Invasive Plants…and Worms

Colin Cassin, Policy Manager at Ontario’s Invasive Species Centre was the guest speaker at the Tweed and District Horticultural June meeting. He discussed earthworms, jumping worms and other garden invasive species.

Through his power point presentation, Colin provided the members with an overview of the many invasive species in Ontario….and Ontario is the leader in Canada to have the most invasive species… 440 invasive plants, 38 forest insects, 10 tree disease and 180 non-native species!! Invasive species spread through birds, wind, people, animals, plants…almost anything.  From a financial viewpoint, it is better to stop the establishment of these invasive species before they get out of control.

It was interesting to note that of the 19 species of worms in Ontario that are invasive only 2 are not. As Colin said, “worms are small but mighty”. They can change the soil type, change what plants grow in an area and that leads to affecting the wildlife that lives there. Since most worms live underground, we do not see them, but they are there creating issues.

Jumping Worms do NOT jump; they thrash and move very quickly hence the name Jumping Worms. There has been sightings of them in the GTA, Windsor and recently in Perth (2023) They are considered an annual worm in that they hatch in the spring from their cocoon and grow to maturity by late August/September. One way to identify them is that the ring around their neck is flush with their body which is different from other worms. As Colin stated, the Centre does not have perfect handle on this species at this time.  

Colin touched on invasive plant species to be aware of when shopping at garden centres and plant sales. The issue with invasive plants is that they spread and grow in natural landscapes blocking other native plants and wildlife from growing.

Colin provided suggestions to help control invasive species…. commit to planting non-invasive species, limit the movement of plants and soil, do not accept invasive plants at local plant sales, incorporate the words “invasive” and “non-invasive” into your gardening vocabulary.

In summary, Colin said it is necessary to slow down the rate of spread of any invasive species (plant, insect, tree).  If this is not done, the effect will be devasting and costly over time.

Native Plants and Insects

“I thought native plants were weeds.” “Such an informative and inspiring presentation!” “I don’t want golden rod in my gardens as it causes hay fever.” “After listening to Lorraine’s presentation, I intend to get some native plants for my garden.”

These are a few of the comments that were heard following Lorraine Johnson’s presentation at the May meeting of the Tweed and District Horticultural Society. Lorraine is a writer, editor and advocate for the natural world.  Her presentation provided practical information about how to create a welcoming habitat for bees, butterflies and birds. She also explained the truth behind several age-old myths about native plants. 

According to Lorraine, a biodiverse landscape is the cornerstone of any garden. In terms of native plants in a garden, it is important to plant a diversity of native species that will provide a succession of continuous blooms from spring to fall. The garden should also include a variety of flower colours and shapes and plant heights arranged in groups of 4-5 plants. 

It was interesting to learn that there are generalist and specialist native bees. The specialist bees have a relationship with certain plants. Generalist bees on the other hand do not have such a relationship. To encourage a certain type of bee to the garden, one needs to plant a variety of native plants that will attract the specialist bees. The top native plants that support specialist bees are goldenrod, sunflowers, coneflowers and asters. 

Butterflies and birds need a welcoming habitat to survive. A garden needs to contain host plants that will support the larva of the different butterflies. And 96% of the birds in North America rear their young on insects found in our gardens!

Simple ways to help support a welcoming environment for bees, butterflies and birds…. reduce the amount of lawn, have areas that are pesticide free, plant diverse flowering species in gardens and under trees, add logs and branches to the garden to create a “stumpery” and leave the leaves as many insects overwinter in them, for example the swallowtail butterfly overwinters as chrysalises in leaf piles. 

Lorraine and Sheila Colla’s book, A Garden for the Rusty-Patched Bumblebee, is an excellent resource for native plants that will help to create a welcoming habitat for native pollinators in Ontario. This resource contains garden designs for residential gardens, community gardens and even a balcony, photos and descriptions of native plants and the pollinators they support and the relationship between native plants and pollinators….an informative guide for all gardeners. 

As Lorriane says, it is up to us to be “pollinator protectors” in our gardens.

PLANT SALE…Saturday May 18 @ 8:00 am at Tweed Memorial Park

MEETING  June 4 @ 7 pm Tweed Public Library.

Growing Succulents

Christene Gilbey, owner of Sun Worshipper Succulents in Belleville shared her love for these amazing plants at the April meeting of the Tweed and District Horticultural Society. As a child, Christene, remembers harvesting “stones” from her parents’ potato fields! Fortunately, this experience did not ruin Christene’s love for gardening. While she was living in an apartment with no yard, she turned to small easy-care succulents. She opened Sun Worshipper Succulents in November, 2020 and has shared her love for these plants with others.

Succulents are perfect plants for small places. 

It is necessary to use a well draining soil mixture. Christene mixes her own soil at her store and this succulent mix, “rainbow mix” can be purchased at her store. The mixture is ½ potting soil and ½ perlite.

For gardeners who forget about watering their plants, succulents are perfect for you! The soil should be totally dry before watering…and if you forget, the plants are very forgiving! It is best to water from the top and try to avoid getting the leaves wet. Do not let the plant sit in water. Christene uses bamboo sticks to test for dryness…if dry, then and only then is it time to water. 

These plants need 6-8 hours of sunlight each day. It was interesting to learn that the amount of water and light can bring out the colour of the succulents. 

No fertilizer is needed…. these plants survive on neglect!

Like all plants, pests like mealy bugs, fungus gnats and powdery mildew can be a problem for succulents. When Christene purchases plants for her store, she quarantines the new ones for two weeks to ensure there will be no bugs. 

Christene enjoys checking thrift shops for containers for her succulent arrangements. Her shop offers a “drilling” service to drill holes in containers using a diamond tip on the drill. That hole in the base of the container is essential for drainage as succulents do not like wet soil.

Although succulents can flower, Christene says the flowers are neither fragrant or outstanding…. flowers fade but foliage is forever!

Members were given the opportunity to “shop” after the meeting. It seems that many members are now becoming “succulent worshippers” just like Christene!

The store, Sun Worshipper Succulents is located at 191 Dundas Street East, Unit # 3. Belleville. Phone: 613-970-1556 email… The hours are Wednesday-Sunday 10-5. 

MAY 7 MEETING @ 7 pm Tweed Public Library

Lorraine Johnson, a writer, editor and community advocate for the natural world will provide practical information about creating a welcoming habitat for insects and other wildlife. 

Some Sunny Succulents

Christene Gilbert, owner of Sun Worshipper Succulents in Belleville, is the guest speaker at the next Tweed Hort meeting on April 2, 7 p.m. at the Tweed Library.

Christene tells us a bit of her story here:

My earliest memory of gardening involved “harvesting” stones from my parents’ potato field. Luckily that didn’t sway me from the love of flowers too.

About 20 years ago I opened Common Scents Garden Consultation where I grew annuals and hardy perennials in my 20X40foot greenhouse. Most plant businesses engage in other winter services in order to have a year-round income. That wasn’t something I wanted to do.  I met my husband, sold the greenhouse and went back to school and obtained my medical office administration diploma. I worked in the healthcare field for many years, but something was missing. I no longer enjoyed the commuting to Kingston for work and longed for plants back in my life. We had downsized to a 2-bedroom apartment and without a yard I fell hard for the small, easy-care succulents that I sell today. The fact that I hate everything “winter” related was the inspiration to name my business Sun Worshipper Succulents.

My past experience includes:

Former Master Gardener- Quinte/Tweed

Past president of the Belleville Garden Club.

Multiple speaking engagements including presentations to both public school and secondary schools, as well as area horticultural groups.

Owner of Sun Worshipper Succulents which I opened on November 6, 2020 which is where you will find me Wednesdays through Sundays 10-5. 

Shoreline Care

Lindsay Nash, Outreach and Stewardship coordinator for Quinte Conservation outlined the responsibilities involved in caring for shoreline properties at the March meeting of the Tweed and DistrictHorticultural Society. Using a power point presentation, Linsday gave members who own land adjacent to lakes and rivers helpful information to maintain a healthy shoreline.

By definition, “shoreline” is the area where land and water meet and this “ribbon of life” is a vital link providing plants and animals the resources they require to exist. It is essential to properly care for the shoreline on the waterfront property. 

One way to do this is by maintaining/planting a buffer zone of native plants, shrubs, trees along the shoreline. This helps to slow erosion, provide food and shelter for fish and wildlife species and protects the landowner’s property and investment.  And a natural shoreline means less work and more time to enjoy its beauty!

Lindsay mentioned several native species that would help with the naturalization of the shoreline…. white birch, sugar maple, red dogwood, wild roses, swamp milkweed, cardinal flower. She provided pamphlets at the meeting that offered numerous possibilities and listed suppliers in the area. She did stress the importance of“biodiversity” in planting to prevent the area from being wiped out completely in the case of a disease.

Waterfront property owners are always concerned with erosion of the shoreline. Any type of construction along the shoreline requires a permit from Quinte Conservation. Repairs to existing rock walls are permitted but construction of new ones is not permitted. For a fee, Quinte Conservation offers a site visit to assist the property owner with the naturalization of the shoreline on their property

For members who do not have property on a lake or river, Lindsay suggested  making a rain garden. Use a mixture of sand and soil to capture the rainwater. Use native plants in the garden that are both drought and water resistant.

As Lindsay said, naturalizing your shoreline may involve some work initially but the rewards far outweigh the work when you can enjoy the beautiful lakefront views from your property knowing that you have protected that “ribbon of life” on your property.

April 2 MEETING @ 7 pm Tweed Public Library

Christene Gilby, owner of Sun Worshipper Succulents in Belleville will discuss the growing and caring of succulents. She will have some plants for sale…cash only.

Gardens Across Canada

Using a power point presentation, Penny Stewart took members of the Tweed and District Horticultural Society on a trip across Canada visiting various gardens throughout the country.  Penny also included the historical background of the gardens she visited. 

Penny Stewart is an avid photographer who has won many design and horticultural trophies throughout her 60 years of gardening. She played a key role in the development of a green garden in front of the Ministry of Environment office located in Kingston. 

The first garden on our tour was the famous Butchart Gardens in Victoria, British Columbia. The gardens provide dramatic floral displays in a variety of garden settings. This garden which has been open to the public since 1904 has been designated as an historical site.

Next stop was the 650-acre Hatley Estate Gardens in Vancouver. This garden is a national historic site which houses hundreds of heritage trees that are known for their size, rarity and diversity. There is a 250-year old Douglas Fir that is among the largest in the area. The formal gardens include the Rose Garden, the Italian Garden and the Japanese Garden. Penny’s photos highlighted the  spectacular rhododendrons in bloom as well as the clematis. 

Nitobe Memorial Gardens are located on the campus of the University of British Columbia in Vancouver, BC. Although small in size (2.5 acres), this Japanese garden is considered one of the top Japanese gardens outside Japan. The peaceful garden has rock gardens, canopy walks and a feeling of peacefulness prevails throughout the garden. And all the shrubs are hand pruned!

Dr Sun Yat Sen Garden is a walled garden located in Vancouver’s downtown area near Chinatown. It was the first Chinese garden built outside of Asia. Rock and stone material was imported from China.

VanDusen Botanical Garden is also located in  Vancouver. The gardens host a mixture of annuals and perennials in interesting colour combinations.  The gardens contain a variety of Japanese maples. 

Travelling east, the members headed to the Royal Botanical Gardens in Burlington, ON which are the largest botanical gardens in Canada. These gardens consist of formal and informal gardens, lilac displays, roses, hiking trails, interesting combinations of annuals and perennials planted together. Many pieces of “art in the garden” add interest to the gardens. 

The Thousand Island Rideau Canal Garden Tour is a self-directed garden tour of public and private gardens from mid-May to September. To check dates for the tour, refer to their website… .

Montreal Botanical Garden, located in downtown Montreal contains 200 thematic gardens, 10 greenhouses and more than 22,000 species of plants.  It has one of the largest bonsai displays outside of China. This display is moved into the greenhouse for the winter months. 

Jardin Daniel A. Seguin in Saint-Hyacinthe is just south of Montreal. It is a small garden (11 acres) that is recognized for its large collection of annual flowers. Trial gardens for new annuals are located here. As these are teaching gardens, all the plants are well labelled in the many thematic gardens. Hosta gardens are being developed.

Bleu Lavande is a lavender garden located in the Eastern Townships, south of Montreal. 

Jardin Botanique Roger-Van den Hende is a located on the outskirts of Quebec City. The gardens include an annual trail garden and stunning clematis displays. More than 4000 species of plants are arranged by botanical name. 

The Jardins de Metis/Redford Gardens, located in the Gaspe Bay area of Quebec are one of the most northern gardens in North America. Some 3000 species and varieties of plants are located in the fifteen gardens. Of particular interest is the famous Himalayan blue poppy that grows here. Lupins grow throughout the gardens. 

And finally, the most eastern garden on our tour-Annapolis Royal Historical Gardens located in Nova Scotia. These gardens contain formal Victorian gardens and a rose garden with thousands of colourful blossoms. 

Penny ended her travel presentation with a glimpse of her garden and as she said in conclusion, “wherever you go, there is no place like home!”

MARCH 5 MEETING @ 7 pm Tweed Public Library

Quinte Conservation Staff will outline the responsibilities involved in caring for shoreline property. Helpful tips in maintaining healthy shorelines and river/lake beds will be covered.

Christmas Potluck
