Vanilla plants have a high water content, with only 10% solid matter. Leaves contain 92% water, and stems contain 89%. This makes them highly susceptible to drought. Cultivation requires an environment with abundant water supply, calm winds, and high humidity. Barriers should be erected to maintain air humidity at 70–80%. Covering the roots with materials like wood chips, dry leaves, or straw (disinfected) helps reduce water evaporation, keep the soil moist, and ensure adequate water supply to prevent plant dehydration.Spray irrigation is used to increase air humidity and maintain soil moisture at 25–30%. The optimal soil pH is around 6.0–6.5 for normal growth.

Vanilla is a temperate plant that thrives in warm conditions. The average daily temperature should be 21–29°C, with the optimal range being 25–29°C. During Taiwan’s winter cold snaps, prolonged low temperatures may cause growth retardation or frost damage to tender shoots.

The differentiation of vanilla flower buds occurs in winter, requiring a period of low temperatures. The suitable average temperature is around 15.5–27.8°C. With the arrival of spring, flower buds will emerge from the nodes.

Vanilla is a perennial herbaceous vine from the orchid family, preferring to grow in partially shaded environments. Direct sunlight or excessive light can scorch tender shoots, causing leaf discoloration, black spots, wilting, and withering. Before planting, install trellises and use 50% shade nets during the growth period to promote healthy plant development.

The soil must be well-aerated and well-drained to prevent waterlogging and root rot. Use a mix of peat soil (4:6 ratio) with easily obtainable substrates like coconut coir, bark, expanded perlite, bamboo charcoal, or tree fern fiber. Apply orchid liquid foliar fertilizer (balanced type), diluted, 3–4 times a month. Organic fertilizer should be applied to the soil once per season.

Under suitable environmental conditions and proper management, flowers will bloom around April to May after 2–3 years.
