Still purchasing lady beetles for your garden?

By | gardening, landscape maintenance, Trees | No Comments

A few years ago I met a home owner at one of our sites and she told me about her annual lady beetle buy and release events. I smiled politely and privately thought she was insane and had way too much disposable income. She paid $16.95 retail plus tax for a bag of lady beetles. As we learn from the fact sheet below this biocontrol business is extremely lucrative.

Now, a few seasons later,  there is a new Fact Sheet from the University of Washington Extension that clarifies the issue and it happens to be co-authored by my favourite horticulture scientist Dr. Linda Chalker-Scott.

As it turns out many gardeners buy lady beetles for their gardens and landscapes. And the fact sheet concludes that “release to open gardens and landscapes is unlikely to be successful.” Now my burning question is answered.

Control

Adult and larval beetles control aphids and scale insects, mites, beetle larvae and immature bugs.

 

Aphid problem

The site mentioned above has lots of tulip trees (Liriodendron tulipifera) which are known to attract aphids. The aphids suck on the new leaves but otherwise don’t harm the trees. Incidentally, don’t miss tulip tree flowers. They are spectacular.

Since aphids can’t process sugars, they excrete them. That’s why honeydew drops on leaves, cars and sidewalks. Then lady beetle sales go up. The lady swore that her lady beetle releases are effective. OK.

But perhaps you don’t have to spend your after-tax dollars on lady beetles. What if you can attract them naturally? Grasses and wildflowers will attract them to your gardens. Lawns not so much.

As we learn from the fact sheet, lady beetles eat fungus, fruit and occasionally vegetation. Adults look for sugar sources such as nectar or honeydew. These energy-rich supplemental foods improve lady beetle reproduction and survival over winter.

Take it easy on insecticides because they kill the target pests and natural predators.

Good or bad idea?

There are some negative aspects to this whole biocontrol business. First, we are removing populations from their natural ecosystems which may not be a good idea.

Second, native beneficial insects may suffer when we introduce non-natives. And third, introducing lady beetles may transport parasites.

Conclusion

In conclusion, I must say that the lady gets a gold star for spending $16.95 plus tax on a bag of lady beetles; and for inspiring this blog post. As we know from the new fact sheet, these lady beetle releases are unlikely to be effective. And yet, she swears by them. Perhaps the tulip tree honeydew attracts the lady beetles naturally.

I say, try to attract lady beetles naturally and save your money. Perhaps you can donate some cash to the University of Washington Extension so they can produce more science-based fact sheets.

‘Common strata plants’ e-book for new landscapers released

By | Books, Education, gardening | No Comments

Common Strata Plants: A Guide for West Coast Landscapers

I finally realized one of my dream projects: to self-publish an e-book for new landscapers. Since the internet has revolutionized publishing this is a great time to put your stuff out into the world. Are you not convinced yet? Then read James Altucher’s blog on self-publishing.

Why?

Why publish an e-book with common strata plants? Because it’s part of my job to train new landscapers in the field. And plant identification skills are one big part of that training. After answering the same plant questions over and over, I had an idea. I realized that we could tweak it by putting the most common plant species we see on our strata complexes into one picture file. And then publishing it in electronic e-book format and making it available for download online.

Two key ideas

  1. Repetition: Plants on our strata complexes tend to repeat and that works in our favour. Once the new worker learns to recognize shrubs like Viburnum davidii he will see them on other sites.
  2. The list: The plant list I put together comes from strata sites and represents, what I believe, is a good starting point. So just take the list and learn it. There’s no need to consult thick reference manuals or spend time making your own list.

Testing!

This was an important first run test because I have other projects in mind. So stay tuned by checking this blog. To read how I self-published the e-book, click here. Of course, the trick is to get new landscapers to download and flip through the e-book. I think employer incentives might help.

New workers are usually busy enough with machines and bedwork.  Plant knowledge comes later with experience. But let’s consider why plant ID is important.

a) Bedwork or finesse work can be completed faster when you can easily distinguish between plants and unwanted weeds. I’ve seen many new landscapers paralyzed in gardens because they weren’t sure what was what. If you’re not sure, don’t pull it. Don’t panic, just get better.

b) Landscape design requires exceptional plant knowledge. One day the new landscape worker might move up and pursue design work.

c) Nurseries only use botanical names so if you know your plants you can easily place orders and check them for accuracy. Always keep plant tags and study them.

d) Gardening, like design, depends on exceptional plant ID skills. I found this out when I apprenticed under my city gardener boss. Her plant ID knowledge was unbelievable. Eventually I found out where city gardeners make their money: in annual bed displays. The kicker is that when they meet they order new plants for next year by grouping their plant orders. You need knowledge and experience for this task. I respect all city gardeners for this.

e) Clients will stop you to ask questions and if you’re ready, you will impress them with your knowledge. As Red Seal journeyman on site I inevitable get called over by workers who are happy to deflect client questions to me. Great! I always take the heat.

f) One day your boss or client will take you for a site walk and ask for ideas. There won’t be time for Google searches. You have to suggest plants right there, on the spot. That can be stressful but not if you know some plants.

Conclusion

The plant picture book can be used by new landscapers as a starting point; and also by strata managers and strata unit owners who may wonder what’s growing on their sites. Knowing plant names makes communication with landscapers easier.

“Caring for plants” Korean short story

By | gardening, Magazines, Reviews | No Comments

As I was browsing through the magazine section of my local public library I noticed a short story in the New Yorker magazine (July 10 & 17, 2017). Caring for plants, by Hye-young Pyun, translated from Korean. Sure, why not.

It all starts with our protagonist in hospital, badly crippled. There was a car accident and, sadly, we learn that the wife didn’t make it. This is where gardening comes in. The wife loved her garden. She cared for her flowers and shrubs but now the garden looked rough and abandoned.

I have some experience with abandoned gardens. One of my earlier blogs deals with a true story from Japan. The wife commits suicide and her husband lasts barely a year or two. Their little front garden is still there but it no longer gives anyone pleasure. It is sad to see the weeds and over-grown plants.

Our protagonist eventually gets well enough to go home but he’s still in rough shape. His first caregiver is a riot and by far the best character in the story. Then she gets fired. And the mother-in-law enters the picture. We know she is sad and mad. She never liked the cripple.

When she isn’t helping her son-in-law, she is out in the garden. She knows that this was her daughter’s favourite spot so she does what she can to keep it up. Then she starts digging holes in the far corner of the garden.

Our protagonist is slowly recovering and still has to crawl to make it to the washroom. Then he mentions to his physiotherapist that she has been feeding him extra pills. Wasn’t that unusual? Perhaps. The physiotherapist, too, gets axed.

Now the mother-in-law starts talking about money and budgets. The son finds it odd and then discovers that his resignation at work had been submitted without his prior knowledge.

Then one day, he crawls to the window and sees his mother-in-law planting new plants in the holes she had dug. But wait. Is that an extra large hole in the far corner of the garden? Here we get to exercise our imagination. Perhaps tomorrow there will be a large tree delivered? Or is it meant for our crippled son-in-law. It’s up to you to decide how he ends up there. An overdose looks imminent. I think.

If you have some extra time at night or on the weekend, read this short story and let me know how you think the story ends.

 

Lace bug infested rhododendrons

By | gardening, landscape maintenance | No Comments

As frequently happens, I get interrupted from my tasks to attend to strata owners’ requests. Today was a statutory holiday in British Columbia so we hit the site with a California-style mow-blow-go service. Of course, this also meant that residents who would normally be at work were home.

And off we went to see the lady’s front entrance rhododendron. The owner said it’s been suffering with white flies for five seasons. She gives it fertilizer and prunes it twice a year to keep the height in check. It doesn’t flower much. Aha, I could feel a blog post brewing in my head.

Bugs on leaf undersides

I examined the leaf undersides but found lace bugs instead of white flies. Since both bugs are sucking insects I knew sprays are usually employed to control them. So I snapped a few photos and made a note to do some research when I got home. I’m also fortunate to have great contacts to reach out to when I need help. One is municipal gardener Tracey Mallinson and another is Dr. Linda A. Gilkeson.

The lace bugs are clearly visible.

Rhodo

 

IMG_5673ed

 

Let’s examine the rhododendron. It appears to be in too-sunny a location. Rhododendrons in shadier spots don’t suffer as many infestations. This goes for Azaleas and Pieris japonicas.

The shrubs looks OK from distance but the insect damage is obvious up close. Flipping the leaves upside down, it was easy to spot the lace bugs. The Pieris japonica on the left is also affected.

I have no idea how much rhododendron fertilizer the plant gets but I’m assuming the owner follows the label. Another suggestion online was to keep the roots moist.

The owner prunes the rhodo twice a year to keep its height in check. She enjoys the privacy she gets but doesn’t want to be overwhelmed. This made me think of Japanese gardeners who refuse to prune trees and shrubs that show signs of weakness. Instead they ask the owner to nurse the plant back to health.

 

Solutions

Best course of action in July would be direct forceful blasts of water on the underside of leaves. I’m sure there are commercial insecticidal sprays but once you go the chemical route you’re stuck. Dr. Gilkeson states that the sprays must be repeated 10-14 days later and there is some danger that the sprays could burn the leaves. We don’t have that problem with water; water is also considerably cheaper.

The best solution would be for natural predators to arrive and feast on the lace bugs. Patience!

 

 

Kuno garden

By | gardening | No Comments

When I arrived at Garry Point Park in Richmond last year, I was there for a 10km MEC race. I had no idea Garry Point Park was a large 75 acre waterfront park. Since I got there early, I went for a walk to check out the park and to take a few pictures.

Kuno garden

Imagine my surprise when, during my pressing search for a public washroom, I discovered a Japanese garden! No way. Ignoring my bladder, I shot a number of pictures. Kuno garden is tucked nicely into a corner. It commemorates the centennial year of the arrival of the first Japanese immigrant to Canada. Many people don’t realize that pre-WWII Japan was fairly poor. Fishermen emigrating to Canada had it easy compared to the “karayukisan” girls. They were the spare mouths to feed in small towns so they were sent to points in Asia to earn money with their bodies.

 

IMG_9831IMG_9053

The garden isn’t huge. It sports many pine trees pruned Japanese style; and the usual elements like bridges and lanterns. The plant material is local. Nothing exotic. I thought the garden was in decent shape.

Garry oak

Surprise discovery number two. To reach the public washroom I had to pass under Garry oaks from which the park obviously derives its name. Quercus garryana has round spreading crowns and thick, grooved, scaly greyish-black bark. It grows up to 20m tall.

Acorns are small with shallow scaly cups. Leave are deeply lobed and bright green above; paler with red to yellow hairs underneath.

As for my race, it went OK. I will always remember it for the farmer who closed the trail in front of us so she could shepherd her shaggy cows across. This pregnant pause confused my Suunto heart rate monitor. The cows were in no rush.

If you drive to historic Steveston, it might be worth your while to drive a bit more and check out this park. It was a pleasant discovery for me. Who knows, it might be the same for you.

Abandoned Japanese garden

By | gardening | One Comment

What happens to private gardens when the owners pass on and they get abandoned? I was thinking about this on my vacation this past August. The Japanese wisteria (Wisteria floribunda) at the house next door to my in-laws in Niigata City, Japan, was sticking out into the lane. So I took my mother-in-law’s ancient pruning tool and removed all shoots poking out into the lane.

I still remember the couple who lived in the house. They would sit in their kotatsu and look out into the lane through their garden. I lived next door for five years in the 1990s. Eventually the shock wore off as they got used to seeing a white gaijin. I recall only brief small-talk exchanges. I never learned their names.

Then one day, six years ago, I got a phone call from my wife who happened to be visiting at home with our little kids. The man from next door knocked on the sliding door with some urgency. Would my wife help him cut down his wife? Huh? She was still hanging on the side of the house, having committed suicide. To this day, I’m not sure why. Illness leading to money issues? Old age? Panicked and home alone with little kids, my wife sent him to the family construction office. Two office ladies helped him with his unpleasant task. My wife eventually calmed down.

Sadly, the man next door survived his wife by barely a year or two. And as he declined, so did the garden. The family now visits the house periodically but the garden stays untouched.

The Wisteria floribunda is growing through the Acer palmatum. The driveway is weedy. Inside the gate, there is Lavender that requires pruning; the weeds are very tall. Give me one hour or two and it will be good as new. But I wouldn’t even dare step inside the gate. The lady ended her life just around the corner. I think the space between the wall and house was used for drying clothes. The vibe isn’t good. May they both rest in peace.

Allright ladder fun

By | gardening, Landscaping Equipment, Strata Maintenance, Tips | No Comments

Tripod ladders rule

Japanese-style tripod ladders are excellent landscape and garden tools! Out in the field helping one of our strata maintenance crews with pruning, I took my lunch and opened up the Vancouver Sun. There, on page B3 was an article on ladders by Steve Whysall. Happy coincidence!

Let’s get to the best part right away. The single peg on the ladder is brilliant because you can position it almost anywhere. It will fit through hedges and you can punch it into your soil for stability. The most common size is ten feet. Since I was pruning small hedges in tight entrances, the small six foot ladder was perfect. It’s light to carry and maneuver and it got me just high enough to perform my cedar shearing. Lifting the extendable shears above my shoulders is tiring and leads to needless exhaust sucking. Why do that? Always position yourself for maximum output and comfort.

 

IMG_9389

6 ft ladder is easy to maneuver in tight entrances and gets you just high enough to shear the cedars nicely

 

Safety

Obviously, the bigger the ladder and the higher you are, the bigger the dangers. Always think about safety. Don’t rush. My only serious injury in seventeen seasons of landscaping happened while I was descending one of the bigger ladders. It was a 12 or 14 foot “widow-maker”. I started descending before my power shears were completely stopped. Yeah, I know, this was early in my career. Then my thumb met the steel blades. If it hadn’t been for my nail, the top of my thumb would have been missing. I still recall my helper down below, horrified by my blood dripping on her.

Incidentally, this was also the first- and I hope only- time when I jumped the line at a walk-in medical clinic. I remember an older gentleman probably waiting for his cough syrup, objecting to my line jump. I couldn’t care less.

The Allright Ladder Company is based in Vancouver and it is the oldest ladder company in Canada. They’ve been making them since 1921. Visit their website for safety information or read the Vancouver Sun article sidebar.

As the fall and winter pruning seasons come, I will use these Japanese-style tripod pruning ladders often. Consider getting one for your garden. Most landscape companies have them on their trucks.

Crazy about gardening: Des Kennedy

By | Books, Company News, gardening, Reviews | No Comments

Crazy about gardening

Sometimes you get lucky. Sometimes. Walking back to my car after returning bottles for deposit, I noticed a used bookshop sign. Closing, Final day, 70% off all used books. Aha. A very pleasant detour on my way to discovering Des Kennedy.

Half an hour later I walked out with the BC garden writer’s book. At $1.30 it was a steal. Kennedy is an award-winning writer and it shows. “Crazy about gardening” is a funny book. It’s subtitled “Reflections on the sweet seductions of a garden“. So we know this isn’t a technical manual. The lessons are subtle, mixed in with jokes and stories. If you let him, Kennedy has plenty to teach you.

There were also many spots where I almost reached for my dictionary. I also enjoyed the odd poem:

Life’s a short summer, man a flower.

He dies-alas! how soon he dies.

Obviously, just like stand-up comedy, your enjoyment is directly related to your age and experience. If you are an experienced gardener, you will definitely be entertained. If you are new to gardening, read and learn. Your vocabulary will also improve.

Some highlights

Kennedy hires a water diviner to find water on his property. A water witch. I find this fascinating because my own grandfather did this with outrageous accuracy just outside Prague. As a little city kid, visiting the country, I found it amazing. Grandpa would pick a branch, slice one end in half, grab one end with each hand and walk. Once he hit water, the top uncut end of the branch would dip down towards the ground. Success. Grandpa also made money by digging wells. The hard way.

Dog days droop. Kennedy makes fun of the late summer period when what was beautiful is all of a sudden dreary and desiccated. Pests multiply. April energy is long gone. The gardener temporarily loses grip.

Lawns. We know they use water, fertilizers, herbicides, and require time and effort to maintain. It’s a bizarre fetish. Once the lawn is nicely cut Kennedy admits to feeling a “bizarre little thrill of satisfaction, of emotional well-being.” I concur. There is something to this.

At $1.30 this book was a steal. Des Kennedy is worth whatever Amazon charges for his books. Give him a try.

Believe in Bergenia cordifolia

By | gardening, Landscaping, Plant Species Information | No Comments

First contact

My first encounter with Bergenia cordifolia was several years ago with my manager. She bent down and furiously started rubbing the leaves to demonstrate how the plant got its common name ‘pigsqueak’. And so we all rubbed the leaves to learn our lesson. Some no doubt turned their thoughts to bacon.

2016

Fast forward to 2016. Out on a site walk with my boss and the garden liaison, I was shocked when the lady asked us about removing a huge clump of Bergenia. What? Really? One person decides on a large landscape edit? They obviously had not flowered yet and they were in a perfect location close to a sidewalk. Bergenia form nice clumps but don’t spread quickly. Luckily the lady got side-tracked with other projects.

Then, at home one day in summer, seeking happiness by de-cluttering, I ran into a clipping from March 2008. It was a Garden West magazine article by Carol Hall. In it she correctly defends Bergenias. Finally, one person that made sense. Let the pigs squeak. Forever.

Plant details

Siberia and Himalayas native, this early-blooming perennial is tough as nails. Once it is established, it requires very little maintenance. I remove any brown leaves before liaisons get upset; and I remove spent flower stalks. That’s it.

Hall thinks that Bergenia’s lack of popularity stems from being stuck in 4 inch nursery containers. To fully appreciate the plant you have to see it established in your garden. I believe she is right. See my pictures below.

Other than situated by sidewalks, Bergenias are also good for front border definition and as year-round accents in mixed landscaping. You can also mass them under deciduous trees.

Landscape maintenance mistakes, vol.3

By | Edging, gardening, Landscaping, Lawn Care | No Comments

Here is volume three examining basic mistakes made in landscape maintenance. Learning from other people’s mistakes is much easier. It speeds up our progress. And to become landscape professionals we must progress. That’s mandatory.

 

A) Re-fuelling like pigs

Sure, accidents can happen. But unnecessary fuel spills cost money, they pollute the environment and they look awful. Imagine if you park your truck in the same spot once a week. It becomes an eye-sore and a potential source of complaints.

Gas up on tarps. (Stay away from grass as it burns and turns yellow.)

 

IMG_6925edit

 

B) Don’t leave deep edging chunks behind

Proper deep edging requires a 90 degree edge. Nothing else will do. As you deep edge you will most likely generate some turf chunks. When you clean up, remove all chunks. Finesse the bed like a pro.

 

IMG_6351edd

Inadequate clean-up; note weeds and chunks

 

IMG_6354d

Much better!

 

C) Mower collisions with trees

This is horrific. One collision may be fine. The tree will be forced to spend precious resources on fixing the damage, instead of on growing. Repeated collisions will kill the tree as water flow is interrupted. Keep your mowers away from trees. Period. Put up tree guards.

 

IMG_6742

A tight fit. To stay on the curb, the mower deck collides with tree bark. Weekly!?

 

D) Stepping on frosty lawns

If you can help it, stay off frosty lawns. When the lawn is frosty, the grass blades have little oxygen and water inside. That means they can not bounce back the way they do in summer. They get crushed.

Stay off frosty lawns if possible

With little water and oxygen inside frosty grass blades they can’t bounce back and get crushed.

 

E) Mohawks

Mohawks result from improper overlap. When you finish mowing a line, pivot on the back wheel as you turn. Do not move the back wheel, just spin it around. That should get you nicely lined up.

Mohawks also result from failure to mow straight in laser lines. It takes some practice. The mohawks must be fixed because one week later they will be really noticeable. Practice mowing until you eliminate mohawks forever.

A huge Mohawk. Practice!

Have fun in the field.
