Russian Comfrey Fert

cantharis · #1 (**permalink**) 07-12-2008, 05:53 PM

I make a kick-ass organic fert from Russian comfrey, which I swear by, I thought I would write a thread outlining my method.

First obtain some roots of Russian comfrey, type Bocking 14. A quick Google will find you a supplier, they come as roots, about a euro a root. This is the only time you will have to buy anything. Plant the roots as directed by the supplier´s instructions.
Here is my comfrey bed.

Pull off handfuls of leaves, stuff them in a large plastic bottle about half full of water, until the bottle is full, like the pic below.

Every day give the bottle a shake, undo the cap slightly to release the gases that build up - they smell like a fart to be proud of. After a fortnight top up the container with more leaves, keep shaking and releasing gases.

After a month you are ready, your bottles look like this, full of a brown, incredibly smelly, mix of liquid and plant solids.

Pass through a sieve to drain off the solids. The solids can be added to compost, used as a mulch or dug in to MJ or other crops.

The liquid is your final product, contains N, P and K, mix 20:1 with water, feed often.

You can strip the plants 3 or 4 times in a season.

hay man.. couple questions about this.

1. do you recommend this for both veg and flower periods?
2. does comfrey require a fairly sunny spot to grow or is semi shady ok?

thanks again.,

i think you can actually do the same thing with stinging nettles .

Yes, I use it for both. They do like plenty of water. Mine grow in a fairly sunny spot.

Thats great, you don't have to buy many nutrients I see.I've also heard of making an oak leaf fert the same way, I'll try it out sometime.

I am doing the same kind of thing, except I use Great Mullien and Wormwood leaves.
The Great Mullien ia a local plant for me, some call it a weed, but I found some and
propagated a few plants and now I grow enough to get about the same amount as you do.

I dont know why I add the wormwood.. i just grow a lot of it and it grows rapidly and
takes well to being cut back. So I throw it in.

I'm looking to add even more.. maybe I'll get some Russian Comfrey to add to the mix.

Good Advice!
