Simplest solution is make sure your compost heap gets *really* hot above
70C will see of almost everything.
But easier said than done. The only time my compost heap gets
noticeably warm is after I've dumped a huge amount of hedge clippings
on it. The rest of the year it's a few weeds here, a few prunings
there, and never enough at any one time to generate significant heat,
even though I occasionally water it with sulphate of ammonia to
encourage the bacteria.
I think my heap has been getting very hot at its core. I have the whole 5ft
x 5ft cylindrical, wire-netting-contained heap wrapped in a double-
thickness tarpaulin to help keep the outside surface moist and warm. The
outside surfaces are still, however, naturally going to stay cooler and
thats where most seeds will survive, I expect.
How long does it take for seeds to die due to old age? Probably a couple of
years, yes?
