Seed-saving: Collecting Dry Seed

by Chris McLaughlin

It’s easy to save seeds from plants that produce pods, husks, and other dry casings such as peas, beans, and flowers. The technique is called “dry processing” and is faster than collecting seed from fleshy, pulpy fruits such as tomatoes and cucumbers.  Seeds that are dry-processed can be allowed to dry right on the plants unless there’s wet weather in the forecast.

Gardeners collect these seeds in different ways. Seeds often fall where they may, naturally, little by little. Some gardeners make collecting them easy and as the seeds begin to mature, they secure paper bags over the seed heads and attach them to the stems of the plants. Thus, catching any seeds that ripen early.

Once you have the seed, you’re actually left with a mixture of seeds and what’s called “chaff” as opposed to pure seed. Chaff is pod or husk coverings and other debris that fall in with the seeds.

Separating the seeds from the chaff is a technique called “threshing.” Threshing is used to remove the coverings from the seeds. Commercial threshing is done by multitasking machines that can harvest, thresh, and winnow the seeds all at once. For the home gardener, a bag, pillowcase, or small sack is all that’s necessary.

Simply put the collected seeds into the bag, secure the ends, and roll it around, lightly crushing the contents a bit. Don’t get all macho on me and break out a hammer for this — you don’t want to damage the seeds. For the tinier ones, there’s nothing wrong with using a flat board to gently press on the seeds to loosen the chaff.
The next step of dry harvesting is called “winnowing.” Winnowing is just a five-dollar word for getting the loosened chaff off of your seeds before you store them. In nature, this would be taken care of by the wind, but you can use the same idea by placing the seeds into a bowl and shaking the bowl around a bit. Most of the chaff is lighter than the seeds and it’ll rise to the top.

Be sure to have a large sheet underneath your workspace so if any seeds are blown away with the debris, you can retrieve them. Work outdoors only on a day without wind. Now, blow gently into the seeds to remove the lighter-weight chaff. Repeat this process until all (or most) of the chaff is gone.

Be sure all wayward seeds are removed from the sheet underneath before you do any winnowing with other varieties. Another option is to use a screen or sifter where the holes are smaller than the chaff to simply sift them apart. The size of the sifter holes will depend on the size of the seeds and the chaff.

Label the seeds with their name and the date they were collected immediately after you’ve finished dry harvesting each variety. Excellent record-keeping is your best friend when it comes to seed-saving. It’s amazing how easy it is to mix up seed varieties!

 

First There Were Wildflowers

by Sandy Swegel

Cecilia posted a question on our Facebook page this week asking if we knew a website like ours for wildflowers.  Wait, I thought that’s us.  We’ve gotten very enamored of vegetables lately but we know our roots:  we started as a wildflower seed company.  BBB Seed’s name came from our original name, “Beauty Beyond Belief” which means the beauty of natural wildflowers that can be in your garden all year round.  Later BBB Seed also stood for Bounty Beyond Belief (heirloom vegetables!).  Once we added the great line of botanical products, it meant Botanicals Beyond Belief.  And I can imagine a time in the future, no doubt accompanied by a few margaritas after work when we’ll come up with some more BBB’s.

But wildflowers were our first love…and if you see the photos of our head honcho Mike’s house, you’ll see a wild meadow of wildflowers.

Wildflowers are really easy to grow.  There is an entire procedure you can follow to properly install a wildflower area:  kill all weeds first, spread seed in Fall or late winter and let spring rains gently bring them to life.  But sometimes life is busy and you don’t have time to do things properly.  I’m waiting with eager anticipation to see what happens with the package of Butterfly and Birds mix I gave my neighbor Dana.  She has over an acre of property and she’s in retirement, so can’t spend too much work in any one spot in her garden. But she loves wildflowers.  Last weekend I saw her with her hoe, scratching a six-inch path of bare soil along the entire length of her property.  She was removing grasses and weeds.  Then she sprinkled the seed mix the entire path of her narrow trough.  She followed with the hose watering everything in.  I heard her explaining to the seeds that she didn’t have a lot of time to make a fuss over them, but she’d make sure they got lots of water to germinate and grow and that she couldn’t wait until they made a beautiful fence of wildflowers along the edge of her property.

I think she’s going to be right.  A wildflower garden shouldn’t take more than that.  The consistent watering until the plants are established is important.  And weeds and grass will grow (and she’ll probably cut down the thistles that come up), but I’m pretty sure the wildflowers will prevail and make a natural fence of color and beauty for the butterflies and birds and especially for the people.
