Thanks for your description of situation is unbelievablly sweet sounding...lots of comfrey!
So that's a loaded questionthat begs to be answered quickly.
So this is my short answer:
Cut the largest leaves off 2" from soil.
Some cover with 2x water and others just cram the leaves into a container/ let sit at least 70F for as long as possible.
When some liquid occurs; pour it off dilute 20 X pour on soil/plants.
Even at that dilution, I won't promise that it can't burn. 20:1 is usually safe.
But as always first time experiments should test with your less than favorite plants.
I personally find stronger dilutions acceptable to most of the plants that I grow.
And of course the worms race to eat it whole!
Feed some fresh leaves to animals.
Chop up some into worm bed and layer in compost pile. It has lots of water already in the leaves.
If you want to drink it just blend some leaves/soak them until the tea is barely opaque/strain to drink. You can add more water for several servings.
I feel using dried leaves are best for making drinking teas; as the water gets real dark real fast.
The trick is to not let it soak too long if you plan to drink it.
Could you speak more on how comfrey aids in calcium uptake? This is a very interesting topic for tomato growers battling Blossom End Root (BER) which stems from the plant's inability to take in much-needed calcium.
Could a COMFREY tea on tomato plants be the answer to staving off BER?
I think COMFREY (or should it be just Comfrey?) sounds delightful. As I am trying to figure out what to plant in my second house - in Florida- I wanted more Comfrey info, like how do I get some, what does it look like, what pests attack it, will it grow all year long in Zone10? Is it an invasive pest plant in (near) South Florida? I think Brazilian pepper is enough of a pest for me, it's all around.
Any information, true, humorous, or false, will be greatly appreciated. Note: please let me know if information is false so I won't spend too much time on it. Thank you.
