Hello is this Comfrey ? I've found it on a vacant plot at the lottie.(http://img.photobucket.com/albums/v730/northener/106_0635.jpg)
-
Looks like it- lucky you. You can make great compost or liquid feed from that stuff.
-
I wish I could find a pile like that. I have to wait a year before I can harvest any of mine. :(
-
Go and have a look round in the locale - your'e bound to find some just lying about that no-one is tending :)
I could send you a Bocking 14 but it won't be ready yet either. I have in my garden a very tall (Russian comfrey) I think and it has huge leaves which I just strip off and use in the compost bin and on top of the soil, round plants etc. the bocking though is specially bred to be the best and I got it from the Organic catalogue. Whether it turns out in any way superior to the common or garden ones who knows :)
-
Wardy what colour flowers does the bocking 14 have?
-
Bocking 14 has several advantages over wild comfrey:
It is sterile so doesn't set seed so doesn't spread
It doesn't spread by roots either
The potash content of the leaves is the highest of any comfrey - this was found in trials run by Lawrence Hills at the original HDRA site at Bocking, Essex; it was the 14th hybrid tested, hence Bocking 14
Don't buy it - many folk will give it away.
If anyone wants any root cuttings let me know - they will produce plants from which you can harvest leaves next year - meanwhile use any wild ones you can find, they produce much better (and cheaper) liquid fertiliser than any you can buy

Phil, like i say this stuff is on a unoccupied lottie. I reckon it must be bocking 14 type because it hasn't spread all over. How and when is the best time to take some of the root. In the meantime i'm going to use some of the leaves to make a fertiliser.
-
Yes some propogation tips would be great - I have some but the dog keeps eating it?!
Also how is it best to make liquid manure - I tried last year with a mixture of nettles and comfrey (the bit the dog left) and the resultant black liquid stunk so much I was 'asked' to get rid of it.
I put it in a bucket with some bricks on top and left it for a couple of weeks, is that right?

-
you then have to dilute the resultant black liquid by between 10 and 20 times :)
I don;t know what colour the Bocking 14's have Northerner but then you don't grow it for its flowers ;D
-
Phil just got the stuff you sent me thanks loads, i owe you one (or two)
Cheers

Can comfrey cope with freshish manure or does it have to be well rotted?
-
wardy - you mentioned you put the leaves on top of the soil - I thought you shouldn't put uncomposted stuff on the soil - is comfrey different? I've got a self seeded comfrey plant in my garden and this sounds a great idea.
-
my comfrey which i assume is bocking 14 as i let it flower and it hasn't self seeded anywhere has purpley/blue flowers.
i cut leaves and leave them to wilt slightly then put them direct on the ground around my leeks to prevent rust
-
Phil, any chance of sending me some? I would be eternally grateful
-
Phil, the comfrey cuttings you sent me a while ago are rooting ;D ;D
Yes, I got impatient and dug one up ::)
Thanks again :D
-
Comfrey leaves can be used in loads of ways and using them fresh is just one of them. I covered up my potato leaves up the other night with comfrey leaves as they are cheaper than fleece ;D They act as a plant food and you can event underplant veg and shrubs with them. I have a very large Russian comfrey at home which has enormous leaves. I take them off and use them at the back of the border as fresh compost. You can put them in your compost bin and they do break down very quickly and act as an activator (as do nettles)
So no, (after all that rambling) they don't really need to be composted first. use sparingly though as they are a bit strong ;D

Anybody? ???
-
I don't think you need put manure round your comfrey :)
-
Macca,
If you send me a PM with your address and how many you want I'll send some but if anyone else wants any can we leave it til next year - I'll put an offer on the list then - promise
Comfrey does benefit from muck, it draws some nutrients (mainly potash) from its tap root but it still needs a lot of feed in order to produce the leaves (if you harvest them)

It's growing like a weed round here !! :P

Adrian,
Sorry I missed your request for information earlier
To propogate, in Feb-Mar (this the ideal, it allows the donor plants to be replanted and grow on - you can do it during Spring and Summer, but the donor plant will suffer) take a 2" piece of root (make a straight cut at the top and an angled one at the bottom, so that you don't get muddled later). Stick them in some compost with the straight cut edge level with the surface and they will rapidly produce roots and within a month start to produce leaves. I put 4 (one at each corner) in a 7cm square plastic pot so 5 would go in 9cm round pot.
When they look like little plants, plant out 2' 6" or so apart in well manured ground (that's to give em a good start in life) and don't pick leaves this year. You should get up to three crops from next year. Cut them down to the ground when you see the flower stalks starting. Give em a covering of muck/compost each Autumn or Spring - Then you can lift them and give away root cuttings from 2007.
It's nice to leave the odd flower as they attract bees and Bocking 14 doesn't produce viable seed so it doesn't spread like the common stuff.
Be aware, though, that when you lift plants, bits of root will break off, each of these will produce plants so choose you location carefully, it will be you comfrey plot for life!! - again with Bocking 14, the roots do not spread.
You can (and I recommend) make comfrey liquid without water by just piling the leaves in a suitable container, placing a weight on top and collecting the liquid.
The advantage of this system is that the volume is much less (as it's concentrated) and so is the smell. I have a 5 gallon plastic ex-fruit barrel with lid and tap at the bottom (just like a home-brew beer barrel - but much cheaper). I pile leaves in during the growing season with house brick on top and draw off liquid at bottom. At end of season remove the lumpy bits and refill, the old liquid in the bottom seems to start the production quicker than just dry leaves (which isn't long anyway).
I have seen a small version made from a vertical piece of plastic drain pipe (2'-3' long) with the top part of a plastic bottle firmly fixed to the bottom (use waterproof glue/sticky tape. Remember to screw top back on bottle top (or bottom as it is now). Fix pipe to a vertical surface using pipe brackets (as sold in DIY shops). Insert leaves at top and apply a weight - the version I saw used another plastic bottle that would fit easily inside the pipe, filled with water and with a piece of string attached (to retrieve it as it disappeared into the pipe)
Dilute the liquid to the colour of "weak tea" to make liquid fertiliser and then dilute again if you want it as a foliar feed.
Any more info required?

I've got my Bocking 14's but potted on and not planted out yet. I'm doing that pipe thing to draw off the juice. It's illustrated very well in the HDRA organic encylopaedia the way you described Phil. We were all talking about the other day and it seems that everyone is wanting to grow comfrey these days :)
-
I've just produced a (poor) diagram showing the drainpipe comfrey liquid device - the plot holder next door has one so I'll ytake a piccy this weekend
(http://www.hhdra.org.uk/comfreyliquidsmall.gif)
The pipe can be as long as you like, but remember to make the piece of string just that bit longer (and wrap it round a nail so that it doesn't drop inside the pipe
The top of the bottle at the bottom (if you see what I mean) is the "tap" - be prepared to have your hands covered in sweet smelling comfrey liquid!!! ;D

The picture is worth a 1,000 words...thanks Phil

I don't use any liquid in a comfrey maker- I just have a barrel with a tap and sling the leaves in. I don't have one going at the moment due to having had several barrels stolen, but hope to before long.
-
Ta for the picture Phil. I copied some and took them to a lotty meeting last night so hopefully everyone will have a comfrey tea maker :)
-
it's also a good idea to put some gauze or mesh in, to stop the leaves clogging up the bottom end cap.
-
Phil My lotty mate made a comfrey tea maker yesterday and it is now in service. Instead of using the pop bottle in the top he used a champagne bottle ;D
-
What a great thread!
Anyway, ther is quite a large clump of this stuff on the abandoned lottie next to mine & it is in flower right now.
I know I have to cut it now, but will it be OK to put down as a mulch with its flowers?
Am worried they're going to dry & seed my veggie beds.
-
you could take the flowers off first :)

That's just showing off!! :D
On using comfrey as a mulch, spread it out to dry for while and then chop it up, stems and leaves can root!!!

My comfrey plants (five now!) are in pots as I haven't got room to put them in the ground yet. Will they be ok in 6in pots with a feed of chicken manure occassionally?
I am planning on putting a few in my flower beds (when they are dug). How big will the plants get?

Big, it's a pretty lush grower. Count on the clumps being 3-4 feet across before too long.

:o :o :o
Five plants will fill my entire garden!
-
the uncultivated (but rented >:() lottie next to mine is literally covered in comfrey - there is barely a square inch without it. It is now heading towards mine.....
As no one seems to look after it I think I will go and liberate some of the leaves.
-
Aqui,
The well behaved version (Bocking 14) is usually planted 2' - 2' 6" apart and that forms a solid mass. They will be ok in pots for a while.
The ones that are "heading for" you Justy aren't Bocking 14, it tends to stay where you put it. If you liberate the flowers as well you could slow down its spread by seeds
Phil
-
hmm... I think I'll keep them in their pots for now. Although I do want to have enough comfrey to feed my tomatoes (if they ever grow!) maybe just one in the border? I'll see if I have room when we dig up a bit more of the path.
-
Aqui,
You might get a crop if you plant one in one of teh flower buckets the supermarkets use.
