Hi
We have a large green oil tank (I think it's 2500litres) in our garden. It's sat high too as it's on about concrete blocks about 6 layers high. I'd like to screen it off. Can anyone help with ideas? I'm not much of a gardener. 
I was wondering about hazel or willow screens. Or what about a bamboo that won't take over the garden? Or is there a climber? Any pointers gratefully received!
Thanks
