  • Historical Ginkgo Chopped Down

    February 13, 2013

    Standing Beneath a Giant Ginkgo Tree in Farragut Square

    This morning I was heart-broken to learn that a life of 140+ year old Ginkgo tree was taken – for no good reason. Rather, it was murdered by way of ineptitude.

    Yep, by way of The Garden Professors, I read that an amazing Ginkgo tree was cut down by a contractor in Washington DC. (You’ll notice the report doesn’t credit the work to an arborist, let alone even give them a term like “tree worker.” Somebody instead apparently hired this out to somebody with a chainsaw and no good sense.)

    A few years ago my sister and I were on vacation in Washington and decided to walk through the city from Georgetown to the Mall. Along the way, a giant Ginkgo tree caught my eye. Although I can’t be 100% certain that this tree is the one that was reportedly chopped down, I’d be surprised if it wasn’t. The tree we saw is pictured to the right, and it was huge and gorgeous. And, yes, it was in the same park/square where they cut down a Ginkgo that likely was the largest and oldest of its kind in the capitol.

    Oh, and apparently, they were supposed to cut down sick Ash tree. (Perhaps that’s the very same Ash in green behind me in the photo.) Not sure how in the world a tree professional would mistake one for the other. They’re incredibly different looking trees — even during the dormant months. But, then again, this was a “contractor”. Nobody said anything about hiring a tree professional to do the right job.

    And with that, I’ll end my rant with this: Never let someone who isn’t a certified horticulturist with proven plant identification knowledge get anywhere close to your beloved plants. Or, you may lose a treasure that can never be replaced.

  • Christmas Trees – Rent Now; Plant Later

    November 27, 2012

    Every year around the end of November, I receive an inquiry from a client or reader who is looking for sustainable Christmas tree options, particularly ones that will recycle and/or replant Christmas trees in restoration programs after the holidays. So, I’ve compiled the following list to help you get started finding programs that help take your holiday greens from field to family to forest:

    Living Greens for Happy Future Generations

    Living Greens for Happy Future Generations

    The questions I receive remind me to check in on various programs that allow you to enjoy a living tree and then recycle it by planting it in a restoration area — and yes, with some programs you return the tree and someone else manages the heavy planting work for you. This can be a fantastic option when you consider that traditional Christmas trees like Noble Firs and Douglas Firs mature much too large for smaller residential landscapes.

    Some of these tree-cycling programs provide traditional Firs; others have more eclectic tree offerings based on native trees that are needed in local restoration projects. And, some of these programs encourage you to sponsor a memorial tree or bench or other needed park item instead of bringing a tree into your home. These programs help families and friends create living memorial spaces from the get-go. Read on to learn more about tree programs before you hit the tree lots this year: (more…)

  • Join the Urban Forestry Photography Challenge

    Brilliant, Fragrant Cercidiphyllum japonicum in Fall

    Brilliant, Fragrant Cercidiphyllum japonicum in Fall

    The U.S. Forest Service is challenging U.S. urban citizens to photograph our neighborhood forests, which contribute to the “more than 100 million acres of urban and community forests” that are, in their words, “the hardest working trees in America.”

    Whether we snap a picture of trees lining our streets, capture a stately specimen in our gardens or feature bud break in a nearby park, we can join others in illustrating the beauty of forests of the United States. Plus, we can enter up to two photographs for a chance to win some pretty cool gear from the National Forest Foundation.

    Get the contest details, follow the action and enter your photos here.

    (Thanks to our contributing arborist Katy Bigelow of Bainbridge Island for bringing this event to our attention!)

  • Plant Profile – Ribes sanguineum

    Ribes Mary's Peak

    One of my favorite Pacific Northwest native plants has to be Ribes sanguineum. In mid-April they’re in full glory, so now’s the time to sing their praises!

    This medium size shrub reaches about ten feet tall at maturity. And although it doesn’t get large, it also doesn’t take it long to grow to size in the garden. (Hint: that means you can buy a small one and only have a couple of years to wait until it gets big.) (more…)

  • I Pruned My Tree in Spring & Now It’s Leaking

    April 18, 2011

    When we prune trees as they are are exiting dormancy, sometimes we see the trees leaking fluid from the cuts. And, that’s okay.

    In spring, when trees begin to leaf out, their vascular systems become very active. Water and nutrients begin to travel up from the roots quite readily. Think about tapping Sugar Maples to get delicious Maple syrup. This is done in early spring when “the sap is rising”. That’s the same thing that happens, though perhaps without the same tasty flavor, when our garden trees show seeping moisture from our pruning cuts. Don’t worry about the plant “bleeding” from cuts. It is already working to wall off the points of injury and should be just fine.

    Now, two things you do want to consider when pruning trees with rising sap.

    First, some trees, like Birch may end up showing oozy stains from the rising sap trickling down their otherwise lovely bark. Some choose not to prune birch and other showy bark trees this time of year.

    Second, be sure that what you see oozing is actually just “rising sap”. If your tree has cracks in bark or strange fissures emitting gunky, gelatinous oozes, that may actually be a fungal infection spreading its spores. If in doubt, be sure to have an arborist check it out!
