  • Nettle/Comfrey Fertilizer.... confused again

    Dear All,

    Forgive me for carping on about these natural fertilizers again... I believe I've got befuddled.

    I was always of the impression that Nettle tea was high in Nitrogen, and Comfrey tea was high in Potassium.

    So there I was last night eagerly digesting my shiny new copy of GYO - only to find a fascinating article that tells me Nettle tea is NOT high in Nitrogen and that Comfrey tea is better for both N and K (if I remember correctly)

    IF this is the case - is there any point in brewing nettle tea - and having two foul smelling containers one labelled 'N' and the other 'K'

    I understand I'm drifting perilously into the realms of 'gardening geek' here.... but once I know I've got this right - I'll be happy.

    Thanks for your help

    here are the nutrients in each out one of me books:
    Nettles: Ca, Cu, Fe, K
    Compfrey: Ca, Fe, K, Mg
    And suprisingly Dandelion has more than both: Ca, Cu, Fe, K, MG, P
    Hope this is of some use

          Ca - Calcium
          Cu - Copper
          Fe - Iron
          K - Potassium
          Mg - Magnesium
          P - Phosporous

          All vital (trace) elements for plant growth..

          Can't BELIEVE my GCSE Chemistry has FINALLY been usefull!!!

            Thanks JimmerG,
            I didn't do much in the way of science at school so never learnt the codes.
            More philosophy and languages for me
            Sounds like dandelion juice would be good for veg. How strange!

              Having done a bit of reading - I can't see why one can't just chuck everything in one bucket - sure some plants need slightly different trace elements.... but one only has so much time to mix different potions for different plants.

              I reckon I'll stick comfrey and nettle together in the same bucket - I've even read that mares tails can be thrown in too as they're full of good stuff.... must be their 5 foot long roots tapping into deep reserves that other roots cannot reach.

                where did you read about the mare's tail? Our garden is riddled with it It's a constant battle and it gets everywhere!!!!
                If it can be put to some use then I would love to know. At the moment it goes in old growbags and gets disposed of. I don't want that in my compost

                  I've got nettle liquid and dandelion liquid in separate cartons but when I use them I usually mix a slosh of each into the water.

                  I've heard of dandelion being good, but never knew exactly why - thanks, Krazy Krok and Jimmer G
                  - I used mainly flower heads with the odd stalk sticking on and a few leaves.

                  I keep them in large milk cartons (though I've lost the caps) as recommended by Two Sheds on another thread.

                  One thing, the dandelion mix is non-smelly.

                    Incy - I found it here... Liquid plant fertilizer - Green manure protects the garden

                    It talks about fresh/dried marestails (surely they can't be both!) in a bucket of water for one day!! High in Nitrogen apparently - which is handy as I have a blue drum half full of water which I use for 'drowing' maretails and couch grass - had no idea the water would be usefull.
                    There's also mention of a couple of interesting ways of getting rid of the 'open sewer' smell of rotting nettles and comfrey..!

                        Use for mares' tails. Scrunched up they make good pan scrubbers. It's the silica in them. Allegedly!

                          Pan scrubber ......No, not in my vocabulary, pans wash themselves round here ( or maybe OH does while I'm working)

                            Surprised nobody actually mentions nitrogen (N) in their answers, only Jimmer in his question.

                            ___________________________________________

                            Nutritional Value of Bocking 14 Comfrey.

                            L D Hills listed the following in his book Comfrey, Past Present and Future –
                            Comparative Nutritional Analysis of comfrey, compost and manure Material Water
                            % Nitrogen(N)
                            % Phosphorus (P)
                            % Potash (K) %
                            Carbon-Nitrogen Ratio

                            Farm Yard Manure (H2O)76.0 (N)0.64 (P)0.23 (K)0.32 14 - 1

                            I know it's a bit boring but no gardener should forget his/her nitrogen.
                            Why didn't Noah just swat those 2 greenflies?

                            Why are they called apartments when they are all stuck together?

                              JimmerG,a VERY good question.
                              krazy krok,thanks for the explanation,at least I know what's in my pong.
                              Now I'm sure about dandelions(nobody believed me when I said it was good).
                              So,as a result-may I use my nettle pong to water toms and chillies(shortage of comfrey here)?
                              As for mare's tail-you can make some herbal tea-it's good for nails and hair(because of silica)
