Growth—

The plant thrives in hot moist insular climates with frequent, but not excessive rain and requires two drier months to check vegetative growth and bring the vines into flower[2]. It grows best in areas where annual daytime temperatures are in the range 21 - 30°c, but can tolerate 10 - 33°c[2]. It prefers a mean annual rainfall of 2,000 - 2,500mm, tolerating 1,500 - 3,000mm[2]. An epiphytic plant, growing in pockets of humus on tree branches[3]. It requires a position in semi-shade, well-protected from winds[4]. Prefers a pH in the range 5.5 - 7, tolerating 4.3 - 8[2]. Plants produced from short cuttings, around 30cm in length, will take 3 - 5 years before they flower and start to produce fruit. If longer cuttings, around 90 - 100cm in length, are used, then fruiting can commence after only 1 - 2 years[2]. Under favourable conditions a plant may grow 60 - 120cm per month[1]. The plant has an economic life of about 10 - 15 years before yields drop and it needs replacing[2]. The flowers usually need to be hand pollinated, especially when being cultivated outside the plants natural range. The fruits mature in 180 - 270 days from flowering[2]. They are harvested when still green and lacking their distinctive aroma, and are then put through a lengthy curing process during which time they turn brown and develop their aroma[2]. Yields are very variable - a good vanillery may yield about 2.5 - 4 t/ha per year of fresh fruit, which gives 500 - 800 kg/ha of cured beans[2]. The flowers are pollinated by a specific species of moth in the night time. In areas where the moth is absent, hand pollination is necessary[4].

Propagation

Seed - surface sow, preferably as soon as it is ripe, and do not allow the compost to dry out. The seed of this species is extremely simple, it has a minute embryo surrounded by a single layer of protective cells. It contains very little food reserves and depends upon a symbiotic relationship with a species of fungus. The fungal hyphae invade the seed and enter the cells of the embryo. The orchid soon begins to digest the fungal tissue and this acts as a food supply for the plant until it is able to obtain nutrients from decaying material in the soil[5]. It is best to use some of the soil that is growing around established plants in order to introduce the fungus, or to sow the seed around a plant of the same species and allow the seedlings to grow on until they are large enough to move. Cuttings, 90 - 120cm long, with at least three leaf nodes. Sit them in loose, friable soil, but do not bury deeply or they will rot[4]. New shoots develop after 30 - 40 days[1]. Cuttings 1.5 - 2 metres long can be taken at any time of the year, but are best towards the end of the dry season[3]. The cuttings are kept loosely coiled in a dry, shady place for 2 - 3 weeks before insertion in open compost[3]. New shoots develop after 30 - 40 days[1].
