I like to call this time of year ‘the season of anticipation.’ Over the years, as I’ve developed my patience, I have come to enjoy the sweet ache of waiting. My son, on the other hand, is in anguish waiting for each holiday to arrive, starting with Halloween. And after each one is over in the blink of an eye, he’ll be in anguish until the next one arrives.  

Of course, I have been trying to teach him the value of waiting. We've defined "patience" as "waiting with a good attitude" in our family.  If you ask him what patience is, he'll use that exact quote with an eye-roll and sing-song voice... which is sort of the opposite of the definition. 

In true childhood fashion, the lesson didn’t really sink in until his teacher had them plant seeds and they watched them germinate in a clear cup. He dutifully informed me that, “Even though you can’t see it, the seeds are working hard underneath the ground, taking up nutrients and growing roots.” I told him that the holidays were the same thing. Even though he couldn’t see it, Mom and his family were working hard to prepare for the events. He scowled and ran off.

Nothing in horticulture elicits more anticipation than bulbs. As so many aspects of our life have sped up (I blame online shopping), nature continues to keep her own time. And, for me, there’s something reassuring in having to patiently wait for an investment into the landscape. I’m sure for you, as landscape professionals, bulbs can be a hard sell in a “Want-It-Now” culture.

But the reward of early spring blooms in multiple colors and forms is something that everyone loves. This time of year, it’s important to communicate with your customers about the benefits of planting spring bulbs now.

Come in and see the many options we offer. Take pictures to share with your customers. I love our “wall of bulbs”. It’s a wonderful way to see and choose your favorites. This beautiful and tempting full rack of color is the reason I purchased way more bulbs than I can plant by myself. Fortunately, I have a ready supply of labor because my son has become very excited about planting. Of course, once we plant our tulips, daffodils and allium, I’m sure he’ll be in anguish for spring.

Growing and caring for plants is my passion. As if growing tens of thousands of perennials a year here at Christensen’s Plant Center wasn’t enough, I have taken my love for plants home with me. I currently have 20+ houseplants that I care for. The key to success is knowledge and experience. It is important to know what to do, and what not to do. Proper plant care will ensure that your plants thrive, and do not suffer or die (my death count is quite impressive). It has taken years of trial and error to figure out what works best, but I am still learning. If you have any interest in becoming a houseplant novice, this article will provide tips, suggestions, and things to consider.

Houseplants have different demands, requiring individual watering, sunlight, and soil needs. You will want to know each plant’s distinct needs when choosing what to grow. I recommend starting with easy-to-grow houseplants and then move up in skill level from there. My favorite plants to grow are Pothos varieties. These are vining plants that can get very long. Once they get lengthy, they can be “chopped and propped” which means they can be cut into pieces for propagation. To propagate, I cut off a 3-4” piece right below a leaf node (where the leaf meets a stem), place in water, and watch them root. Once rooted, I place them in a pot of soil, fertilize, and watch as they take off. The ability to propagate is one of my favorite features of these plants. Pothos, Snake Plants, Bamboo, Peace Lily, and Spider Plants are among the easiest to grow. While Orchids, Ferns, Fiddle Leaf Fig, Succulents (like string of pearls), and air plants are among the most challenging. Consider how much time, and effort you have and are willing to give to plants at home when deciding what to plant.

Another factor to consider when growing houseplants is watering needs. Some plants can be watered once a week, while others would prefer once a month (or when soil dries out completely). I also like to water my plants on a schedule and mark it on my calendar. I always check the dampness of soil with my finger before adding more water. Overwatering is an easy way to kill houseplants, succulents especially.

Growing houseplants is beneficial to mental and physical health, air quality, productivity, connectedness to nature, and is aesthetically pleasing as home décor. For these reasons, I highly recommend growing and enjoying houseplants in your space. This hobby is something that keeps me happy and busy, and maybe you will enjoy it too.

**Authors note: Husbands/wives/partners/roommates etc. are not always as enthusiastic as you are about turning your home into a jungle. Please keep that in mind when trying to fill every space available with houseplants. Be sure to use the above benefits to try to persuade them! However, compromise might be necessary.
HAPPY PLANTING!!

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.

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.

Walking around Christensen’s this spring you may notice a few distinct differences from previous years. You may see our new signs or the new machines at the hardscape center. However, the difference I am talking about is nothing new at all, it is nothing. The most obvious change for many of us is the half-empty field and the lack of towering evergreens waiting in our yard. As our investor for Deciduous, Ornamental, and Evergreen Trees I have been looking across the country for this material and the simple answer is that it just does not exist in many cases.

Arborvitae are experiencing an exceptionally brutal year on the east and west coast. After severe drought hit the west coast last spring and summer fires started burning across Oregon. We were being sent images of entire fields turned brown due to a lack of rain in what is historically one of the wettest regions in the country. Further east in Tennessee certain varieties of arborvitae have been hit by a yet to be identified disease. Paired with the unusually wet spring they have experienced and high demand these plants are not as readily available in large sizes (7-8’) as they once were. We have been buying up as much as we can stock due to the unpredictability of this crop.  Currently, we are overstocked in 4-5-6’ Emerald Green and have placed them on sale, but it’s hard to say what will continue to happen throughout this season with this genus.

Red Flowering Cherokee Dogwood are experiencing a similar issue. These trees are particularly susceptible to damage from excessive water, but also fungus and mold which thrive in wet conditions. Tennessee’s wet spring has resulted in crop failures and a lack of available material.

These droughts and diseases only account for a small part of the shortages, but they do contribute to the problem.  As we’ve mentioned before, the real disease behind the shortage is the pandemic we have all been living through. In addition to the increased desire to landscape, everyone sitting at home also pointed us towards a recession which was combated with a huge drop in interest rates. This created a boom in the housing market. Now demand for plants was not only surging for renovation but also for new housing developments.

This new housing boom is the largest our country has seen since well before the market crashed in 2008. As we mentioned in Eric’s article, Bring On Spring, trees take 5-10 years to size up, and 5-10 years ago we were on the back end of a huge recession. Due to financial difficulties, planting heavily to plan for the next demand surge was not an option. Pulling ahead on smaller and smaller crops starting in 2020 caused size shortages. This “overselling” is most obvious with evergreens, most large sizes are not available because they have all been sold as smaller trees in previous years.

So here we are in 2022, available product on many popular varieties is down to 6’ and 2” trees. As long as demand stays high, and everyone keeps selling, the next year’s available material will be smaller and smaller. And while the economy is slowing down, historically, an increase in fuel prices drives down vacations and increases investments in homes for “staycations.” If fuel costs stay high, we may be looking at yet another season of homeowners pouring financial resources into their landscapes.

Unfortunately, there are no real substitutes for pine, spruce, and arborvitae but there are some options. While larger sizes of popular varieties such as Emerald Green and Green Giant Arborvitae are harder to come by, similar varieties can be easier to find. We have good quantities of Hetz Wintergreen Arborvitae available which work great as a narrow evergreen and for screening. If you can substitute smaller sizes, check out the Emerald Green Arborvitae sale (see Sticks & Stones e-mail). Crabapples or Pink Dogwoods work as a bright flowering substitute for red flowering Cherokee Dogwoods. Many growers we have spoken with have learned from this unprecedented situation the industry is in. They are planting as much as they can to try and keep up, but it could be 5 years before we see a full recovery.

We’ll continue to keep scouring our sources to keep you supplied with the best plant material as long as this landscaping boom keeps going.

Over the past three years, the green industry in Michigan, and indeed the country, has been on a high. But that high has come at a price, and that price has been our supply pipeline. The media has spent the past many months talking about supply chain woes. Anyone that has bought a car recently knows. Our supply chain woes have been slow in coming, and, regrettably, will be slow to reseed as well.

Growers in the nursery industry have spent the last three years trying to keep up with almost unprecedented demand. Unfortunately, our products take significant time to come to market; time that the growers have not had. Since an 8’ tall spruce takes almost 10 years to come to harvest, growers have done the only thing they could do to keep up with demand, which is to sell material early. In 2019, landscapes consumed some of the material slated for 2020 projects. In 2020, landscapes consumed all of that year's crop, and a large part of 2021’s crop, compensating for what was used for 2019 and covering the increase in sales. In 2021, the cycle repeated itself. 

Now we find ourselves in 2022, and there is nothing left to steal. Growers find themselves selling smaller and smaller plant material as landscapers accept smaller sizes to fill a planting. This does not allow for the filling of the pipeline with larger material, as it is all sold in a smaller size. 

With our product that takes between a few months to a decade to produce, the refill will be slow. 

Christensen’s will be a landscaper’s best friend as we navigate this supply issue. We are in constant contact with growers all over the country sourcing material. Our relationships allow us access to material often before it is published on an availability. Please use this resource! Let us use our reach instead of you spending hours trying to get answers.

Christensen’s Plant and Hardscape Centers is honored to be the resource for the landscape industry in southern Michigan. The relationship we have with you drives us every day to make sure that we are doing everything we can. And this year is no different. 

As I write this, I am watching our yard operations crew unload yet another load of trees. With the first trucks of the year arriving in mid-February, we continue our preparations for the 2022 landscape season. Plants and hardscape materials will continue to roll into our yard. I encourage you to use our 91 years of experience.

When I was growing up my father and I planted gladiolus corms in our flower garden next to the house. I remember their bold colors reliably displaying each summer. When I moved into my own home years later I found all sorts of new and exciting colors available. They were beautiful that first year, but the following year I noticed that most of my glads didn’t come back. After some internet-sleuthing I realized that they are supposed to be lifted and stored inside for the winter. So why did they always come back when I was a kid?

Microclimate perhaps? Our main flower garden was against a south-facing brick wall, with years of compost mixed into our sandy soil. Glads don’t like a wet bum, so our native, well-drained soil was a good match. The sun-exposed brick wall warmed up the soil, tempering the chilly winter ground.

Could it have been the heirloom varieties we grew? I’m generally a believer that local heritage varieties are hardier. This seems to be the case with gladiolus. In my experience the new fancy ones, though beautiful, are hit-or-miss with successfully overwintering in our area.

Here are some tips to help you on your way to beautiful spires of color each year:

Plant in pots

Be sure your pots are large and heavy enough so the flowers won’t blow over, also make sure they have drainage holes. Add rocks to the bottom of the pot, top with a sandy soil mix. For an extended blooming season plant pots a couple weeks apart, or mix varieties in the same pot. You can add supports to help the spires stand up as they grow tall. There are shorter, and even dwarf varieties available that may work well in pots without support or the fear of wind damage on balconies. After the flowers are spent it could be a good time to move the pots somewhere less conspicuous, as the plant does not rebloom. Sometime before the first frost, dump out the pots and collect the corms, set them somewhere where they can dry in the open air for a couple days, then lightly cover them up to dry further. For final long-term winter storage place them loosely in layers in a cardboard box, separating layers with newspaper. Keep them in a cool dark place where they may nap until spring, protected from animals and sub-40f temperatures.

Leave ‘em in the ground

With a little bit of luck and some forethought you can have success simply leaving your glads in the ground! Moisture and extreme cold temperatures are what you’re trying to manage. To this end, I have found that digging trenches in sunny areas that are not prone to spring puddling works out well. Planting next to a sun-exposed wall is even better! Dig the trench about 14” deep and fill the bottom 3” with rocks. Mix some native soil with whatever amendments are needed to build a sand-heavy blend with a modest amount of organic matter. Plant the corms at various depths as you fill the trench with soil. I’ve sunk ‘em down 8” with no problems. Hardier varieties such as ‘Violet Queen’ and ‘Atom’, as well as many old heritage classics may help you gain an edge on the colder weather.

Glads will do well with a mulch covering the soil and a balanced fertilizer after emergence.

How's everyone doing? I think we are now past the worst of the summer heat but to be honest I was ready for fall weeks ago. We may like to complain about the weather but when you are out in the hot burning sun day after day I think it's justified. Congratulations on making it through the dog days! Labor Day is the traditional end of summer but you and I both know there will be weeks of beautiful - even hot - weather before we trade sunscreen and Gatorade for hoodies and Carhartts. But today, let's get out of the sun for a minute and do some shade gardening.

I'm a big fan of shade gardening, and the plants that thrive in shade and partial shade. I used to have an enormous Hosta collection but now that I am gardening in the country I had to scale back on those because they are basically expensive entrées for our hordes of deer. I keep a few favorites behind fences but out in the yard I have better luck with ferns. 

Lest you think that all ferns need daylong shade, I have quite a colony of Ostrich fern that do just fine in nearly full sun. In fact they were getting a little carried away so I had to take some of them out. Here they are happily crushing my baptisia.

You're going to need to provide supplemental water especially under big trees, but established ferns can be surprisingly drought tolerant. Maidenhair fern can be a little fussy but Autumn, Lady, Male and Cinnamon fern are all happy in part sun to full shade, which is also where you will find ME when it's 90° or better. And you should really try to have some Painted fern if at all possible. 

So let's take a break from summer heat and enjoy this word search puzzle created by our very own Jeff Good. (Answers here)
