I have grown young Gunnera successfully in pots without drainage holes, but in dry weather this can be a death sentence for a large plant. Remember a general rule that the amount of water a plant needs is comparable to the surface area of leaf it has, so Gunnera need A LOT! basically a mature Gunnera needs to have most of its roots very wet to water logged all the time. hope this helps. :D

they need lots of water to get to the giant sizes we all want so i had an idea.

if you buried a bucket a foot or two underneath the gunnera would that provide the roots with a little reservoir so it wouldn't need to be in a bog garden?

i have read soil will sour if kept wet ,eg planting gunnera by a pond instead of by a moving stream so i also thought the bucket should be full of perlite


I have a very free draining garden and have tried your idea on other damp loving plants. unfortunately it didn't work for me but you may have better results. icon_thumright
