Care Guide

💧 Water
☀️ Light Partial sun

Brassia arachnoidea occurs naturally in habitats such as forest understories or rocky sites, where it grows in natural shade. It prefers partial sun but can adjust to full sun or full shade, demonstrating its versatile and hardy nature.

Ideal: Partial sun
🌡️ Temperature 20–37.8°C

Brassia arachnoidea prefers warm conditions. It grows best in moderately high temperatures, but not in excessively hot, humid conditions. Sunlight helps warm the plant and encourages flowering. However, prolonged direct sun in summer can cause sunburn, so the amount of light it gets should be controlled during that season. The plant is generally intolerant of cold, so it needs adequate protection and warmer temperatures in winter to prevent freezing.

Ideal temperature: 20–37.8°C

🌱 Fertilizer

Appropriate fertilization is essential for Brassia arachnoidea's health and appearance. Feed Brassia arachnoidea during the summer, repeating the feeding monthly throughout the season. The nutrients provide energy for growth and help preserve the plant's parts. Fertilization improves Brassia arachnoidea's flower display, helping produce the best blooms.

🪴 Pot & Repot

When repotting Brassia arachnoidea, select a slightly larger pot with good drainage, preferably a clear orchid pot. Use a well-draining, orchid-specific mix that includes bark or moss. Gently clean the roots and trim any that are dead or rotting. Repot after flowering, usually in spring or fall, water thoroughly, and place in bright, indirect light. Avoid disturbing the roots once repotted.
