    Drainage holes

    How many inches below the surface of the substrate would be a decent height to put drainage holes for a mini-bog?

    It's a large rubbermaid container, maybe 18x36 inches, 20 inches tall, and the substrate is 16-18 inches deep. It contains Sarrs and drosera. Would 4 inches below the surface of the substrate be enough? More?

    Looking for answers from people who've done this before You know who you are

    Thanks!

    I put mine just at the level of the soil or slightly above it - but then I live in a climate where water is scarce and it quickly evaporates. Keeping that in mind, you may want to ask someone who's made bog gardens closer to your latitude.

    I use plastic litter boxes, without a tray. The holes are about 2 inches below the top of the substrate. I leave the holes unplugged during spring or if expecting storms and plug them up with twigs lying around during the warmer months. I also use dried LFS as a top dressing/mulch. It would also depend on your soil mix. In my conditions the plants do better with a real loose mix with alot of bark and LFS along with the peat and sand.

    Why not use 2 drains so you can regulate the water level based on the season?

    Valve positioning would need to be better than I depicted

    Nice drawing, kayaker78. That's exactly what is needed. I have four drains in each of my bogs at different levels plus an overflow. All it takes is a bad forecast from the weatherman.
