Mantas Posted April 21, 2014 Report Share Posted April 21, 2014 Hi, I saw a small plastic garden pond at the shop ant i thought that it would be cool to make a bog in it. It looks like these ( http://lisalines.com/house/wp-content/uploads/2007/10/pond-11.jpg ) ponds. Any advices like how high holes need to be drilled?

billynomates666 Posted April 21, 2014 Report Share Posted April 21, 2014 Hi Mantas, what sort of dimensions has it got and how deep is it at the deep point? The size of the pond could well dictate where the holes have to go to avoid anaerobic conditions that can kill the plants. Ideally if you can drill a series of holes from the bottom to the top at say 100mm centres and put a plastic cork in them, then you can regulate the level to suit the level by the season. For instance in winter take the bottom one out to minimise the water storage and keep the mix just moist during the cold weather and in summer plug them to say 200 mm below the root level or even higher if you want to try a temporary inundation. If it is a small pond and you fill it with substrate with no reservoir at the bottom (upturned plastic pots or similar) then it can become anaerobic fairly quickly if there is standing water.

Mantas Posted April 21, 2014 Author Report Share Posted April 21, 2014 Im not sure about the size because i didn't check. I'd dig it to the ground so it would be like ground level. On the bottom i'd put gravel a bit of peat and live sphagnum mosses on the top. Quote Link to comment Share on other sites More sharing options...
billynomates666 Posted April 22, 2014 Report Share Posted April 22, 2014 In th absence of a definitive depth of pool, a reasonable depth for the first hole, in my opinion, would be a minimum of 250mm below the surface level, but if it is a deep pond go deeper, or to give yourself some options, create an inspection tube inside the bog out of some 100mm soil pipe, with a drain at the bottom of that, so you can monitor the depth of water and release some by pulling the bung at the botton if it starts to get to full for any length of time. High water levels on a regular or consistant basis cause anearobic conditions (bad for roots) and can cause rhizome rot.

Bucket Posted April 22, 2014 Report Share Posted April 22, 2014 Hi Mantas I have something similar and it's excellent for small number of plants, only like billynomates666 already wrote you should drill holes for water drainage which you can close manually so you can control water level I done something different i only drilled holes let's say 8cm from top and water is going out when it comes to that point. Top of bog is always wet but i can say that next year i will completely done different because from my experience it is good to flood plants now and then and with billynomates666 suggestion that is much better solution Quote Link to comment Share on other sites More sharing options...
