Would sequestered iron help?

Unfortunately there isn’t Janeainsworth. I know the simple solution would be to put new shrubs in, that don’t need acid conditions, but often people have donated the shrubs and feel an emotional connection to them.

teabag if the tap water is hard it’s teally better not to use it for watering at all.
Is there any way you could collect rainwater to use instead?

I use Miracle-Gro® Water Soluble Miracid® Acid-Loving Plant Food

Thank you Wobblybits, I knew someone on here would know.

If you are in a hard water area and water via a hose, or if your soil is not acid, sequestrated iron will help. I use it regularly on my acid loving plants.
