Water in the Water Butt
woodypecks:
How long does rain water stay fresh in the water butt ? I noticed a bit of a wiff coming from the water inside one of our water butts .....can I still use this ? Or should I tip it all away and start again ? Which leads me to the next question ...How does one clean out a dirty Water Butt ? :coffee2: hmmmm ..... anyone got any good advice on this ? Debbie :sunny:

If nothing gets in there then it should be fine for watering purposes ... but if it's smelly then that's a sign that vegetation (or worse snails) have got in there and have started to decompose. It could also be from a build up of algae which could occur if the water is exposed to light.
It would be better if it could be replaced with something clean ... but if you have nothing else then I personally would chance using it ... rotting organic matter is rich in nutrients and it's unlikely any harmful bacteria are in there that wouldn't be in a comfrey feed ... there's not a lot of rain forecasted for a while so you may need it in this hot weather!

My concern is the use of mains tap water .It would seem logical that chlorinated water would kill off soil bacteria and fungi. Does anybody know of research that would evaluate that? Do you fill your water butt from a hose? If left to stand, it will of course allow the chlorine to diffuse into atmosphere.
Have you noticed any indication that plants prefer rain water?

If the butt is covered then I would not worry. I have filters between the drain pipe and the water butts and they catch quite a bit of organic matter, mostly moss from the roof. Basically a square of fine mesh wedged between the down pipe and the butt. Used to use old socks, but the mesh is easier to clean and reuse. If you really want to clean the butts, they need to be emptied, come out and after upending, washed out with a hose. The base coating of the butt after several years of use is interesting - black , shiny and resembling used motor oil. I have no explanation why.
I haven't washed my butts out for years now and as soon as seedlings are big enough to go into the greenhouse for hardening off, they get butt water. So far no ill effects. :wave:

My gut reaction is that rainwater ... even if a bit stagnant ... is better than tap water. But I don't have any direct evidence that this is the case. Our water here is hard so it might raise the pH too much and I certainly wouldn't like to use it on blueberries or citrus.
