Hi all,

this is my first time posting here and first time DIY’ng my backyard.

plan is to layout artificial turf+ deck+ walking path to deck.

I have a clarity for artifical turf, where i need weed mat+ crushed rock+ dust as a base and top will be turf.

but for edging between turf and walking path, how do i proceed?

do i first layout weed mat for whole area or cut out different mats for different paths.

does eding needs a trench to sit properly or is there an option to just nail down?

can i use same edging between deck, walking path(pebbles with steps) and turf
