Craned neck!

First is Populus candicans 'Aurora'

The second is really an evergreen shrub but can get to 12ft eventually and is called Viburnum tinus.

Thanks fractal and apologies for tilted pix. There is no way i can turn these pix from my sony vivaz as it doesn't let me in the camera nor on the computer.

Hello again, I am doing bit of research on candicans aurora and came with the info that they shouldn't be planted closer than 65 feet from a house. Mine is about 45 feet from my dwelling.

Is it going to be trouble for the house and if so shall I take it out and what else I can plant so that neighbours at the back can't easily look at my house/ garden etc. I prefer a bit of privacy.

Just hard prune it in spring. This encourages plenty of lovely strong new growth (and larger leaves) and helps reduce the vigor of the roots.

So there is no problem as long as I hard prune them next spring?

Yes, pruning reduces the vigour of the roots. If the top isn't large, the roots won't need to grow the equivalent to support it.

Sorry but one more question. Can I apply the same to Betula tree which is closer than this treebut about 7 feet tall and I keep pruning it so I assume I don't need to take that out from the ground either?

Thanks in advance.

You won't need to do this to the Betula. Birch are not like Poplar, Willow or Elm which have very exploratory roots, besides pruning would ruin a birch trees graceful form.
