Brick wall veg patches / retaining walls - does the inside face of bricks need protection from soil?

[DIYNotIan]

Hi all

I finally got my garden veg patch wall built thanks mostly to my dad, but also to you guys for all the help in other posts. Cheers!

So, now that it is done, I'm wondering (before putting the soil back) whether it would make sense to protect the bricks where the soil will rest against them. If so, what should I use. The garden is going to be organic, so I'd prefer to stay away from anything that will leach nasties into the soil. In all honesty, I'd rather use nothing. But if it will help the wall to last longer, then I'm happy to protect.

Cheers

Honestly, I wouldn't worry. But if you do, line with black polythene (easiest) or bitumen paint (muckiest)

Don't use anything you wouldn't eat. It's a veg patch after all.

Hi

Just resurrecting this thread as there has been a slight change of plan....

Thanks for the previous replies first of all....

The new plan is to finish off the triangular bed with wood (along the unfinished length; see photos). What can I use to protect the wood? Will black polythene as suggested above do the job? And by that are we talking about those damp proof plastic rolls you can get, or pond liner, or some other black plastic? Are there any other options? What would be the most effective and the cheapest?

Many thanks

Max
