The main difficulty in growing vanilla is it requires a lot of room. It grows as a vine and grows many feet in length. Provide a pole or support for the plant to climb and allow the aerial roots to attach. It takes many years for vanilla to bear fruit. The vine usually has to be 15 feet or longer before it bears fruit.
Vanilla have clusters of small, yellowish flowers.
Hand pollination is necessary when the plant flowers in order to get fruit. I personally do not have any vanilla orchids. Until next time, Vivi P.S. Spring is the time for new growth. Remember to give ample water and fertilizer during this time. Also, think about repotting your orchids now.
