Infographic with a BIG grain of salt

Infographics can be great: They’re bright colorful ways to make sometimes complex concepts visual and easy to understand. Sadly, “easy to understand” does not necessarily equal “accurate” and they can also be extremely misleading.

Take this beautifully made image from National Geographic. It is an older image — first posted back in 2011, but it makes the rounds on social media from time to time, and popped up in my facebook newsfeed a couple days ago.… Continue reading this article “Infographic with a BIG grain of salt”

Today in Cucurbit News…

Cucumbers are one of the most widely-grown vegetables in the world.  Baker Creek Heirloom Seeds (a great place to buy unusual and international veggie seeds) lists 51 varieties from North America, Southeast Asia, China, India, Mexico, and Europe.  Dark green ones seem to be in the minority – yellow, white, orange and red skins in shapes round to elongated dominate.

Cukes traditionally have a few nutrients including some Vitamin A from carotenoids and beta carotene, but have never had the reputation as nutritional power house.… Continue reading this article “Today in Cucurbit News…”

A word about GMOs from our visiting GP

I gave a talk to a group of gardeners last year about vegetable and community gardening.  There was a wide variety of gardening experience represented, but one statement from a seasoned gardener bothered me a bit.  And I think my response bothered him a bit too.  I haven’t thought much about it until recently, when a high school English teacher I know told me a student expressed similar ideas in her class.  The erroneous idea from my audience member was this: our tomatoes are being poisoned with ‘germetically modinified’…something something. … Continue reading this article “A word about GMOs from our visiting GP”

The Hottest Thing in…Veg!

Vegetable transplants and herbs were a bright spot last year (and the one previous) for most retail growers and independent garden centers.  Seed and transplant companies have taken note – saw lots of veg and herbs at the normally-ornamental trade shows.  As always, some good ideas, some a bit far-fetched…

Pelleted lettuce seed (much easier to handle) mixes for the grower to create patio-size planters. Not bad! Snipping a few leaves will be fine, but if you eat salad more than once a month, you’re gonna need a bigger pot.… Continue reading this article “The Hottest Thing in…Veg!”

Animal, Vegetable, Irritable

I’m a big Barbara Kingsolver fan. Just finished “Prodigal Summer” – her tall, lanky, introverted, 40-something forest ranger-heroine encounters handsome, mysterious, much younger guy in the woods; sparks fly, etc.  Rowr!  Ahem.

I really enjoyed “Animal, Vegetable, Miracle” when it came out a couple of years ago. It was the perfect dead-of-winter read as she captured flawlessly the itch to grow things, the scent of thawing soil, the joys of mud, the overwhelming greenness of spring, the mess of canning tomatoes.Continue reading this article “Animal, Vegetable, Irritable”

The Approach Graft

Seeing as this blog is called “The Garden Professors” it has been far too long since we’ve given you a lecture on a useful practice for your garden, so this week I thought I’d give you a little how-to demonstration on something called approach grafting.  Approach grafting is a technique that you could use to graft a tomato to a tomato (good if you want to use a disease resistant root with a non-disease resistant top — common in heirloom tomatoes), a tomato stem to a potato root (just a fun project), or an eggplant root to a tomato shoot (good for wet locations).… Continue reading this article “The Approach Graft”

Veggie garden safety

A few months ago I posted a caution about using old pressure-treated timbers for vegetable gardens (see my Sept. 23 posting).  I now routinely get questions about alternatives to these arsenic-laden materials, especially new treated lumber.  What’s in the new wood that makes it rot resistant, and is it dangerous?

Rather than arsenic, new pressure-treated lumber has copper as its active ingredient.  Though it also will leach out of the wood, there is not a human health hazard associated with its uptake by plants or animals. … Continue reading this article “Veggie garden safety”

Veggie gardening science – whaddya know?

I just had a long conversation with Michele Owens (of Garden Rant fame) about vegetable gardening.  This isn’t one of my strong areas, either professionally or personally (I do have containers of herbs, but that’s as far as it goes).  But what piqued my curiosity was her revelation that the vegetable gardening is just as full of myths and misinformation as my field of ornamental landscaping.

I’ve ventured into the realm of vegetable garden science now and then, especially in reference to having soil tests done before planting edibles (good!),… Continue reading this article “Veggie gardening science – whaddya know?”

Eat your veggies! (But not the arsenic, or the chromium, or the lead…)

vegetables_jpg.jpgThe last few years have been a perfect storm for the resurgence of home vegetable (and fruit) gardens.  Grapevines are trellised along sidewalks, herbs replace the grass in parking strips, and tiny gardens of carrots and lettuce are shoehorned into any available spot.  It’s all good  – but we need to be particularly careful about what those plant roots might be taking up along with nutrients and water.
