In some areas, the plant may tolerate temperatures as low as 50° degrees Fahrenheit (10° C).
As for light exposure, keep the plant away from the full sun.
Part shade is the ideal growing condition for Brazilian-plumes.
Water Needs and Feeding
Tropical habitats mean constant moisture.
During the growing season, the plant should be watered thoroughly with room temperature water.
Be careful about the moisture in the soil, avoiding letting it dry completely. When the Jacobinians are newly planted, water them daily for a few weeks.
Once the roots have established, adjust watering to three to five days apart.
In winter, you might have to spray the leaves with water, especially if the air is dry.
When it comes to fertilizing, an NPK balance of 5-10-5 will work well, encouraging blooming and strong growth.
Use liquid fertilizers, slow-release or granulated formulas. Make sure to follow the package instructions carefully.
Too much fertilizer is damaging for your plant. The package will tell you exactly how, when, and how much feed to use.
Soil & Transplanting
These tropical plants are not very fussy about soil. They can easily tolerate acidic to slightly alkaline sandy, loamy, and clay soils.
Two of the most important soil considerations include fertility and drainage.
Rich, well-drained soil retaining ample moisture is the perfect home for Brazilian plume flowers.

Add organic matter or compost in the soil and place the plant.
Backfill the soil gently, filling the empty space around the root ball and then press it down with your hands.
Grooming and Maintenance
While not necessary, prune the plants freely to maintain the desired shape and size.
Pinch Justicia carnea plants back after they’ve flowered. This encourages better flowering and bushier and denser new growth.
Also, remove old flowers to keep the plant healthy. This also helps prevent self-seeding, which normally takes up a lot of the plant’s energy at the expense of flowering.
