Bringing Calathea Veitchiana to Home

When you get your new Calathea Medallion plant, it’s important to check for pests thoroughly. If there are any signs of infestation on the leaves or soil surface, immediately move the plant onto quarantine treatment. It is preferable to keep any new plant in your home away from other plants for at least two weeks.

Please wait for two weeks after bringing the Calathea home before fertilizing. These plants can be fussy in their new surroundings and require some time to adjust to the new environment.

watering requirements

How often should I water my Calathea Medallion?

Watering houseplants is often a mistake that leads to root rot, fungus gnats, and other issues. Like it’s other family members Calathea Zebrina and Louisae, water your Calathea Medallion thoroughly when you first notice that they’re thirsty. This will help prevent root rot and fungus gnats caused by inadequate watering. The best course of action would be to press the soil gently to check for the presence of water. If the soil in the top 1 inch of the layer of soil feels dry on touch, you can proceed with deep watering of the plant.

Calathea Medallion is more sensitive to overwatering than being dry for a short period; therefore, to be on the safe side, you may prefer underwatering the plant rather than overdoing it.

When watering your Calathea Medallion, make sure you follow these few steps:

  • Always check for soil moisture before watering. Never water the Calathea Medallion if the topsoil is damp.
  • Whenever watering the plant, do it thoroughly so that water reaches up to the roots.
  • Use distilled water for watering. If distilled water is not available, it is preferable to keep the water in a pot for 24 hrs before watering. This practice will help in settling minerals present in water.
  • Do not use cold water for watering. Room temperature water works perfectly for maintaining roots health.
  • Remove any extra water from the pot tray.
  • Adjust your watering cycle as the weather changes.
sunlight requirement

Calathea Light Requirements

Small plants like Calathea Medallion are protected from direct sunlight exposure by canopies formed by larger trees in their natural habitat. Therefore, Calathea Medallion thrives in medium indirect sunlight. Though they grow well with a little bit of both bright and dull-looking indoor environments, however, prefer brighter surroundings for optimal growth.

The best place you can keep this amazing plant is where there’s plenty of natural sunlight coming through windows or east-facing doors throughout the day. However, please ensure the plant is not exposed to direct sunlight; otherwise, they may suffer leaf burn from direct sun exposure on one side only, which turns them into stripes rather than evenly variegated pieces as nature intended.

The leaves will scorch and turn brown when placed under direct sunlight. If you notice that some of your plants’ leaf tips have died or grown dried out because of being in too much light for an extended period, move them away from these harmful sources until they recover. You can also prune dead leaves off, as it tends Calathea Medallion

to grow more rapidly, which improves its appearance overall.

humidity and temperature

Temperature and Humidity

Your Calathea Medallion is beautiful, but they need to be cared for in order not only to survive but thrive. The ideal temperature range for the plant is 65°F – 80° F, meaning that the average room temperature shall be suitable for your plant’s needs. Make sure you keep them away from hot sunlight or radiators because this can cause stress on the plants, which may lead their leaves to curl depending upon how severe the exposure is.

Cold weather is not kind to Calatheas, so you should be sure your Calathea Medallion is not exposed to it. The minimum temperature for this plant is 55°F. Therefore, if you are growing Calathea Medallion outside, please make sure to bring it in once the night temperature drops from 60°F.

Whenever you’re growing Calathea Medallion plants, it’s important to maintain high humidity levels. The ideal humidity level for Medallion Prayer Plant is 50-60%. There are many ways of achieving this if you live in a dry area. The best way is by using a room humidifier if your home has one available.

Otherwise, you can group your plants together to retain the moisture or place the pots over a pebble tray containing water. However, ensure that the water level in pebble trays is lower than the pot bottom. In winter, it’s difficult to maintain the perfect humidity level in your home.

Additionally, you may experience low humidity due to heating and cooling systems. But maintaining optimum humidity level is of prime importance for your Calathea Medallion health. Low humidity levels can cause Calathea Medallion leaves to droop and become crisp.
