Hi. I have had black membrane down on my allotment plot for at least a year. I think that has killed off lots of weeds but am sure that bind weed will be trying to make a comeback and possibly couch grass but thats probably more likely to come back from the shared paths.
I have made new raised beds with 6 inches of well rotted manure and my question is whether I can safely put asparagus in this spring or if I should wait another year to really get on top of the weeds before planting?
I mulched a low raised bed with 6 inches of council compost which effectively suppressed the couch grass which is my main enemy. I planted asparagus crowns and home grown seedlings immediately after mulching and it seems to have been OK though some ongoing weeding needs to be done carefully so as not to damage asparagus roots.
