Preparing for a shrub/flower bed
Hi all. I'm new to this forum and I have a question. I have an area right in front of my house that I want to prepare to plant some shrubs and flowers. The size of the bed is about 10 feet deep and 10-12 feet wide. It use to be a row of 4 shrubs right in front of my house, and then a strip of grass in front of that. 3 years ago, I had major renovations done on my house, so the grass got destroyed, alot of dirt from installing a new walkway/driveway also got tossed in there as well. Now, there are of course alot of weeds that grew. Because the amount of dirt is too high (right up against the walkway/driveway) and it is a fortune to get rid of dirt, I plan on building it up a bit more and installing brick edging. My question's are as follows:
1)Do I have to add anything to the soil?
2)Can I just add about 2 inches of new topsoil to what is already there and till it in? (I plan on adding 3 inches of mulch as well)
3)Because it's such an eye sore, I plan on preparing it now, but not planting until next spring. Does this change anything?
