I have just been given a couple of cuttings and been assured that these will not spread everywhere. Can anyone corroborate? I don't think I'll plant then just yet.
I'm guessing that propagation by cuttings means it doesn't seed - but I'm new to this
As I understand it this version is sterile so will not self seed. It is an excellent plant for adding to the compost heap and its foliage makes the best tomato feed - trialled on Beechgrove against standard commercial products and much to Jim's amazement.
It has attractive flowers that bees love and is good ground cover. Comfrey sin't fussy about soil or light levels. I grow it in full sun and partial shade on fertile alkaline loam. A friend grows it in shade in her woodland garden on a lighter, acidic, sandier soil.
Just dig up any that gets too big and bung it on teh compost..
Thanks obelixx. I mentioned I liked the idea of some comfrey to mulch and was given the cuttings. I am reassured that I am not introducing another hard to control plant so I'll give it a go.
I don't have a compost bin (yet?) so do you think it will it be OK to chop up leaves and put on the garden with bought compost?
I must remember to take cuttings myself when it gets too big. I know it has a long tap root. Is that anything to be concerned about?
Better to get a big bucket with a lid and put the cut foliage in water. You will get a very smelly solution (hence the need for a lid) which you then dilute and water on the plants that need it - flowers and fruiters such as roses, clems, toms etc.
Alternatively, use an old dustbin to store the cut leaves dry until you do get a compost heap or to mix in with your bought compost.
I like the idea of drying the leaves - I have smelled the comfrey/water solution. A bit eye-watering!
