I'm thinking of filling a hessian sack with seaweed and hanging in my water butt, has anybody else tried this?
I use a lot of seaweed into the compost bins but never tried it via watering

Never heard of this before, but I don't see what benefit could be derived from putting things in your butt over just adding them to the heap as you already do. Once the nutrients leech out youre left with a messy sack full of stuff which would go on the heap anyway presumably? The water, the compost, all ends up in the same place so addimg this extra step to the process would seem to me to be without merit.

Hmmm, I presume the previous poster never uses liquid feed then? Although I have not done this with seaweed I have done it with nettles, comfrey and horse manure to make a 'tea' that can then be used as a feed, I can't see that seaweed would not have a benefit when used this way, go for it.

Hi, I've made liquid feed with comfrey before but was a seperate butt dedicated to just that, then using the tea as and when required. I took the OP to mean that the seaweed would hang in the butt just for general watering.

Personally I wouldn't because sea-weed contains alginates that would hinder any leeching-out of nutrients. It's jolly good stuff to incorporate into either your compost bins or directly into your soil.

You can buy seaweed feed to water in or spray as foliar feed so I can’t see why not. But I don’t how they make it from the seaweed
