Veg Display Garden

A simple garden filled with surplus veg starts we installed this on Saturday, July 9th.

 Take a walk in Arboretum. Breath fresh air. See beauty.
 Feel happier. The science of it all says gardens are therapeutic. Have you ever had that experience? The thrill of seeing your plants grow and thrive? The pleasure of seeing a beautiful bloom?
So often we just rumble along on the daily grind.

 Don't rumble around all the time. Take a break.

 Stop for the Arboretum.

You will feel good when you do.

The Essence of Volunteerism

The essence of volunteerism is not giving 

part of a surplus one doesn't need,

but giving part of one's self.

Such giving is more than a duty of the heart,

but a way people help themselves

by satisfying the deeper spiritual needs

that represent the best that is in us.

United Way Day of Caring

  Friday was the best day. I had 17 volunteers and  myself, Peter Maurer and Van totaling 20 people at the Day of Caring.

 It was sunny and gorgeous. 

Join us tomorrow as we scrabble with the Weasel in the Arbie.

Tomorrow is our regular second Saturday work-party in the Arboretum.

It will also be Ellen Wanless's last day. 

If you haven't signed up and wish to come, please feel that you can. I will have extra sandwiches. You all are most welcome. I would love to have as many of you as possible to have fun and work with Ellen as she spends her last day with us.

Bonus,the Garden Center will be open from 11 to 3!

If you don't know Ellen, you should. She is a gracious and charming lady. She holds her undergraduate degree in art but like many of us, is a horticulturalist at heart. Upon moving to Washington state, she went on to Edmunds LHO Program and received her degree in Horticulture there. Her father was an engineer and I believe that is where her rigorous scientific mind developed. Ellen and Bill operate Brooke Wanless Gardens, a very successful local gardening business. Bill, her dear spouse has also contributed his time monthly these past year to the Arboretum as a Certified Arborist. Bill and Ellen deserve much credit for their generosity of time and effort in our Arboretum. 

Ellen has spent the last 3 years working with the CoHort on 2nd Saturdays. She has focused her efforts on the Lamiastrum galeobdolen removal.She did some valuable research at UW for us before agreeing to tackle this major effort in the Arboretum.

 Last year Ellen and I gave a talk at the Annual IPM workshop Sponsored by Seattle Public Utilities and funded by the Local Hazardous Waste Management Program in King County; held on campus. Our talk focused on the L. galeobdolen and the efforts taking place in the Arboretum by the Cohort. In our research for the project, we found that our cousins in England call this plant Weasel Snout!

From then on of course, that is what we just had to call it.It was just too good a name to pass up.

Join us tomorrow as we scrabble with the Weasel in the Arbie, and celebrate Ellen.

Yours in the trees,

Claire

My Sunday Volunteer

From the South Seattle Community College Arboretum Programs Coordinator

A few Sundays ago, I  was visiting the Arboretum with a friend. It was a gorgeous afternoon. I began the tour on my usual path from the Entry Garden to Sensory Garden. As we made our way through to the Helen Sutton Rose Garden I  saw a lady seated in the Arbor and a fellow with her.  This fellow was busy, vigorously pulling on down our Wisteria Vine!
Surprised and a bit alarmed, I walked over and quietly introduced myself, explaining to him my role in The Arboretum at South Seattle College and then asked him what he was up to.


 He was very happy to complain to me that he was rather upset about the state of the vine.
"Oh my Yes" I agreed with him. It was wild and the laterals were running everywhere. Cats Turnbull of Plant Amnesty Cass Turnbull jokes, "Wisteria is Latin for work". 

I told  him that the vine was on our  'to do' list, explaining that we were temporarily short handed.  We relieved on students, interns and volunteers for the Arboretum gardens. Fine pruning was usually saved for students.

As I said, it was a beautiful day. And as folks love to do,we began 'visiting'. Chatting in general about the vine, the arboretum and other things. I soon discovered that we had friends in common. I knew the pastor at their church in West Seattle. And  they knew of Helen Sutton and were acquainted with Margaret (Peggy) Culler! These two women, who have now passed on, were instrumental in the development of the Arboretum and Botanical Garden we know today.

Don't folks love to make connections? Whose yo' daddy and all that. When I asked if they knew "Peggy",  his wife  replied " is that Margaret you are talking about"? Why yes! Peggy was a long time supporter of the Arboretum and South Seattle Community College. establishing rapport, making connections. Now, my new friends (vandalizing the garden) and I were  having a very nice visit together.

Suddenly my light bulb came on! Yes, dear readers that does happen! It occurred to me to ask if they would like to volunteer and help with the vine. I respectfully queried my Sunday gentleman visitor on his pruning experience ( he is probably about the age of my dad, somewhere in his 80's) So, he gives me this 'look', as you might imagine. You know  that look, the  'what do you mean do I know what I am doing?' look.  Well still; I had to ask about his pruning knowledge.

We worked it all out and this kind couple Mr. Bob and his dear wife, came back later to care for the vine. He did a  splendid job! He took all (well most) of the laterals down to their hands (the shortened lateral looks like a hand after several years of pruning).  All I had left to do was hoist the bag to the clean green container.

It 'pays' to go to the Arboretum on my off days. I never know what I am going to find there. Somedays I might find a sweet 'Sunday Volunteer'.

IPM WORKSHOP REPORT and A BIG THANKS TO ALL YOU COHORT VOLUNTEERS!

 *Out Damn 'Weasel Snout' Out!

Last week SSCC hosted an IMP  workshop. What is IPM? Integrated Pest Management.  Nowadays we like to refer to it as Plant Health Care. Here in Seattle it is sponsored by Seattle Public Utilities and funded by the Local Hazardous Waste Management Program in King County with support from South Seattle Community College and Seattle University. Below is a great description that I found at the University of Georgia.

IPM

An IPM mindset demands that all options---chemical and non-chemical---be considered when developing a pest management action plan." 1

 IPM workshops are, of course there to help those of us in the field who are getting our credits for pesticide licenses,or our educational goals.  IPM is used all over the country.This is how my friend lets call him Mr. B, likes to describe me. "A Tree Hugger". OK, I am a Tree Hugger from way back.  Mr. B, who lives in Georgia has a home in the North Georgia Mountains. He loves his trees too. Over yonder, in states from Maine to Georgia, they are experiencing  problems with the Woolly Adelgid 2. in the Tsuga canadensis Eastern Hemlock.  Mr B a very intelligent and proactive person attended workshops to learn how to help save the beloved Eastern Hemlock. It was recommended to use an injectable pesticide in the base of the trunks and that is supposed to save them. I hope that it does. In the case of the Wooly Adelgid an IPM approach of injections seem to be the best possible solution.

 This year at the Seattle IPM workshop I had the privilege of co- presenting a talk along with our principal volunteer Ellen Wanless, of Brooke Wanless Gardens,LLC. Our presentation was about the Lamiastrum galeobdolon removal project in the Arboretum. We began the work of removing this weed  in Nov 2008. There was a lot of it, and when we began we felt like we were bailing out the Ship With a Spoon. But it is beginning to show promise now.

So, for a tree hugger like me who wants to do good for the planet, I am happy to report to you that the presentation at the workshop appeared to be successful. We  wanted to organize a presentation that would be meaningful to people. We also felt it was important to be as strictly scientific as we could possibly be. We presented the project in a time-line that showed our research, progress and where we are planning to take it now, with thanks and credits too.

Here is a little synopsis of our presentation. This will give you and idea as to what all we have been doing with this project.

Begin

At the outset of the project back in '08, Ellen met with Van for a discussion on what area in the Arboretum that she could assist volunteering in. Van suggested the removal of  Lamiastrum  galeobdolon Yellow Archangel or Weasel Snout as he is concerned with our proximity to the West Duwamish Green Belt.

  Research
 Ellen did a major amount of research with folks like Linda Chalker-Scott of WSU and Dr. Sarah Reichard  from the University of Washington. She also used her notes from Arthur Lee Jacobson's talks on mechanical management. We were lucky to know Wendy DesCamps, a woman who is working on her masters with this very plant! Wendy shared with us a lot of valuable assistance and information. Other valuable information was provided by Tracy Osborn, formerly of the Rhododendron Species Garden.

 While Ellen was getting started with this, I was busy organizing the Volunteer Cohort. A volunteer group for maintenance in the Arboretum had never before been implemented and we felt that it was a great time to start. We had lost our head gardener in 2006 and for a while the college grounds crew assisted in the Arboretum, but they gradually have reduced their time spent in the Arboretum due to the demands on their own operations.Van and the college gave the go-ahead for this project in late August of 2008.
 About this time the students were pushing the college to 'go green' and stop using pesticides in the Arboretum. You can imagine that the place began to look a little shabby on the edges.

I started with research also. I was able to interview Bellevue Botanical Gardens, Washington Park Arboretum and used resources from the United Way of King County.   Slowly I began to knit together a small group of volunteers and most of them were students in the LHO program!

Documentation 

REGENERATION OR 'THINGS WANT TO LIVE'!
Long Fine Roots make for difficult removal.
 Plant can regenerate from these fine roots left behind.
Plant can regenerate from any part of the stem with a node.
 Plant can reseed too.

We had plenty of  documentation and photo's galore.  I took a lot of pictures. I kept records of each work party, where we worked, who was there and how long we worked.

  Lamiastrum galeobdolon Project Begins Nov 2008

 People like to work on weed removal by hand, grubbing away. Or some like to spray it up with herbicides. Then, thinking that they have done this fabulous job clearing up the weeds,we go off and  forget about it. Months later the weed is back. Next up is something that many of us are guilty of. We fall into the, "this method doesn't work" trap. With this in mind we began to look ahead at the Weasel Snout; and how long the project would take. We thought," oh, we'll be finished with this maybe by next year. Not.

The 3 Year Plan

Arthur Lee recommends 3 years for a mechanical method of removal. We may not be able to completely eradicate any one weed, but we do want control.

(I only want control of the TV remote, but that will never happen with 4 children)

  Tell me something good. We have had successes. One success is under the Myrica california between the Entry and Sensory Gardens. This area about 600 SF, was processed in May 2009 with 5 people. It was choked with the Weasel Snout and it is now very clean. But there are 'pop ups'. These are easily managed by hand weeding. As long as you remember to be in the long range plan mode.

Myrica california at the Entry/Sensory Garden.

 The L. galeobdolon project has not been with out its problems. We have had a couple of  failures. One in particular is over on the Dry Creek Bed Hillside. 

 We failed there, due to some on-site decision making that did not work for us. The Fushia were important for us to try and save so, we sheared everything back and mulched. The Fushia came back big time and guess what? Yep, so did the the L.galeobdolon. Weasel Snout won that day but we learned a valuable lesson. Do
your research, have a plan, work the plan.

 Tools and Cardboard

Don't you love your tools? We love our tools. We use shears, hori hori's, diggers, tarps, fan rakes, brooms, wheel barrows, clean processed cardboard. Oh, and I always have my camera. Even if it is just the cell phone. Tool time tip: Remember when you are shearing get right down onto the surface of the soil, if you chomp into a rock or hard bit ease up and try not to nick the shears. This is the most effective shearing method. Also, take the shears at the end of the day, clean em up, rasp, file and oil your tools. Love your tools.

Key tip: overlap the cardboard generously.
Starve the plant of light.

Methods 

 Hand removal is possible, but be careful in where you are working and at what time of year. During the growing season the surrounding plant roots may be damaged by hand weeding. Especially be careful with the Rhododendron  roots. 

Hand weeding therefore, is not recommended for the grow season around the Rhodies roots, chose instead our method of  shearing to the roots. Then, sheet mulch with the mulch at 4 to 6 inches.

  

 Where Do We Go From Here?

 OK, fine.What are we doing now? Here is the plan, chosen in part due to the scale of the Arboretum and lack of time and limited assistance. We chose the following method. Shear the plant, Sheet mulch, Monitor for Pop ups ( new growth) and remove the pop ups.

Trials

 Van, Ellen and I have met and decided to follow up with trials of our different methods.

 There is always concerns about the cardboard gas to air exchange. One wants to know what works best where.

Three methods.

1. Choose to use sheet mulch with the mulch level at 4" to 6".  

2. Use mulch only, up to 12"

3. Lastly go in and shear weekly, starving the plant.

Make a Plan - Work Your Plan

 As of now the L. galeobdolon is being placed in the Arboretum's long range maintenance plans. Yes. We feel good about this and hope that you do too.

  Let me just say a huge thanks to all of you, the Cohort Volunteers and everyone who has supported this project.  It is you  who made the Lamiatrum galeobdolon Project as successful as it has been. You all have been so great for showing up and for helping out on Second Saturdays. It has made  a tremendous difference in the Arboretum. Thanks again.

CoHorts and Docents.

  Tools We Love.

*Yellow Archangel is just too beautiful a phrase for our pesty L. galeobdolon. Ellen found a reference to this plant, calling it 'weasel snout'. We love it.
