I started growing vanilla plant a couple years ago.
I tried to find best place for the plants, but I could not find it and the plant had been getting die.
I finally found really good place after trial and error a year ago.
They look healty now, do they?
They are on the stone wall and The shade provides from a big lytchi tree.
Vanilla plant is like beans plant that they need the place leans on like ivy.
They need also shade and little bid dry soil.
I heard they grow under big tree in wild.
They produce 3 to 5 inches black beans.
That is my hope.
