Planting into manure on top of the cardboard mulch
Just wanted to double check something as I begin preparing the beds for no-dig.
I have some perennial weeds (couch grass being one). Because of this, I am aiming to put down 2 layers of cardboard then top that with 6 inches of rotted manure/compost mix. This I hope will be enough to exclude light and, over the next year, kill off perennial weeds as well as the annuals.
My question is, can I plant straight away into this compost layer, even though it has cardboard underneath? Will the cardboard prevent roots growing down properly i.e. will it be in the way?
In an ideal world, I would leave the beds with the mulch for a year but I really need to make them work straight away. Digging out all the perennial weeds first is also not really an option because of current bad back! Any advice would be much appreciated.
