The last service before Christmas

By | landscape maintenance, Seasonal | No Comments

The last week of service before the Christmas break requires focus. Most people have holidays on their minds but it’s very important to leave your landscapes looking sharp. This is how you do it.

Simple

Keep it simple. This is a bad time for major projects and heavy pruning. This type of work should be written down in your notebook for January. So what do we do? We check all high-profile entrances and walkways; and inside roadways.

Today I raked out the top boulevard of my site, including leafy debris behind the hedges. Since residents, neighbours and holiday visitors use and drive-by the boulevard, it should look sharp. And today it did.

I did a little bit of hand snipping on the tops of Pieris japonica shrubs. Very lightly, just to take out the spiky growth. Unless you live in the complex, you can’t tell the shrubs were topped.

Before: note the spikes on top.

After: it still looks natural after pruning.

 

Backpack blow

Once my raking was done, I blew the entire site. This is a perfect time for a good, detailed blow. I normally hurry to get this noisy task out of the way but not today. Today everything got blown: the inside roadways, patios and lawns. I also blew the forest buffer zone where leafiness tends to accumulate.

After pile pick-up I hit a few weedy patches and touched up some deep edges.

The hardest part of the day was cleaning up the garden liaison’s garden. She has a Japanese-style garden and does her own maintenance but I had to clean-up cedar clippings from a few weeks ago. Cedar pruning always generates secondary drop and here I had to hand pick the clippings from inside her Hellebores. Carefully.

Note that this sort of work shouldn’t be delegated to your helpers unless they’re experienced and follow directions well. The previous company pruned the liaison’s cedar hedges too hard; and they’re no longer under contract with this strata!

Final check

I walked the small site at the end of the day to double-check everything. I also noted work tasks for the new year. When I pulled out from the site I was satisfied that it was clean for Christmas.

Happy holidays!!

 

 

Another classic residential pruning job

By | Company News, landscape maintenance | No Comments

The title of this blog post says ‘classic’ because the home owner was on a budget and had clearly let her hedges go wild. And now she was desperate to reclaim some space and light from her Portuguese laurels (Prunus lusitanica).

This is common with homeowners. They start out with huge ambitions but a few years later they get overwhelmed and call in professionals. Then you don’t hear from them again for several seasons which is a mistake. Good, regular maintenance is best. I could tell from the garden weeds that not much happens around the patio other than smoking.

The list

Luckily, the lady was still home when I arrived so we could talk about the work and her expectations. This is extremely important so you avoid any nasty misunderstandings.

The list was easy for an experienced landscaper:

  1. Prune large fence line hedge (Prunus lusitanica) but only “tickle” the tops so neighbours aren’t visible from the patio
  2. Prune the globe hard, especially off the gutters
  3. Clean up the Japanese maple (Acer palmatum) by the window
  4. Remove one dead cedar (Thuja occidentalis) by the patio stairs
  5. Blow the leaves off the front lawn and from under the large hedge

 

Pruning

The pruning is easy when you have sharp shears; and the laurel is fairly soft, too. The only glitch was the slick wooden patio in the back. There was no way to anchor the ladder peg. Luckily I found a cement block under the hedge.

 

IMG_3357

Safety first!

 

Clean-ups

If you read my blogs regularly -and you should!- you will know that I harp on doing great clean-ups that match the pruning effort. Poor clean ups detract from your pruning work. Always clean up well.

Final courtesy blow is a given. I left the residence feeling happy with my effort. I just wonder how many seasons they will let it go before calling me back. Regular maintenance is best! I can’t stress that enough.

Ornamental grass cutback: time it right

By | landscape maintenance, Seasonal, Species | No Comments

I was on a large strata site last week planting winter pansies and testing out a new Stihl brush cutter. Finished for the day, I descended down the long private road that winds through the complex. And what really struck me was the beauty of the ornamental grasses. They were gently moving in the late afternoon sun and they put on a great show. They were ornamental for sure.

 

IMG_3881

 

IMG_3856

 

IMG_3884

 

 

Pressure

Unfortunately, the beautiful Calamagrostis x acutiflora ‘Karl Foerster’ were coming down. So you have to ask yourself why this is happening just as the grasses start to look their best. It comes down to pressure because this particular strata site is huge. It takes four weeks to make one full maintenance rotation. And the fear is that before the grass area is due for service, rain and wind will have destroyed them. That’s too bad because the show they put on along with their cousin grass species totally warmed me up. Now all that was left was a grassy stump to look at until next spring. This totally defeats the point of planting these grasses when they’re not allowed to be ornamental.

Note that there is always the possibility of rot in the centre when the grass is cut back too early.

 

IMG_3858

This is it until next spring. Rot in the middle is always a danger.

 

 

Cut back timing

Ornamental grasses flower in the fall and when everything else in the landscape fades, they give us something to look at. Personally, I cut them back only when they’re all broken up on the ground.

If you can let your ornamental grasses stand into winter, you might get rewarded with a beautiful frosty look. And birds also feed on the flower spikes in winter when there isn’t much else to eat.

If you can, let your grasses be ornamental and enjoy them well into spring. If you must cut them back, do it when they’re flopped over and hugging the ground.

Blow like a pro

By | landscape maintenance | No Comments

It’s October, 2018, and leaf season is here. Landscape contractors rely on their backpack blowers to clean-up leaf avalanches on their sites. If you drive around you’re bound to see a few a rose-cheeked landscapers blowing for hours.

I personally don’t stress about leaves. I love fall and I clean up the leaves as well as I can. Then I return the following week for more.

Aside from leaf clean-up blowing, there are two more blowing techniques every landscaper must know.

 

IMG_3375

 

Pre-blow

Early in leaf season when the leaf drop isn’t overwhelming, a pre-blow can be a great time saver. Pre-blow involves a quick blow of your site where leaves are blown onto lawns and then mowed. This eliminates time consuming leaf pile pick-up with rakes.

Simply mow over the leaves and bag everything. Then all that’s left to do is a final touch up blow. The only issue is judging the right amount of leaves. If the leaves really accumulate after your pre-blow, the mower will struggle to shred them when you mow. Don’t kill your mower. That’s why this technique is best used early in the leaf season. I think it could be used more in landscape maintenance.

 

IMG_3462

This is a well executed pre-blow. There isn’t enough leafiness to overwhelm the mower engine or to start raking piles.

 

 

Final blow

As the name suggests, this is the final courtesy clean-up blow. But I’m finding that many new employees only concentrate on the actual clean-up. With proper training they would know that their final blow also doubles as the final check.

Yes, foremen are responsible for checking their sites in theory but it’s not always easy in practice. That’s because some strata sites are huge and asking the foremen to walk the entire site at the end of the day can be too much.

So the worker doing the final blow is responsible for checking everything over as she goes. That includes missed debris piles, full green waste tarps, empty tarps, open gates and missed hand tools. It’s up to the worker to alert the foreman so we avoid calls to the office later.

Lawn care mistakes must also be corrected. Mistakes happen. Nobody goes home until missed lawns are mowed and huge mohawks eliminated.

Again, I find that new workers aren’t trained to perform final site checks when they blow. Once they get into the habit everything runs smoothly.

When a missing hand tool is discovered on site later, it means that the area wasn’t blown or the worker only occupied himself with blowing, not checking.

 

IMG_2358

This missed tarp was discovered during the final blow.

 

 

IMG_2366

This yard didn’t get mowed at all.

 

Conclusion

Consider training your landscape workers to perform pre-blows and final blows with site checking. Your whole operation will be smoother.

Water your new installs for success

By | landscape maintenance | No Comments

It drives me crazy when I see my landscape installs neglected and suffering from lack of water. It must be the biophilia effect because I feel responsible for the suffering plants. An yet, I can’t do much about it because it’s up to the owners to water their plants. I water them in on install day.

Water for success

This is your main take-away from this blog post: new plants require copious amounts of water to properly establish. As water goes in, roots chase it down and extend. And on it goes but not without water.

 

IMG_1736

Disappointing.

 

This is the worst case because I did everything myself. I removed the dead cedars, dug the holes, bought and delivered the new cedars (Thuja occidentalis ‘Smaragd‘), planted them and watered them in. Months later I took this picture with some disgust. Directly behind me was a perfectly functioning garden hose. It just takes time to properly soak the cedars once in a while. Cedars are very thirsty in their first year.

 

Magnolia

 

IMG_1734

 

Because of our summer drought this Magnolia tree exhibited early leaf senescence. With some watering from me it bounced back by pushing out new foliage. The cedars behind the tree weren’t so lucky. To be fair, shading from the Magnolia becomes permanent over time but I suspect lack of water was also a major contributor to this carnage.

Note the garden hose in the picture. I have no idea why it can’t be turned on and left to soak the area for twenty minutes. Again, it’s up to the owners to water.

 

Success!

Luckily, some owners get it. This unit has two little kids and the owners water. Plus they installed a soaker hose so their new cedar hedge would establish. This space used to be bare with only two stumps to look at and I, literally, paid for this install with my blood. Because the nearby creek breeds a lot of summer mosquitos this project was an adventure. My next blog post will be on my intimate knowledge of insect repellents.

 

IMG_2777

These owners get a gold start for watering.

 

As we ease into fall, there will be more landscape installs. It’s absolutely critical that owners water their new plants. Good plant establishment can only happen with good watering.

How professionals handle low-profile corners

By | landscape maintenance | No Comments

I don’t believe in discrimination. Every part of the landscape should receive attention. Unfortunately, landscape companies are busy and often low-profile areas get less attention or worse, they get ignored. But that’s not my style.

 

Commercial site corner

 

IMG_8163

Before.

 

This ugly corner was on my list for weeks and I finally got to it. The most obvious blemish is the dead dogwood in the middle. The last thing you want on your site is dead plants. So I did the most economical thing available; I flush cut it as low as I could.

The entire bed was overrun with prickly bramble (Rubus armeniacus) which just spreads so I cut it at ground level knowing that this will be a fight until I actually dig it up.

Next came light hand pruning of the Pieris japonica shrub followed by raking and weeding.

 

IMG_8170

After.

 

It’s not exactly a beautiful garden spot that would inspire young lovers but the whole corner looks much better and I could take it off my mind.

 

Strata site corner

 

IMG_8783

 

This is the finished product. A crew came through and they pruned the Euonymus alatus shrub on the left. Great. If you like average, that is. So what would a landscape professional do? What would you do?

One, there is still debris on top of the shrub and, unless it’s removed, it will turn brown and make the whole shrub look unsightly. Always check plant tops when pruning.

Two, there is a dead shrub in the corner and no wonder. It’s planted under a double under hang so it doesn’t get much water. So why keep it? Remove it.

Three, the shrub on the right has lots of dead in it so I pruned out most of it. I probably should have power sheared it.

Four, there are obvious weeds like snapweed (Cardamine oligosperma) which snap when they are mature and shoot out seeds everywhere. It’s a bad idea to let weeds produce seeds. The corner should have been weeded right away after pruning.

 

IMG_8787

After.

 

The photo above shows the finished product. There are two spikes still visible on top of the right shrub but overall it is much cleaner. Unfortunately, it took two service visits to get it to this condition. As the workers gain experience they too will be able to read the landscape better and give all corners the attention they deserve.

Summer dangers in the landscape

By | health and safety, landscape maintenance | No Comments

There I was raking out a bed and to get under a rhododendron I had to bend down and use my hands. Seconds later my left thumb was in excruciating pain. Then I quickly clued in: my hand had just passed over a ground nest full of wasps. So I hosed off  my thumb for several minutes, finished the day and left for home in a foul mood. My left hand was swelling up with every passing hour.

There are many dangers facing landscapers in the field and in summer, insects are danger number one. Still, this was my only sting all season. And as long as I can do my job, I ignore all wasps. It’s usually the residents that panic.

One week later I ran into a tree nest full of wasps which is much easier to detect when the wasps are flying in and out. And I was ready, too! I had my spray can ready so I gave it a nice shake and aimed it at the opening. Out came a lot of white foam.

 

IMG_1647

This is much easier to spot than….

 

IMG_2425

…a ground nest.

 

Here is the key point of this blog post: when you buy a spray can for wasps and hornets, buy the gluey stream type not foam.

The foam coated the opening and the entire part of the nest facing me. Some wasps even escaped from the opening. Two weeks later I found live wasps still inside the nest. This doesn’t happen with the glue type spray can. The toxic glue comes out in a steady stream and plugs up the nest opening. Case closed.

Hint: use goggles and pray that the wind is blowing away from you.

I waited for two weeks before removing the nest. When I examined it, I found two wasps still alive inside. Hours later the pest control technician found some nest leftovers and questioned me about it. Most likely I had just prevented him from generating a fat invoice. Safety first!

Late summer wasp problems are common in landscaping so be careful. And if you buy a spray can to control the insects, do NOT buy the foam version.

 

IMG_2424

Buy this type of spray, NOT foam.

 

Nothing to do on site: how to bust this myth

By | landscape maintenance, weeds | No Comments

This is my favourite myth of all: there is a landscape site or garden with nothing to do on it; it’s that perfect. As an expert in strata (multi-family complex) landscape sites, I find this extremely laughable because landscapes grow and evolve. Depending on the season you’re in, there is always maintenance work to be done.

Two types

I find two types of foremen who confidently assert that there is nothing to do on their sites. One is the outright lazy, disengaged person and the other is too new to know better. Usually, it’s the newly promoted landscape crew leader or foreman who fails to read his landscape.

And this happens more than you think.

Details

Say, it’s July and the site doesn’t want you to mow weekly. Perfect! That means you can take care of details you wouldn’t normally have time for. I love these situations; I embrace them because there is ALWAYS work on site.

Just think details and you’ll start seeing lots of work om site. Below are some examples of what to look for. You will find others in your garden or on your strata site. Learn to read your landscape as you develop what’s called a landscape eye. It takes time so obviously new foremen struggle at first. I often take them on site walks to point out little details and I do it gently. It’s a learning experience. So try it in your garden or on your strata site.

 

Weeds

There are always weeds on site, especially in lower profile corners. The groundcover in the bed below is full of weeds.

 

IMG_9808

Weeds, there are always weeds.

 

IMG_9790

Oh my, invasive Knotweed covered by invasive morning glory.

 

IMG_9804

This shrub is screaming for a small circle well.

 

IMG_9806

This makes it obvious for lawn care people.

 

Knotweed

This border patch of Japanese knotweed (Fallopia japonica) is an obvious candidate for removal. As in top removal because the actual weed is difficult to remove permanently. It’s so bad, some green waste facilities don’t even accept it.

 

IMG_9791

Super invasive Japanese knotweed (Fallopia japonica)

 

IMG_9800

Knotweed detail.

 

Missed pruning debris on top of plants is a common problem so hand-pick the dead brown parts now that they are easy to spot.

 

IMG_9788

Dead debris on a yew (Taxus).

 

Watering is for your clients to do but if you have extra time and you see a complete yew hedge struggling then you can spend some time on it. This hedge is clearly struggling so I reconnected the drip line and hand-watered everything. The drip-line should be left on for hours.

 

IMG_9748

There is no such thing as perfect landscape without any work in it; it’s a myth. Look for details and you will find them. Acquiring good “landscape eye” skills takes time.

How aphids get tulip trees in trouble

By | gardening, landscape maintenance, Trees | No Comments

I don’t normally buy the Vancouver Sun because they discontinued their garden column but a story last Friday caught my eye. The title read “Aphid secretions shower property with sticky goo.” Friday, August 3, 2018 Vancouver Sun.

The problem

I have some experience with this issue so I had fun reading about this East Vancouver case. Every summer aphids descend on tulip trees (Liriodendron tulipifera) and feed on their leaves. But since aphids can’t process sugars, they secrete them and the sticky honeydew lands on cars, driveways, etc. The affected couple in the story complained about having to wash their car and their difficulty of moving their baby carriage. The sticky honeydew also attracts wasps which freaks out most new parents.

 

IMG_4239edit

Tulip tree leaf underside covered in aphids.

 

 

The City of Vancouver allegedly once brought them ladybugs, the aphids’ natural predators. This is what amazed me in 2017 and inspired me to pen a blog post about it: people paying after-tax dollars for ladybugs in the store and releasing them on their trees. One major issue is telling the ladybugs to stay on your tree. Because they move around it’s not an effective tactic.

Solution?

In the past, the couple in the story purchased their own ladybugs “but it made little difference”. So now they want the city to spray or remove the tree. I believe that would be very harsh treatment for this beautiful tree because aside from the many ecosystem services it provides, it also has beautiful flowers.

Luckily, the City of Vancouver knows that removal would cost $1000.00 per tree plus extra costs for replanting. There isn’t enough budget for projects like this which is good news for the tree.

 

Conclusion

While I understand the hassle of sticky honeydew, let’s remember the many ecosystem services trees provide for free. I especially love the tulip tree flowers which come out as the trees leaf out. Complete removal because of aphids would be horrible. Perhaps a picture of one tulip tree flower will distract you from aphids and city help lines.

Lessons from strata owner meltdown

By | Education, landscape maintenance, Seasonal | No Comments

On large strata (multi-family) complexes you can expect to get some negative feedback during the season. Normally it’s addressed as soon as possible and if you’re lucky, the strata unit gets educated. But how do you handle a full-blown meltdown?

Keep it cool

Definitely keep it cool. For me it’s easier now that I am a supervisor of a certain age but it’s never pleasant. So, first, take a look at the picture below. What do you notice?

 

IMG_1203

 

Obviously, the lawn is dormant because it’s early August on the West Coast and the lawns aren’t irrigated. You will also notice pockets of new soil and seed.

Now, the owner of the unit (remember he owns his house, the lawn belongs to the complex) came out storming about the bad condition of his lawn. So I told him it needed water and that set him off. He told me there was no need to be rude; he was 55 and well-aware that lawns required water! Really?

Here I took a deep breath and insisted that there wasn’t anything rude about my comments. For the lawn to look green during an early August heat-wave and for the seed to germinate he had to water his lawn thoroughly several times a week.

Incidentally, if you’re new to the West Coast, dormant lawns will green up with fall rains.

Still red in the face, the man showed me his broken hose nozzle and insisted one of our workers stepped on it. So I sucked it up and bought a new nozzle for $20, tax-included.

There were some other complaints that don’t need to be listed here. They should have been sent to the strata.

 

Lessons

Obviously, getting through the whole year without any complaints would be ideal but some sites are huge and they’re populated by all sorts of people. So what lessons can we draw from this blog post?

a) There will be some negative feedback no matter how well your season goes. When strata councils change you can expect even more hassles as new members try to put their stamp on things. At this complex the strata council is new.

b) Strata owners should go through their strata councils and management companies. Assaulting landscape workers on site is not the proper way to handle it.

c) Non-irrigated West Coast lawns will most likely go dormant during the hottest parts of summer. Don’t panic because they will recover with fall rains.

d) Keep calm and stay polite because you represent your company. But don’t be afraid to educate your clients. Clearly, the owner knows about lawn watering but he isn’t doing it. His new soil and seed were dry. I watched him water later and it can best be described as a gentle sprinkle. I wasn’t about to show him how to water his lawn properly. He’s 55, he can figure it out. (The lawn requires a nice deep soaking a few times a week; always follow any municipal watering restrictions.)

e) Let it go. I’ve had to learn to let go of things as a supervisor. I answered all questions where I could, I bought a new nozzle, took pictures and notes, and notified my vacationing boss. Writing this blog post is therapy.
