How land preparation is done for vanilla cultivation?

The land is prepared by ploughing it a couple of times to bring the soil to a fine tilth stage and to remove any type of weeds that may have been left from the previous crops. If the soil is not fertile, organic manure is added during the land preparation process. Vanillavines require support for growing, so any type of living trees, rock pillars or iron pillars can be arranged for supporting them.
