Thank you Michael for a detailed article with helpful photos. I will give this method a try as soon as mine are dry enough. I harvested most of my seed today. I think there are four more that need harvesting, but they are not mature yet.

Michael, very good article. Thanks for taking the time to provide such detailed pictures and explanation. I believe that even I could follow those directions.

This is a good ideas! Thanks.

Thank you for the acorns, Lynn and Judith!
At first I tried to remove every single piece of debris with my tweezers or fingertips...but I'm not patient enough for this method - the way described in my article is much faster - not as accurate I admit, but the result should be suitable for sowing. I saw, that when cleaning up larger stalks or quantities of seed heads it's better to do it in 2 or 3 portions - takes longer, but gives you a better cleaning result - alternatively you could use a bigger sheet of white paper, but then transfer to the baking paper squares is more difficult...
Just give it a try and let me know if it works for you....

I will soon be doing that process Michael, as I think my seed stalks are almost dry enough. I will let you know how it works for me.

Great idea there Michael I will be sifting my seeds very soon and will give this a try .
