And when to use it? Yard is now full of them..
best thing for that is to yank em out of the ground, grind or cut them up (taproot included) and then use it as a nitrogen input for a compost pile
OR you can shred them and use it as a soil input in lieu of kelp meal
OR you can do a dandelion ferment... which is stinky... but effective
get a 5 gal bucket, fill halfway, add like 10 whole dandelion plants and let it chill for like 2-3 weeks, then use at around a 10/1 ratio with water
I don't really recommend the dandelion ferment to be honest...
it smells pretty funky, and you use so little of it that it'll be around for like a yr or so..
I really think the advantage to dandelion is using them in the soil
for sure
comfrey is even better, if you get a garden with comfrey, nettles and dandelion?
shit, you are damn near done with all your nutrients
my primary issue with the dandelion ferment is that it doesn't really do anything profound, nothing in specific that ONLY the dandelion can do, so in other words it's MUCH easier/more effective to use other nutrients/inputs/techniques to provide them with nutrients.
at least in my opinion anyways.
