Planting a Flower Patio Container - Things to Consider

by Pat Freistatter

Location of Container

• Sunlight - how much sunlight will the container will receive – afternoon sun is hottest - choose plants for those light conditions

Viewing Container

• larger leaves with coarse textures and tall spiky grass can be viewed from a distance and make a visual statement
• fine textured plants invite you to look more closely at the detail
• a taller pot may be needed if you want the flowers to be viewed from afar

Container Size and Material

• Container needs to be big enough to hold enough soil for the growing season
• Fiberglass or plastic pots do not dry out as fast as clay and other porous containers.
• Three to seven 1 cm holes need to be drilled into the bottom of container for adequate drainage.

Soil Mixture Contents

• Materials such coconut husk fiber and sphagnum peat moss help retain water
• Black earth (humus), composted manure, perlite, lime, and fertilizer support plants throughout growing season.

Colours and size of plants

• White flowers catch your eyes and help other darker colours jump out
• A variety of leaf shapes and sizes increase drama and interest in your pot

Plant soil and moisture requirements

• All plants in container need to have same moisture requirements – don’t mix plants that like dry conditions with those that prefer wet feet

Structure

• Thriller – tall centre
• Filler – plants around thriller
• Spiller – plants that spill over the edge of the container

Note: if the back of your container will be up against a wall, then the taller plants should be at the back

Container Maintenance

• Check planter daily to ensure it doesn’t dry out
• Fertilize container every couple of weeks with water-soluble fertilizer
• Remove dead flowers to encourage re-blooming.
• Empty and wash out containers at end of season

Growing Strawberries in Containers

by Pat Freistatter

Why grow strawberries in containers?

• It does not require a lot of space.
• Containers can be close to your kitchen
• Bacterial and fungal diseases and damage from slugs are reduced.
• Containers can be moved around to take advantage of warmth and light from the sun.
  

Note: Strawberries on plants still need to be protected from Insects and birds

What type of strawberry plant grows best in containers?

• Any type of strawberry plant can be used.
• June bearing strawberry plants provide one large crop.
• Day neutral strawberry plants produce fruit throughout summer, except during hot weather.
• Ever-bearing strawberry plants produce 2-3 harvests each summer from early spring to fall.
  

What type of container can be used?

• Many types of containers can be used: eg. hanging basket, pot, wooden box (must have several drainage holes in the bottom)
• Strawberry plants have a small and shallow root ball so they can be grown in small containers; as small as 25 cm in diameter and 20 cm deep (Note: small containers must be watered more often)
• Light coloured pots keep the plant roots cooler in the heat of the summer.

What type of soil should be used?

• Use loose, loamy potting soil that will hold water, but allow excess water to drain away.

How do you plant the strawberry plant?

• Fill the container with potting soil to within 2.5 cm of the rim
• Put plant in pot and cover the roots, up to the crown (where the leaves emerge), with the soil and water well. Add more potting mix if needed after the soil settles.
• Strawberry plants can spread out about 60 cm – put only 1-- 2 plants in a small container.

When should the plant be watered?

• Water strawberries whenever the soil feels dry to about 2.5 cm below the surface.
• Avoid both soggy and dried out soil.
• Daily watering may be needed in periods of hot, dry weather.
• Keep moisture off the leaves to prevent fungal diseases that will damage the fruit.

How should the plant be fertilized and when?

• Strawberries should be fertilized every 3-4 weeks, as soon as the first flowers appear, with a fertilizer high in phosphorus.

How much sun should the plant receive?

• At least 6-8 hours of sun – rotate container every 3-4 days if possible

After Bloom Care Of Spring Bulbs

by Deb Gordon

Nothing signals the rebirth of a garden more to a gardener than the first splash of colour from spring bulbs. The fresh green colour of their leaves and their colourful palette of blooms are a welcomed sign of the departure of winter and the awakening of life in the garden with all the hope and expectations that they may bring. Be it tulips, daffodils, hyacinths, grape hyacinths or alliums these early bloomers all have one thing in common. They are all true bulbs and being so means their continued lives depend on letting them become dormant through the cold winter, allowing them to bloom in the spring and die back naturally in order to complete their life cycle. This ensures the bulb's good health so it has the ability to endure freezing temperatures throughout the winter, produce optimum blooms for the gardener to enjoy the following spring and continue to do so for years to come.

The only drawback for growing these bulbs is waiting for the leaves to die back. Unfortunately it takes weeks for their leaves to wither and die. Especially with larger leaved bulbs like tulips and daffodils, the appearance of their dying foliage, long after the blooms drop or fade, can detract from the beauty of an early summer garden. Premature removal of the foliage is tempting in order to keep the garden neat and tidy however there are consequences to doing so. Take tulips for example. They grow and bloom using the food that they have stored in their bulbs from the previous year. Once this food is spent, the bloom drops and the foliage starts to die. During this post-bloom phase, the leaves, through photosynthesis, produce the food that is stored in the bulb to enable it to survive the winter and grow and bloom in the spring. Photosynthesis is a process where the energy in sunlight is harnessed and used to convert carbon, oxygen and water into sugars. Because leaves of all plants are the primary location for photosynthesis to occur, cutting off the leaves prematurely deprives the plant of the ability to restore the energy in the bulb for its future healthy growth and its production of those beautiful blooms.

So what are some of the options for a gardener to choose in order to keep a  more pristine-looking garden.

When blooms start to fade and petals drop, tidying up the garden at this time is easily accomplished by cutting off the stems of the flower. This will still allow the leaves to continue to absorb the sun's rays. The time is right to remove the leaves once they have withered, turned brown and can be tugged gently away from the bulb. Wait another week or two if they are not separating from the bulb easily.

The following suggestions may help to avoid the distraction of the dying foliage.

• Dig up the bulbs and replant new ones in the fall. This can be costly in time and money. This is done routinely in publicly sponsored gardens.
• Transplant the tulips post-bloom to another bed to live out the foliages' dying days then replant the bulbs in the fall. This requires an extra bed just for this purpose.
• Choose a variety that have narrower leaves which might be less distracting.
• Conceal the withering leaves.

Strategic planting of the right combination of perennials around your bulbs may be the answer to successfully camouflaging the unsightly foliage while still allowing them to complete the restoration of energy in the bulb undisturbed for next year's growth. Annuals and summer blooming bulbs are also other options. When choosing perennials to use, consider the rate at which the plant matures. You want the bulb to be centre stage while it's in full bloom, the perennial just starting to appear above ground and then mature as the tulip leaves start to yellow and wither.

Although the rate of maturity is important, also consider foliage type, colour, and bloom times when choosing these perennial plants.

Hostas, tall drooping grasses, and taller ground covers are examples of perennials that are idea lfor concealing a tulip's dying foliage. Remember that placement is key. If you are planting bulbs in the fall around hostas, make sure you plant the bulb just inside the dripline of the hosta just under the leaves. Bulbs go in front of the drooping grasses.

There are combinations of perennials listed at Cornell University's website
http://www.hort.cornell.edu/combos

Researchers at Cornell University actually tested and listed plant combinations to see which were successful at looking good and growing well together. They have great photos of these plants and bulbs at different stages of their growth.
Just remember to check the hardiness zone and growing conditions of some of the suggested plants (if choosing) to ensure they will grow in your zone and growing conditions. The research took place in Ithaca, New York with a USA hardiness zone of 5.

If you've been discouraged from growing or adding more spring blooming bulbs to your garden due to the lingering foliage that never seems to go away, these suggestions will hopefully encourage you to do so. The early visual impact is rewarding and will trigger feelings of hope and excitement of the wonderful things to come.

The Garden Show Receives Two Prestigious Awards

GARDENS and GARDENING EXPERIENCES


Gardens and garden experiences are cultural treasures that have intrinsic value in our communities. They define our quality of life and are spaces that support communities. They are strong economic engines that incite and share passion because - Nature connects us. We care where our food comes from which encourages us to grow our own and share it with others. We care how our neighbourhoods look which encourages us to create beautiful gardens, sharing that beauty with others. Gardeners pursue exploration, education and excellence in creating magic in both public and private spaces and spread that passion.

As Henry Ford said:

“ Coming together is a beginning; keeping together is progress; working together is success”.

This is what gardeners do in their own gardens and within the garden experiences they share with others.

The Peterborough Garden Show is one of those magical places that local gardeners generously share with others. Organized and run by volunteers from The Peterborough Horticultural Society in collaboration with the Peterborough Master Gardeners, it showcases 150 vendors, professional speakers and displays to tempt, educate and incite passion.

It is for these reasons, this show has been honoured with two prestigious awards at the 2017 International Garden Tourism Conference in March.

Garden Event of the Year and,

one of 150 Garden Experience Designations in Canada.

Plant Watch

by Cauleen Viscoff (previously published in the Peterborough Examiner)

Now that the weather is softening, and we are convinced that spring really is around the corner, there are reasons to herald its arrival other than with Easter eggs, birdsongs and flowers to pick.

There is a little-known group of folks around the world who are quietly making a difference. They are monitoring birds, insects, frogs and plants. Recording the blossom times of some plants are good indicators of climate change. We all know that our climate is making some subtle as well as some not-so-subtle changes - some better and some not so much. So what does watching plants have to do with climate change?

Plant-watching has a long tradition and a rich history throughout the world. In 1750, the Swedish scientist and artist Linnaeus, turned plant-watching into a systematic science. He made calendars of flowering times for 18 places in Sweden, noting the exact climatic conditions at the time of blooming.

This became the foundation of modern plant phenology (the science dealing with the influence of climate on the recurrence of such annual phenomena of animal and plant life as budding and bird migrations- Dictionary.com). Phenology then spread to many European countries and revealed, over the centuries, that some spring wildflowers are super-sensitive weather instruments.

More than 100 years ago in Canada, Nova Scotia's superintendent of education, Dr. Alexander H. MacKay, had students collect plant, animal, agricultural and weather phenology from 1897 to 1923. And then, in 1987, the Alberta Wildflower Survey started up and blossomed (pun intended) into a program that initiated the Alberta PlantWatch. This program then spread back to Nova Scotia, Newfoundland and now today, PlantWatch is part of our national Nature Watch series of volunteer monitoring programs designed to help identify ecological changes that may be affecting our environment.

There are PlantWatch programs in each province and territory.

PlantWatch enables "citizen scientists" (volunteers gathering research for scientists) to get involved by recording the flowering times for certain selected plant species and reporting these dates to researchers on the PlantWatch website. When the data is submitted electronically, it is instantly added to web maps showing bloom dates all across Canada ... So those observations make a difference right away!

The collection of that much data across the vast expanse of our country would be impossible for the small existing group of scientists presently working in this field.

As Canadians, we are fortunate to live in a country with such a wide variety of plant species. By participating in PlantWatch, we can learn about our country's great botanical diversity and at the same time, help scientists track the effects of global warming and climate change in Canada.

The plants chosen for this program bloom every spring, largely in response to rising temperatures. However, some species are flowering almost a month earlier than they were a century ago!. Some of these plants you are familiar with and grow in your own yards and gardens. Poplar, Common Purple Lilac, Dandelion (bet you have lots of those..), Red Maple and Trillium are just a few.

Scientists believe that climate change is affecting bloom times - a trend that is continuing. They predict that the greatest increases in temperature will be in Western and Northern Canada, while some parts of Eastern Canada may actually be cooling (although last summer was hotter than ever).

By reporting on the PlantWatch species found in our local communities, we can help researchers discover how common plants are responding to climate change, and track where those changes are taking place in Canada and at what rate.

And now, for the first time in Canada, the PlantWatch program has partnered with the Master Gardeners of Ontario. We are excited about our potential contributions to science because we believe that observing local plants can be fun, but more importantly, the data we collect can serve a greater purpose by assisting scientists, land managers and those responsible for our natural resources to help in the environmental decisions they will need to make both now and in the future.

We urge you to join us in making a difference. You don't have to be a professional, or even a gardener.

Take a look at the website; the plants are described in detail with glorious photos. Gather up your your children, grandchildren, friends and neighbours - sign up, get outside and watch spring happen - make your observations and"¦.make a difference.

2017 Perennial of the Year - Asclepias tuberosa

by Anne Milne

The Perennial of the year for 2017 is the Asclepias tuberosa, or as most of us know it, Butterfly Weed.

Butterfly weed is a hardy perennial that grows from 1/3 meter up to 1 meter (12 to 36 inches). It is a relative of milkweed, and is non-invasive. Butterfly weed is native to eastern North America. Its hardiness zones are 3 to 9.

Butterfly weed grows in clumps and produces orange or yellow clusters at the top of its stems. Blooms last from early summer to early fall. Keep the plant dead-headed to encourage reblooming. This plant likes full sun, and medium, well-drained fertile soils. It is drought tolerant, thus it does not like to be overwatered or overfertilized. It is also resistant to deer!

Butterfly weed attracts butterflies, and is also very attractive to humming birds, bees, ladybugs, and other beneficial insects. Monarch butterflies lay their eggs on the plant and the larva feed on its leaves. Monarchs also depend on its nectar as a food source.

Asclepias tuberosa can be grown from seed. Plant seeds in spring, after frost. Plants from seeds will likely not bloom for 2 or 3 years. Butterfly weed plants are also available at most reliable nurseries. Aesclepias tuberosa will also reseed itself. The seed pods will burst and float around your garden to start new plants.

Butterfly weed has few problems, but may have aphids or mealybugs. Because this plant is so vital to our Monarchy butterfly, rather than using pesticides, use your hose to spray and dislodge the pests from the plant.

Grow this plant in bunches, along with butterfly bush, bee balm and cone flowers, and you will make an outstanding display.

Victory Gardens for Bees

by Christine Freeburn

It was a very nice surprise to find in my local library, a new Canadian gardening book with a timely subject matter. Lori Weidenhammer, author of Victory Gardens for Bees published by Douglas & McIntryre, is a Vancouver based artist and educator actively involved in making Canada and the world a better place for humans and bees. This volume is beautifully illustrated with full colour photographs, seasonal planting charts, illustrated garden plans and historical facts about the original Victory Gardens. It is the type of book you can read chapter by chapter, use as a reference book or flip through for random information.

Chapter one describes the Colony Collapse Disorder, explaining that the 20,000 different species of bees worldwide are in serious danger. Currently there are 57 bee species on the endangered list. Weidenhammer gives us a clear history of what has happened over the past ten years. She suggests a bee wise program similar to the ocean wise system where we, as consumers, buy only from responsible sustainable-conscious growers and producers.

In chapter two, the author gives us the history of the original Victory Gardens along with garden plans for several bee friendly gardens. She lists sixteen essentials to creating a safe garden space for bees. By letting a few of your vegetables and herbs bolt, you will allow bees to enjoy the pollen from these plants. Did you know that 70 % of bees nest in the ground? Another reason not to dig!

Chapter three shows us some of the bee species that visit our gardens. It is well illustrated, easy to read and gives the reader so much good information about the many types of bees. After reading this chapter you will be eager to try to identify the bees in your garden.

In the following chapters, the author discusses growing specific herbs, vegetables, trees, shrubs, bulbs, perennials and annuals for a bee friendly garden. She talks about hedgerows, pastures, traditional gardens and container gardening. Each chapter has lovely photographs, charts and tips. We learn about bee habitat and how to create homes for bees. Did you know that a stumpery is an ideal spot for bees to nest and it can also be garden art?

There is also a chapter on beekeeping and the importance of having enough food for native bees as well as hive bees.

The final chapter sums up the importance of getting all generations involved in gardening, again referencing how during the world wars, Victory Gardens drew families and communities together. There are common sense tips on how to avoid bee stings, a reminder that solitary bees do not sting or sting very lightly. Weidenhammer encourages us to become bee guardians and to 'Dig for Victory!'

An index at the back, allows the reader to look up by plant or bee species. A list of sources gives you places to obtain more information and the end notes add more information.

Lori Wiedenhammer has given us a well written, beautifully illustrated, informative resource that is timely, inspirational, Canadian, and deserves to be on any concerned gardeners bookshelf.
