Hard water and Rhododendrons on London balcony
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 |

I have an small "acid bed" in a chalky area (a bed lined with plastic sheet pierced for drainage and filled with appropriate ericacious compost). I try and water it with rain water as the mains water here is about 7.8. However my rainwater collection facilities are not very voluminous and I was wondering if the addition of nitric acid to the mains water as practised by hydroponic gardeners might be a thought I could entertain. I know it wouldn't have much effect on my normal soil with all its built in PH buffers, but might it be a good idea to maintain the acidity of ericaceous compost and counteract any alkalinity creeping in from the surroundings? My Rhododendron is definitely sulking. Hussein Grow a little garden |
