Gardeners and growers have been inventing tools to help them in their work since time began. Here are some of the very best invented to date. We've selected hand tools that we know work, and won't let you down when the going gets tough. There are also ergonomically designed, and left handed tools, for even better working when you've a lot to do. Start with the essentials; a good trowel and fork (a good one can last a lifetime) and then add other tools as you progress. Get a bag to put them in as you are moving round the garden, otherwise you'll lose them!
