Medicinal Herb Seeds Per Gram

Stinging Nettles
Bulk Medicinal Herb Seeds

Granted that careful planting of a small packet of seeds sometimes gives more results than a haphazard planting of a much greater number of the same seeds, yet still, it is nice to have access to larger quantities of seeds. Often labor and materials may be minimized and plant happiness maximized by planting directly in the garden or field, and this requires more seeds than when one uses a more controlled greenhouse technique. Also, those of you planning commercial grows in larger greenhouses need more seed.

When I started making larger lots of seeds available for general distribution, I wanted to provide the kind of service that I needed 30 years ago when I started wholesale planting of medicinal herbs. It was hard to find, for instance, marshmallow seeds, no less top quality certified organic marshmallow seeds in bulk. I am excited to now be able to provide this service! As a seed planter, I find it to be very useful to know both the weight of the seed I’m using as well as the seed count, so have provided this information, which should make it easier to plan your purchase.

In order to assist our seed planting friends, here is a handy reference. These are average seed counts per gram weight that have been compiled over the last 30 years by seedsman/herbalist Richard A (Richo) Cech.
