As many of you know, I have brought my dog to work with for the last several years. You all got to know the gentle white giant named Garin. My faithful German wirehaired pointer became a fixture here at Christensen’s.

I lost Garin in 2020 after 15 wonderful years. He was there for me through a very large part of my adult life. The birth of my son, divorce, getting remarried, accepting the bonus kids and animals into the house (Two bonus kids, three dogs, three cats. Yep, my wife is an animal lover.) 

Whether it is the ladies, who Jango has trained it requires a dog cookie from my office for them to pass by to the bathroom, or the sales team in the office who hide their lunch, but bring in treats for him or our perennial staff who cannot let him pass without getting a “fix” of Jango or the conference room chair that Jango has claimed as his during our meetings (complete with the meeting stopping groan as he rolls over, that leads to a round of laughter.), it is clear that Jango has taken a place on the staff of Christensen’s.

Make sure you get to see Jango the next time you stop in. He is great at taking away the stress of our season and putting a smile on your face with just a few strokes of his coat.

As I sit here in the lull of August thinking about what to write my article on, nothing comes to mind. Usually, ideas will come to mind pretty quickly, but with 2 weeks away from getting married and all the prep and planning, topic ideas are just not flowing at the moment!

However, we had a meeting to inform our staff about an invasive pest that is making its way to Michigan, The Spotted Lanternfly (Lycorma delicatula). I’ve done an article about Cicadas in the past, so I thought this would be a good opportunity to share a little about what we learned in an effort to help inform you.

Spotted Lanternflies are native to China, Vietnam, and India. It was first reported in the states in 2014; believed to have come in on a shipment of landscape rocks found in Pennsylvania. Since then, they have been more detected in the eastern states such as Maryland, Delaware, Virginia, and New Jersey, slowly moving closer to Michigan over the past few years. Just this month, a small batch was found in Pontiac, MI, and were likely brought in on a shipment of plant material or even on the truck itself. Think of all the stinkbugs you see in the spring. Those also came from China to Pennsylvania and have now spread across the U.S in a matter of 25 years. Sound Familiar?

The problem with these pests is that they can wreak havoc on farms, forests, grape vineyards, and orchards. They do not necessarily kill the plant but instead contribute to the plant’s mortality. They first weaken the plant by sucking sap from the hardwood areas and restricting photosynthesis. Doing so results in well… A LOT of pooping called ‘Honeydew’. This attracts insects, disease, and sooty mold, aiding in the possible fatality of the crop. Host plants for Spotted Lanternflies to feed on include but are not limited to species such as maples, walnut, willows, apple, and grape. Their primary choice is a tree native to China called Tree of Heaven (Ailanthus Altissima) which looks like a large Sumac that can reach 60’ in height. It is a very invasive tree that forms thickets all over the U.S. and Canada.

After this, they reach their adult phase and will grow wings and reach up to an inch in length. The body becomes black in color. The red that made them highly visible before is now only on their hind wings which are now covered by their forewings that are grey with black spots. They complete their cycle by laying eggs in September-November and eventually dying come first frost.

Where they are native, they have a ton of predators to help with infestation. Unfortunately, they do not have many predators here. The main ones being Praying Mantis, and Spiders. Experts believe, we cannot stop the spread, but we can slow the spread. If you see one, have no mercy and smash them and report the areas in which it was found to your state department of Agriculture. In this way, we can all help protect each other’s crops.

You may have noticed that the summer heat has broken here in Southeast Michigan. With a high of 74° yesterday, and temperatures projected to barely creep into the 80s for the rest of the week, as much as I hate to admit it, autumn is blowing in. And with that breath of fresh air, we start to consider fall planting.

We carry many varieties of crabapple that could be perfect for what your customer is looking for. Weeping, spreading, and upright shapes with pink, red, or white flowers and purple or green leaves can be used to fit beautifully in any landscape. My personal favorites are Coralburst with light pink flowers and the beautiful deep purple/red leaves of Purple Prince, Royal Raindrops, and the new columnar variety Gladiator.

Whatever the need, there is a crabapple for your customer. And here at Christensen’s we’re happy to help you find the perfect one.

I am missing flowers (both literally and emotionally).

How can I work for a plant nursery and have zero blooms in my yard in the middle of summer? (Maybe because I work for a plant nursery?) I get so excited at the beginning of the season with all the pretty things coming in that I take them all home and plant them. Tulips and Daffodils, Hellebores, creeping phlox’s, Dicentra. Stunning. And then what happens? After the blooms fade and the ephemerals die back, I end up with a lot of green. And then… nursery life goes into full swing and by the time I get to slow down and catch my breath, it is mid-summer.

Where is my color? I need plants. Taking a walk through our perennial lot I notice all the plants that are in full sun with beautiful flowers. I want that! Easy choices are the Rudbeckias. Echinaceas, and Hemerocallis. But what are some less obvious selections? My flower beds have some time in the shade, so in order to get the best show of color, I need varieties that can handle both. So, on my walk, I took a few notes.

Geraniums are a good choice. Full sun or part shade, “Rozanne” can be a good rambler. I need to fill in some space and I know she’s about 20” tall by 28” spread. Very low maintenance and long-lasting blooms throughout the whole season can guarantee a nice show of color through these dog days of summer.

Astilbe’s have always been one of my favorites and we offer a wide array of sizes and color. I’m a big fan of their fluffy, showy flowers. Although we have them in full sun, Astilbe’s actually prefer a bit of shade to cool them down after a long hot day.

Our Chelone “Hot Lips” are just about to pop. 2’-3’ feet high and a 1’ spread, these are great to add a backdrop or color to a dull corner. These will be perfect for this time of year! They can grow in drought conditions until established or they can grow in bog or rain gardens. They are low maintenance and will handle the full sun or partial shade.

Heucheras, I think, are going to be a staple. With many varieties to choose from, they are a great, easy way to tie any color combination into the landscape. Different heights and sizes will be perfect to tuck in around the taller plants. And again, heucheras prefer part shade, can handle sun, like it a little dry. Perfect for my needs!

There is a theme here- low maintenance and lots of color!

And finally, ground cover! Of course, some of that “green” in my yard are weeds. Since I really don’t have a lot of time to throw down mulch every year in the spring I’m going to have to plant something. We have lots of choices here at Christensen’s, however, I have found that Lamium is a great choice for spreading. Vigorous but not invasive, the two-toned foliage is striking and can fill in quickly throughout the season. If I was just looking for a colorful addition, I'd go with 'Orchid Frost'. But, I’m thinking the 'White Nancy' may be a great addition to brighten up and throw some definition into the mix.

I now have a few choices. But there are so many more! Seriously, it’s like choosing a paint color. I know if I took another walk through the perennial lot or into the Hosta House I will have a whole new set of plant varieties, colors, and textures to take home and play with! The choices are plentiful!

I’ve been planting a wide variety of nursery stock from the moment I had a yard to plant in. I bought my first home in the 80’s and after ripping out pretty much everything that was there – it was time for a rehab – I started bringing home my favorite plants from our vast inventory here at Christensen’s. That employee discount got QUITE a workout, let me tell you. Sure, there were failures, for example my attempts to grow daphne, oxydendron, and a succession of acer palmatum, but in my mind a dead plant just opens up a spot to plant something new.

However.

There are some plants I NEVER should have planted. They all have one thing in common – aggressive, invasive growth. It’s not an accident that several of them are vines, plus some perennials that spread underground and come up yards away from the perfect spot you chose for it then proceed to colonize the rest of your yard, and the neighbor’s yard, too. Word to the wise – avoid “plant swaps”. There is a reason people have excess to trade.

I didn’t plant any bamboo, luckily, but the Japanese anemone had to come out, as did the Ribbon grass (Phalaris). I didn’t plant the Aegopodium or the Convallaria, but only was ever able to eradicate the Aegopodium as the bed was contained by the concrete drive. We built a giant sieve out of hardware cloth and I dug up the whole bed and got every scrap of root. The Lily-of-the-valley persists to this day among some hosta I transplanted to my new house, wish me luck.

The beautiful Porcelainberry vine I hid behind the garage is probably still sprouting back in spite of repeated attempts with spade and sprayer, and the gigantic Sweet Autumn Clematis that grew to cover the entire shade structure is likely still trying to swallow Plymouth Township. But it sure was pretty and smelled fantastic. But don’t plant one. It’s horrible.

The number one worst plant I ever planted was the Trumpet vine. Fond memories of plucking the orange flowers and tasting the nectar inside (sorry, hummingbirds) from my Grandmother’s yard at the original nursery on Ann Arbor Road gave me the bright idea of planting one in a tiny spot in the side garden of my postage-stamp yard. I even extended the chain-link fence six feet higher to give it a nice trellis to climb on. Visions of hummingbirds filled my imagination, and I figured in a year, maybe two – OK, FINE, three – I’d be a major stop on the hummingbird highway.

Hah.

The seasons passed with not one single flower. Ever. But the VINE? It ran underground and started coming up randomly, all over the yard. Ten, twenty feet away, no problem. Digging it up was futile. It’s immune to Roundup (apparently). I tried to get rid of it for ten years.

I finally moved.

These days the only vines you will catch me planting are Clematis (which randomly die for no good reason) and Hydrangea petiolaris, which is always well-behaved. A mature one came with my new house, and when the tree it was climbing on died, we left most of the trunk standing, because nobody messes with my Climbing Hydrangea. You really should plant that one.

By now, you probably know that we have a landscape lighting division here at Christensen’s. We currently stock 2 product lines (Sollos and Alliance) on our shelves at the Hardscape Center, and we have a very good selection of materials available. Now with that being said, it is VERY difficult to stock every single fixture in every single size that is produced, let alone with the multiple color options available. Getting into LED lamps is an entirely different animal. With LEDs, there are multiple beam spreads, color temperatures, and bases. While Sollos and Alliance are bipin based, we do stock a few wedge base lamps if you have to swap them out from another product line. We try to save you some time instead of bouncing all over town!

There are a few new fixtures on the market, but we are not currently stocking them quite yet.  They are readily available by special order.

Alliance Bollard100-LED. Dominating in its appearance, this fixture is outstanding for commercial settings or for areas where a standard path fixture with a ground stake may not be sufficient. Standing at an impressive 36” tall when completely assembled, The Bollard100-LED makes an impressive statement when installed correctly. Watch the video above from Alliance for their recommended installation process.

Seems like there are always new fixture designs on the horizon, so be sure to check with us often for the latest updates!

Barbecue chicken and ice-cold lemonade, cold beers and brats, chilled watermelon and grilled hamburgers. That was a small part of my menu for the fourth of July weekend. I most definitely took advantage of some choice weather and time off to relax and recharge. My outdoor toys and appliances however, had no rest. They had 8+ children and friends to keep refreshed, full and entertained. The hose had a good workout, too!

But after the cooking and entertainment have concluded, the cleaning must begin. And unlike cleaning the kids, I would not recommend using the hose to undertake this process. Here are some maintenance and cleaning tips to help keep your outdoor appliances looking new and clean. 

Grills Are Not Self-Cleaning

It’s easy to fall into the habit of just giving your grill grates a quick swipe with a wire brush before you toss on those steaks. While you won’t directly harm your grill by doing that, it is important to check its other components, specifically burners, valves, and hoses. If you have a gas grill, don’t ignore the burners. Use a stiff brush periodically to clear grease and gunk away from them, and as you cook, pay attention to the color of the flame. A healthy flame on a gas grill should be blue with a yellow tip—if your flames are all yellow, turn off the grill and disconnect the fuel tank so that you can check the fuel valve pressure. Lastly, look at any hoses, such as fuel lines, on the grill. Even if your outdoor kitchen isn’t directly exposed to the elements, it is still affected by temperature changes. Depending on the material, grill hoses can contract and expand in response to changing seasons, so give them a brief inspection to see if any of them have cracked or split and need to be replaced. 

Don’t Go Nuts Cleaning Outdoor Appliances 

Stainless steel appliances are extremely popular in outdoor kitchens, and for good reason. Not only does stainless steel look nice with the hardware typically used in outdoor spaces, but it is also resistant to rust and corrosion, making it ideal for outside use. Although stainless steel is a durable material, it isn’t indestructible. Don’t cut directly on a stainless-steel surface, only use a cutting board. Hot pots and pans as well as other metal, steel, or cast-iron items can cause staining and corrosion if they’re left on a stainless steel surface for too long, so find another resting place for them or use a heat resistant pad or cloth. A rinse with soapy water will be sufficient for cleaning a stainless steel surface, but make sure that you follow the grain of the metal and dry it completely. There’s no need to use chemical cleaners and stay away from steel wool pads; little bits of them can flake off and get imbedded in your stainless steel surface. While the actual surface won’t rust in that situation, the steel wool pieces will. 

Protect Your Outdoor Furniture 

While it may not be the first thing to come to mind when you think of outdoor kitchens, furniture plays an important part in rounding out your backyard sanctuary. If possible, try to keep your outdoor kitchen furniture out of rain and extreme weather by bringing it indoors. If that is not an option, try looking for vinyl covers that don’t touch the floor, which allows moisture to escape. You can clean vinyl, mesh, and fabric components with a mild, all-purpose cleaner. Avoid harsh bleach or ammonia-based cleaners, they are not necessary and can do more harm than good. As with your countertops, try to catch and wipe up spills as soon as possible. 

Check Your Fridge 

Did you know that there are 2 different ratings for outdoor refrigerators? The better option is an actual “Outdoor Rated” refrigerator. It differs from the “Standard Outdoor” by having 304 stainless steel material, greater insulation, an advanced compressor, and better ventilation. This will help when the outdoor temps start to climb in the 90’s. Keep your fridge full, even if it is just water bottles. This will help the fridge work less and keep your items colder. 

Your outdoor kitchen and fireplace area represents not only a financial investment, but also a commitment to time spent with family and friends. Taking a few minutes to maintain your outdoor kitchen, patio, and furniture will protect your investment and allow you to spend as much quality time as possible with your loved ones.  

A Boxwood Revolution! 

Have you heard about the two NewGen® boxwood that have come onto the market? 'Independence' and 'Freedom' came out recently and are a fresh breeze of improved genetics in the Buxus arena. They have a strong tolerance to boxwood blight and are resistant to leaf miner. Both are considered zone 5-8.

With both of these being relatively new to the market finding any that are larger than a #3 is difficult. But with more time and a few more growing seasons, I am sure we will start seeing larger plants available. At this time, we do not stock any of these at Christensen’s Plant Center but can special order them for you. I am looking at bringing some in for next spring and just wanted to make you aware of these new beautiful boxwood that are coming soon.

Christensen’s Plant Center has a wide range of departments. One of them being the Perennial Department. Known to most as “The Perennial Girls”, we are the group that receives, grows, and maintains the stunning perennials you see around the nursery. This includes the beautiful material on the Perennial Lot, roses, grasses, and more! I'd like to introduce you to the Perennial production department, and all that goes into ensuring you have the best possible perennials to meet your landscape needs.

Some of you may not know, but as well as bringing in perennials fully grown plants off trucks, some of the perennials you find around the nursery are produced right here on our property. Our “west” location has greenhouses that switch over from winter storage to perennial production as the weather breaks. Spring is our busiest time. We spend our weeks potting up as much as possible, so that come summer, we have plenty of dazzling product. We grow a wide range of perennials, grasses, and even some shrubs. This spring, we even potted up some Boxwood varieties with big hope for success!

Soil mixes (which have been trialed over time), pot sizes and types, and water needs are all things taken into consideration in the production department. Hemerocallis Stella, Hosta Patriot, Heuchera Palace Purple, and Nepeta Walkers Low are all production favorites. These staples are always growing in production as a backstock to ensure that we always have some on hand. With the inventory shortages industry wide, this back stock can also come in handy when large quantities are unexpectedly needed.

Aside from the staples, we also grow some specialty items such as Peony, Dianthus, and other “funky” varieties. These diverse items are some that we have trialed over time and have proven to do well with. Being able to provide what is needed as availabilities change, is a huge benefit to the Production team!

Perennial production is a flexible department, that can adjust to both industry and customer needs. We work hard to grow and maintain our perennials to ensure that we have a fabulous product year-round! Head over to the “Perennial Girls” for all your perennial questions and needs. 

Is this a trick question? Not really. Every year, in mid to late spring, turtles start to move. The males are looking for partners and the females are looking for a good place to make a nest for their eggs. Unfortunately for a lot of them, this means crossing busy roads and a lot of them don’t make it. Sun-warmed pavement and sandy road edges combine to attract these tiny travelers so look sharp as you drive – what might look like a rock in the roadway ahead could well be a turtle trying to cross.

Michigan is home to about ten species of turtles, nine native and one introduced. The most common one is probably the pretty painted turtle, and most of us have seen a snapping turtle. We also have musk turtles, map turtles, spiny soft-shell turtles, spotted turtles, and the introduced red-eared slider. Three of our turtles are quite rare and if you’ve seen one, congratulations! They are the wood turtle, the Blanding’s turtle, and the Eastern box turtle.

My pond is home to a small colony of painted turtles and two summers ago there was a pretty big snapper, but I think she has moved on. I’ve found turtles in the yard trying to dig a nest for eggs a couple of times, but I have yet to find any baby turtles of any species. A shocking number of nests are dug up and the eggs are eaten by raccoons and other animals, often just days after being laid. A lot of animals eat baby turtles, too. It can take 20 years for a turtle to get old enough to breed so if I see one trying to cross a road you can bet I am going to pull over and try to help it.

If you do try to help a turtle cross a road, always carry it in the same direction it was heading, and set it as far off the road as you can, 10 or 15 yards if possible. Never lift a turtle by it’s tail, and don’t be tempted to move it to another location – they know where they live and can be killed trying to get back home.

Locally to me is the University of Michigan Edwin S. George Reserve, a fenced 1300 acres where researchers are studying the endangered Blanding’s turtle. Because they have been able to tag individual animals, they have been able to age one particular female as 83 years old (in 2016). I have been lucky enough to have seen a Blanding’s come through my yard and it’s a thrill every time. Now if only I can find a box turtle someday I can die happy.
