It will take care of the light needs of plants in the required range.
• Window: You can also put your plant near a permanently closed window with no other light source nearby. Sunlight will maintain the diurnal cycle of the plant and the window will filter the light for the plant. Other light sources can disturb the diurnal cycle of the plant.
Calathea Medallion Soil Requirement
Calathea medallion shows good growth when it is planted in soil that is best able to retain moisture content. This plant is not tolerant to dry environments. Different combinations of organic materials are used for soil to propagate and grow Calathea medallion. Peat, perlite, coco coir, and pumice all are used as far right soil combination is a concern.
The main requirements for optimum soil medium are mentioned below:
- The soil must retain moisture.
- Soil should allow oxygen flow for roots and plant growth.
- No waterlogging should happen.
- Proper drainage system for extra water.
- Maintenance of soil pH around 6.5 for optimum growth.
As far as soil organic material is related peat is used for the organic layer of soil surface that is made of partially decomposed organic matter mainly consisting of plants. Coco coir is mainly sourced from fibrous husks of coconuts. Perlite is created from volcanic glass where the raw composition consists of water, trapped by the rapid cooling of lava. Different combinations and mixtures of these are used as soil mediums for Calathea medallion growth and propagation. Mostly a good mixture containing 2/3 parts of peat or coco coir and 1/3 part of perlite is considered the optimal mixture as soil medium. This mixture makes an oxygenated combination of soil that can retain moisture.
