landscape and design from Portland Arborist

Background, letters & thank you . . . #1 - #42

As a service, M. D. Vaden began 1988, in Beaverton, Oregon. Mario Vaden has landscape and tree experience from 1975, with college education for the same profession. Experience and work have spanned throughout Oregon among Portland westside, Ashland, Medford, Klamath, Brookings and Grants Pass - even Crescent City, and Longview. Other work included assisting researchers in Redwood National Park to locate, measure and tag world's tallest trees. Mario Vaden also provides and enjoys Photography and Portraiture. Prints hang between Oregon and Denmark, plus 2 galleries in Crescent City, CA. Images have been used in advertising, magazine cover, websites, books and more.

In short, Mario Vaden (M. D. Vaden) entered horticulture in the mid 70s / early 80s with country clubs and golf courses. Next was university campus experience. 1988 is when business began helping hundreds of homeowners throughout Oregon and the Pacific NW.

Below are some letters and testimonials from 1980 to present, randomly assorted.

Homeowner - March 6, 2009 - Medford, Oregon

Mario did a fantastic job. I had a big big problem with my Red October Glory, it split towards the top. With his eye bolts and cables he was able to bring my sagging tree back to life. I have used him the past 3 years. He does outstanding work and my neighbors have used him since I found him. He has the best rates in Jackson County and trust me, I have received estimates from others. Great arborist and very sad to see him leave our area and move back to Portland.

Administrator: Online Seminars for Municipal Arborists - L. Phillips - November, 2006

Hi Mario,

I just thought you might like to know that your article has produced more comments and is the most popular article ever featured on the Seminars. So far this month, over 50 tests have been recorded on your article. This is more than most articles get in the average two month Seminar.... ... I am even getting emails from people about your article. They are all telling me how good it is and are there any more like this coming. Do you have another topic you would like to write about?

Thanks again for thinking about the Seminars when you wanted to publish.

Letter from Africa to redwood trees

Redwoods Traveler & Arborist - December 18, 2009

South Africa

Hey Mario!

This is Leon ....... just to say again how grateful I am for you taking us for a jaunt in the redwoods yesterday.

It was for me truly awesome and worth every minute. I especially appreciate the fact that we could see some of the really special trees. If I had been on my own I would have just seen a bunch of big trees ... and not known what I was looking at ... Awesome!

I also liked the pace we went ... enough time to drink in everything and not a big rush. ...

Just so you know, I have to tell you that Tracy and I decided to do the walk today you recommended ... That was good advice ... We kinda walked quite fast, so were done in just around 2 hours but it was great to have the sun streaming though the canopy.

Redwood Motel - June, 8, 2011 - Grants Pass , Oregon

Dear Mario,

I'd like to thank you for selecting the Redwood Motel for your stay in Grants Pass. To say the least it was fortuitous and mutually beneficial. .... We were especially honored when you returned to stay a second night with your associates with whom you were preparing to venture out into the local forests to scout out the world's tallest fir trees.

Consultation for motel landscaping and redwood tree photography

After learning of your interest in the tallest trees in the world and your background in horticulture and landscaping, I imposed on you for a critique of the motel grounds. Together with our landscape contractor we walked the grounds as you pointed out numerous areas where you noticed opportunities for improvement. It was an intensive couple of hours that was the equivalent of a crash course in landscaping with a focus on proper pruning, planting, feeding and irrigation. We appreciated water saving ideas and especially your suggestions for repairing damaged and distressed trees. We were amazed by the things that you found that were in need of attention that had gone unnoticed by our landscaping crew. Thanks to you we now know the height of our tallest trees. Our tallest Giant Sequoia at 112 feet, our tallest Costal Redwood at 116 feet ... You identified the enormous old Oak tree that creates a backdrop on our southern exposure as being only 82 feet tall, but looms even larger because of its mass. On your recommendation we will purchase a Blue Giant Sequoia "Glaucum" to round out the variety of trees that adorn our property.

We are expanding the motel with an additional two story family suite structure that will be perched on the highest elevation of our property. It seemed fitting to name the building in honor of the tallest known Coastal Redwood tree, the "Hyperion." We are looking forward to collaborating with you and your associates that discovered the Hyperion tree as we develop the "Hyperion" theme ... We will also be contacting you for pictures of the Hyperion tree and other trees that you have photographed to display in our guest rooms. We appreciate your interest in tallest trees in the world and appreciate your discovery of the Redwood Motel.

Hi Mario! Hoping this note finds you well and happy! ...... OK - here's the scoop: since Justin, Scotty and Brad had to hear so much today about how thrilled we are even still with the work you did here on these trees, it seems only fair I tell you how blown away I am with them too!

They were beyond awesome ...... I just can't stop smiling at what y'all (together) have worked here in this yard. ...... making me even happier about getting to move here! ...... thank you again, for everything!

All best wishes - more later - and be calling you again in a few months! Most sincerely,

Homeowner - June, 2011 - Wilsonville, Oregon

Improvement to Oregon landscape lawn soil

Mario is great to work with and he really knows soil!

Our backyard was a swampy mess most of the year. After digging a few small holes, Mario showed me the soil's structure at different depths. He explained how each depth had probably gotten that way.

About a foot down was a region so dense that water could barely get through it, hence the soupy yard.

The solution was to drill a set of evenly spaced holes deep enough to get beyond the packed zone to the good looking soil beneath. Filling the holes with coarse sand gave the water a channel and yet let the grass grow back over.

It has been a particularly damp spring and the holes have done the trick. No more swamp. The yard is usable almost all yearlong.

Thank you so much for getting in touch with us regarding pruning...We are in Maui right now, however, you can do the pruning any time....After the wonderful job you did with all our pine trees and everything else, I was so dissappointed when you told us you were leaving, and I just kept procrastinating on calling someone else to to it. Now, I'm glad I didn't do it.

Sincerely yours,

To the Oregon Landscape Contractors Board...Mario Vaden...His work was excellent. He kept us informed of the progress as he worked. He explained what he was doing and why. And he fulfilled the work on time and on budget. In addition, he took the time to walk the property with us, to identify each tree by type and characteristics, and recommended landscaping concepts, some of which we adoped in later work on the property. I consider him to be a fine professional, and a pleasure to deal with, and would recommend him to any employer

I was not even sure what a French Drain was, but knew it would provide some insurance for my house on a hill. M. D. Vaden came out, assessed the need, designed the drain, constructed the drain, and left the area looking way better than it looked when the project started. He was very easy to work with, and I'd recommend hm to anyone.

Redwoods Traveler - October 28, 20129 - North Carolina

Hi Mario, I just had to pass along some thanks for all of the incredible information you provided on your website about the Redwoods. My wife and I came out from North Carolina. This was our second California trip in 3 years. In 2010 we went out to see the Sequoias in the central part of the state. That only wet our appetite to really see the big tall ones up north. Prior to our trip, I did extensive research online. I found your website (with associated links) to be absolutely the best source of anything, and it led us to some really incredible areas. We are truly novices, so the only downside was not knowing if we really were looking at some of the big boys on a few hikes. That didn't matter so much, because it was all simply overwhelming ...

... Just wanted to say thanks, Mario!
