How to make organic garden fertilizer

Hello, my names Katie Rushworth. Today I am going to show you how to make fertiliser
from nettles. Now nettles have a terrible reputation of
being incredibly invasive and things that nobody wants in their garden, however they
can be really beneficial. You can’t use them in the compost because
they will spread that around your garden to feed your plants, you will also get lots of
nettles coming up everywhere. You can make liquid fertiliser out of them,
and that is what we are going to do today. Now I have picked all of these nettles and
in spring the new growth is excellent for this. But first I need to chop them up a little
bit smaller to aid the decomposition of them. To do that I am going to be brutal and use
a spade. Now so far I haven’t been stung but we have
a little way to go yet. So we have to bruise the stems and the leaves
as much as possible and that will just speed the whole process along. You can also use comfrey to do this. Comfrey is an excellent liquid fertiliser
but I want one that is high in nitrogen. Because nitrogen is excellent for foliage
plants, leafy vegetables need high nitrogen content feeds and this is going to give us
that. I think that is about it. Now I am going to use this lidded bucket,
you can use anything but a lid will help enormously because unfortunately this is quite a smelly
job. You know that the fertisliser is ready when
it smells terrible. Right now this has that fresh green smell
now I have chopped it all up a bit like freshly cut lawn. I am going to pack them down and then I have
some rainwater which I am going to just cover the leaves with. This will be wonderful fertiliser for things
like evergreen shrubs, lettuce, cabbage, anything that is grown for it’s foliage. I think we are just about there. OK. And now I am going to give them just a little
bit of a push down again into the water, submerge them fully and then pop a lid on. And that wants to be left somewhere away from
the house so you can’t smell it and nowhere too sunny. Now this has been here for about 4 weeks,
and I am really quite excited to see what is in it. Well it is definitely potent, and it is definitely
green. Look at that! It looks amazing, full of the good stuff. Now I need to drain, sieve all those left
over bits of nettle out. So to do that I have a sieve, and I am just
going to pour this through here. OK. Fortunately because of the weight of the foliage
it all tends to be staying at the bottom anyway. OK, I will just utilise this stick and try
and clear the mesh from the bottom of the sieve. I used to this kind of thing when I was a
kid, making potions, that is what it feels like. You could also use this as a folia feed. SO if you wanted to put it in to a spray bottle
and spray the foliage of things that would also work wonderfully. And to put this on to my plants and feed my
containers I will actually be diluting it, one part nettle feed to ten parts water. But it is brilliant accelerator for your compost. So if you wanted to put some of this neat
undiluted fertiliser directly onto your compost it would really accelerate the decomposition
process and give it a real boost. I think we are almost there. OK. Now where did my, oh it is there, and there
we have it! So I am going to take one pot of this, dilute
by ten and feed my vegetables! Free fertiliser made from nettles, wonder
stuff! For more how to videos visit

  1. You can stop the smell if you aerate it and besides that it actually helps the beneficial aerobic microorganisms rather than the anaerobic that are most likely to introduce pathogens in your plants

  2. to avoid the tea being smelly just add raw,brown sugar to it.that is how i did it since i live in a residential area, i just have about 3k sq feet of gardening space.

  3. Can I also use this for baby palm trees that I have grown from seed or will it be too strong?

  4. Can you use the same technique with grass cuttings and 'feed' it back onto the lawn does anyone know please?
