Are Pretty Flowers Useful?

Yesterday I had the opportunity to listen to Marla Spivak, a very highly regarded bee scientist, talk about how bees defend themselves from disease.  Very interesting stuff.  I took a lot of information away from the talk, two bits of which I want to share with you.

The first is a vocabulary word — propolis – go ahead, google it (I don’t think too much inappropriate stuff will pop up) – it’s an antimicrobial “ointment” which bees create from stuff like the resins on tree buds.… Continue reading this article “Are Pretty Flowers Useful?”

Is “lasagna gardening” really worth the effort?

This week I got a complimentary copy of Urban Farm, dedicated to “sustainable city living.”  The cover story is Lasagna Giardino – follow this recipe for a lasagna garden that grows perfect plants – Italian or not.

This is not a new idea, but was popularized several years ago as a way of preparing soil for planting.  The article relates the steps:

1)  Prepare the ground by mowing the lawn
2)  Dig up the first 12″ of soil (double digging)
3)  Place a layer of “noodles” (paper and cardboard are popular) – the low nutrient material
4)  Place a layer of “sauce” (the green material)
5)  Repeat as often as you like and “let it cook”

I like the first step of this. … Continue reading this article “Is “lasagna gardening” really worth the effort?”

It’s Spring-o’clock Somewhere…

We’re supposed to get an inch or two of snow tomorrow.  It was 75 degrees last week. Typical schizophrenic spring weather. But spring was already in full bloom a few weeks ago in Dallas, Texas.  Our group of Virginia Tech floriculture faculty and grad students visited for the National Floriculture Forum, a meeting of researchers and educators. It was organized by Texas A&M and hosted by the Dallas Arboretum, home of uber-horticulturist Jimmy Turner.

The Arb was right in the middle of their “Dallas Blooms” festival – they plant half a million spring bulbs each year for the most amazing show this side of Keukenhof. … Continue reading this article “It’s Spring-o’clock Somewhere…”

Keep Calm and Carry On: Part II

Recently I posted that many of the “rules” that gardeners cling to so tightly regarding tree planting (i.e., dig the planting hole 3 times the width of the root ball, always amend the backfill with organic matter) are probably better considered ‘suggestions’ than rules.  While these practices won’t hurt, there are much better ways to spend time and effort to ensure long-term survival when planting a tree.  Here are the top four:

Irrigate.  No matter how much time and effort goes into the ‘perfect’ planting hole; for most parts of the country, trees that are not irrigated after planting are doomed.  … Continue reading this article “Keep Calm and Carry On: Part II”

Looks like larch!

Great debate on the identity of Friday’s mystery plant! Several of you guessed larch, and this particular one is contorted larch (Larix kaempferi ‘Diane’), a cultivar of Japanese larch:

(As an FYI to a side discussion in the comments, tamarack is the common name for American larch, Larix laricina.)

And the eagle eye award to those of you who saw that YES! WE FINALLY HAVE A SEARCH FUNCTION on the blog! It’s still being tweaked so that the results pages will be a little more sophisticated, but it works.… Continue reading this article “Looks like larch!”

Friday’s quiz…a twofer!

Here’s the mystery plant part for the week:

Now for question number two:  there’s something new on the blog this week.  Can you find it?

Answers on Monday!

How to get the information out?

Over the last two weeks I’ve been dwelling on the information that people get about gardening from various sources.  I’m not talking about really serious gardeners – I’m talking about the guy  down the block who might grow six tomatoes, two cucumbers, and a head of lettuce.  He’s got 6 trees on his property and he keeps his lawn nice, but not immaculate, by mowing weekly and fertilizing and applying herbicides once a year.  Where is this guy getting his gardening information? … Continue reading this article “How to get the information out?”

Plant containers – does size really matter?

A few days ago I got a question from Cynthia about “potting up.”  For those of you for whom this is an unknown phrase (and no, it’s not a euphemism for a certain herbal activity), it refers to the practice of moving plants into ever larger containers.  She was wondering if there was any “real science” behind the practice – in other words, why not just start out with a larger container?

Hah! I needed no further encouragement and spent several days collecting and reading decades’ worth of research.… Continue reading this article “Plant containers – does size really matter?”

Mouse Tombstones

Doing this…


I must identify each and every Wave petunia!

leads to this…

and this…

Unfortunately, the second and third photo are from a college teaching and display garden. There are a lot of inexpensive yet more attractive ways to relate plant identification to your visitors.

We all do this, of course, to some extent in our home gardens. Walk around with weird plant in hand, dig hole, stick it in, say to self "I’ll come back and get that label to add to my (pick one) Excel garden database/bag of random tags/photographic memory."… Continue reading this article “Mouse Tombstones”

Heck, it’s hellebore!

You were too smart for me this week.  Though my husband was convinced that Friday’s photo was not enough to help identify the plant, JRR, Foy, and an unnamed commenter all recognized hellebore:

Always a welcome sight in the spring.  And don’t be fooled by those old wives’ tales that hellebores don’t like wood chip mulches. These beauties have been in wood chip mulches all their lives, and not only do they do great, their seedlings do as well.
