Derek,
Thank you for the tips. How long does stuff generally need to compost
for in order to kill the seeds?

It's not a question of time but temperature. If you were to get a cubic
metre (about a ton) and use pallets/carpet/bubble-wrap to make a 1x1x1
cubic insulated 'bin' and fill it in one go it ought to heat up quite
quickly. 60-70 Celsius should do the trick. Others may know better but my
guess would be an original hot compost for about 3 months (keeping an eye
on moisture content) followed by a good turning over and watering and then
another 3 months. Compost can then go on the lawn after the last cut in
the autumn and have all winter to be incorporated. Or a smaller quantity
in a compost tumbler would be ready even sooner.
