6 Easy Steps to Saving Pumpkin Seeds

Not everyone is ready for fall, but for many gardeners, it’s officially pumpkin harvest season! Native Americans were the first people to save pumpkins seeds. They domesticated them over 9,000 years ago! They created the sweet, large pumpkins we’re familiar with today through their years of breeding and selection. 

Saving seed from your pumpkins is a great place to start if you’re new to seed saving or want to involve the kids. Their large seeds make them easy to work with. 

  1. Select a pumpkin.


    Pumpkins, winter squash, and other members of the cucurbit family cross readily. If the pumpkin was grown near other cucurbits, you might end up with fruits that look and taste entirely different next year! 

    This may be a fun experiment if you’re just interested in growing pumpkins for decor. However, if you’re growing pumpkins for eating like Winter Luxury, you may want to ensure that they weren’t crossed. Cucurbit crosses sometimes end up being bitter or even non-edible. 

    Check out our growing guide for more information on isolation.

    You also want to select a pumpkin that is fully ripe so that the seeds are fully mature. The pumpkin should have firm skin, and the vines should be dying back when you harvest.

  2. Scoop out the seeds.


    Slice your pumpkin in whatever was you’re planning to use it, whether that be for a jack o’ lantern or in halves or quarters for baking. Then scoop out the seeds. A large metal spoon can be helpful for this.

  3. Clean them. 


    Clean the seeds as best you can. Separate and compost any fleshy parts clinging to the seeds. Then give them a good rinse in a colander.
     
  4. Ferment them.


    Several types of seeds should be fermented before drying and storage. These include tomatoes, cucumbers, summer and winter squashes, and pumpkins. Some people think that this step is unnecessary; however, we recommend it for a couple of reasons. 

    Fermentation removes any bits of flesh you may have missed as well as the slimy coating on seeds. This will ensure better germination. Second, fermenting the seeds kills and soil-borne diseases or fungus that may be on them. This will help keep your garden and the gardens of anyone you share seeds with healthy.

    Place your pumpkin seeds in a jar and cover them with clean water. Cover loosely with a lid or just a towel. Make sure air can escape. Let them sit for 3 to 4 days, stirring them once a day. Add a bit more water if it begins to dry out.

    It’s okay if the mixture smells bad or you notice some mold growing on top. After three days, add more water and stir the mixture again. The viable seeds will sink while the pulp and bad seeds will float, and you can pour them off the top. Drain and rinse your viable seeds.

  5. Dry them.


    Lay the seeds on a towel to dry. Let them dry until they’re completely dry. This may take 5 to 7 days. If you store them before they’re fully dry they’ll mold and rot.

  6. Store them. 


    Store seeds in an airtight container in a cool dark place. Pumpkin seeds will remain viable for four years or more under the right conditions.

10 Weird, Fun Historical Flower Facts

Flowers bring so much life and joy to our gardens. Many flower varieties have interesting and somewhat surprising histories. From revered medicinals to religious symbols, flowers have played a role in different cultures throughout the centuries. Here are a few of the unique ways people used flowers historically.

  1. Delphiniums are named after dolphins.

    Larkspurs or Delphiniums are a colorful favorite for cottage-style gardens. The name Delphinium originated with the ancient Greeks. It’s derived from the Greek word “Delphis,” which means dolphin. The Greeks thought that the flower bud resembled the shape of a dolphin’s nose. Do you see it?
  1. German Chamomile has been revered by many cultures.

    One of the few medicinal herbs still in everyday use, German Chamomile has been used and revered for centuries. We love it for its soothing, anti-inflammatory effects. The Egyptians dedicated it to their sun god, Ra. In Slovakia, you were supposed to bow to the plant when you came across it, and the Saxons believed it was one of the nine sacred herbs. 

  2. Morning Glories were once used in divination rituals.

     First cultivated by the Aztecs, Morning Glories were used for divination rituals. They made a preparation from the seeds, which contain d-lysergic acid amide, or LSA, which has similar effects to LSD. The seeds were ground and then filtered with water which was drunk to produce visions. They are still part of some shamans’ practices today.

    They also used it medicinally, and healers would take the brew to determine the cause of an illness. The seeds were ground into a paste with tobacco leaves and rubbed on affected body parts to treat pain.

  3. Hollyhocks signified outhouses.

    Now characteristic of quaint, cottage gardens these tall, long-blooming flowers once symbolized something different, outhouses. People planted hollyhocks to screen the view of outhouses while also signifying to guests where they were. The phrase “visit the hollyhocks” was a polite way of letting others know you needed to use the outhouse. 

  4. Petunias used to be lanky with small flowers that were either white and purple.

    Most of our modern Petunia varieties come from two species, Petunia axillaris and Petunia violacea that are native to South America. Breeders worldwide worked through the late 1800s and 1900s to breed larger, double, and more colorful flowers that bloomed for longer periods. In 1953 PanAmerican Seed introduced the first truly red petunia, a multiflora called ‘Comanche.’ The first yellow petunia was bred by Claude Hope and introduced in 1977 by Goldsmith Seeds. These and many other introductions have created all the petunias we know today.

  5. Job’s Tears were used to make beer in 3000 BC.

    Today we mainly grow Job’s Tears as an ornamental. They’re gorgeous in the flower garden, and their seeds make lovely, natural beads. Archeologists found their residue along with barley and other plants on pottery found at a Neolithic site in north-central China, indicating they were used to brew beer. 

  6. Marigolds were used to treat hiccups.

    The Aztecs cultivated marigolds for medicinal purposes and bred them for larger blooms. The De La Crus-Badiano Aztec Herbal of 1552 recorded that the Aztecs used marigolds for hiccups, being struck by lightning, or “for one who wishes to cross a river or water safely.”
  1. Bachelor’s Buttons were found in King Tutankhamen’s tomb.

    Archeologists found intact wreaths of Bachelor’s Buttons in the boy king King Tutankhamen’s tomb, including a wreath of Bachelor’s Buttons, olive leaves, and water lily petals around his head.

  2. Sunflowers became popular in Russia because their oil wasn’t banned for lent.

    While the Native Americans had been cultivating sunflowers for food, medicine, dye, and oil as far back as 3000 BCE, they weren’t brought to Russia until the turn of the 19th century.

    A diktat issued by the Russian Orthodox Church in the 18th century banned the consumption of foods made from various oils and fats during Lent. The list of banned foods omitted sunflower oil resulting in a boom of sunflower cultivation and the eventual breeding of the popular variety, ‘Mammoth Russian.’

  3. Zinnias used to be considered hard on the eyes.

    The Aztecs referred to zinnias as an eyesore. The Spanish agreed, calling them “mal de ojos” or evil eyes. At the time, zinnias were small with scraggly foliage and muddy orange or yellow flowers. Despite attempts by companies to sell seeds in the U.S. and Europe, they didn’t become a popular garden flower until the 1880s, when French horticulturists began experimenting with breeding zinnias.

Flowers have played important roles throughout history. These are just 10 of the unique ways they’ve been used. Have you heard any of these unusual flower facts?

6 Easy Steps to Save Seed Potatoes

If you’re starting to save some of your own seed this year, you might want to give potatoes a try! While they do take a bit of storage space, they’re pretty easy to save. Saving seed potatoes can also save you a lot of money on next year’s garden, especially if you generally rely on having potatoes shipped to you.

What About Disease?

Many people don’t save seed potatoes because of the fear of disease. Commercial producers almost exclusively rely on USDA-certified seed potatoes. However, on a home scale, you can easily mitigate the risk of diseases. Always rotate your potatoes and other members of the Solanacea or nightshade family (peppers, eggplants, tomatoes, tomatillos, and potatoes). Keep your potatoes well weeded and mulched and grow them in rich, well-draining soil. 

Selecting Seed Potatoes

While you can harvest potatoes early in the season for eating, you should harvest storage seed potatoes should when the plant dies back. The foliage dying back makes the potatoes go into dormancy. This will help them keep longer. Make sure you harvest them before you get any hard frosts.

When selecting individual potatoes to store, you want to focus on selecting healthy potatoes that are free from any signs of disease, blemishes, or bruises.

Note that some varieties store better than others, so if you struggled in the past you might want to try a variety like Yukon Gold that keeps well.

Curing 

Potatoes are one of those staple crops like winter squash that keep better when they’ve been cured. Take your freshly harvested potatoes and gently brush any loose dirt off. Don’t wash them! Lay them on newspaper in a single layer somewhere cool, dark, and well-ventilated for 10 to 14 days.

After your potatoes are cured they’ll have thicker skins, a little less moisture, and be ready to store! 

Proper Storage

Ideally, you should store you potatoes somewhere dark where temperatures remain between 35° and 40°F though they will still keep for several months at temperatures up to 50°F. Warmer temperatures or large fluctuations can cause potatoes to break dormancy and sprout early. 

Before packing your potatoes up, go through them one more time and remove any with damage. Gently rub off any large clumps of dirt you come across. Pack your potatoes in ventilated containers. Bushel baskets, root-storage bins, and perforated cardboard boxes work well for this. Cover your containers with cardboard or newspaper to keep out any light.

Don’t store potatoes with onions and fruit, which give off ethylene gas and can cause potatoes to sprout early.

Check On Your Potatoes

Check on your potatoes every couple of weeks. You want to remove any starting to rot or mold as soon as possible, so it doesn’t spread to the others. 

Get Ready to Plant

In the spring, you can plant any potatoes that have sprouted. It’s okay if they’re a bit wrinkly, but you don’t want to use any that appear to be rotting or unhealthy. To plant, cut potatoes into pieces no smaller than an egg with no fewer than two eyes.
