I really would like to grow a Gunnera, in my garden.

I have rescued a baby one. Not sure how you tell if they are babies as they're so big !! Sadly my garden is dry shade and I'm creating a shade garden. I don't want to have a pond but is there a way of preparing the soil? Like digging and lining it with plastic or does this create a stagnant mush. Any advice would be gratefully received... thanks.

On plant Gunnera




If its Gunnera manicata it needs a lot of space. Ideally needs to in a bog garden but will grow in dryer sites (leaves may be smaller) although hardy you may need to protect crown from frosts. Although you want moisture you do need it to drain so add plenty of moisture retentive humous in a very large deep whole much bigger than the plant.

It likes a sunny or part shade position in very moist soil, so I'm a bit worried about your 'dry shade' position. Your plant will need a lot of watering even if you create a new environment for it.
As soon as the cold weather comes, break the leaf stems and lay them over the crowns. This should protect the plant, as Drc says.

Definitely needs winter protection as I've lost a couple by not covering them up. A thick layer of straw works well, but don't forget to uncover the crowns in the spring after the last bad frosts.
These are slightly disappointing plants as the ones we see in large gardens are massive plants, but even after three for four years ours are still quite small, although in 'ideal' conditions besides a large pond.
Essex is quite dry isn't it? I would certainly make a good planting hole with lots of organic material to retain moisture, and keep it really well watered during dry periods. It also needs more light than most of us give it! Don't plant in a very shady spot.
