Landscaping, tree services benefit area property owners

And if you happen to rent one of them, your property will inevitably be upgraded.

In their spare time, two Worthington City employees – Scott Rosenberg and Quinn Kolpin – use their considerable skills, diligence and knowledge bases on businesses that add to the beauty of the tree and landscaped areas in the area.

They operate Kolpin Landscaping and Rosenberg TreeScapes respectively.

Kolpin Landscaping

A few years ago, Quinn Kolpin started doing small landscaping projects.

“I’ve done different things,” he said of jobs he tackled.

“I’ve had people just wanting help planting three plants and others asking, ‘Hey, I tore up this area on my lawn. Could you level it up and put some grass seed down? I want everything to be gone and renewed, ”remarked Kolpin.

“And new builds are really fun,” he added. “You are a blank canvas and you can implement any vision you and the owners have for the space.”

Last summer, Kolpin’s biggest project was closer to home, so to speak; He did extensive landscaping with his parents Robin and Kandy Kolpin in Spirit Lake, Iowa.

“They live on a hill and have a walk-in basement, so I knew transitioning from the front to the back of the house would be challenging,” said Kolpin.

The older Kolpins had recently completed a major remodel of their 1960s home, and the resulting work erased their existing landscaping.

Ultimately, Kolpin installed six retaining walls using unique 70-pound blocks that his parents preferred.

“On my father’s days off, he would pick up a pallet [50 blocks per pallet]”Said Kolpin.

“We went through 10 pallets of blocks so about 500 70 pound blocks were hand installed.

“It was a lot of heavy lifting.”

Using a tractor with a loader function, Kolpin moved four blocks at a time before aligning and stacking them.

“It took a lot of manual labor and heavy lifting, but I got the effect they shot for,” said Kolpin, noting that the project is still awaiting equipment installation this spring.

“And I had to work around some old oak trees in the back – we didn’t want to damage them. I always try to imagine the finished product, and I like to think I have a pretty good eye for it.

“You are very happy with the result.”

Although Kolpin’s availability is limited to evenings and weekends and he is usually a one-man operation, he enjoys the chance to help others improve their yards.

“It’s really enjoyable work and I like the creative aspect,” said Kolpin.

“I like the installation process the most and see projects through to completion – and I enjoy the manual work.”

Rosenberg TreeScapes

Though Scott Rosenberg’s knowledge of trees is considerable – – Going back to undergraduate studies (graduating from South Dakota State University with a park management degree specializing in arboriculture), he continued his quarter-century tenure with the City of Worthington, including his years as the city’s ranger – – It was the terrible ice storms of April 2013 that drove him to go one step further.

“I’ve cut so much this spring and removed trees and dealt with broken branches,” said Rosenberg.

“So I just kept going.”

That year he founded Rosenberg TreeScapes and has been employed ever since.

“It was a gradual process,” said Rosenberg, who added stump removal to his business in 2020.

Amid the coverage in the COVID-19 media, Rosenberg highlights another destructive pest that has received less attention recently: the Emerald Ash Borer (EAB).

“EAB is in Worthington,” confirms Rosenberg.

“Although we didn’t hear that much about it on the news, it hasn’t gone away. It’s still here, and if you want to keep your ash trees healthy, you need to treat them.

“It’s just a matter of the time it can take for EAB to be received – and like with COVID-19 vaccinations and people, the more trees are treated, the more insects are dying and the slower the spread of EAB becomes.”

Rosenberg offers free consultations and offers by appointment. As a longtime resident of Worthington, he has a vested interest in doing the job right.

“I try to educate potential customers about what’s going on with their trees,” said Rosenberg.

“Sometimes a property owner calls because they want a tree to be felled, but if I see them and can see that they are lazy, they may have to fall all the way.”

Rosenberg is also aware that some arboriculture services from outside the region have not served customers well.

“One person paid to have their elm tree treated by another company [from elsewhere] – but when I was asked to look at it, I could see that it was already lazy and that this injection was a waste, ”he said.

His short but firm message?

“If you have an ash in the Worthington area, get it treated [against EAB]”, Riet Rosenberg.

“Don’t wait for your tree to die because you can’t fix what’s already dead,” he continued.

“If you have a healthy tree and you want to keep it that way, treat it.”

With an abundance of tree knowledge, Rosenberg has a wealth of information and advice.

“Pruning younger trees is good practice because you train them on their growing habits as they mature,” he said.

“By cutting smaller branches instead of larger ones, you avoid opening the tree to decay later, and you can shape it however you want.

“You have to remove crisscrossing limbs and branches with bad unions – and anything that is planted too close to a house or other structure has to be trimmed,” he added.

“I wish I had more calls felling 5-year-old trees, as it is much easier and cheaper to solve or prevent problems at this stage than having an 18-inch branch hanging over a roof.”

Rosenberg also has tips on the rate of growth of certain trees (“Some maples grow pretty fast and oaks grow slower, but people want these for other reasons,” he said), tree defects, pruning practices, spacing, and the importance of biodiversity.

“Planting lots of tree species is good because when a beetle or a disease like EAB occurs, you don’t have to treat or lose all of the trees,” Rosenberg said.

“No monoculture.”

Rosenberg is ready to help the area’s owners with their tree needs and appreciates the value of trees.

“The reality is when you plant a tree, you take the long run,” said Rosenberg.

“What you do with your trees and plants today will be of greater benefit to the next generation than you absolutely need.”
