As I write this, hurricane Laura is ashore in the gulf. In a matter of days, the remnants of this storm will most likely be bringing us some much-needed rain. (Hopefully only rain!)

This event coincides with the start of the last push for the landscape season here in Michigan. With this last push, I wanted to take a moment to remind all our contractors of the need to order all material as far in advance as possible to ensure a successful project.

All material has been moving very quickly this year. Projects are abundant, and we have been blessed with a prosperous economy. However, this has led to issues with availability across the board for landscape materials. This coupled with the coming push for the end of the landscape season is why I am issuing this storm warning.

• Place orders for EVERYTHING in advance!! Do not assume that we, or any other supplier, will “always have it in stock”. 

• Take nothing for granted. Plant material is starting to run thin, and growers are struggling with labor. (H2A/H2B program issues, etc.)

• Hardscape material is showing very long backlogs due to the early spring shutdowns. Many manufacturers have announced several products or lines that will no longer be made at all this year, and other products can have up to six-week lead times.

So please heed this storm warning. Place your orders early to make sure that your projects continue on smoothly for the rest of the year.

These days I have a forty-minute commute to work, and I enjoy the progression of bloom through the season, of everything from landscape ornamentals to woodlots and farm fields. There is always something happening. There are some plants I would like to see less of, though.

In late May the purple, white and pink flowers of Hesperis matronalis, aka Dame's Rocket, bloom in abundance all up and down the roadsides and into fields and woodland edges. I love it, and I don't - it's invasive, having long ago escaped into the wild. It sows itself with abandon, soon forming vast colonies that crowd out and replace native plants. Related to Garlic Mustard, it spreads just as aggressively. If you like the look I would steer you to the tall phloxes, like P. paniculata or P. divaricata because we do not need any more of this plant. Don't get me started on Garlic Mustard, it's not even pretty.

But who says invasive plants *have* to be ugly? Here's another one that is a common sight in Michigan, Hemerocallis fulva, aka Ditch Lily. It's not a true lily, but a daylily, and not a neat clump-forming one, either. No, it spreads by rhizomes and forms large colonies filling the ditches on either side of roads all over the state. I like seeing the cheery orange flowers every summer but again, it's busily crowding out native plants. 'Kwanso' is a double form that is offered in the trade, it is not nearly as aggressive. 

One of the worst offenders is the notorious Lythrum salicaria, aka Purple Loosestrife. In spite of decades of trying to knock it back, by physical removal and the introduction of several species of beetle that eat it, it still occupies acres and acres of wetlands across the entire continent. None of our native animals or insects really need it for either food or shelter and I am personally over the obnoxious color of the flowers, too, because they just remind me of the futility of trying to put the Genie back into the bottle.

There was talk at one time that some of the named varieties were sterile or nearly so, but it turns out that they breed just fine with the wild ones. So even if you find it for sale, don't plant it. If you have it on your property, get rid of it. 

There are loads of invasive plants loose in Michigan, from Autumn Olive to Phragmites, Buckthorn to Spotted Knapweed, Multiflora Rose and Oriental bittersweet, to the honeysuckles - oh, boy, the honeysuckles... To all of them I say, hit the road!

In all bad things, there is good.

COVID-19 has caused havoc in many industries. It has closed many businesses, some never to reopen. Covid has sickened people and some have died from the illness. This is the bad.

Here is the good for the Green Industry:

• People were forced to stay home so they improved their homes
• Money issues were mitigated by a $1200 stimulus payment
• Businesses utilized the Payroll Protection Plan to keep their employees working
• The unemployed received $600 weekly from the federal government
• State unemployment checks continued to be paid
• Many people planted a vegetable garden for the first time or the first time in years
• Less travel meant fewer expenses for fuel, auto insurance
• Vacations were postponed or cancelled so with time and money available home living conditions were improved
• Landscaping and gardening are not impacted by crowds or social distancing
• Landscapers are remarkably busy because of limited staffs, no immigrant workers
• There is pent up demand within the green industry to hire additional staff

So what does the future hold for the Green Industry?

Here’s my view thru a slightly cracked crystal ball:

• Working from home will stay with us into the future
• Zoom meetings will replace much business travel
• Education will transition from the classroom to ??????
• Plants will occupy more of people's time and attention
• Embrace the change - it is happening!

There are so many options when adding lighting to your jobs - wash a wall with bullets, illuminate a path with tall hats, put ledge lights under the steps… but don't forget to look UP. Lighting draws one’s interest to noticing foliage, angles, and shadows. Fountains shimmer, boulders come alive, then one becomes entranced following the craggy trunk of a tree up into the branches.

Anyone can install outdoor lighting, but a truly captivating design that incorporates three dimensions is what's going to sell the project and have the neighbors asking for business cards.

Here’s how: Step back and look at the entire project area. Stand at the road or across it and observe the features of the home and landscape. You may want to note a few lines of sight to areas of focus such as porch pillars, dark corners, or structural trees. Also note the impact of existing light sources on the property and from neighboring homes or street lights. I like to take a screen shot from the satellite map on my phone to draw sight lines, then use the highlighter tool for light coverage areas, using different colors for existing and prospective.

After you have your general ideas plotted, move in closer. Where does the dog run and kids play? Where will people be sitting or cars be parked? Ask the customer how they plan to use the space. The more you are able to plan ahead, as with any job, the greater efficiency you'll have.

For seating areas, as fun as shadow charades may be, you don't want people irritated by a light in their eyes or to have a flood light-washed façade disrupted by a car parked close to the house. Most light fixtures stick up out of the ground, so placement is critical to avoid trip hazards. To highlight a tree trunk select a tight 10-15° beam spread. For more branches use a wider, more flood-like 30-40° pattern.

Bullet fixtures can target a specific object or be used farther away to illuminate a broader area. To really flood an area with light, a Sollos FRF058 or Alliance BL300 will do the trick. Pillars can have wall sconces like the WS200, and those confident to stray off of the instruction sheet can even mount a fixture up in a tree! Ask someone in our Hardscape building how to put a "tree loop" in your wiring so the installation will last as the tree grows.

Other options include lower profile well lights and in-ground fixtures, hanging fixtures, even rolls of tape lights. Check out Alliance's new line of color changing bluetooth fixtures for a customizable show-stopping display! With these new lights, a homeowner can change color for each season and show off to their friends as they slid their thumb around on their phone, changing the lights on a whim.

The possibilities are as endless as your imagination. Search online for inspirational photos and videos or ask the sales team at Christensen's, "What can I do that's different?" In landscaping, our projects can keep us looking down at our work, but please, don't lose sight of what's UP!

There is an amazing Mexican restaurant by my house that I love, especially since they have a nice outdoor patio with tables. I sit down, and wait for the waiter to come take my order. While I wait, I shift my weight from one side to the other, trying to find the spot where the chair doesn’t wobble. Then the waiter brings my beverage, and while managing my chair I now have to contend with the table that keeps moving back and forth. Then the meal shows up, and by now it looks like I’m having convulsions! It’s one of my pet peeves, and I wind up putting a piece of napkin under the chair, the table, or both to keep me less annoyed. Now you know why I ask for extra napkins!

All napkins aside, outdoor patios and living areas are amazing spaces to enjoy more time outdoors. Some things to consider however, might be what you want to do in these spaces. Many styles of tables and chairs need flat surfaces to be stable and secure. Beyond the wobble, cobbled surfaces may be harder to clean or show dirt and stains more prominently. The high peaks in a cobble style paver may also wear faster and show signs of aging more quickly than the lower parts. Aesthetically, the textured product looks great, but its functionality may suffer.

Many paver manufacturers have a similar product line with smooth finishes. They offer the same large format size and similar colors, but with table and chair-friendly surfaces. Some of the color blending can make them appear to have texture. The smooth surfaces will be much easier to have stable tables and chairs, but also help with planters and outdoor rugs and mats. Smooth surfaces are also easier on your feet, so when you have a slow roast BBQ or chicken that takes some time to cook, your feet will thank you.

From a design aspect, the smooth texture can also give you a much larger array of banding and bordering options. Having some texture in a soldier or sailor course will add some extra pop next to a flat surface. From an installation aspect, the smooth is easier to install sweeping sands and apply sealers. The products install the same, so there is no need for extra training. These products offer more possibilities without hindrances. I call that a win-win!

I have been working in the industry a long time, and I have come to look at some plants as... lonely. Lonely maybe isn’t the word, but underappreciated isn't the correct word either. The sparkling Stellas and Endless Summers of the world are not lonely plants. Even plants like Clethra and Fothergilla are not lonely plants.

I do think of all Ilex as lonely but I think of the verticillatas - Michigan Holly - as the loneliest. They seem lonelier than glabras (Inkberry) for some reason. Unlike their loved big brothers who are evergreen with classic holly leaves, the verticillatas are considered old fashioned and without much flair. BUT LET ME TELL YOU! There are some new cultivars and hybrids on the market, and they will make you wish all Ilex were deciduous because, “The berries are where it’s AT!”

The older varieties like  ‘Winter Red’ and ‘Sparkleberry‘ are awesome when the leaves drop and the best berry display is in view. But these older varieties can get a little leggy and out of control if they are not maintained. The older cultivars also have men in their lives that get unruly after a while - go figure!

There are several breeding programs that excite me.

• Berry Poppins®: How about heavy berries, (read COPIOUS) on a 4' tall dwarf plant, perfectly sized for the landscape. The berries are large and an orange-red in color. The leaves also drop a little earlier than other hollies for a longer display. The pollinator is... are you ready? Mr. Poppins®. 

• Berry Heavy® Red: bred for better bearing (copious again) and even longer persistence. The berries are bright red and nicely bunched along the stem. This one will reach 6-8’ in height. The pollinator is again, Mr. Poppins®. (He does get around, along with his friend 'Jim Dandy' who can help out with the pollination duties.) There is also a gold-berried version, Berry Heavy® Gold.

• Little Goblin® Red: this is a 4’ dwarf with extra-large red berries. Her pollinator is Little Goblin® Guy. There is also a orange berried variety in the Goblin series.

We are not always appreciative of new plants. Does that make them lonely? My opinion on these plants is that anything to bring the poor Michigan Holly into the spotlight is good. But I have also been watching these new varieties for a couple of years now and these are good plants and a welcome addition.

P.S. Part two may be on all the cool and awesome new Inkberry cultivars...

Some plantings are difficult.  Poor soil, deer, high ph, lack of irrigation, or a combination of some or all of these issues.  The more factors in combination, the more your plant list gets whittled down.  One of the plants you can count on to be available to use when the whittling is done is diervilla, or bush honeysuckle.

Diervilla grow in most soil conditions, all light conditions, and are deer and drought resistant. They all sport somewhat inconspicuous yellow flowers. The Kodiak® series, developed for the landscape, sport various leaf colors for more summer interest and are non invasive.  All of these colors, including amazing fall colors, are more intense the more sunlight the plant gets.

Kodiak® Black sports a blackish-purple leaf which contrasts well with the usually inconspicuous flowers.  Kodiak® Orange and Red are also available with hints of orange and red in the leaves.  The most intense fall color seems to come from Kodiak® Orange. 

These plants get between three and four feet tall and wide.  Their habit can be considered a little messy and leggy if left to grow naturally.  I like to prune them regularly to maintain a smaller size and encourage increased branching, but do it in late fall so as not to miss any of the fall color show. 

Diervilla is a tough plant for tough conditions, but the Kodiak® series gives you an attractive plant even when conditions aren't tough.

My parents instilled in my family a sense of stewardship over nature that has stuck with me through the years. As we grew up in Northern Michigan, we were taught to recycle, use our grandmother’s compost pile, and practice "Leave No Trace" camping and hiking.

As an adult I’ve tried to expand on these lessons to be as Earth-friendly as I can in the current day and age. I keep my water bottle on me to eliminate the need for single use cups, I’ve found ways to reduce my carbon footprint, and I try to support sustainable businesses.

All of these things help, but the biggest way to help the environment are the three R’s: Reduce, Reuse, and Recycle.

The first R: Reduce. This one is probably the easiest to accomplish. There are so many ways to reduce the amount of waste that your household produces. Single-use plastics are the biggest household pollutant worldwide. Reusable sandwich bags and storage containers are an easy and affordable way to cut back on single use plastics. Even just bringing reusable shopping bags to the grocery store can help cut down on the roughly 1.8 billion plastic bags that are disposed of each WEEK in the United States. Keep in mind though, that just like other reusable storage, reusable grocery bags do need to be washed regularly. Swapping out beeswax wraps for plastic wrap is another great way to cut down on single-use plastics.

The second R: Reuse. Keeping and reusing things like boxes and gift bags is a great way to prevent waste. I also like to save glass jars from foods that have been used up. If you soak the labels off and wash them out, they’re great for holding pantry staples like coffee beans, rice, and dried beans. Glass jars also work great as small planters; line the bottom with lava rocks or gravel for drainage before filling up with potting soil and go for it! Another simple way to reuse things is taking old t shirts with rips or stains and cutting them up to make rags for cleaning and dusting.

The third R: Recycle. Recycling may seem like the easiest thing on this list, but many municipalities have stringent guidelines for what can and cannot be recycled which aren’t always clear. I live in the city of Detroit, which doesn’t necessarily have a citywide recycling program. Now as I have to sort and take my recyclables to a processing plant myself there are a few things to remember. First of all, any cardboard or paper that has food on it cannot be recycled. The same goes for containers that have not been thoroughly cleaned out. The most commonly recycled plastics are plastics #1, #2, #4, #5, #6, and #7, so make sure you check the numbers before blindly throwing things into the bin! The biggest lessons here are to check your local guidelines before trying to recycle things.

Working as we do in the Green Industry makes us a natural fit for modeling environmentally-friendly practices both at work and at home. Our families, clients, neighbors and friends can be positivly influenced by our example.

Social Distancing for... plants? Yes, you read that right.

Social distancing for plants has two distinct applications.

The first is to keep plants apart that simply don’t get along well. Examples include those affected by Cedar-Apple Rust such as crabs, hawthorn, and quince and their alternate hosts of Juniper (virginana, horizontalis, and scopulorum). The deciduous get orange spots on their leaves and early leaf droppage while junipers get galls. Similar to this is Pear Rust which affects our ornamental Asian Pears , Bradford, Cleveland, et al. This, too, is caused by over-planting and proximity to Juniper species. The results are similar to Cedar-Apple Rust. A more recent fungal problem exist with our boxwoods and pachysandra. While not alternating hosts, plantings of these as complementary may increase risk of Boxwood Blight. Some genera simply need some distance or even not being included in the same landscape altogether.

The second application of plant distancing is proper spacing. This requires planning and knowledge of plant size, growth rates, and growth habit. The first crime in planting I would call the model home or interior-decorator syndrome. The landscape is planted for the here and now. It has to look lush and lived-in – NOW. The result in a few years is usually a crowded, jungle-like landscape. Much of the original plant material will need to be pulled out. The second crime is a planting that looks nice but really does not reflect the true growth habit of what has been incorporated into the landscape. Remember the Colorado Blue Spruce on the corner of the house; thirty years later you cannot see the house. The development of columnar trees and evergreens has solved this problem. Also, the introduction of many dwarf or compact versions of the old standby varieties has expanded the pool of variety and color palette. Only people my age remember the old Vanicek Weigela (a monster) that yielded to W. fl. ‘Red Prince.’ And now, we have Weigela florida: ‘Wine and Roses, Fine Wine, Dark Horse, My Monet, et al.’ How small can they get?

The art and discipline of plant spacing depends on a great knowledge of plant growth rate and maintainable size. If a new landscape is developing nicely in about three to five years, then you did a good job of placement. Larger trees and evergreens can take around three years to really establish. This is evidenced by greatly increased leaf size and improved coloring in evergreens. From this point on you should see an increase in growth rate. Most woody ornamentals are filling in and exhibit much heavier blooms during this same time. Perennials and groundcovers establish showing very little top growth first season – the Iceberg Effect (roots first, then foliage and flowering the next season).

We are at the mercy of tag information which is far from perfect and landscape architectural drawings rendered by an industry with low plant knowledge. If you take your landscape installation seriously and are interested in long-term results, become familiar with nursery varieties as fast as you can and keep up with new introductions.

Welcome to summer! This time every year we find ourselves having the same conversation with lots of drivers picking up plant material.

This conversation revolves around putting a tarp over their load of plant material. There are two typical answers for this. “I forgot a tarp” or “I am only going a few miles.”

To be honest, we have a chuckle at both of these answers, and the reason for the chuckle is quite simple.

In the case of “I forgot”, we generally know what most of the nursery tarp inventory for most of our customers looks like as we see them often. This also means we know how many tarps the company owns. My favorite “I forgot” comes from a good friend of mine. I sold him a new tarp multiple times when he forgot. And every time he was mad as he knew there were about twenty tarps sitting unused at his shop.

The latter, “I am only going a few miles”, is not so funny. During summer temperatures, damage to the foliage while driving down the road at 50 mph (or more) happens in just a few miles. So really, any driving with the plant material un-tarped will damage the plant.

Here is the beg from Christensen’s. Please tarp everything when you leave our nursery. We will help you tarp your load!!

P.S. We will not accept anything as a return that left without a tarp on it.
