Does your garden look like this?
Then it is perfect for creating a romantic, woodland garden, like this.
Most of us enjoy a sunny spot but there are always areas in an urban garden which are shaded by large trees, often not even your own so we just have to make the best of it. Wildlife, on the other hand, adores these secret shaded spots so you’ll be doing them a favour. Use natural materials to enhance the structure and shade loving plants, forget the lawn and mulch over pathways through the trees and shrubs.
Layer your planting like in a real woodland, even if you are using a smaller scale with small trees like acers under planted with shrubs, bulbs and then ground-level creepers.
