One excellent way to become more self-reliant about improving soil fertility is to grow comfrey. Comfrey is a perennial herb, related to borage, also known as knit-bone or boneset…also known as a terrible weed. Amazing how terrible weeds like dandelion, nettle, comfrey, are actually so terribly good at taking care of our needs. Comfrey’s taproot plumbs the depths of the earth, bringing up more minerals and well-balanced goodness than a hen can poop. Certainly more than chemist could mix.
When I have plenty of comfrey, I shall plant it around my fruit trees to pull up nutrition from deep in the soil; then cut back the leaves from time to time (say, when they’re a couple of feet tall) to mulch the tree. Their broad leaves shade the tree roots, too, thank you.
I’d feed it to my chickens, and the goats too.
I’d make a comfrey tea to feed to other plants, as you would with nettle – simply cover with water, or not, put a lid on it, and allow to decompose til liquid. Then dilute to use. Smelly yet effective.
If anyone in my family shatters a bone again, boneset makes an excellent poultice.
Now, I’d like to have plenty of comfrey plants, but one must tread the line carefully. Common comfrey will self-seed until there’s nothing in your garden but its offspring, and once established, that root is determined to stay. On the other hand, Bocking 14 doesn’t self-seed very well, so it stays put – then if you want more comfrey, there’s nothing to do but dig it up and divide it.
Luckily, that’s easy. Have a look.
To propagate comfrey, dig up a healthy plant over a year old. Pull apart and even cut your root pieces, plant them just below the surface of the soil, and keep them watered. At the lakehouse, some creature regarded this as a root vegetable buffet, so it may be worth laying an old screen on top for a bit if you’ve got voracious squirrels or other root thieves lurking.
Then let everyone thrive on your useful weeds.
