It's almost that time of year when someone asks about the strange
little eggs they have found in the compost when they are repotting a
plant.
They are not eggs
They are a slow release fertilizer that takes anything up to 12 months
to break down, they do no harm, just feed the plant so don't worry
when you find them.

But where does that fertiliser come from, and how does it get into my
compost heap?
