Firstly, are you considering the design and architecture of your home when you’re gardening?
For example, a cottage style house will compliment a country style look while a spare, minimalist garden would set off a more modern look.
Proportions should come into play and if you have a large house with a flat front, pretty flowers, you could consider using the plants and midsize shrubs to line a path that are inspired by and complement the shape and size of your home.
