune away any damaged or yellowing leaves to maintain the plant’s health and appearance. This will also encourage new growth.

Repotting:

• Repot your Calathea every 1-2 years in spring to refresh the soil and provide more room for growth. Choose a pot that is slightly larger than the current one, and make sure it has drainage holes.

Troubleshooting

1. Why are the leaves on my Calathea turning yellow?
   • Problem: Yellowing leaves can be caused by overwatering, leading to waterlogged roots. Another possible cause is exposure to direct sunlight, which can burn the leaves.
   • Solution: Ensure you are watering only when the top inch of soil is dry and move the plant to a spot with bright, indirect light.
2. Why are the edges of my Calathea’s leaves browning?
   • Problem: Browning leaf edges often occur due to low humidity or fluoride in the water.
   • Solution: Increase humidity levels around the plant by misting regularly or using a humidifier. Try watering with filtered or distilled water.
3. Why are my Calathea’s leaves curling?
   • Problem: Curling leaves usually indicate that the plant is thirsty or is in an environment with low humidity.
   • Solution: Check the soil moisture and ensure the plant is receiving adequate humidity. Mist the plant and water thoroughly if the soil is dry.
4. Why is my Calathea not growing well?
   • Problem: Slow growth may result from insufficient light or nutrient deficiency.
   • Solution: Ensure the plant is placed in bright, indirect light, and fertilise during the growing season to promote healthy growth.
