The ideal temperature range for this plant is between 65°F to 85°F (18°C to 29°C). Temperatures below 60°F (15°C) or above 90°F (32°C) can adversely affect its growth and even cause damage.
Soil Requirements
The Porterandia castaneofulva (S.Moore) Keay plant prefers well-draining soil that is rich in organic matter. The soil needs to retain moisture without becoming waterlogged, as excessive water can lead to root rot. A soil mixture of peat moss, perlite, and sand in a 2:1:1 ratio can provide the necessary conditions for the plant's growth.
Cultivation

It needs a well-draining soil mixture of sand, loam and compost. The plant prefers partially shaded areas but can also survive in full sunlight with adequate watering.
Watering Needs
Porterandia castaneofulva (S.Moore) Keay requires adequate water to thrive. It requires watering once or twice a week, depending on the soil conditions. The plant needs consistent watering during the growing season to maintain a healthy growth and flowering display. However, it's crucial to allow the soil to dry in-between watering to avoid root rot and other diseases that could affect the plant's growth.
Fertilization
Fertilization plays a crucial role in the growth and flowering of Porterandia castaneofulva (S.Moore) Keay. The plant needs a balanced fertilizer with an N-P-K ratio of 10-10-10 or 14-14-14. Apply the fertilizer during the growing season, preferably every two weeks. However, it's vital to avoid over-fertilization, which could lead to salt buildup in the soil, causing harm to the plant.
