Grub worms in my vegetable garden.
We received a free truck load of aged manure/compost off craigslist, from a farm here in Colorado. It is riddled with grub worms, in every stage of the life cycle!! Which I have learned is 4 years under the soil, eating roots, etc. before they finally become beetles and fly away.
I've read that milky spore doesn't really work. Or we can cook the soil, which I would have to do at the end or begenning of the season would cut my already shortened growing season even shorter, small price to pay.
Is it as bad as I am thinking, maybe 1 large grub can only eat a little, and is there an organic way to save my garden this year, that is if they are ruining it?
Every scoop of dirt has a few grubs :(
