The above photographs show the Ketapang leaves being used, my friend advocates the use of fresher leaves (collected while they are still reddish or yellowish) instead of the drier type so they looked rather fresh even though they have been collected for a few months already. These are the photographs of me washing the leaves in water and then scalding them with hot water for a mere minute. Notice how brown the water became because of the fresher leaves being used.
The final photograph shows the leaves after the washing, being stored in an ice cream tub. Hopefully they will decompose well and could be used in a few months time by mixing with other substrates!
