Urban Tree Issues by Bill Dowie

Jensen Nursery can solve your urban tree issues...

If you think you do not have enough room in your smaller urban space for trees, think again.  There are a number of workhorse trees 
that Jensen's has in stock that can you can shoe horn in a corner or start creating that living screen that you always wanted (you 
know, that new neighbor just built a raised deck, and now sees your every move!).

Going into June Jensen's will be looking at what else to order for you collectors, but in the meantime here are four great trees of 
different genus (dimension are average height and width):

Malus - Thunderchild Rosybloom are 16x13 feet with a nice vasing growth habit that can act as a great screen in a medium space; the 
new Gladiator is even narrower at 10' wide; of course, there are the old standbys of Radiant, Fushia Girl, and Pink Spires - all will

not exceed a two story house.  Learn about some pruning techniques to shape your small trees in March of every year, and a way you 

Syringa - The Ivory Silk Tree Lilac is on its own trunk and is a true tree form (not the lollipop standard).  It will bloom in later 
June after all your shrub forms have lost their flowers, and is a nice 23x16 feet with off-white flowers and dense leaf and branch 

Prunus - The Amur Cherry, along with the purple foliage of a Rosybloom, will be a great tag team to replace all those dying Schubert 
Chokecherries with Black Knot.  At 30x23, it is the larger of the small urban trees, will grow a nice umbrella canopy if you let it -

though a multi-trunk form is a nice addition - and has gold-brown-bronze exfoliating bark.  A super tree for winter interest.  The 
berries will attract migrating birds in the fall, when the leaves blaze in reds, oranges, and purples.

Well, this is the time for planting – finally!!!

We must remember to get our plants ready for the great outdoors where they will be subject to the elements of the season.  Most plants at many greenhouses and different places have been babied and have not been used to the wind and the direct sun. To make sure your plants are going to survive and be healthy and strong, put them first in a shady, sheltered area and then gradually move them into the sun and the wind for a few hours at a time.  You may have to do this for a few days before planting them out into the garden area or will they will eventually call home.  They will need a lot of water for the first while they are out so they don’t dry out and get stressed.  If they look wilted or the leaves become white (scorched by the sun), give them a good drink and move them back into a sheltered, shady area for a few hours before you move them back out again to where they will be planted.  If you have already planted them out into the garden area, you may have to shelter them from the hot sun and wind by using sheets, newspaper or cardboard boxes to cover them.  Plant out your sun plants first and then your shade plants.  If the temperature drops below 10 degrees at night, your shade plants may suffer and become stressed, so if you have a lot of planting to do, leave your shade plants until the temperature at night is 10 degrees or higher.  If you are planting your containers, the ideal time to plant is in the early evening.  They will then get the rest of the night to settle in before the hot, windy conditions of the day.  For the first week, just make sure everything is well watered and then after the first week once they are settled in, start your fertilizing program.  Most plants purchased have little to no food in the soil less mix they are grown in, so you must improve the soil with compost or fertilizer of some kind.  For blooming plants, I recommend a water soluble fertilizer with a high middle number to encourage bloom.  Miracle Gro 15-30-15 is a good one to use.  A fertilizer too high in nitrogen, the first number will encourage a lot of leaf, but little bloom.  If you follow this simple plan, you will have strong, healthy plants that will ward off a lot of insects and give you a lot of bloom throughout the rest of the summer!

May Long Weekend - Planting time is here!

Well it's that time again! Typically it should be safe to plant annuals after the may long weekend. I've also heard after the first full moon in June! This year people have been planting for about 2 weeks already! I have to admit I did a container with a false banana plant, licorice plant, calabrachia, and black eyed sue vine about 1 1/2 weeks ago. Two nights ago we had a low of 1 degree. My container survived! I had planted using "Myke" to get the root going fast! People have been asking me for 2 weeks if it safe to plant. My response is always the same - "Well it is 25 above and beautiful - BUT this is Winnipeg and the weather can change in a second." Waking up yesterday and finding out the temperature dropped to 1 degree just confirms it! So plant away - but please check the forecast! Just a little frost can kill a annual. The perennials, shrubs, and trees can handle it now.
We expect to be very busy at the garden center this weekend. I apologize in advance if we do not get to all the phone calls. I have been trying after hours to catch up all the phone messages - but this weekend it will be hard. Send me a email at tammy@jensennursery.com and I will see it on my blackberry and I can send back a quick answer!! We just received a truckload of plants last night - I recall seeing Topaz Jewel Rose, Champlain Rose, Fireglow Rose, Pavement Roses, Mohanican Viburnum, French Lilacs, Lilac and Caragana Standard, Trail Applecrab, Pagoda Dogwood, and Ivory Halo Dogwood to name a few! I am expecting a truck load of annuals today - petunia's, toamtoes, vegetables, herbs, ageratum, alysum, aster, begonia, cosmos,caster bean, coleus, datura,dusty miller, gazinia, impatience, kale, lavatera, lobelia,marigolds, morning glory, nicotina, nierembergia, petunia, portulaca, salvia, snapdragons, vinca,zinnia, blackeyed sue vine, euphorbia, sweet potatoe vine,osteospermum, geraniums, spikes, nemesia, and mandivilla vine. Just to name a few!!!! Gerald Lacoste will be sneaking all the fancy "oddball" as he calls them variety's in the back door as well!!!
Well I have a busy day ahead sorting out 300 plus flats of new annuals! I expect they should arrive by mid afternoon! So see you in the greenhouse!
Happy planting!

Container Gardening - Drop by and we can help you today with your containers!

Container Gardening

Before you start:

Change the potting mix every year. A basket/container mix works best. By the time the season is over, all nutrients in the mixture will have been used up. Recycle used potting soil in your compost or work it into existing flower beds.

Picking your plants:

Think about where the container will be placed and select plants that require similar growing conditions (such as full sun or shade, moist or dry soil, sheltered or not), yet have different growth habits and bloom times. For high-traffic areas, consider adding fragrant foliage plants such as lavender, thyme and rosemary.

Thrillers, Fillers, Spillers 

These three words, coined by garden designer Steve Silk, capture the essence of good container design. In the artful container, anything goes.
Foliage only, or a mix of annuals, perennials, shrubs, herbs, summer bulbs, ornamental grasses, small evergreens, vines and tropical plants are all appropriate. It's entirely your choice.


The tall, upright, eye-catcher placed either in the centre or off-centre in the container; plant it first. For a tropical look  try cannas, coleus, or Palm Grasses.  Ornamental   Grasses of all kinds make great Thrillers.  Decidious or evergreen shrubs also work great.

Try using roses, a small Japanese maple, an azalea standard or your favourite shrub or evergreen as the star of your container. In the fall, remove perennials, trees and shrubs from containers and plant them in the garden three to six weeks before the ground freezes


Take up mid-ground space without distracting from the thriller. Begonias, lantanas, salvias, parsley, low-growing grasses and numerous other foliage and flowering plants fall into this category.


Plants that flow over the edges of containers: sweet potato vines (Ipomoea batatas), ivies, trailing geranium,  petunias, Bacopa and Bidens  and no doubt many more discoveries you'll make at your local garden centre.

Getting Started
•First water all plants in their cell packs or store-bought pots.
•Fill your pots with a special container potting mix such as Smart Mix.  These mixes are specially formulated for your containers.  Leave five to eight centimetres between the top of the soil and the rim of the container to allow water to slowly penetrate the root system rather than run off the surface.
•Add a tablespoon of slow release fertilizer and mix into the upper part of the soil.
•Water the soil mixture.
•Arrange your plants and plant them at the same depth they are currently at in their cell packs
•Give the container one more watering.

•If the mix feels dry to the touch approximately one inch below the surface, then it is time to water your container garden. 
•Due to the amount of water that container gardens require it is a good idea to fertilize them on a regular basis with a water soluble fertilizer such as Ultrabloom at least once every two weeks.
•Caution should be exercised to prevent over watering, which can lead to root rot. Gardeners should also keep in mind that plastic containers will fade in the sun. Therefore, placing colored plastic containers in a shady location will promote a nice appearance for a longer time.
•Removing spent blooms will encourage the growth of new blossoms. This will keep your flowers looking colorful throughout the season.


If you need help designing your planter - drop by with your pots and we can help you pot it up at our container gardening area! On fridays from 9-5 Arlene Wheeler is in just to help you with your containers. We have a great selection of containers to pick from if you need new ones!
