Invasive Species vs. Non-Invasive Alternatives: Part 1

Contributed by Curtis Hawley

Inspired gardeners often ask our crew with hopeful expressions on their faces: “I was driving down the street the other day and saw this amazing plant, could you get me one of those?” As knowledgeable horticulturists, it is our responsibility to be aware of all aspects of a plant before we order you the latest garden showstopper. We first go through an in-depth list to learn about the plant including sun/shade requirement, moisture tolerance, acidity/alkalinity preference and competition with neighboring plants. Sometimes we learn through this process that a requested plant is considered an invasive species.

When it comes to plants, the definition of invasive can get a little muddied. For all practical purposes, an invasive species is a non-native plant that is introduced to a new environment where it behaves in a rather aggressive manner due to very little competition and/or extremely ideal growing conditions. Although Poison Ivy or Golden Rod can be rather aggressive at times, they are not considered invasive species since they’re native plants. A couple of examples of common invasive species are Oriental Bittersweet and Japanese Knotweed. These are both very aggressive plants often found growing on roadsides and taking over areas quickly. We don’t get many requests for Knotweed, so let’s talk about some popular plants that do qualify as invasives and some excellent, eye catching native alternatives.

Round 1: Burning Bush (Euonymus alatus) vs. Viburnum nudum ‘Winterthur’

Burning BushInvasive: Burning Bush (Euonymus alatus)   

This shrub is commonly requested in the fall. Admittedly, its 4-week long bright fiery red display is quite stunning. Outside of its fall showcase, however, I personally don’t find this shrub to be very aesthetically pleasing, and of course because it’s invasive I don’t recommend it! When someone asks for this Viburnum, I like to present my favorite alternative that I think outdoes it while being more friendly to neighboring native plants.

Virburnum nudum WinterthurNon-Invasive Alternative: Viburnum nudum ‘Winterthur’   

This is a native plant, so that’s a good place to start. Not only is a native plant by definition not invasive, but it’s usually not overly aggressive either. But you know what’s even better about native plants? They’re being grown in their natural environment, meaning there’s a very high likelihood that the plant will thrive!

Here are some other great advantages of this non-invasive alternative:

  • Much nicer flower show in May/June (Burning Bush has a non-distinct flower)
  • Flowers are followed by a colorful fruit structure that changes color from red to blue throughout summer
  • Fall colors feature maroon to dark red-purple
  • Great food source for pollinators
  • Better ornamental shaping from pruning (Burning bush tends to get sheared into “meatballs”)

 

Stay tuned for Parts 2 and 3 of the Invasive vs. Non-Invasive Plant Showdown, including another very popular shrub and one of the most popular plants you can still buy today…

“We Need to Block that View!” – Creating Privacy with Landscaping

Contributed by Christie Dustman

I can’t count the number of times I have heard someone say, “We need to block that view!” In fact, many people go on to describe how they wave to their neighbor at night, kitchen window to kitchen window.

While we all love living in proximity to the city, we also want our privacy. How can landscaping help with this dilemma?

This is the rub: we want plants to do lots of things for us, but sometimes using plants to block out a particular view is almost as visually unappealing as that view itself. For example, think of that house you drive by with an A/C unit enclosed by a fence that screams, “Hey, A/C unit here!” 

This Saturday, April 22nd at 9am, I’m hosting a Walk and Talk at Allandale Farm to discuss ways to approach this common dilemma. Register here and come to learn some new options! 

Check out other Walk and Talks I’m hosting at Allandale Farm this spring here. I hope to see you at one!

Pruning Workshops at Allandale Farm April 15, 2017

Contributed by Christie Dustman

Every spring, my internal panic measure ratchets up as the weather warms. Suddenly, all of the woody plants in my garden seem to need immediate help and I feel pressured to work on each plant. For each of these plants, I have to use my brain as well as my tools. It takes a lot more brain power to prune than simpler tasks like weeding or deadheading. Imagine that – pruning my plants engages my brain as much as my tools!

For many people, spring brings up those perennial questions of how, where, why and when to prune woody plants such as shrubs, roses and smaller trees: “What plants should I touch now?”, “How far should I cut it and where?”, and for almost all folks, “Am I going to kill it?”

Allandale Farm

Good news! I am teaching a 2-hour pruning workshop, “Pruning for Healthy Plants,” at Allandale Farm this Saturday, April 15th at 9am and again at 11:30am. I will show my tools and tool belt, then delve into the indispensable thought process that should precede any cutting. Just like you have an end goal when you walk into a hair salon, you should have clear goals and reasoning behind any pruning actions. As we all know, a bad hair cut can really ruin your day!

You can register here – hurry up, space is limited!

I’ll be teaching four other classes at Allandale Farm on Saturdays this month and next. To see the full listing, check out the events page on Allandale Farm’s website.

Arborway Tree Care: A Trusted Partner in Business

Contributed by Libby Coley

Being a trusted adviser for our clients means taking the time to vet other colleague companies who provide complementary landscape services. Lucky for us, Arborway Tree Care is one of our trusted partners in business. We recently met up with Bob Kelley, Plant Health Care Manager and ISA Certified Arborist at Arborway, to get the inside scoop on the company: their services, company philosophy, and some tips of the trade!

Arborway Tree Care is a full-service tree company that has served metro Boston for 40 years. Arborway offers many services that complement CD & Co. These include plant health care, health maintenance and structural shade tree pruning, structural cabling and bracing, crane services, lot clearing, storm damage and stump grinding. Many of our clients use Arborway Tree Care for their disease and pest management services.

Bob joined the Arborway team four years ago. As Plant Health Care Manager and ISA Certified Arborist, Bob wears many hats. In any given week, you can find him doing tree work and plant health care in the field, in the office doing paperwork, or meeting clients. Bob shared that one of the best parts of his job is talking with clients about what’s going on with their trees and why. Educating their customers and thoughtful planning are important to Arborway.

We asked Bob what he thinks a property owner should know in terms of tree care:

  • Bob said that adequate water uptake is the most pressing issue these days for trees and plants, especially in light of the last three years of drought. In previous years, Bob stressed the importance of watering perennials and shrubs from July 1st to the end of the growing season (typically around the middle of October) in the absence of normal rainfall, but now he stresses the importance of watering all plants. He also advises homeowners to water large shade trees if they are of high value to the property.
  • Bob stresses safety above everything when it comes to trees. It’s crucial that trees are structurally sound, especially in stressful conditions such as drought and storms which can tip the tree into irrevocable failure.
  • Plant Health Care. Bob points out that monitoring and treating plants for pests and diseases is the best way to keep a landscape healthy.

What are the biggest challenges facing trees in 2017? Bob anticipates a quantifiably larger rate of tree decline and pest/disease problems after three continuous years of drought. Three is a key number here – healthy trees can survive on stored energy for three years, but any additional stress makes them more susceptible to health issues after that point. Bob also highlighted that the gypsy moth and winter moth hatch in early spring and noted that mid-March to July 1st is Arborway’s busiest time of year. During this short period of time, their Plant Health Care crews apply several different applications before buds break and after leaf emergence including pesticides and fungicides.

The Challenge of Finding Skilled Labor: Discovering a New Approach

Contributed by Jim Lynn

Finding a few qualified candidates to hire out of 7.9 million people can be trickier than you might think. 7.9 MILLION is how many people are currently unemployed in the U.S. according to the Bureau of Labor Statistics. Surely there must be plenty of great horticultural candidates in that huge number. It should be easy to find somebody who wants to work in our industry, right? Think again.

When looking for a strong candidate to work with our crew at Christie Dustman & Co., we are looking for a well-rounded individual that has experience, education, passion, and stamina. We don’t think that’s too much to ask for, is it? Well, it can be difficult to find such an individual who doesn’t mind working in all kinds of weather conditions!

We took a different approach to hiring this year and tried something new: if we can’t find candidates to match our needs, maybe we can take the candidates we have coming in and train them into the fine gardeners we are looking for!

hiring - JhylikThis year, we had two candidates for crew member positions who were eager to get into the landscaping industry but didn’t have the experience or rounded knowledge base that we were looking for. However, both were willing to learn, have a passion for plants and importantly, are likable. Thus, they were high potential candidates, and we let them join the team for a trial period with the crew in the field. On a typical tryout, we have each individual work with each of hiring - Sarahour crew members to get feedback and see how adaptable and teachable they are.

Our new hiring approach has been a great success. If every tryout ended in success we wouldn’t have to have them, but this year we were lucky – we added two new crew members through this process! Welcome to Jhylik and Sarah!

It’s Time to Start Thinking About Bulbs!

Hello Garden Lovers,Allium Globemaster

It’s bulb time! We are planting bulb “overlays” for our Clients’ gardens, meaning that we plan a sequenced bulb display (big or small) and plant them in between your other plants in the garden. these bulbs bloom from March to May, giving color and interest well before your garden gets into gear.

Ornithogalum nutans Silver BellsWith bulbs, it is not uncommon to plant 500 crocus, for example, to get an abundant visual impact. This means that bulbs can cost $300 to $500 to $700 in materials, then double it for the planting labor. We plant each bulb to make sure it is at the proper depth and “right side up.

Email or call us by Friday, October 21st if you’re interested in bringing some early spring color to your gardens! I will need to know what you are comfortable spending and with that in mind, I can tell Narcissus Little Gemyou what to plant and where to plant it for the best impact.

Best,

Christie

Falling for Containers

Contributed by Tim Wholey

Reflecting on this past summer, one word jumps out – RAIN – or more specifically, the lack of it.  It was one of the hottest and driest on record. We added “deep watering” to our garden maintenance regime this past summer and let many hoses trickle on plants at our clients’ homes during this severe drought. Even with hoses and an irrigation system, the lack of rain has been hard on gardens. The poor plants just looked hot and brown!

This brings me to my passion: outdoor containers. I love that containers are easy to water, require very little water overall – and it doesn’t take much time! Quite different than large gardens!

With our fall container season starting this week, I have to say that I’m looking forward to it this year more than ever. I’ve just started replacing summer blooms with flowers reflecting all the colors of the new season:  golds, yellows, reds, oranges and purples. It has been a welcome change for all of us.

Consider the ease and beauty burst of a container for this fall at your house – I’d love to work with you!

A Design for All Times

Contributed by Curtis Hawley

“I have all my life been considering distant effects and always sacrificing immediate success and applause to that of the future.”  Frederick Law Olmsted

A Clearing in the DistanceEarlier this year, I had the good fortune of running into a great read, A Clearing in the Distance: Frederick Law Olmsted and America in the Nineteenth Century by Witold Rybczynski. Being new to the horticultural field, I’ve been exposed to a lot of new and exciting things, and while working in and around Greater Boston, one can’t go too long without seeing the name Olmsted. A colleague enlightened me to the fact that Frederick Law Olmsted designed not only Boston’s Emerald Necklace, but also New York City’s Central Park. I immediately thought, “That’s quite an accomplishment!”, but what was more impressive is that those accomplishments turned out to be just a small part of quite a varied and accomplished career.

I think we all have a tendency to examine our own lives when we read about another’s life. Like me, I appreciated that Olmsted took his time early on in his career to feel out exactly what his passions and interests were. By taking his time, I mean he traveled the world, started a farm, explored the master gardens of Europe, authored nationwide publications and literature, was a strong voice against slavery and was the precursor to the American Red Cross during the Civil War, amongst other achievements.Emerald Necklace

For me, one of the biggest takeaways from his life and career was his propensity for long term planning. This skill exemplified his intelligence but much more so his immense generosity. To plan something so lasting as the Buffalo, New York Park System or The Biltmore Estate is a deliberate gift to future generations, one that he knowingly wouldn’t be able to fully appreciate in his own time. Imagine a painter or musician crafting a fresco or ballad but never being able to see it or listen to it? What vision indeed!

Visiting and working in our client’s gardens is a truly great opportunity and one that I genuinely enjoy. Installing new additions to a garden, pruning and shaping an ornamental tree, or even just editing a garden bed can have quite the long term impact on a garden. Seeing now that I have the ability to leave a more lasting impression than I might have initially realized only further enhances that experience.
