I am known as The Worm lady and I sell my bins at pour local Organic Market on Thursdays and Saturdays. I began Worm Farming on a large scale, feeding manure to my four huge pits of worms developed over two years from 20 sq m. After the death of my husband I had to give my worms to a friend who has made a great success of the worms and I now buy worms and bins from her and sell them at The Bryanston Market in Johannesburg.
I'm a bit "old school" when it comes to harvesting and use the "pile and light" method. I found a video on youtube showing a rotary harvester. I'm not sure if these folks are members here. Here is the link to the video:
I just put the worms and castings in a tall, pointed pile (outside in the light) and the worms start migrating to the middle. Then I just scoop away the castings from the top and end up with a big pile of worms at the bottom. If time permits, I will go through it and pick out eggs.
Have a great day!
One of my worm friends have a copy and I borrowed it. impossible to get I've tried
Will let U know if I can find the book I want one to its excellent!
I am from Mossel Bay and do love gardening with my worm friends.
I read a comment you left on another page about pineapple killing worms. I had a pineapple last week that we fed a few small pieces in our bins. It's gone now. I didn't notice complete death, but it may have reduced the worm population a little. I don't know for 100%.
