How I use herbs - comfrey

Comfrey (Symphytum officinale) is a hugely useful herb and very easy to grow - in fact it can be too easy and has a reputation of taking over gardens!  Its a herb that I think has a place in every garden.

How to grow Comfrey
Comfrey is propagated by root-division, so all you need is to find someone else who grows comfrey and take a small amount of root and leaves, plant them and you will never be without some comfrey in your garden.  Comfrey dies back in frost, and prefers moist cool conditions, so does not do well here in a hot dry summer.  If you have ideal conditions for comfrey (not frost and not hot) you may have trouble with it spreading like mad, and it can grow rather large, with huge leaves.  You can either plan for this by planting it somewhere appropriate, or you can confine it to a pot.  Comfrey is so useful you might not find its possible to have too much comfrey!

How to use Comfrey 
(Isabell Shippard devotes over seven pages to comfrey in her excellent book "How can I use Herbs in my Daily Life?", so I will just try to summarise the main points here).
  • Comfrey has deep roots and accumulates minerals from the sub-soil, as well as being high in nitrogen.  This makes it useful for compost, mulch and to make a liquid fertiliser brew for the garden.  In a permaculture food forest or swale, comfrey can be used as a self-mulching plant to provide nutrients to other plants.
  • My comfrey plants don't often flower, but the when they do, they provide food for bees and other beneficial insects.
  • Comfrey is high in protein, in fact higher than most grains and legumes, and combined with the nutrient content, makes an excellent animal fodder.  I have had to fence mine, because Bella and the chickens were helping themselves.  If I could get it to grow over a larger area, it would be great for the chickens as an alternative to grain. Bella didn't like it at first, so I had to shred it and hide it in her grain ration, but now she will eat it by the armload if I have any spare.
  • Comfrey is also known as Knitbone, Woundwort, Healherb and All Heal.  It has a reputation for soothing skin, and healing bones, tissue and skin.  It can be applied as a salve, in a tea or a poultice.   
  • Some people also eat comfrey, and really, if its ok for animals, then it should be ok for us too, but do see my cautions below (and note that it has a kind of prickly leaf, so best chopped small!)

Controversial Comfrey
There is a lot of confusion about the safety and legality of comfrey in Australia, so here's the facts.  Comfrey is listed on the "Poisons Standard", which is Australian federal govt legislation that classifies poisons and restricts how they are sold, packaged and labelled. It does seem kind of odd to put a plant on there with all the drugs... but anyway, the point is that sale of Comfrey for therapeutic or cosmetic use must be labelled with "caution", because of some drama back in the 1980s when someone decided that it was poisonous due to alkoloid content.  Many plants contain alkoloids and it really depends how much Comfrey you're planning on eating (google it and decide for yourself, this is also well explained in Isabell's book).  

While the sale of products containing Comfrey for therapeutic use is restricted, you should still be able to buy it to plant in your garden and use it how you want. As you can grow it by dividing, and it spreads quite quickly, if you know someone with comfrey, you can just grab a small section of root from their plant and replant it in your garden. That's how I first got some, I've never had to buy it. 

Do you use Comfrey?  Any tips?  Did I miss anything?

  1. We use comfrey leaves as plant food, roughly chopping the leaves and soaking them inside an old pillowcase in a barrel of water, great on tomatos peppers etc, it does smell though.
    You reminded me that I did bring a comfrey root with me now I just have to think what pot I put it in.

  2. I have fond it is good to smother grass and therefore makes a good border plant. Our cow loves comfrey and I have been dividing ours over and over so now I have a good clump going. But it is still not enough for using as feed and in the garden. I don't think you can have too much comfrey if you have animal and a garden.

  3. Like dawn I use mine to make a tea. I just fill a barrel with it and then top it up with water and leave it for three weeks. I add some of this to their water every other night and things like tomatoes grow like crazy! I'm in the process of planting a massive patch of the stuff - its amazing. Add it to your compost as well or fill a trench with it and plant beans on top. They grow great as it starts to rot down.

  4. Cant say that I have tried comfrey, but thank you for the information. It is amazing how many plants, even weeds can actually be useful in the garden and for health. I read the other day that the humble iceplant that grows like a weed here is actually edible, not that I would consider eating it, but the chooks enjoy it :)

  5. Comfrey 'tea' like weed or compost 'tea' can be a bit stinky (an-aerobic) but if you use a solar or electric airstone (aquarium bubbler) it's as sweet as… It's great stuff is Comfrey! I dug some out of a big pot I had a citrus growing in - the citrus was struggling against the robust Comfrey plant. The Comfrey taproot was at least 2 ft long and haring out of the bin into the ground. So although Comfrey planted with a fruit tree in the garden is a great asset, it's too enthusiastic for a potted fruit tree. The Comfrey root is quite thick and carrotty, a formidable grower. Just chop and drop the Comfrey - use a machete or shears, wear gloves if you're going to handle it, it's quite hairy.

    1. I'm keen to try this, I've got the air stone and everything, just haven't had a chance!

  6. We use it for medicinal purposes. Sprains, bruises, torn ligaments, etc. We heat it in a small amount of water and use a stick blender to make a poultice. Pack it on the affected area and leave it overnight. Works wonders.

    We also make salves out of it. We planted in the garden and now can't get rid of it. It's off in its own little spot now so we don't have to deal with propagation.

    Thanks for the post. I found you on the barn hop.

Chicken tractor guest post

Sign up for my weekly email updates here , you will find out more about chickens, soap and our farmlife, straight to your inbox, never miss a post!  New soap website and shop opening soon.... Tanya from Lovely Greens invited me to write a guest post on chicken tractors for her blog.  I can't believe how many page views I get for chicken tractors, they seem to be a real area of interest and I hope that the information on my blog has helped people.  I find that when I use something everyday, I forget the details that other people may not be aware of, so in this post for Tanya, I tried to just write everything I could think of that I haven't covered in previous posts.  I tried to explain everything we do and why, so that people in other locations and situations can figure out how best to use chicken tractors with their own chickens. The dogs like to hang out behind the chicken tractors and eat chicken poo.  Dogs are gross! If you want to read more about chicken tractor

Getting started with beekeeping: how to harvest honey

While honey is not the only product from a beehive, its the one that most beekeepers are interested in and it usually takes a year or so to let the bees build up numbers and store enough honey before there is enough to harvest.  There are a few different ways to extract honey from frames.  We have a manual turn 2-frame certifugal extractor.  A lot of people with only a few hives will just crush and strain the comb.  This post is about how we've been extracting honey so far (four times now), and there are links at the end to other bloggers who use different methods so you can compare. Choose your frames Effectively the honey is emergency food stores for the bees, so you have to be very careful not to take too much from the hive.  You need to be aware of what is flowering and going to flower next and the climate.  Particularly in areas with cold winters, where the bees cannot forage for some time.  We are lucky to have something flowering most of the year and can take honey

Homekill beef - is it worth it?

We got another steer killed a few weeks ago now, and I weighed all the cuts of meat so that I could work out the approximate value of the meat and compare the cost of raising a steer to the cost of buying all the meat from the butcher.   My article has been published on the Farm Style website , which is a FREE online community for small and hobby farmers to learn everything about farming and country living . If you want to know more, head over the Farm Style to  read the the article  and then come back here for comments and questions.  Do you raise steers?  Is it worth it?  Do you have any questions?
