Bright colour tools
If you have some vision, choose tools with bright handles so they are easier to find. Or, paint the handles of existing tools white.
Multi-change tools
Many blind or visually impaired gardeners like to work close to the soil at ground level. Short handled tools are essential for this. You can also find a range of ‘multi-change’ tools, which have interchangeable heads.
These tend to be high quality, but you may want to make sure you can comfortably switch the different heads around.
Other useful items
Sound beacon. This can be used to guide you back to where you were working in the garden. A small radio left playing can also do the job. It can also be useful when mowing.
Kneeler seat with handles or gardening knee pads with straps. These take pressure off joints when working at ground level. A kneeler seat can also be used as a stool.
Bright coloured tape. Useful for marking edges, like the outside of a garden tidy tray, tool handles and garden tables.
Right angle guide. This is a home made guide that can be lain on the ground. It can be useful in large areas, for example when digging or sweeping. They are not very simple to make, though. Find a link at the bottom to instructions.
