March Edition

Less watering and more time this Summer

Angela Lassam

It seems every year we are asked to conserve water. Climate change seems to have altered our summers making us reconsider our gardens and grass lawns.

Our lawns are the heaviest user of water so think how you can reduce the footprint in your landscape?

Making walkways with patio stones will save stress on grass when dry and makes for a more interesting view of any garden. 

 Cut down the size of your grass by cutting back edging by 1’ and place edging or an easy task is to put down a mulch edging.

Build a pond with a circulating system. The sound of running water is relaxing and the air will feel cooler for yard comfort. Stock it with fish and they will eat any mosquito eggs laid on the surface.

 Make another flower bed – who doesn’t need more space to grow a new plant? But remember to plant perennials close together to avoid weeding and conserve water. 

Better than that, plant shrubs and ground cover which make a complete soil cover and need less water as it matures.

Mulch round trees where you struggle to get shade-loving grass to grow or plant drought tolerant species or groundcover (needs no mowing).

Building a larger deck or patio will give you more space to spend entertaining instead of cutting grass. 

Set up a graveled play area for children or even for adults to exercise with bocci, ball toss, horseshoes or other games.

If you must have grass and need to reseed take a look at one with RTF  – Rhizomatous Tall Fesque. This grass is newly developed in opposition to Bluegrass,  has a shorter germination time and better appearance.

Clover is a good alternative for bare spot repair as it will stay green even when grasses have gone dormant from drought. It is bug resistant as it is a legume. West Coast Seeds have a microclover on line and other alternatives for grass.

Creeping thyme can be very attractive and considered in the ‘steppable’ group. It grows a shallow rooted mat and has tiny purple flowers and needs no mowing. It grows well in between any stones.

Another plant to try in the ‘steppable’ group is Irish Moss which is bright green in colour and drought tolerant.

There is a dwarf sedum which spreads quickly and grows to approximately 2”, soft to tread on and can be mowed.

Remember any lawn alternative will flower and be pollinator friendly so caution walking on it during flowering time.

All lawns require watering at least once a week. The soil should become moist up to  6” deep. An irrigation system on a timer is the most efficient or a sprinkler set early in the morning allowing water to soak deeply before evaporation.

Alternately save rain water in barrels directly from a downspout. You can substitute it for a rain chain which can also be part of your garden décor. Use this water either early in the day or evening to get the most benefit. 

Lastly do not mow your lawn lower than 2” to give the root system shade and if possible leave fine lawn trimmings on the grass, it will soon wilt.  A sharpened mower will give you a stress free, healthy lawn and well worth the maintenance.

Consider your outdoor space without so much grass. You will practise water conservation, have a more aesthetic garden, spend less time on maintenance and be more cost efficient. Now is the time to take a different approach to your surroundings for the future.

The Tillsonburg Horticultural Society monthly meeting will be on Tuesday April 4^th in the Senior Centre Tillsonburg Community Centre @ 7.30pm. The topic ‘ Human Encounters with Wildlife’ . Salthaven Wildlife Rehabilitation & Education Centre Brian Salt will bring a wildlife ambassador and share his wildlife knowledge. Everyone welcome. Come join us $4 guest or annual membership $20.

Dahlias are one of the easiest and most rewarding flowers to grow. One or more will give you a sense of achievement for the Summer and into Fall with a fantastic array of color.

Dahlias are of the Asteraceae family with Chrysanthemum. Sunflower and Zinnia.  They come in many variations – pompoms, globe, spiky cactus and dinnerplate(growing to 5ft and flower up to15” in size) with a rainbow of colors.European explorers discovered dahlias on the hillsides of Mexico. They are still popular in Europe today. It is said that the tubers are edible, tasting like a cross between a potato and radish.

Nurseries always have the bright colored packages of Dahlias with other Summer bulbs. They are not a bulb but a tuber. The package will show you the type and color.When you open the package, you will find a bunch of tubers like a hand usually packed in peat moss. Now this time of year it will already show you its tip as sprouts will already be forming showing which is the top.

Dig a hole deep enough to allow the growth tip to be just above the soil and wide enough to spread the ‘fingers’. Adding bonemeal is a good idea. Cover and water well. It is that simple. When planting them make sure to space at least 3ft apart if possible.Slugs may eat them if they are grown too close together. Japanese beetles will burrow into the flower head   and the best way to stop this is a stroll through your garden with a bucket of soapy water and pick them off the flower. Planting a group will give you a continuousdisplay until frost arrives.

Applying fertiliser with a low nitrogen level weekly will produce the best flowers.They are one of the easiest flowers for first time gardeners as they will be almost pest free. The leaves may get very small spider webs which is a sign of spider mites.A spray of 1 gallon of water, 1 tbsp baking soda and ½ tsp Dawn dishsoapshould be applied. This is good for powdery mildew and aphids on all plants.

As soon as the first flower has wilted deadhead it ‘cut it off’ as close to the next branchof the main stem. This will allow many more flowers to form. It can also be done when the first bud appears. This will give it a chance to branch from the base of the leaves on the main stem giving you a plant that looks like a bush.

As soon as frost arrives dig up the tuber and cut off the stem. Allow it to dry off, shake clean and place it in a paper bag with peat. Remember to write the color and type on the bag. Store it in a cool place and check periodically for mold. This is all you will need to do to plant again year after year. So give any dahlia space in your garden even plant one in a large pot with a few small annuals. Sit back and enjoy!

ITS STILL JUST DIRT APRIL 2022 by Angela Lassam

Everyone remembers the trees being stripped of their foliage and not being able to sit under a big Maple tree for shade, even finding it hard to go for a walk in a woodlot without being bombarded by small brown beads – yes it was the Gypsy Moth caterpillar munching away in the tree canopy. If left uncontrolled our trees and gardens will suffer dramatically.

The Gypsy moth or its new name ‘spongy moth’ was renamed because of its slur towards the Romani population as it is considered a pest. It was reintroduced to Eastern Canada arriving in soviet freighter.

After the winter when the leaves start to open on a tree the eggs will hatch and become larvae (caterpillar). The newly hatched larvae spin a fine silk thread and it is blown in the wind to infect other trees. They grow very quickly consuming up to one square metre of leaves in a short time and it is during this time we notice the devastation they create. The caterpillar is very easy to see when fully grown. It is dark brown and hairy with a row of red and blue dots. After pupation the male moth, brown in colour will fly between trees seeking the female. Its lifespan is only one week. The female moth which is a cream colour is flightless. She is very easy to see on tree trunks. She lays eggs that look like creamy sacs. There can be as many as 1000 eggs in a sac and many sacs can be seen on the trunks and limbs where they overwinter.  The cycle of the gypsy moth starts again.

There are some ways to reduce their population. When the leaves are just forming in May a bio-pesticide BTK can be sprayed on the tree as far up as you can reach. Read the instructions carefully before applying. Wear protection as suggested but it is harmless to humans as the solution has bacteria specifically for insects.

The alternative is to wrap the trunk with a band of burlap 18” wide. Tie it with string round the middle and fold downwards to create a pocket for the caterpillars to crawl into. Remove them daily into a bucket of bleach and dish soap and dispose of later. Use gloves and be careful as the hairs on the caterpillar can cause severe irritation.

Another way is to carefully scrape the egg sacs off the tree and dispose the same way as caterpillars.

There is some happy news that within three years of a severe infestation it is reported they succumb to viral and fungal pathogens.

Another problem in our garden is a tree that can be found in woodlots and many established gardens. It is the Black Walnut tree. If you have moved into a new home you may have one in your garden. They grow quickly and give a large shade canopy but it nothing will grow under it. A chemical called juglone can be found in all parts of the tree. The fruit (nuts), leaves and roots all leach juglone into the soil. Leaves and nuts should not go into the compost and the roots of this large tree make an area of 50’ from the trunk tainted with juglone. Plants will be stunted, have yellow leaves and poor flowers. There are plants that are not susceptible to its toxicity. Ones well known to gardeners are hostas, hollyhocks, astilbes, purple coneflowers, chrysanthemums, snowdrops and grape hyacinths. Also forsythia, mock orange and yucca will do well. Once any flower has been planted under a black walnut tree it cannot be transplanted in another area as the juglone can live on in it and taint the area around it.

Perennials are the backbone of any garden and show continuous color throughout the year. They are so versatile giving structure and texture to create a pleasing picture at any time. You buy them only once for years of pleasure and they need little care and attention.

A perennial is a flower that returns in the garden every year when the soil warms up putting up small buds or tips to remind us where they are.

Most perennials are good to stay in the garden. They go dormant and wait for Spring but there are some that have been introduced from warmer climates and these need to be dug up every Fall and stored to be replanted in the following year. Learning of the types of perennials will help.

Whether you are starting a new bed of flowers or adding to your landscape you will need to read the tags on your choice. The height, width, how much sun and drought tolerance are important. The time of blooming will allow you to have flowers blooming continually to give a glorious show all Summer. Your garden needs to be layered and will be beautiful if the selection of perennial flowers are carefully chosen. A little sketching of a new bed before you buy will give greater satisfaction. Remember they will grow much larger as years go by.

It is less expensive to buy bare root perennials from catalogues, stores or nurseries but their appearance can be disturbing unless you are aware of their characteristics. New gardeners may be surprised at their appearance so let me explain the differences.

Most plants are bare root which is a main centre with hairy roots. These can be planted directly in your garden after risk of frost and watered well to settle the roots. A name marker and a support is a good idea. They will soon produce leaves as the weather gets warmer. Remember the tallest towards the back of a bed. Names of a few are coneflower, poppy, shasta daisy and taller phlox. All of these can be divided in later years to replant elsewhere in your garden or share with fellow gardeners.

Other roots with eyes are called rhizomes, once planted can be left in the soil from there on. The eyes are small tips. The more eyes on the root you purchase the more flowers you can get. Astilbe, Hosta and Peony are in this group and do not require planting too deep, just cover the eyes with soft soil. Peonies will need a cage or other support as flower heads get heavy.

There are other rhizomes that have an underground stem, planted almost on top of the soil. The stem will send out roots, more stem with leaves, and flowers along its length. All irises are like this and will grow into a large clump in a few years. If your iris ’are not producing flowers it may be from the root borer so dig them up and cut away holey parts and replant. The following year – more flowers!

Tubers are bulbous roots with small growing tips which will be the flower. Some of these will need to be lifted in the Fall and stored in peat moss, then replanted the following Spring. They do not like to freeze. Their appearance in packages are tubular with thick skins. For the first year these can be potted and started indoors to give you early flowers. They need to be dug up in the Fall and stored in a dry place preferably in peat moss. Replant the following year for more joy. Dahlias are the best ones which come in all sizes and maturity dates for a continual summer color. Be sure to check the package details.

Of course bulbs should be considered perennial flowers as they will come back year after year. Spring bulbs once planted in the Fall return every year and will naturally multiply and are the first splash of color in the garden-  daffodils, tulips and crocus to name a few. Summer bulbs are the Allium and lilies which are very showy planted in groups.

The choices are endless and all gardeners have some of them in their garden because they are the basis of all landscaping both formal and heavily planted beds. They are rewarding every year and need only deadheading and watering with a fertiliser mix to give a wonderful show.

The Tillsonburg Horticultural Society has returned to its monthly meetings in the Senior Centre Auditorium, Tillsonburg Complex.

It’s Still Just Dirt, The Tillsonburg Norfolk News – May 2021
by Angela Lassam 

There are many good reasons for us to give dandelions some space.

Dandelions have been given a bad name by the gardeners who wish for a perfect lawn. It is not the invasive weed most people think it is. 

It is a perennial herb introduced to the U.S. and Canada by the pilgrims who brought dandelions with them to use as a medicine and food crop. The yellow flowers are the first color we see after the winter and you will see fields of permanent pasture and roadsides covered with the flowers. They pop up in lawns every year even if you try to eradicate them. Many people consider them to be weeds.

The flowers are the first pollen and nectar for bees and other insects and the leaves and seeds feed birds, chipmunks and other wildlife. Later the fluffy heads will be used by hummingbirds to line their tiny nests.

For the gardener the roots will go deep (it is said they will grow 10’ to 15’ deep) and will open the hardest, poorest soil. When the plants are cut and composted they can add nutrients to the soil as they are rich in calcium, iron and potassium.

All parts of a dandelion are edible. It has a bitter, peppery taste. The root can be dried and used as a coffee substitute as it is in the Chicory family, or roasted and used as you would use turnip. The leaves can be added to a salad, pizza or made into pesto. They can be made into chips similar to kale. Remember if using leaves pick from where there has never been any pesticides or herbicides applied. The flowers can be added to a salad or make a refreshing tea. You can use the flowers to turn your hand to making a good wine.

Dandelions have been used medicinally for centuries. They are rich in vitamin A, C and K. They can be used to detoxify the body and support healthy liver and kidney function. They are reputed to be an appetite stimulant, diuretic, anti-inflammatory and able to balance blood sugar also lower cholesterol. The sap/milk in the stem is latex. It is said to cure warts and can be used to heal scrapes and cuts.

For spinners and weavers who use natural dyes the dandelion has many colour variations. The root with alum create magenta, added to tin and vinegar gives a purple, and the flowers produce a vivid yellow. 

Maybe with this knowledge you may give the ‘weed’ a second thought. It gives us our first glow of outdoor colour in the spring. Every part of a dandelion has been proven good for our gardens and our health.

I used dandelions as my subject as it is yellow. It is the colour of hope and Communities in Bloom and all gardeners are encouraged to plant ALL yellow. It is our hope to end the pandemic and get back to a new normalcy.

The Tillsonburg Horticultural Society has had a positive response to a modified Junior Gardeners Program. For any information contact Pat Zeyen –  email patzeyen@gmail.com.

There will be a Zoom meeting for members on June 1st@ 7.30 p.m. featuring Denis Flanagan. The topic will be Gardening Trends, New Varieties and Fusion Gardening. Watch for email.

All updates to Society news will be posted on the website www.tillsonburghorticultural.ca and Facebook Tillsonburghorticultural.

It’s Still Just Dirt, The Tillsonburg Norfolk News – April 2021

We are all enjoying the beautiful days and doing the cleanup in our gardens. The sunshine gives us the energy to get active but temperatures will drop and aggressive gardeners may be sorry for their haste.

It is acceptable to remove all leaves left as a false mulch around perennials to allow them to shoot. Remove all dead pieces surrounding the bottom of perennials and pull any dead leaves from the centre to prevent mold /fungus from killing them. It is also a time to relocate them to a more suitable spot if they are not performing as you expected or divide them to control their size and shape. 

Pruning is a good task as branches are easier to take out without leaves and removing crossed branches. Shrubs need bottom cleaning to deter attacks from insects and keep their shape. You may see small new growth beside a shrub and this can be carefully removed to plant elsewhere to make a new one or give away. 

Hoeing will loosen the soil around plants to help them start regrowing and you can remove any early weeds.

Lawns need care and now is the time. Pick up any trash and fallen branches and assess bare patches for later repair. Then roll to flatten out holes and trails made by rodents over the winter. As the grass grows you will need to fertilize.

It is not the time to plant annuals as they need a soil temperature of 20 degrees C. and cannot take air temperatures below 10 degrees C. Plants will be stunted if placed in cold soil. Soil in raised beds is generally warmer and can be planted sooner. There are some vegetables which can be sown or planted preferring the cooler days to start. Potatoes, peas, carrots, swiss chard and radish are in this group.

Planning where to use annuals is a rainy day thought and there is an initiative this year in the gardening world to grow “all that is yellow”. It is called “Hope is Growing” and Communities in Bloom is promoting yellow as it is the color of hope. The country could be aglow with yellow if everyone plants predominantly yellow. Public gardens, planters, front yards and anywhere flowers can be seen are encouraged to be yellow. For those people who are interested in participating in the “yellow” summer go to https://www.hopeisgrowing.ca .      

There is a David Austen rose launched especially for this year which is yellow. It is called ‘Nye Bevan’  to honour Aneurin Bevan who founded the National Health Service in the UK after World War II  and in recognition of the healthcare workers around the world. Sadly it is unavailable in Canada but there are many yellow roses you could purchase.

Tillsonburg Horticultural Society has decided to renew the Junior Gardens Program this year. There will be a limit of 100 gardeners of all ages. The theme this year is “Plant a HOPE Garden” to partner with Communities In Bloom, ‘yellow for hope’ using yellow 4 o’clocks, sunflowers and yellow beans as part of the planting package. More information to follow as the program has been redesigned for the safety of our gardeners and volunteers. This will be co-ordinated by Pat Zeyen  contact patzeyen@gmail.com.

Tillsonburg Horticultural Society opened a Zoom meeting on April 6th which was all about birds. This was to connect members and an email follow-up was sent with very interesting media sites for all to enjoy. No new updates for the future due to Covid restrictions.
