'Plasmo Let Down'

I have been excited to write you this month as May is THE gardening month of the year, certainly where planning and planting are concerned. It is the one month of the year when we can plant winter hardy stock like trees and roses (the first half) and frost tender stuff like tomatoes and petunias (the second half, unless you live in Newfoundland - God bless all of you).

Which brings me to point #1. Impatiens (the flower, not the lack of patience that we all experience from time to time) are under siege. Every corner of the country is susceptible to the pathogen Plasmopara obducens, which causes downy mildew.

If you planted some impatiens last year, as I did, and found yourself wondering why they never grew much and why the runts that sat in the ground all summer finally keeled over in late August you have experienced "Plasmo let-down" (I made that up).

Our first response is always to seek out a solution. Surely in these times of optimism and hope and sophisticated scientific answers to most of life's vexing problems there is a whammy that will save our precious impatiens.

No.

This is not a new problem and nor is it exclusive to our part of the world. My British gardening magazines have been talking about it too, and even there, where people would rather garden than eat, there is no solution.

The next question is 'what else can I plant that will give me a great show of colour in sun or shade that I got from impatiens?' I can provide an answer to this one. Here is my list of plants to consider for those places in your garden that are protected from the wind, demanding an eye full of colour and are generally considered low maintenance:

Tuberous Begonias. I know, they have been around a long time and they are not new, but the Non Stop begonias do get better each year. The rose shaped flowers that hang on the strong, fleshy stems provide a show like no other. What they lack in fragrance they make up for in their exotic, hollyhock-like flowers and plugged in colours.

Fibrous begonias. Troopers. They will not let you down in sun or part shade, they bloom all season long, the leaves are a lovely glossy green or bronze and they are inexpensive (like impatiens!). Make sure that you plant in well drained soil and put some diluted 20-20-20 on them from time to time to keep them growing at their optimum.

Angel Wing Begonias. They grow taller than the other begonias but they are great garden performers and container plants. Squeeze a couple of them into your window boxes or moss lined hanging baskets and you will have a rich show worthy of downtown Victoria, where they really know how to mix it up!!

Other colourful annual plants that thrive in the shade include dusty miller, browallia, coleus (look for King Kong for a giant of a winner).

Perennials that make great groundcovers in the shade include pachysandra (Japanese Spurge) hardy to zone 4, vinca periwinkle which is hardy to zone 3 and lily of the valley which is hardy to zone 2. Hard to miss with any one of these.

 Best Tomatoes
 

Tomatoes I grow 200 tomatoes each year. Last year was my best year ever in the tomato patch largely due to the love and attention heaped on my crop by Zac, an intern student from the University of Guelph. Zac worked for me last summer and he poured his heart and souls into my tomatoes. Here are his secrets:

1. Buy short stocky plants with deep green leaves (not yellow)
2. Prepare the soil with bushel of 70% compost/30% sand mix or 'Mark's Choice Vegetable soil' (Home Hardware)
3. Plant up to the first set of true leaves (the stem will make roots of its own) and put the shell of one whole egg in the bottom of the hole.
4. Stake each plant with a spiral stake to eliminate the need for tying them up. When you get your tomatoes off of the ground you double the crop
5. Water deeply and only once a week, once established.
6. Mulch with 40 to 50 cm of straw or 8 cm of finely ground up cedar bark mulch.
7. Spray beginning in mid June every 2 weeks with Bordo Mixture. This prevents early and late blight - the biggest problems of all with tomatoes.

Harvest often to keep the fruit coming.


 


 Emerald Ash Borer
 

TreeAzin If you have an ash tree on your property and you live anywhere in southern Ontario or Quebec you can count on losing your tree to the Emerald Ash borer within the next 3 to 5 years. However there is a treatment that many (smart) municipalities are using to save their valuable ash trees. It is called TreeAzin and it is a biological (read: safe).

TreeAzin has to be applied professionally as it is injected into the tree. Trees need to be treated once every 2 years for 3 to 4 applications. Call a local tree professional for a quote. The product, which was developed in cooperation with the federal government, is a derivative of the Neem tree, native to southern Asia. The cost of treatment of a mature ash over the 3 or 4 applications is about the same as the cost of cutting down the tree and replacing it with a young one.

I am having the 40 ash trees treated on my property. Given the investment that I have in the trees to date, it is worth it to me if it saves them.

From my point of view this is a no-brainer. If only more municipalities agreed. Go to this article that I wrote for the Toronto Star for more details.

As a matter of interest, the students at Elora Public school in Elora have raised over $4,000 to treat the valuable ash trees in their town. The municipality has not set money aside for the EAB yet but we are hoping that they follow the lead of the students. I have no doubt that the same politicians will find funds to cut down dead trees on town property when the time comes, the cost of which will be no greater than the treatment to save them in the first place.

 Buy in Doses
 

Garden Centre As you wade into the intense shopping environment of your favourite local retailer this month let me suggest that it is in the best long term interests of your personal success to buy plants in small batches and return to the store frequently. Plants that you bring home and do not plant for a few days should be stored on the north side of your house or garage and watered before they become too dry. For best results, use 20-20-20 water soluble fertilizer to keep the plants wet and apply again at the time of planting.

Buying in small batches only makes sense when you are certain that there is a reliable supply of plants when you need them.


 


 Golfgreen
 

CIL Golfgreen My friends at Home Hardware have been running lots of TV ads about the new, exclusive formula of Golfgreen lawn fertilizer this time of year. The ad features a guy pushing a spreader, talking about the gorgeous lawn that you can enjoy with this magic elixir of a Canadian made product.

This raises the question that I am very often asked: "What is different about the formula that you are peddling for Home Hardware?" Answer: more nitrogen.

To the point "more slow release nitrogen". There is 5% more of this amazing stuff in each bag vs. the 20-0-5 formula that you find at other retailers. Your lawn craves nitrogen this time of year more than any other element.

If you dream of a great looking lawn without a lot of work I urge you to try this formula of Golfgreen 3 times this year, to cut your lawn at least 2 inches high and to water no more than once a week. Pull lawn weeds with a Mark's Choice 'Speedy Weeder' and where thin patches occur lay down 5 or 6 centimeters of Mark's Choice lawn soil, spread Golfgreen grass seed, rake smooth, step on it and water well.

You can fertilize the same day that you spread grass seed.

Reminder: you receive a free copy of my new book Canadian Lawn and Garden Secrets when you buy two 6 kg bags or one 12 kg bag of Golfgreen at Home Hardware. A $12.99 value.

 Featured Product of the Month
 Bobbex Deer Repellent

Bobbex Bobbex is an effective foliar spray used to deter and prevent deer and other wildlife from causing damage to ornamental plantings. It repels by both odour and taste by using meat meal, fish oil, eggs, garlic and other natural ingredients. The distinctive smell warns wildlife that area has been treated, and the burn of cayenne, though not harmful, gives them a reminder not to eat any of the sprayed plants.

Bobbex can be used all year. The use of Bobbex should be increased in Spring due to the rapid growth of plant material. Spray every 10 to 14 days to protect new growth as it appears.

Apply Bobbex in the early morning hours rather than the 'heat of the day'. Use on all types of ornamentals, trees and shrubs. Bobbex should not be used on food plants when fruits, vegetables or herbs are developing.

Squirrels napping I built 2 wooden blue bird boxes with my buddy Larry's son, Ryan. He took them home proudly and with some help from Dad mounted them on their ash tree.

They apparently make a great place to nap if you are a squirrel.

 LEAF's Subsidized Backyard Tree Planting Program
 

LEAF This program is available to all Toronto residents. The goal of this program is to plant over 2,500 native trees and shrubs in backyards in 2012.

LEAF provides a backyard consultation to help property owners select the right native species and planting location for each yard.

Property owners pay a subsidized cost of approximately $100-$200 per tree. This cost includes a consultation with an arborist, a tree and full planting service.

Property owners who request a consultation in the next two to three weeks can still expect a Spring planting. Those who contact LEAF after that will get a consultation right away, with the planting taking place in the Fall.

 Are Geraniums the Answer to the Japanese Beetle Question?
 

Geranium At a recent speaking event I received an interesting tip. A number of gardeners have had success controlling Japanese Beetle damage by planting geraniums!

"Japanese Beetles aren't particular about their diet but are, apparenelty, drawn to geraniums. Their digestive system is somehow not compatible with this diet and there is something in the geranium flower that casues a lenthy paralysis. During the time of paralysis they are not able to evade predators. The beetles are apparently more drawn to white geraniums but any colour of geranium flwer will work. "

I admit that I have not tested this theory. But I think it is worth a try this season. Let me know if this works for you.
