These great little seed sowing tools will help you measure your seeds evenly across a row. I remember being very chuffed when my Dad let me use his one of these to sow radishes when I was a tot.
Now I know it was to stop me emptying a whole packet of seed in the first part of the row! He's still got the same little seed sower and reckons they're a handy thing for sowing a nice even row of fine seeds like parsnips, lettuce, carrots or radishes.
With the benefit of a few years experience, I have to say now I agree with him. This seed sower has a dial with 5 size settings so you can adjust the flow depending on the size of the seed you're sowing.
