Interesting Mo, heard of the nails thing; same deal I guess.............can't control the supply rate either, surprising it doesn't ever hit toxic levels. Never messed with gardenias...... can't smoke or eat itHahaha! Sorry - dilute the solution after you have dissolved the minerals for a week in a glass jar.
I used this method with vinegar and steel wool for my gardenias at the old house. Dried out the rusty steel wool clump and buried them in the soil. They loved the acid and iron. Was taught this trick by a Hawaiian gardener who used rusty items in his garden to keep a constant supply of iron going to the soil.
Cheers,
Mo
