I have an old Cold Water Tank 25 gallons which I am thinking of using to make Comfrey liquid feed in.

Picture here..

When making Comfrey liquid feed…

Does the container have to be air ?

If I fill the container full of Comfrey leafs how much water should I add to it?

I thinking I will put the leafs inside a hessian sand bag (Wickes 70p) so it does not clog up the tap I will fit to the tank.

When using the comfrey feed how much should I water in down by?

Worried I will use it on the plants and be too strong and or too week.

Good question - I didn't know either. I made a small sample in a 2ltr bottle earlier and left the top off to allow fresh air  in and the smell out.

If I fill the container full of Comfrey leafs how much water should I add to it?

You mean fill the sack rather than fill the tank? either way Id just fill the tank. As far as I can gather the water just aids the process of decomposition. If you have too much water, you dilute less - too little and you dilute more.

When using the comfrey feed how much should I water in down by?

Dilute to "tea" colour, Id get the feel for it but just turning the water brown and seeing how the plants react, gradually increasing the strength.

I assume you've read the info page on comfrey?

Oh yes, definitely vent!  Comfrey tea will cross your eyes!   :wacko:Why not start out with lots of water/comfrey leaves, as it's better to have a weak solution than to burn your tender plants.  You can always make it stronger by adding more comfrey!

Well, I think it can all get a bit too scientific at times, this gardening lark! :blink:
I fill (ish) a large old resealable paint 'tub' with the leaves, and bash 'em to bits with a house brick! then add water - How much is a guess, but about 2 litres I'd say. Put the lid on and leave to 'soak' for about 3-4 weeks.

When it's stewed to a nice black colour, add in droplets to the watering can, until it looks like 'weak' tea. WARNING! - IT STINKS!!!!!!

Thanks.

I started some last night in the water tank but I am now having seconds thoughts!

I tried some in a 5 litre water bottle about 6 weeks ago. I smelt it last week and thought it was pretty bad! but then last night  I spilt a about a 1/2 a cup full on the greenhouse floor (on purpose) to see how bad it would smell in there!  OMG. 
What have I done!   

How long will this smell last for?

My plot is in the back garden so I am really not sure about using the Comfrey  feed now! Was hoping to use in the flower beds as well.

any info on how long will this smell last for? See above?

I made some last year - never again  - after I had used it I could still smell it on my hands 2 days later. I'm thinking of filling up a super-soaker water pistol with it, then hiding in the bushes to squirt the vandals  would this count as assault?
