Hi,
I'm looking at building a new garden at the front of my house.
I recently cut down and removed a large hedge that was blocking my whole facade and now I'm looking at re-doing it all.
I want to plant a couple of native grasses and around 2-4 Callistemons for some colour and wildlife with some bark/mulch base, and edging it with Brighton retaining wall blocks.
My questions are:
1. Can I plant around the previous hedge roots? approx. 4 in each bed, rather than digging them out.
2. How do I prepare the base for the retaining wall blocks? Do I use a compactor and paver sand?
3. Have I missed anything else for preparation? Or should I add anything else?
Thank you
