Hoping someone will be able to help me out, as I don't have much gardening knowledge!
I would like to plant something that will grow to help screen above a fence. The run of the fence is about 30foot. There is already laurel planted in the remaining run, which is in beds that form part of the garden.
The complications are that it will be planted into a bed but the boundary line with the fence on is on paving flags. I was thinking of making a bed using breeze blocks, rather than wood, then rendering it with a coloured render. I could build the bed up inside with the blocks and not actually plant until a few foot up, to help with the height I want to achieve. The fence is 6 foot.
I was looking at a non invasive bamboo, but even those said they can get through brick work etc so that put me off. Any suggestions with what would make a good evergreen screen, grow quickly and hopefully to a good height. Something with the ability to grow 6 foot over the fence height would make me very happy.
Thanks!
