Planting background for pond
After much deliberation I have decided to have another go at installing a small wildlife pond. The only spot I can put one is seen here, marked with the X. My previous attempt at pond installing was a disaster so am hoping to get it right this time. I won't be using a preformed liner, that I think was the reason my first attempt didn't do too well!
Obviously there is a bit of work to do and whilst I am still at the planning stages I would like some advice/suggestions on what to plant as a sort of hedgerow/back ground.
The spot in question is running parallel along the length of the greenhouse. I've left a space of around 2ft all the way around the greenhouse (currently a chipped bark path). I've edged on the side you can see with a board to keep the bark in position meantime. Here's a bit of a closer look. I'd like to keep the Photinia Red Robin (not my favourite) but it's now a good size and I think the fact that the stems are bare at the base give it more of a tree look than a shrub. The birds do use this as a perch too. I am thinking that I don't want anything too tall since that would hamper light into the greenhouse but at the same time create something natural looking and of course too benefit to the critters that might like to make my pond their home. Under the Photinia would also be the place I could site a log pile.
Another question is would I be better to do away with the Cornus? I understand that I can keep that in check by annual pruning but I am concerned about its deciduous manner since it is suggested best not to have trees or deciduous shrubs nearby. The perennials all planted in and around the shrubs will all be removed. They were only temporary until the shrubs were a decent size anyway.
So many questions, these are the first of many I will have over the coming weeks/months as my plans progress no doubt. I should add that it's a sunny site and can get a bit wet in winter but obviously not too wet since the sedum doesn't seem to mind.
I thank you all for your suggestions/comments/advice in advance.
