Calathea Medallion Temperature Requirement

All plants show good growth at some temperature known as optimum temperature, and it is the same for Calathea medallion. It shows appropriate development in temperature between 65°F to 85F°. It is one variable over which you have no control until your plant is inside the house. When your plant is inside the house you can adjust the temperature with air conditioners and other equipment.

It is better if you place your Calathea near a closed window where light is falling indirectly because you have adjusted the temperature inside the house and also got the right sunlight for the growth of your plant. Calathea medallion can grow well in warm temperature environments but can also tolerate a little cold environment.

In any case, in tropical areas temperature change is major from one country to another. That is the reason it is hard for any of us to satisfy the optimal conditions of the plant.

Direct sunlight can burn your Calathea medallion beautiful peacock pattern leaves. It can also result in the yellowing of plant leaves or damaged leaves.

Product And Recommendations For Light Maintenance

Green House: If you are a plant lover with a large collection of plants with the same requirements as Calathea medallion, Calathea ornata, and other related species, then It is recommended you use a greenhouse with a good temperature maintenance system. 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.

Where using organic and natural material as soil medium allows Calathea medallion to absorb nutrients in a better manner and show better growth. Because this plant shows better adaptation to natural soil instead of an artificial one.

  • Soil Activators: There are a lot of custom-made products and vitamin solutions knowns as soil activators which increase the aeration and water-holding properties of the soil and plants.
  • Peat Moss: Use the sphagnum peat moss for your plant because it is soft, mixable, lightweight, and also has the ability to retain moisture.
  • Pine Bark Fines: It is a cost-effective material as compared to peat moss products. It has the ability to mitigate soil-borne diseases and also maintain the require acidic pH for Calathea medallion.
  • Coco Coir: It is made from the fibrous material present on the coconut shells, it helps Calathea medallion to grow sturdy roots.
  • Perlite or Vermiculite: It has excellent water retention and drainage properties, mostly used for plants that require more water. It is important for the healthy growth of roots.

Calathea Medallion Water Requirement

Calathea medallion is a tropical region plant that needs a good amount of water and moisture for optimum growth. To take good care you need to be aware of Calathea medallion watering needs
