How do you Care for Calathea Flamestar?

Furthermore, scheduled watering, moist soil with diffused indirect sunlight, and a humid atmosphere with the perfect required temperature will boost the growth and freshness of the plant.

The Calathea Flamestar allows you to know its needs if something is wrong with the conditions provided. Here is a complete guide on knowing the Calathea Flamestar and how to take care of it.

Adding Flamestar to your Houseplants

Every plant collector is happy to have a new plant in their plant collection, but there is a catch; the plant may be carrying pests or diseases. Flamestar is a bushy plant, and there could be infestation growing under the leaves. So, you must have a close look, particularly at the leaves of the Calathea Flamestar. To be on the safer side, keep the new plant away from all other plants for two weeks to eliminate any chances of the disease spreading to other plants.

You can place the plant with other houseplants in your garden or its desired location when the quarantine time of two weeks is complete. My routine is to spray my new plants with Instant Plant Protection tablets before putting it with other plants and it has saved me the trouble of having pest infestation many times over the years.
