Looking to place some plants against the bricks of my house. Not going for a typical raised garden bed, but low key, edging and sparingly planting (20mm - <1m) native plants.
As per pic, exposed house brick is 5 bricks high, these are facade bricks they are not structural.
Total garden would be 7m across house front x 90cm width. I was looking at doing 75 or 100mm high edging, costing up weathering steel or plastic edging. Inclined to spend on steel for its straightness. Was trying to avoid wood (termites, up keep).
I have purchased sealant for the bricks. Polyfilla to patch some facade cracks.
I know to not cover the weep holes. And I will grade soil to grass, away from the house.
What else am I missing?
Do I add plastic membrane to base of planting area?
Do I put in an ag line?
Do I need to add edging to brick side of framing or does it need a full barrier of gravel/rocks to protect the bricks?
note: in heavy rain, water pools against these bricks as the house has design is flat in front with no front guttering.
