Woody Vegetation Chontrol….

By | Arborist Insights, Education, Resources, Tips | No Comments

What do you do with deciduous trees that continue to re-sprout and regrow from cut stumps? What if those trees are located in areas where harsh ( but effective) chemical herbicide use is restricted? Think urban areas and community watersheds.

As I recently found out while visiting a water quality pond, you can use a bio-herbicide called Chontrol Peat Paste.

Details: www.mycologic.ca.

The procedure is fairly simple. Apply a thin layer of the paste to freshly cut stumps from late summer to fall. The pictures below show our native alders, Alnus rubra (Betulaceae family). The trees are interfering with the water quality pond whose function it is to prevent sand, coarse silt and other contaminants from entering environmentally sensitive streams; and to help maintain the flow required to support aquatic life.

The product is only available commercially and it will be interesting to see effectiveness data come in.

Book Review: The Gardener of Versaille

By | Arborist Insights, Books, Reviews | No Comments

This French best seller, written by Alain Baraton, gardener-in-chief at the palace of Versaille, is fantastic! It will appeal to all gardeners and green professionals. Baraton offers us an intimate look at his career path and the history of the famous grounds. His job is not easy. Working under him are eighty gardeners, and they manage 350,000 trees, flowers and plants, plus thirty miles of walkways on 2,100 acres of land. No more enthusiastic amateurs; all new gardeners are required to pass standard government exams.

The gardens have been frequented and loved by kings and queens. Baraton includes many paragraphs on young French kings and their many escapades. Versaille is frequented by lovers looking for secluded spots and this leads us to an interesting quote: “A garden capable of attracting lovers is a success”.
Totally unexpected were the hordes of grandmothers making secret cuttings to take back home.

I was personally fascinated with the details of a gardener’s life and the many great gardeners who worked on the grounds before Baraton. If you like French history or just good stories, you won’t be disappointed. The absolute best story, well worth the price of the book, is that of Louis XIV and his new Superintendent of Finances, Fouquet. Fouquet created an amazing garden at the chateau Vaux-le-Vicomte and threw the party of all parties. Some guests received horses as door prizes! In one account, the young king Louis XIV got very jealous and poor Fouquet was stripped of all of his possessions. Court judges wanted him exiled but that was too mellow for the young king. He threw Fouquet into prison and he died there! Another account says Fouquet was set up. It was his predecessor who abused the treasury.
I highly recommend this book. Five stars.

Get Inspired!

By | Arborist Insights, Education, Events, Landscaping | No Comments

The Inspiration Garden run by the City of Coquitlam is a fun place to visit for all home gardeners and green professionals. I often bike by and stop to brush up on my plant identification skills. And I visit one of my favorite tree species, a specimen of Albizia julibrissin. Its flower fragrance has to be experienced. I can not describe it. It is blooming right now….

There are Ask the Gardener sessions on Thursdays from 6 and 8pm; the iGarden is staffed on Tuesdays, Thursdays, and Saturdays.

If you find yourself in Coquitlam or have some spare time on Saturdays, stop by for a visit. It is located in Town Centre Park, on the corner of Guildford Way and Pipeline Road. Bring your questions, walk through the garden and test your plant knowledge. Or just sit down and relax.

Fight Invasive Plants with One Simple Step

By | Arborist Insights, Landscaping | No Comments

At a Starbucks recently, I ran into a friend who fights invasive plants with a municipal department. After covering the usual enemies -see below-, she shared with me her number one frustration. Homeowners who dump their pots into wild municipal zones. Yes, the local garden stores sell the plants and they’re fine nicely contained in your home garden. Once they’re dumped into open spaces they spread and displace native vegetation, affecting local ecology and soils. Municipalities then spend tax money fighting this problem. Discard your unwanted pots and plants with your Proper landscaper or at your local transfer station. It may even be free for residents.

Annual Cuts

By | Arborist Insights, Education, Landscaping, Seasonal | One Comment

Every year I look for new experiences, both in my personal life and at work. This year I got a chance to work on annual cuts for the first time. This involves line-trimming meadow like fields and buffer zones using heavy-duty line. It can take days, and it will not be done for another year. Large areas are covered by Deere ride-on mowers.

Sometimes it feels like harvest time and the view can be great depending on your exact location. If you are working close to people, stop and let them pass.

​If time permits, harvest ripe blackberries (Rubus discolor) before pushing back the thorny invasive canes. There are other hazards! The tall growth can hide all sorts of objects and small animals. I recommend using a full face shield but they are awkward and expensive. Goggles, ear protection and pants are mandatory. Use a hat, sun screen and bring water.

Best Advice: if you are not using a full face shield, CLOSE YOUR MOUTH! Little voles usually run away from the noise but I did not expect to decapitate two garter snakes in the space of three minutes. And I hate snakes. Harsh previous experience has thought me to look out for improperly discarded doggy bags; the contents defy description after six months of sitting in a meadow. Then there is garbage and rocks which can become nasty projectiles.
It feels great once the work is safely completed.

Follow local gardening guru Steve Whysall and learn!

Imagine my excitement last year when I discovered that my kids were having play-dates with Steve Whysall’s grandkids! Mr. Whysall has been writing about gardening for the Vancouver Sun since 1994. Look for his column on Fridays, usually on page C3. You are guaranteed to learn new things. I often rip out the section and file it.

Mr. Whysall has also published several books and organizes overseas garden tours. While the tours are attractive they are way over my family budget. I am, however, ready to plug what I consider to be his most useful book.

Best plant picks, slightly beat up and autographed, has served me really well. The book is a neat month by month guide for our West Coast gardens. I use it to practice plant identification and to review the list of garden tasks to be performed on a particular month. As the seasons pile up, I can run through the list of plants much quicker. Always learn about new plants and review them.

Industrial athletes…..

By | Education, Resources, Tips | No Comments

IMG00495-20090830-1233I came across the term “industrial athlete” while reading an article on caring for your body in Arborist News (February 2013). All green industry workers work hard in the field all year and taking care of their bodies is critical to their work performance.
Some highlights. Many workers don’t eat enough, skimping on breakfast and skipping lunch because of the sluggishness they experience after eating. Proper hydration is important; excessive caffeine consumption contributes to dehydration.
Rest and recovery are important; and so is sleep.
Workers who take care of their bodies perform better and make a larger contribution to their company’s success. Review the article and take care of your body Properly!

Nature Pill?

By | Arborist Insights, Landscaping | No Comments

We know conclusively that we can derive health benefits from spending time in nature, or even just by looking at nature. The Japanese have their own research called shinrin-yoku or forest bathing. Read more on this here:http://www.shinrin-yoku.org/shinrin-yoku.html

Now some researchers are working on the big remaining questions: What dose of nature exposure is needed to achieve maximum mental and physical health benefits? (How long and how frequently?) Perhaps one day we will get nature pills. Read more here: http://dirt.asla.org/2015/06/03/what-dose-of-nature-do-we-need-to-feel-better/

This all means that having beautiful, healthy landscaping around your house or business can be good for your health!

Meet My Hero….

By | Arborist Insights, Education, Resources | One Comment

Linda_Chalker-Scott-recentDr. Linda Chalker-Scott is my hero. She is an associate professor and extension urban horticulturist at Washington State University.

In her books The Informed gardener and The informed gardener blooms again she uses science to examine common garden and landscape myths. Warning: she explodes many common myths.

Sustainable Landscape and Gardens
is more of a technical manual which can be ordered directly from Linda. Her latest book How plants work is a fantastic book for gardeners everywhere and green professionals. I finished the book while travelling in Japan in late May and my review will appear in a future blog.
Linda also writes in popular magazines and has published extensively in scientific literature. We have already seen reference to her technical paper on mulches in an earlier blog.

So why a hero?

  1. She is a Ph.D. and gardener who uses sound science
  2. She translates hard science into understandable and thus usable information for all gardeners and green professionals, and, this is important
  3. She is “local”

If you are a gardener or green professional, you will love her work. If you read it and study it, it will make you a better professional or gardener. Google her today and thank me later. I hope to meet her at a future seminar…..
