Title: Comfrey types and facts ..
Post by: surfivor on May 10, 2014, 08:47:48 AM

 The FDA claims eating comfrey can be dangerous to the liver due to alkaloids, however I heard in actuality the amount of alkaloids they injected into rats to figure that out you would have to eat a whole field of comfrey to get the same effect for a human (about 5,600 leaves), nevertheless FDA discourages internal use of comfrey though it has been used as a medicine for thousands of years

 I guess the comfrey that many people grow is sterile so you get no seeds and it won't spread. You have to spread it by root cuttings. I saw comfrey seeds online, but those must be for the non sterile type which one web site says just use the sterile type ..

Buying the pieces of root is very inexpensive. I bought both the smallest size crown division and also root cuttings from Coes Comfrey. Both were great. I started the root cuttings inside in a flat, then I am about to transplant out. I dont want the ones from seeds as then the spread could become uncontrolled and invasive. I also want this strain which is more palatible to livestock

I've tried seeds several times without any luck, but now just use sterile blocking 14. If I want more now I just dig it up in the spring and take the root and plant it somewhere in my garden. There's always enough root left where the original plant was growing so it will grow back.

I don't use it medicinally. I use it to make a compost tea with the rotting leaves. One plant harvested into 15 gallons of water makes a stinky, but nutrient rich liquid fertilizer in about a week during the heat of the summer. During the early spring it takes a bit longer due to the cooler temperatures. You can harvest each plant about every six weeks where I live.

Different species of comfrey contain differing levels of pyrrolizidine alkaloids.

As one article states (http://www.kerrysherbals.com/articles/comfrey_safety.shtml):

Another problem with the studies which were done on comfrey is that the researchers often did not differentiate between the different species of comfrey. Russian comfrey (Symphytum x uplandicum) contains up to 5 times the amount of PAs as common comfrey (Symphytum officinale). However, in one study, the names S. x uplandicum and S. officinale were used interchangeably. In addition, the root contains a much higher level of PAs, as many as 10-20 times the amount found in mature leaves.

Bocking 4 and Bocking 14 reproduce from the root only.  Bocking 4 is all-purpose, Bocking 14 may be bitter to livestock, handy if you don't want your chickens to pulverized it.

I have used Coe's Comfrey and can wholeheartedly recommend them.

I've got Bocking 14 from a local guy who I met on the Permies forum, he gave me a small piece of root cuttings and over 2 years that has grown into about a dozen plants that I still have plus I've given away another 12-16 crowns...I can confirm that it's sterile as the seeds don't work and my chickens wouldn't touch it... As Jack as mentioned about spiders they like it as well as ground nesting birds, I've found several under the leaves so I always need to check before I dig or cut it back.

I found they are hard to kill, I didn't plant the root cutting for several weeks as I forgot about them in a paperbag, it looked liked they dried out and I planted them anyway...after about 2 months they started to pop up

Good stuff guys.  Indeed the roots have a lot more PAs than the plants. I am growing mostly bocking 4 myself right now but do plan to grow some native stuff from seed.  While I think even the bocking 4 and 14 leaf is moderate enough in PAs for safe use, there is no substitute for the orginal that has been used (as in we know from literature) since 300 BC might I add safely.

Coe's Comfrey (http://www.coescomfrey.com/comfrey.html)

I have mostly bocking 14 from Horizon Herbs, but I also have some Coe's number 4.  Both do well with my harsh winters, but I have fairly mild summers and it is on the thirsty side when it's hot.
Title: Re: Comfrey types and facts ..
Post by: mountainmoma on May 14, 2014, 01:41:36 PM
Comfrey prefers water, but it will survive if you cant get to it, once it has enough root base. There was a piece of root I planted and forgot about until I saw it come up the next year -- but that wasnt full sun. Hm, there is another one forgot about, grown over by blackberries for a few years, blackberries aggressively taken out by workers, with no thought there might be anything there to save. A pile of wood chips dumped. Then, the next year like a phoenix rising form the ashes, comes that comfrey plant.

It does not rain here for 6 months of the year, sometimes longer like last year.... But, if you want to get multiple cuttings, and nice large growth, water it.

This is why I dont have the spread by self seeding type. ANd, this is why they say to think hard about where you plant your comfrey as it will always be there.

Actually one thing kills comfrey, grass.  If you let grass run amuck in an area it will eventually kill comfrey.

Comfrey is hardy to at least USDA zone 4, all varieties it doesn't matter.  Heavily mulched with some heat trapping I bet well into zone 3 would not shake it.  It can regrow from a piece of root the size of a pencil eraser.  Don't sweat it at all, just plant what you want and it will grow.

I orderd some root cuttings from bocking #14.

Since I plan to move I am not planting it outside but plan on growing it in a pot for easier transport, etc.

How long from planting say next week will it take to grow the full plant?

Also how long before I can start using it for root cuttings?

thanks!

The stuff here was started from large cuttings and was in the pots from 6-9 months depending on the pot.  Use large and DEEP pots for best results.  Mine we plenty big, but not as deep as what would be optimum but worked fine as you will see https://www.youtube.com/watch?v=9p0ndfxFrqo

Comfrey is a "mining" plant, it's roots go deep to pull minerals out of deep soil.  If your comfrey container has drain holes in the bottom, the roots will eventually travel through those holes to reach soil beneath.

You may see comfrey reappear when the pot is later moved.  Just sayin'.

Awesome Jack! Thanks for the link to the videos.

I have a large planter that Im going to grow it in for the next 6 months to a year.  Hopefully I can get the word on a new position and moved by then and next summer harvest the root cuttings and crowns from this one and get a good crop going (taking your PDC this summer so It will be incorporated into the new properties design).  Then I am planning on selling these to local and national buyers, small scale, but enough to say pay for a few boxes or more of ammo (or maybe a dinner for the wife)

Finally got my root cutting today and actually looks more like a crown than cutting!


I was wondering should I mix in some manure for it and later some worm castings/juice?   

I know it lose nitrogen so I thought manure would be good.  The stuff I have is older so not fresh fresh.

As long as it gets water, it will thrive regardless of the soil you put it in.  I wouldn't waste the time, energy or effort.

Post by: R_Morgan on May 31, 2014, 02:35:55 PM
Wasnt any time or effort the stable is full of it a few yards from the house, threw in 4 or so soaked handfuls into the soil and hand mixed it in some straw for mulching right below the soil surface and watered it well.  Stuck the root  2 inches under the surface and placed it in the sun room where it will get partial to little direct sunlight.

After I harvest some roots next spring and summer, going to start selling this locally, maybe even over the net if they dont pass that stupid net tax and make it a huge pain in the butt to sell online.  The more that sell it the better it will be for everyone, more competitive market.  Will be grown in without any artificial fertilizers, etc., organic soils/manure and worm juice.

 This is where I got my comfrey:
http://www.ebay.com/itm/111108395866?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

How can I tell if it is the sterile kind or if it will produce seeds and spread ?
It looks like it may be getting ready to flower in a while, does that mean anything ? I did not know that there was a big difference when I purchased it and when I did hear about it I looked at the site and assumed it was sterile, but now I am no longer sure.

Ebay might not be the best place to buy comfrey.  The page doesn't indicate if it is a Bocking variety, or if so, which one.  It's good practice to ask before buying.  Let's assume this is wild comfrey and the seeds will make it invasive.  If you do not want comfrey everywhere, simply keep the flowers trimmed off.  Then it can only propagate by root.

I believe all varieties of comfrey will flower, it's some of the hybrid varieties that make sterile seeds.

Title: Re: Comfrey types and facts ..
Post by: surfivor on June 01, 2014, 02:13:15 AM
If it's sterile it won't produce any seeds I guess or will it produce sterile seeds ? I would guess perhaps the former

 I sent the seller a question on ebay:

" I bought comfrey from you last year as someone online had mentioned your product. I have since learned that some comfrey is sterile and will not spread through seeds. This type of comfrey is recommended by many as if it is not sterile then it will spread and is fairly invasive. Since I did not know about this previously, whichever type it is is no fault of yours but can you tell me which type it is as well as if it is bocking 4 or bocking 14 or what type ? Is it sterile or not ? I would just like to know so I can plan accordingly

Thank you kindly"

Post by: Kreindl on June 02, 2014, 01:23:42 PM
I'm hoping this is a type of comfrey and now that it has flowered I think it is true comfrey (Symphytum officinalis).  It is all over my new homestead which tells me it propagates via seed unlike the Russian Bocking varieties.  I have some of the Bocking varieties which have larger leaves.  Above someone mentions wanting to sell comfrey and having both types available for sale sounds like the best route to go.  I could see selling roots of both types and seeds of the true type.

  I wonder if they two types can mix to produce a hybrid variety with seeds that grow.

With flowers, which the bees like. Now that I've viewed the flowers I think it actually is a type of comfrey.

I ordered from http://www.nantahala-farm.com/comfrey-growing2-s.shtml (http://www.nantahala-farm.com/comfrey-growing2-s.shtml)  it took about a week to get here and the cutting was large, a ball of root, but not a cutting about the size of a tennis ball.

I bought Bocking #14 and it was planted on saturday and is just about to break through the soil (should be peeking its head out tomorrow or the next day).

They are a little pricier than others, $5 a root cutting (but it was large) and $7 flat for shipping no matter how many you order, so its more cost effective to order more than one if you are so inclined. 

However like i said i HAD it in hand in a week vs 2-3 for coes.

 I am confused a little because I see lots of articles on comfrey saying it has more nitrogen than barnyard manure. I see other articles saying it gets it's nitrogen from the soil. Aren't many soils lacking in nitrogen ? Does it get nitrogen from deep in the ground ? It doesn't fix nitrogen ? Something doesn't add up ?

 This web site says the comfrey the guy planted stole all the nitrogen from the soil and deprived a nectarine tree of nitrogen (3rd picture down):

http://www.waldeneffect.org/blog/Growing_nitrogen_in_the_forest_garden/

Other web sites may imply comfrey fixes nitrogen, but jack never mentioned that it worked that way
Title: Re: Comfrey types and facts ..
Post by: endurance on July 04, 2014, 06:16:09 PM
My understanding is that comfrey, like all other fast-growing green leafy plants, consumes a lot of nitrogen, potassium and and phosphorus.  That's why it's not recommended to be directly in your beds, but rather, around your beds and used to make a liquid compost for other plants.  I haven't heard any experts claim it fixes nitrogen.  It's a bioaccumulator-it pulls lots of stuff out of the ground, but until you kill it, it doesn't release them.

Having learned some of this along the way, I have some plants in the absolute wrong places.  Some I've put effort toward trying to kill them, others I just make sure everything around them is getting plenty of liquid fertilizer.

I bought some potted comfrey from Horizon, they were pretty quick. I ordered true comfrey and moved them into larger pots. Since then there are what looks like comfrey seedlings growing, but I am not sure about that yet. 4 of the 6 plants have grown quite a bit. I mixed some fast draining soil and try to keep them damp, the soil drains quick if it gets too wet. I did try making tea with a comfrey leaf and it had a nice mild flavor. I wouldn't drink it every day, maybe once a week. I just dropped a leaf in boiling water and let it steep in a thermos a couple hours before drinking. I do the same with a few other herbs.

Just a quick update on my comfrey progress.  It has been around 6 months my bocking #14 has been in a pot and thriving. I have cut it repeatedly and it is still sending up new leaves.  I had it outside until the cold took its toll but brough it to the basement before the freeze. I had thought about planting it for the winter and digging it back up, but its a rental property so I'm not going to do that. I put it in the basement where little light gets in and the dang thing is coming back to life!    I checked and the roots are looking great. Will probably wait until after the first of the year and harvest some roots to start 10-15 others for use on the property we are looking to buy sometime next summer.  Potting isn't great, its not as healthy or growing as high as it would be wild but for the time being its doing well and will serve its purpose as a grandfather/mother to many hundreds to go on the property eventually

I've got around 100+ plants growing, about 30 that are 3 years plus of age. I got both bocking 4 & 14. With the 14 being the older ones. I transplanted all them after we sold our old place, knowing that there would still be some left in the ground that would pop up fore the new owners. I'm really happy with Comfrey and plan on using it for animal feed, fertilizer and tea.

I'm also trying this morning a experiment; I had dehydrated some leaves about a month ago, then ran tht through a food processor for making a small leaf blend for adding to foods, making tea etc. Last night I noticed that I had a huge canker sore inside my bottom lip...probably from too much sweets already this holiday season. In my reading about Comfrey there has been several studies done on stomach ulcers etc, so I figured I would put some of the dried Comfrey on it and see what happens. Will let you know

Maybe, maybe not, I has a very deep tap roots and won't  give up easily.  If you decide to get rid of it I would dig down first and get most of the roots.  Then cover with multiple layers of cardboard and mulch.  It will easily return and then I would repeat and remove cardboard and dig down again and remove at much again and cover with cardboard  and repeat as necessary. Hope you don't have too to remove, could be a lot work. jeff

What about landscaping cloth or a plastic tarp for a year?   Can comfrey "walk" out from underneath a 4'x4' sheet of impermeable material?

I don't ever see myself trying to remove the comfrey, but I like to brainstorm ideas.

If you really want to kill it, get a couple of ducks.  I was told by various people that comfrey, once well established, was virtually indestructible.  But then my ducks discovered the stuff.   
Before I knew it, the ducks had stripped the comfrey patches bare...right down to the earth. I immediately fenced the areas off away from them and hoped for the best, but alas, they had managed to do the impossible as a year later not so much as a single leaf reappeared.  So this fall I ordered and planted out approx two dozen rootings/cuttings of Bocking 4, Bocking 14, and True/Common comfrey in an attempt to re-establish my comfrey patches. No ducks allowed!

With the deep tap root on comfrey I'd be very concerned with the roots getting into your leach pipes and clogging them. That would be an incredibly expensive experiment if it went wrong. The rule I've heard is to never plant anything with a root system deeper than three feet over a leach field.

I have some true comfrey that is now flowering. Some of the flowers have been falling off leaving a cup like piece behind. Inside the cup there appears to be long thin things (seeds?) with bristle like hairs at the top, sort of like marigold seeds. Does anyone know if these are comfrey seeds? The plants are now indoors so there's no danger of it spreading wild, but if they are seeds I would like to try growing some when it gets warmer.

Wow, look at how far this BS can go with stuff like comfrey, found this:

"It is illegal in New Zealand to grow Comfrey in your garden.  You cannot buy fresh Comfrey anywhere, and I think that even the herbal comfrey pills have been taken off the market."

I had 1 true comfrey plant I got from horizonherbs.com that was in a pot and left outside all winter. After a month or so where I gave it up for dead  a small leave started growing. Before long the pot was crammed with plants. It never got flowers before it 'died' so seeds did not come into play. My best guess is sections of root that survived the winter grew back into new plants.
I took one of those new plants, put it in a small pot & took it to work. There it gets no sun but I have a cfl grow light that's on about 12 hours per day, and it's always in the upper 60s. It's growing nice and pretty quick.
I did collect some seeds from a different plant that I let get flowers. I still have to plant them and see what happens. I havent tried using a root cutting yet but it seems thats the easiest way to propigate. Has anyone grown a patch of comfrey and later tried using the area to grow other seeds? I know comfrey is hard to get rid of so I am not sure if comfrey can be cut to the ground so the area can be seeded with something else, or if the comfrey would just out compete any new plants.

Last year I planted root cuttings of both bocking 4 and 14 in pots because I was staying with my grandmother at the time.  When I later moved the pots back home I didn't get around to transplanting them to their new home right away.  When I did move the pots, several pieces of root had already grown into the ground.  At the time, I just thought "good, more plants." I never thought to note which variety was where.  So, when these new plants start coming up from the roots, are there any really distinguishing characteristics between the two?  Will chickens only nibble on bocking 4 or will they eat 14 as well?

I only have true comfrey, but I kind of remember you can tell them apart by the leaves, one was more narrow and pointed. Some time back Jack did an episode or two on comfrey where he talked about that, and if I am not mistaken he spread comfrey by using a pot with a drainhole so the roots would get into the ground. Try searching for the comfrey episodes, they had a lot more info than I can remember.

I would say it's not too late to plant roots.  I'm in KY.   Last Sept. I pulled up most of the plants I had in a raised bed and transplanted.  Cut the long pencil thick roots into 1" pieces and planted horizontally.  Replanted the crowns. These were a mix of Bocking 4 and 14.  They did fine. This is in below average soil, I amended with some natural fertilizers.

I replanted the raised bed with herbs and mints this spring and the comfrey that was was left in the bed tried to take over.  It is quite hardy.  NOTE:  I had to spray my berries and trees to get rid of the Japanese Beetles.  Sort of pushed them over to the comfrey.  They REALLY like the comfrey leaves, which I did not spray.  After cutting the comfrey back to stubs on 8/1, they are already growing like "weeds".  Extremely robust plants.

Thanks racer038. I'm hearing nothing but good about comfrey. I think to be safe I will go with both Bocking 4 and 14. True Comfrey seems like a possible problem. I don't think it would be for me but I don't want to inflicted my neighbors.
 
Just up the river from KY btw.
