Thanksgiving: A celebration of the native plants and indigenous crops that grace the table

Native vs. non-native – that a subject that is brought up frequently on our forums and one we have to discuss at length.  However, I thought I’d take it from a different direction this week, a little diversion if you will, seeing as we are just a week away from our American celebration of Thanksgiving that centers around food – much of it native to the United States.

It is a holiday that is quintessentially American (or North American, since our Canadian friends also have their own Thanksgiving).… Continue reading this article “Thanksgiving: A celebration of the native plants and indigenous crops that grace the table”

Grow Garlic – Keep the Neighborhood Vampires at Bay

While most of those gardening tasks are coming to an end, in most parts of the US it’s time to think about planting a few things in the veggie garden to bring a flavorful bounty next year – garlic (and a few related alliums).

I often reference Halloween and vampires when I talk about garlic, not just because traditional lore says that garlic repels vampires, but because it is a good reminder of when to plant garlic in the garden.… Continue reading this article “Grow Garlic – Keep the Neighborhood Vampires at Bay”

Sex and the Single Squash: A study in plant sex, sexuality, reproduction, and seed saving

In the 1960s, author and future Cosmopolitan magazine Editor Helen Gurley Brown scandalized the country with her book about independent single women called “Sex and the Single Girl.”  Taking a page from Ms. Brown, we can have a discussion about “Sex and the Single Squash.”  Here, we can talk about plant floral structure and reproduction and its effect on fruit production and even seed saving.  A true discussion of the “birds and the bees” if you will.… Continue reading this article “Sex and the Single Squash: A study in plant sex, sexuality, reproduction, and seed saving”

It’s all about location, location, location

Whenever we (the Garden Professors and our community) answer garden questions, we almost always will ask the location of the garden.  I’m sure this frustrates some people who think that plants act the same wherever they are.  However, this is not the case.  There isn’t a one-size-fits-all to most garden questions.

For example, I work on the east side of Nebraska in Omaha, along the Missouri river.  The environment (weather, soil, etc) here is vastly different than where I’ve spent most of my life in West Virginia. … Continue reading this article “It’s all about location, location, location”

Arbor Day of Horrors

Happy Arbor Day!  What, you aren’t celebrating?  As a recent transplant to the state of Nebraska, I was amazed to learn that the Cornhusker State is the birthplace of the day we set aside to celebrate trees.  (Since most people associate the state with corn, football fanatics, and steak).  And since Arbor Day is near and dear to Nebraska, it is the only state that celebrates it as a civic holiday (most state offices were closed – no drivers license for you!).… Continue reading this article “Arbor Day of Horrors”

A Raised Bed Rebuttal: In defense of a common garden practice and soil health

One of the things I miss (and sometimes don’t miss) after my move from West Virginia to Nebraska is writing my weekly garden column for the Charleston Gazette-Mail newspaper.  It was a great way to always keep thinking about new things to talk about and a great way to connect with the public.

After I left, the newspaper replaced me with a team of 4-5 local gardeners who would take turns writing about their different gardening insights and experiences. … Continue reading this article “A Raised Bed Rebuttal: In defense of a common garden practice and soil health”

Starting Seeds with Success: Best Practices

As we edge closer to spring it is time to start getting ready for the active growing season.   Many gardeners kick off their gardening year early with indoor seed starting to prepare for the upcoming season.

Starting your own seeds is an excellent, and often economical way to prepare for your year of gardening. Whether you grow vegetables or flowers (or both), starting from seeds can offer many benefits. Of course, there are some dos and don’ts for getting the most mileage from your seed starting endeavors.… Continue reading this article “Starting Seeds with Success: Best Practices”

Translating the Language of Seed Packets: Hybrid, Heirloom, non-GMO, and more

Hybrid, heirloom, organic, non-GMO, natural….there’s lots of labels on those seed packets or plants you pick up at the garden center or from your favorite catalog.  Since the seed-starting season is upon us, let’s take a minute to look at some of the information – and mis-information – you might find on those seed packets.

For a brief overview, here’s a short video segment I recently shot for the Backyard Farmer Show, a popular public TV offering for Nebraska Extension:

Hybrid vs.… Continue reading this article “Translating the Language of Seed Packets: Hybrid, Heirloom, non-GMO, and more”

Love notes of genetics and physiology for Valentine’s Day

Ahhh….’Tis the time of year when we celebrate romantic love in homage to a 3rd Century priest who came up a head short for performing unsanctioned Christian weddings.  (It is also of note that St. Valentine, or Valentinius as his friends called him, is the patron saint of bee keepers but, strangely, not of birds, flowers, or trees).

In celebration, many suitors, partners, spouses, fling-seekers, and woo-wishers will flock to florists, grocery floral counters, and even gas stations to purchase flowers, namely roses, that have likewise been beheaded.… Continue reading this article “Love notes of genetics and physiology for Valentine’s Day”

Of potatoes and blue roses: be a mad plant tinkerer

A few weeks ago, I saw an interesting article in the Wall Street Journal (of all places) talking about people who are bioengineering plants at home to develop, among other things, a true blue rose.   I love to see this.  “Tinkerers” have long been a proud tradition of people who make true impacts and discoveries.  I think of the ultimate plant “mad tinkerer” Luther Burbank who established himself as a foremost expert on developing new plants all from his crazy tinkering that developed the potato that you’ll find at nearly every fast food joint and created plants such as the shasta daisy and the wonderberry.  … Continue reading this article “Of potatoes and blue roses: be a mad plant tinkerer”
