Hello Mike,
Thanks for the suggestions. The bathtub method seems very practical and less time-consuming. But that is out of the question unless I draw up my divorce papers prior to doing that

. My wife is already complaining about my hobbies and my encroachment into 'her' areas as well!!!
I have not found any negative symptoms yet but it is perhaps too soon to tell. I will have to wait until the temperature outside rises up to at least to 20C before taking the plants outside for extended baths. That is at least 8 weeks away. I will try 'flushing' the pots individually over the next few weeks.
I would not recommend trying to handle a whole coconut. Chain saw or circular saw does not work. Anchoring it in any form is a Herculean task.
Luckily for me one of my friend's father-in-law, who is from the east, helped me with husking ,using a huge 'scary looking' cleaver/scythe. He was very adept in using it. I failed miserably
I will begin flushing the pots tonight.
Thank a lot!
