Any Old Iron!
Sam was an old chap who lived in the house we have now, when we bought the house the garden was in a bit of a mess, Sam passed away 9 years before.
Now Sam had carried every bit of soil into this garden, from the road when it was brought by tipper lorry.
The garden was once a turnaround for horse and carts, and later coal lorries, well Sam realised the road was going to waste, so in came the soil to a good depth of 2 feet and sloping, so it was a mammoth undertaking, the little walls he built round it, are still here in places.
Now I had a task and half clearing it up, and I promised Mrs Sam that we would return it to it's former glory, one thing she asked was to keep his hydrangea which was his pride and joy, she mentioned that Sam had told her that to keep it's nice vibrant colour, you must give it plenty of iron, he used to throw old nails and metal bits from the garden, even a carthorse shoe, which I still have, and a gorgeous victorian hanging bracket.
We religiously we cut all the dead out in April, and I still throw the old iron bits there, and of course I talk to Sam, for I am sure he is still here, because I was never a big gardener but I love it now.
What a long drawn out story just to give you the tip about the old Iron.
