I am growing it bec. it is an "extractor" plant- its deep taproot brings up nutrients from deep in soil.
I read that the leaves can be composted.
I would like to know if one year of growth is sufficient to bring up the nutrients - or perhaps I should wait another year to compost the leaves.
I have cut the leaves from last year's growth -
if I compost them - I should chop them? since they are dried, can I use them now, or should I wait til they decompose further?

You can compost the leaves of a one year old plant, I would snip off the outer leaves so that you do not inadvertently damage the growing center which will allow you to make multiple harvests of leaves.
compost in common manner(s) Hot compost or cold compost, cold compost will yield retention of more of the nutrients listed below (I would recommend composting these leaves by themselves, then add the resultant material to other compost prior to application)
This is a list of the chemicals and the quantity found in leaves. I have left out those which occur in negligible trace amounts (<10ppm)
I also left out chemicals and compounds found in other parts of Verbascum thapsus L.
I knew they had a lot of good stuff but did not what.
Appreciate this.
impressive.

How do I know when they are ready to be used as compost?
will they crumple? Now I have some that I cut off last fall, and they are dry but still in big pieces.
I can cut them into smaller.
and I have 2 more whose leaves I will cut off.
I'm not sure when I can add them to the earth as compost.
thanks.
any yes I plan to compost them separately, and use them separately, so I can note the effect.

You can compost them green or dried, another way to use these leaves is to dry them then grind them and just sprinkle the powder like it was bone meal.
We are going to use this method for the squashes and tomatoes this year. I have somewhere around 17 plants that are 7 years old, every year they get bigger and I get more leaves from them.
I have, in the past, composted them in coffee cans. This method requires both dried and green leaves (for the heat up) chop coarsely and fill the container, pop on lid.
treat it like a tumbler composter. My last batch took about 3 weeks. You can also add in some spent coffee grounds in the middle along with the green leaves.
This way your browns (dried mullein leaves) and green leaves get a little nitrogen boost to kick start the heat up.
wow this is really cool information! I have been reading about a plant grown in india that accumulates aluminum and is used as a mordant for natualr dye. now I wonder if mullein could be used in the same way?

It is quite possible to use mullein for dye mordant purposes, it has a fair amount of mucilage which from my understanding should work well for mordant purposes.

I will certainly be trying it at some point! thanks for the info.

Bryant, you have seven year old mullein plants? I understood them to be a biennial. We had one two years ago. It flowered last year and is gone this year - but we also have new plants showing up all over our property that were not there when the first one appeared
That high concentration of aluminum makes me think twice about using them in my mulch or compost process though...
The mullein we have continue with green leaves, persisting over the winters, it shocked me that these things did that.
I too thought they would die off and new ones come up in spring.
We do have a bunch of new mullein plants sprouting now but the older ones are still there, it's a curiosity plant to me at this point.
I even thought I had misidentified these as mullein, but they were confirmed as mullein by our forestry department.
I don't compost mullein in my regular compost heaps.
I compost it separately and I am using this stuff as a powder, in the experimental way, on a few control plants.
Until I have enough data, showing benefits, it won't be used in any other way.
It is possible that this material could be good for things like blueberries since the aluminum can form salts in the soil, this is one of those time will tell the whole story items.
Bryant, have your seven-year-old Mullein plants ever put up their central flower spikes?
I'm asking because I currently have a three-year-old Mullein that hasn't flowered yet. Early last spring I transplanted a 2nd-year plant that was about to be destroyed by a mower. In transplanting it I broke most of its roots, and the place I put it was a hard compacted dry path spot. We then had a ton of drought, and the plant just sat there all season, not growing much but not dying either.
This year it's growing vigorously, and I'm assuming it will put up its spike. But the lesson I took from this is that a supposedly biennial Mullein will last longer if it doesn't get a chance to flower in year two. This makes me wonder if a plant could be maintained indefinitely by nipping its flower spike every time it tries to throw one up.
2 of my 3 mullein appear not to have come back after the winter. True it was a bestial winter, but I'm surprised as I think they are hardy plants.
Last year was the first year that I grew them from seed.
Perhaps they will still show up, but I think not.
We call it 'Indian slipper' around here. I agree with redhawk. Don't compost it, way too many medical benifits, anti-inflammatory, anti-bacterial, digestive health, the small flowers are a pain reducing sedative similar to, asprin, soothing to the skin, and eases joint pain.
