Care Guide

💧 Water
☀️ Light Full sun

Arrocillo is a perennial herbaceous plant that favors sunny sites and comes from open habitats, frequently growing in meadows and grasslands. It prefers full sun but can also tolerate partial sun.

Ideal: Full sun
🌡️ Temperature 15–37.8°C

Arrocillo comes from tropical areas, where the climate is generally warm and humid. Consequently, it is adapted to high heat and moisture. It does not tolerate sudden temperature swings and prefers a consistent temperature, so avoiding indoor temperature fluctuations is important. It typically cannot withstand cold and needs warmer conditions to grow. If the surrounding temperature falls too low, the plant may stop growing or even die.

Ideal temperature: 15–37.8°C

🌱 Fertilizer

Arrocillo needs extra nutrients to encourage healthy new growth. In spring, adding some compost around the plant’s base can effectively supply the nutrients it requires. Fertilizing helps support vigorous growth and enables the plant to better resist diseases and pests.

To encourage new growth, improve air circulation, and remove damaged foliage, it should be pruned in early spring.
