Are iron filings good for the garden. My husband is an engineer, and has been working on cast iron.Would the garden benifit from them.
The ground is rather alkaline in composition.



I think they would just stay there rusting, you could take them to metal recycling?

They help to turn pink hydrangeas blue, other than that, none that I can think of.

I wonder if they would keep snails and slugs away from tender plants and seedlings if you sprinkled them in good measure around the plants you wanted to protect?

i tell you what they are good for.if you dip them in salt water and take them out a few times then do a runny cement mix with plenty in and coat something pottery or cement in it it will run rusty and looks realy smart.

If the soil is alkaline, they will just rust without releasing enough soluble iron to help anything. Try mixing them with dusting sulfur before spreading them--that will turn at least some of the iron into copperas.
