Help please - we have not had enough rainwater here to keep watering my 3 new blueberry plants; can I use cooled boiled water instead.
You can draw off mains water and let it sit for 48 hours, that will de-chlorinate it and it can then be used on your plants.
...as an addition I would add a couple of unused tea bags to the tap water in a watering can, before resting it for 24 hours, as it is supposed to acidify it, suitable for Blueberries and suchlike...
A tbsp of vinegar to a gallon of water will acidify it too. I use it every third or fourth time I water my toms in the ground. The soil here is utterly alkaline - the peninsula is mainly limestone - and the water is equally so.
