when to harvest comfrey seeds

I have true comfrey and I see the seeds coming in, they are still green. Any specifics on when the best time is to harvest them? I know they are black from when I got some to try to grow from seed.

Hi, new-ish-bie here. I have only been lurking for quite some time.

I have one little true comfrey plant I grew from a seed. It is now in the ground in Hot Phoenix, in mostly shade. It does need regular deep watering.

I also have some of the cultivar (which one I cannot remember) grown from roots. If they don't get water several times a day they wilt. Even with very deep watering, they still wilt badly. They are also in shade! I have read that they have very deep roots, so it seems with deep watering they would do better. They are in their second summer and it doesn't look like they are ever going to amount to much.

The biggest reason I planted comfrey was to feed the chickens their high nutrients. They chickens don't like them due to the fuzzy leaves! I hope they will like the true comfrey.


After you-all harvest your seeds, I would love to buy some from you. ernie 85017 at cox dot net.

I am jealous of those of you who live in parts of the US that has actual soil, not the caliche I have here. Composting, mulching, etc, is slowly improving the soil. Very slowly.

Dont . just transplant the roots in spring or fall seeds will need much more care and you will most likely fail. You could cut the plants right down and divide the roots now but they will need lots of water dayly.

Thanks!
The roots I find on line are the cultivars and I want to stick with the true comfrey. I thought it could only grow by seed. No?
If so, does anyone want to sell some true comfrey roots?

I found that out the hard way, tried to sprout 30 from seed and all of them failed. maybe I will just harvest them and put them in a spot and mark it. If they take off they take off and ill know, otherwise no time spent trying to sprout such a difficult seed.

I just got the roots in this year and they are all coming up. When is the best time to divide them? I don't want to ruin them by splitting them into too small of pieces.

Ernie, I got my roots from horizon herbs, $5 each I believe for true comfrey, they were hardy big fat roots. and all took off and grew nicely.
