A good quality tool - is a thing of beauty - and a pleasure to use. But a good tool - does not make a good gardener. And it is not necessary to have £1000's worth of tools.
When starting out - keep it simple until you need more. Always buy a tool - when you definitely need it. My tool shed is full of tools I don't use.....
Get the following as a new gardener -
1) A good spade and perhaps a fork
2) A trowel
3) Some gardening gloves
4) Secateurs
5) Shears
6) Loppers
7) Lawn Mower - electric to start with
That is it. Second hand tools are perfectly fine to start with. When I started Kingdom Plants - I could not afford my own tools - so I begged and borrowed. Until I could get my own tools.
