microwaving to sterilize seed before composting?

Will it work? My hot composting game is super lame hence the cantaloupe s in all the grow beds I put my new batch in. Cooked seed won't sprout theoretically. So it should work. Tips?

Will it work? Yes. If you cook a seed, it won't sprout.

Honestly, though, I can't see how this would be a good use of time and energy, or a viable solution for a garden of practical size.

Some of us use a "rot barrel" where nasty seeds are chewed up, free of charge, by anaerobic bacteria. It works, though it takes time, and it stinks like hell. But a year later, you can add this nasty goo, in small amounts, to your compost, force it aerobic, and ultimately it's just plant food. It's lazy and stinky and quite effective, if you have the patience.

My 2c.

Edit: Wait, what, you have cantaloupe growing wild? I personally have some difficulty perceiving this as a problem. But we live in different climes.

The 'rot barrel' also can work on persistent perennial roots like bindweed and docks.
I guess if hot composting is not likely to happen, and I for one have never managed to be that organised with 'browns' and 'greens', then you need to accept that you have viable seeds in your compost.  My way round it is to bury the compost (I only really use it when transplanting, so need to dig a hole anyhow) many weed seeds need light to germinate, so the number germinated is at least reduced.  This probably wouldn't work for your melon seeds though.
Mostly I 'chop and drop', or at least pull and drop weeds, the roots often go in the compost heap.  I only turn this once a year or so, and then it sits for another year before using, so most seeds and weeds have given up by then.

no, melons are not a problem. Unless you figure not the expected Patty pan or cukes. I have to find recipes.
