Raised beds - help re AstroTurf and depth
Hi all.
Our back garden has some AstroTurf - it's fairly small and we can't afford to change it (plus have a big dog so it's quite practical) - and yes, I hate it too.
We are planning to build some raised beds with some sleepers we were given, likely on top of the astro area. Questions:
- We are planning to go two sleepers deep - 40cm - is that deep enough for some nice plants? Ferns, etc.
- Would you pull up the astro underneath or leave it? It drains very well. There is some sandy gravel underneath it, unclear how deep. I plan to use a membrane of some type to line the beds.
Thanks!
