The pleasure of gardening involves growing plants; caring for them, including re-potting, training, pruning and harvesting; maintaining the lawn and the soil and of course using lots of tools! No gardener would be without their secateurs, loppers, trowels and other treasures as each one makes the task a little more pleasurable. A quality garden tool will last for years - even a lifetime.
Likewise, garden storage for logs or even bikes can provide a really valuable service. Consider adding a living green roof if you want to introduce a little biodiversity. Your storage space will then transform into a thing of beauty and become a talking point!
