Just remember that compost is very nutritious
and will attrack alot of worms to that area,
which then turn around and eat up that glorious compost and make that lower spot even lower
and possible even looser?????

????
If you know what I mean??
My idea would be to, if you're eyeballin' a new spot for a garden, is to take out/dig that dirt,
and shove it in the low spot *that dirt is alot more solid~er* and then put the compost and cardboard on the newly dug area for a new garden,
then you'd taken out alot of the established
weeds and roots from those
plants that you want to keep out of your new bed..
Make

any

sense??
