Wildlife pond design
I'm planning a wildlife pond for my back yard.
The dimensions are more or less decided: 3.4m long and 2.2m. wide, bean shaped.
In the middle it will be 1m deep.
What I'm not sure about is how to design the borders for the marginal plants.
My goal would be to put a lot of marginals to make it the centrepiece of the garden (which is not much larger anyway).
I'm thinking about leaving a 40 cm wide shelf all around at 40cm deep.
Maybe another 40cm wide shelf only 20 cm deep at one end.
On the other end I'd like to put pebbles to make a small "beach" and a rockery nearby.
Is it enough? Is it too much?
I've absolutely no experience with ponds, but I've got an a tropical fish tank at home for some years.
