Default slug and snail control

Hi Sameer, I just read on another gardening group that if you sprinkle
ground, un brewed coffee around the garden it will kill slugs.


Coffee trees produce caffeine as a self-defence insecticide. This is
why coffee from different regions has different levels of caffeine,
varying with the amount of predators.

One of these days I'll try some of my old instant coffee on my roses to
see what it does for aphids and mites.
