My father always said that putting manure down would result in an
allotment full of weeds. No idea if this is true or not. Anyone got an
opinion?



Depends how you make the compost.

In one go: Fill a 1m^3 compost bin with mixed greenery including weeds, and
it will get hot enough to sterilise the weed seeds in the early stages of
decomposition and worms etc will come in to do the rest.

Dribs and drabs: Plonk a bit of greenery on as when whim takes or the
weeding basket is full and the heap will never get hot enough to sterilize
and the result will be weed seed in the compost and a weedy allotment. This
is in fact what most of us do and in truth most of our compost heaps are
just big worm-bins! If you do it that way you must be religious about not
putting weeds in seed on the heap. General pruning, vegetable waste, veg
patch clearings - all are fine: But no weed seeds!
