My DH and I are novice gardeners with a tiny London garden. Neighbours have put up new fences so we need to plant some stuff to cover them quickly. What would you recommend? Thinking some flowering evergreen climbers would be good. Or semi evergreen though I'm not sure what that means. It's sheltered and both fences get some sun, the side one only a little but the back one from late morning till about 5pm. And what about the borders? Keen to make the garden lovely but we are clueless. Thank you!
