Aa I cannot apply rainwater any advise would be welcome on reducing the
impact of hard tap water on my Rhodos, Azeleas etc. I can put on
Squestrone and tea from time to time but the regular watering is thro
an auto hose system. Are there filters or lime neutralising slow
release chemicals?
Thanks

A water softener should help, also try feeding the soil using Ferrous
Shulphate.
