Rhododendron pruning 101: rejuvenation

By | Education, gardening, Landscaping, Tips | 2 Comments

Three pruning actions on rhododendrons

There are three pruning actions associated with rhododendrons. One is the removal of spent flowers (trusses) and any diseased or dead wood. Most rhodos produce seeds and you can get your rhodo to concentrate on growth by removing the spent flowers. Do this soon after flowering before the new buds get big and set. I prefer hand pinching. Just be careful so you don’t injure the buds below. Use hand snips if you are worried.

Trusses still on

Trusses pinched off

 

The second pruning action is for shape. Just follow the branch down to the last whorl of leaves you want to keep and cut just above those leaves. This is what I recommend to clients who wish to keep their rhododendrons from getting too big.

But what if your rhodo is too big? Now what? In this case we employ pruning action three: rejuvenation, which sounds better than renovation. This involves bravely making large cuts and significantly reducing the plant size. This works because rhodos are special. Examine their bark and look for tiny pink dots. Those are latent buds. Always aim to cut above these buds. Best case: cut above a cluster of latent buds. Then watch.

One example

Here is one example from my work site. This rejuvenation pruning was done at a corner unit where there was a problem with vehicle sight lines. Drivers couldn’t see properly when turning. So out came the saw as soon as the request was made. This was the result.

Not much to look at right after pruning. Reduced to 30%.

Rhododendrons are forgiving plants. Pinch off flower clusters (trusses) soon after flowering and prune for size. Bravely make big cuts if rejuvenation is required.

Notes on urban agriculture

By | gardening | No Comments

Strata garden plot

 

There she was. A lovely mother of two busily tending to her community garden plots. It was a sunny morning and the plants were in need of water. The two plots are small but her strata council has approved the construction of one more plot. It wasn’t easy, nor quick, but there will be more space for growing stuff. Not every strata council is this accommodating. Most condo patios are either too small or don’t receive enough sunlight for serious growing.

There is a water barrel for watering. All members take turns watering and taking care of the plots. The harvest is shared among them. Community.

Globe article

Soon after meeting this lady, I opened up my Globe and Mail newspaper. I was immediately grabbed by Ian Clarke’s article “The future is inefficient, and it tastes just fine” (The Globe and Mail, Wednesday August 10, 2016)

It is clear that there is more and more interest in these gardens. A mother of two is happy to know that her vegetables are organic, she can save a bit of cash and use the plot to teach her kids about food. This is nothing new. Michelle Obama famously planted  a kitchen garden at the White House to promote the value of urban agriculture.

Several years ago I had a community garden plot in the Burquitlam area of Coquitlam. Busy at the time and annoyed with one of the garden directors, I gave up. Now I wish I hadn’t.

As The Globe article mentions, during the world wars, the government encouraged  people to plant food gardens in all available urban spaces.

 

Urban agriculture

From tiny backyard plots, community and school gardens to larger commercial farms, the urban agriculture sector is expanding. It will never replace rural farms. But check out the benefits. It can:

  1. reduce the carbon footprint of our food
  2. create resilient cities and food systems
  3. reduce the urban heat island and air-conditioning costs
  4. reduce demands on city infrastructure
  5. create jobs

Urban agriculture is:

  1. smaller in scale
  2. usually more biodiverse
  3. responds to local tastes and demands
  4. technically inefficient as it uses local workers who make more cash
  5. it is very efficient at producing good food and jobs

 

I can’t wait to see how the third garden plot develops.

 

 

 

 

 

Develop your landscape eye

By | gardening, Landscaping, Tips | No Comments

Landscape eye

Developing your landscape eye is a critical skill. It takes time to develop but your landscape, bosses and clients will thank you for it. Basically, landscape eye refers to your ability to read a landscape and figure out what’s missing, totally wrong or just slightly off. This usually comes with experience once workers are fully proficient on all equipment.

I started landscaping at a prominent Lower Mainland landscape maintenance corporation we don’t need to name. There, the in-house seminar on “Developing your landscape eye” was delivered by the company owner. Not managers. The owner. That was no accident. Workers with good landscape eye can make corrections which leads to sharper and healthier landscapes. This seminar was a platform for the company owner to train his workers to see the landscape the way he does.

Some obvious examples are weeds, shrub spikes, walkway obstruction, flower deadheading, broken tree branches, tree branches touching buildings, missed blade edging, lawns that don’t look lush, dead plants, garbage, debris, cedar pruning lines, shoddy clean ups, etc.

Examples

As you move and work through your gardens and landscapes, pause to take a good look. Does it all makes sense? Is it all healthy and beautiful? Work on developing your landscape eye.

Garden Days.ca freestyle

By | Education, Events, gardening | No Comments

As reported in the CNLA Newsbrief  (spring 2016, vol.25 issue 2, page 4) Garden Days are Canada’s Annual Celebration of Gardens and Gardening. It all starts with National Garden Day, always the Friday before Father’s Day. June 17-19 this year. That’s easy to remember for fathers.

This is basically a three-day freestyle celebration of gardens. People can visit their favourite gardens, work in their own gardens or stop by a garden centre for some inspiration. Some businesses organize barbecues, fundraisers, festivals or special sales. Lovers can enjoy a walk through botanical gardens.

This is what I did with my kids.

  1. We watered and checked our patio plants, a mix of annuals, perennials and plants that are being “parked” for the time being. The most interesting pot is a mix of wildflowers I received as a gift from my kids. I simply dumped the seeds out into a new pot and waited.
  2. When my son showed me his Minecraft house creation, I helped him improve the landscaping by adding more flowers. Virtual gardening. I said this was freestyle.
  3. On the way to soccer we walked by the Port Moody recreation centre and identified local trees, like cottonwoods which have a tendency to self-prune by dropping branches.
  4. Instead of my usual “fake” bedtime story, I told the kids about my audiobook “Lab girl” by Dr. Hope Jahren. In it she mentions resurrection plants; plants so brown and dead it’s hard to believe that with moisture they come back to life. They are the only plants that have figured out how to grow without being green!

Nematodes vs. European chafer beetles

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

One of my clients on the Westwood Plateau in Coquitlam loves his lawn. When his lawn got ripped up by animals searching for European chafer grubs, he was shocked. He installed an irrigation system and hired me so his lawn could receive good, consistent care.

Repaired lawn

 

Once I repaired the damaged lawn, my client decided to try a nematode application. He pre-ordered the nematodes in June. $80 cost plus my labour.

June is a busy month for the European chafer beetles. As they mature, they emerge out of the lawn and fly off to nearby trees to mate. Then they look for new lawns to lay their eggs in. If you’re lucky, they pick your neighbour’s lawn. Cutting your lawn higher means it’s more difficult for the beetles to stick their back ends in to lay their eggs.

 

IMG_5049edit

Europen chafer beetles ( the bottom 3 are playing dead!)

 

The recommended nematode application window is from the third week of July. This is what we did once the nematodes arrived. They were kept cool in a fridge.

A) Cut your lawn short and water it really well prior to nematode application. The microscopic nematodes require water to penetrate into soil. There they seek out the grubs. Important: get a municipal water permit.

B) Because the nematodes  are photo-sensitive we waited until there was no direct sunlight hitting both the front and back lawn areas.

C) We prepared a 4L bucket of water. The we opened the package and soaked the sponges in the water. Also soak the plastic bag holding the sponges.  Carefully squeeze each sponge ten times. Then stir the solution well. Discard bags and sponges.

D) Carefully fill up your hose end sprayer. We used a funnel. Don’t forget to stir the solution before every re-fill.

E) Turn on water and spray methodically. Use sticks, tools or tape if it makes it easier for you to keep track of where you’ve sprayed. We soaked the worst damaged spot.

F) Water your lawn after application.

If everything goes well, the chafer larvae will get eliminated by the nematodes. Two problems with nematodes is that they might have to be applied annually and they eliminate all grubs they find in the soil. In the meantime, the lawn will receive better care.

 

European chafer beetle battles: more lawn, really?

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

So your lawn has been damaged by animals looking for European chafer beetle grubs. Now what? Do nothing and look at the mess? Get more grass? Or give up and go for alternatives?

I have clients on the Westwood Plateau who last year witnessed black bears digging through their back yard lawn looking for chafer grubs. Their lawn was weak: areas covered by trampoline were mossy, there was no regular irrigation or fertilization. Chafer beetles laid eggs in it the previous June.

Heavy animal damage as they look for tasty grubs

 

I came to install mulch and prune their evergreens. Could I fix the damage? Yes, of course. Do regular lawn maintenance? With pleasure.

Client wants more grass

There are home owners who love, LOVE, their green grass. This particular home owner wanted more grass. He installed a new irrigation system, paid for my fix and ordered nematodes. The lawn will be cut bi-weekly and higher than in previous seasons.

Step 1: cut the lawn short and remove lawn chunks

 

IMG_5664edit

 

Step 2: power rake the lawn, rake up the debris and mow it again

Step 3: install good lawn and garden soil and rake it in

Step 4: overseed, gently rake in seeds, add starter fertilizer, roll it with a pin to level any bumps and to ensure soil-seed contact; and water

Step 5: check for germination after 7+ days and overseed any obvious open spots

Step 6: order nematodes in June and apply them to the lawn in late summer/fall

Step 7: cut higher, irrigate and fertilize as required

 

IMG_5644edit

Mid-July 2016 lawn fixed, regularly irrigated, nematode application pending

 

Clients who love their grass can repair their lawns, maintain them well, and apply beneficial nematodes in the third week of  July. There are no guarantees with nematodes but this home will be a good test site. More on nematodes in a future blog.

 

 

 

July colors rule!

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

Summer color

Summer colors rule! It’s a lot of fun working in July landscapes. These are the days I dream of on cold November days. Those dark wet days when I have miles of cedar hedges to prune and the only source of heat is the gear case on my shears.

Mass-planted Rudbeckias are very warm and hard to miss; lilies are everywhere; and Liatris spicata demand attention. My favorite silk tree, Alibizia julibrissen, smells so great I get close enough for its silky flowers to tickle my nose. I even snipped off a few flowers, sealed them in a bag and brought them home so my kids could enjoy the scent.

Below are plants I encountered while working in the landscape. The Hosta flower picture is my first ever. Until now I never photographed an individual Hosta flower.

Plant identification

Summer is the best time for plant identification work. As you move through your gardens and landscapes look around. Can you name some or all of the species? When you encounter your favorite plant, look it up. Most plants have their own stories and interesting details.

Can’t name some? Take a picture and research them. Better yet, buy some plants and plant them in your garden. That’s the best way to remember them.

Plant tag thief

When I install plants I always keep the tags. When I find discarded plant tags, I keep them. I also take pictures of tags in clients’ gardens. I try to stay away from garden centres because, inevitably, some tags of plants I didn’t know will end up in my pocket. That’s when teenage garden centre assistants roll their eyes and search for the manager. Lesson is over. I head for the exit.

What are your summer favourites?

Million dollar homes

By | gardening, Landscape Industry, Landscaping | No Comments

Multi-million dollar homes have been in the news for a long time. Foreign buyers come in, flush with cash and locals are priced out of the market. Or so one story goes. I am not an expert on real estate. Nor am I in a position to buy one of these Vancouver homes. But, I am qualified to work on them.

When my buddy recently asked me to help him upgrade his Vancouver home, I jumped at the chance. Not only was the compensation generous by BC landscape wage standards, it was also consistent with my personal mission. The mission being to constantly seek out new experiences, both in my personal life and work life.

The goal

The goal was to upgrade the landscaping very quickly so the house could be put on the market. All new flowers had to look good for the next three months or so.

Basic tasks

 

  1. weed the front garden
  2. prune rhododendrons
  3. remove patio crack weeds
  4. prune plants off upper stairwell
  5. expose house numbers obscured by Cotoneaster
  6. push back ivy from main entrance area
  7. remove dead shrubs
  8. prune Forsythia spikes
  9. install new soil
  10. install new plants
  11. line trim wild looking lawn
  12. cut out cherry suckers
  13. clean up blow

The main entrance beds were planted with three new roses, Dianthus ‘Kahori’, Hemerocallis ‘Scottish fantasy’, petunias and cacti. I helped with the install; not the design and plant selection. The only tricky part was planting the Yarrow because the tall stems can break off.

After two work sessions the house looked much better. I can’t wait to see how quickly the house sells and for how much. What’s the chance the new owners will require maintenance help? It would be fun to work here again.

 

 

SOL garden opens at Douglas College

By | Education, Events, gardening | One Comment

The SOL (Sustainable Outreach Learning) garden at Douglas College in Coquitlam is now officially open. The creation of  new gardens is always good news! I attended the June 20, 2016 official opening of the garden. Free refreshments also helped after a long day at work.

 

IMG_4924edit

 

Built one year ago, the garden was officially opened after speeches and grass ribbon cutting. It features research beds and native planting at the entrance and on the edges. How many native plants can you name? I spotted Gaultheria shallon, Rubus spectabilis and Polystichum munitum.

 

IMG_4948edit

This ribbon almost required power shears

 

IMG_4957edit

How many native plants can you name?

 

The key point is emphasis on beneficial insects. I love plants and openly confess to outrageous ignorance when it comes to insects. I know bees are fuzzy with friendly faces; wasps are smooth with mean faces. I have lots to learn. But I know how important pollinators are. They are responsible for pollinating something like 80% of the food we consume. We must therefore care for them by providing food sources and eliminating harmful chemicals.

One interesting research plot is full of nursery cultivars which lack pollen and nectar. The insects are tricked but not for long. They know what the good stuff tastes like and fly off to search for it.

The garden is located on the south side of the Douglas College campus in Coquitlam. Feel free to visit. Check for ripe strawberries and study the plants. The college has a gardening club you can join, you can volunteer and, if your pockets are deep, you can donate cash. Cash is required for tables and a storage shed.

I saved the best for last: there are plans for seminars and educational programs which is very exciting. For now, you can pick up handouts on insect and plant identification.

European chafer beetle battles: busy June

By | Education, gardening, Lawn Care, Strata Maintenance | No Comments

June is a busy month for the European chafer beetles. I was thinking about it this past weekend as I finessed beds for a client. Instead of grubs, I was uncovering adult beetles. Some were spent and some just played dead, then made a run for it.

 

IMG_5049edit

European chafer beetles on a Hydrangea leaf. Only the top beetle is dead, the other three played dead and then made a run for it!

 

The beetles mature and emerge out of the ground; most likely out of your damaged lawn. Then they fly into nearby  trees to mate and back down to lay eggs. If you’re lucky, they invade your neighbour’s lawn. If you plan to defend your lawn with nematodes, pay attention to the timing.

Nematodes

In late June the beetles lay eggs and by mid-July nematodes should be available. They must be applied to your well-watered lawn, preferably on a rainy day. The recommended nematode species is the “seeker” Nemasys G. Nematodes work but they are not selective. They hunt down beneficial grubs as well. The other problem is that you might have to re-apply the nematodes again next year. Cut your lawn higher and baby it with proper watering and fertilizing.

 

Fabric alternative

But what if you don’t feel like applying nematodes to your lawn? One alternative I have seen is breathable fabric used in agriculture. It makes it difficult for the beetles to stick their bottoms into your lawn and lay eggs. Pin the fabric to your lawn at this critical June stage, store it and re-use it next year. In the example below the fabric cost was around $250.

 

IMG_5002edit

 

IMG_4996edit

 

Seed alternative

Another alternative is using a different seed mix that will make your grass less appetizing. One test I am involved with involves “Chafer-resistant” seed mix with tall fescue grasses and 2% micro-clover. Warning: the micro-clover will produce white flowers and attract insects to your lawn. At $110+ for a big bag, it will also cost you.

 

IMG_4566edit

We are testing this seed mix on one site

The European chafer beetle battles aren’t going away anytime soon but we can fight back with alternatives.
