I am getting ready to start planting seedlings out in my allotment. Reading online the advice seems to be that I should prepare the ground about a week in advance by digging through compost etc, and for some veg such as squash’s I should dig a hole a spade width and depth and fill it with a mix of compost and soil.
Can someone please explain the benefit of doing this a week before as opposed to day of please as I can’t find that online anywhere.
Just for added info. I have dug over and created my beds already in my allotment, when I took it over it was covered in weeds and grass so used black plastic to help control and kill back as much as possible and then double dug over for the beds (dug out 2 spades down and then put the remaining grass etc at the bottom and covered over.
So the beds are dug raked and any weeds appearing over the past 3 weeks have been pulled. So do I still need to dig in my compost/manure a week before planting in?
