I am lucky to be Malaysian, living in Petaling Jaya. I have worms thriving in my garden as I am into worm farming (composting to you). I use horse dung as the base and lots of fruit waste (mainly watermelon skin). Of course, worms grow naturally in my garden as I am always digging up the soil to loosen it, transplanting, burying dead fish from my aquarium, etc.
Question: Do worms prefer soil mixed with horse dung or can they do with horse dung and fruit waste only in the worm farm? Or do they thrive better in the ground?
