As an experiment this winter, I am planning to leave some (very) hardy perennials in their big pots on my back deck to see if any survive the winter. I have planted perennials in containers before but never had much success with leaving them in their pots for the winter. I have tried rose bushes and ornamental grasses but apparently they are not hardy enough. The general rule of thumb is they should be at least two zones hardier than your area to survive in pots instead of in the garden.
So, this season I am trying shrub roses, (much hardier than bushes) false spirea, forsythia and lilac bushes, as well as a plum and a maple tree, all of which grow prolifically in my gardens. With the exception of the plum tree that might be a bust, the others are reliably hardy for this area (zone 2). The two mature plums trees in my gardens send up shoots all over the yard so I won’t feel so bad if the one in the pot does not survive. These subjects of my experiment have all been grown from cuttings in my ICU...
Anything else currently in pots that I wish to save must be brought in for the winter. This year that will include a beautiful non-hardy ornamental grass that was extremely expensive, too much so to replace each year…
Many people do not mind rain in winter, as they look forward to spring. The problem is the freeze/thaw cycles that go with the rain can be very destructive to your plants and their containers. I leave many container plants out on my back deck for a few reasons.
I love the look of plants blowing in the wind, especially the ornamental grasses.
Most of the containers are too large (heavy) to move inside
I have lots of them so would need a good chunk of time to move them.
For some reason time always gets away from me in the fall, so the snow arrives before I get around to moving the planters.
Whatever the reason you have left your planters outside for the winter, you can ensure they survive. When it rains a lot (as it has been here for the past few days) or a thaw melts snow on top of the pots, be sure to dump out the excess water before it freezes again. If you cannot dump out the excess water, bail it out. If you do not remove it, the excess water will freeze and your pots will crack. I guarantee this will happen if the containers do not have drainage holes in the bottom. If they do have drainage holes the pots may still crack when excessive rain turns to ice. This happens often here in Ottawa. One day it is raining and almost balmy, the next freezing cold.
Another trick to protect your plants over the winter is to ensure the plants stay snow covered. Snow acts as an insulator, protecting plants from freeze/thaw cycles. I always shovel snow onto my roses growing beside my garage at my front door. This spot is sunny and warmer than the rest of my gardens because the brick wall retains the heat absorbed from the sun. This extra heat means the snow melts faster there, so I have to keep shovelling more on. If you do this, be sure to use snow that does not have salt (from your sidewalk or driveway) in it.
Is it raining where you live? If it is, make sure it does not collect on your planters if freezing temperatures are coming next. Freeze/thaw cycles are brutal on your plants and their containers.

‘Tis the season, my freelance writing season, as Gardens4u is now officially closed for the winter…
Although this past spring and summer were wet and cool, our summer was extended recently with the most marvelous fall weather. Unfortunately, that has come to an end, and reality is settling in.
Now my other interests are able to take over, with a growing list (I am a list person for sure) of the things I hope to accomplish this winter…
reconnect with my freelance writing contacts.
finish the quilt I started for my grandson last winter.
start and finish a quilt for my granddaughter.
make nursery curtains for my new granddaughter due to arrive the end of February.
clean out the few remaining closets I did not get to the past few winters.
reorganize the walk-in closet in our master bedroom.
post more frequently on this and my other blogs: WOW and LOL
spend more time with my grandson and granddaughter (and their parents).
visit with friends I never seem to find the time to visit during the gardening season.
read more books. If anyone has suggestions for a good read, please let me know!
clean my house. Although most people do their spring cleaning in the spring, I do mine in the winter (silly me) so when spring arrives I can get out and enjoy my favourite season.
update my business website, adding pictures from this past season. Be sure to check them out and add your comments!
exercise. Planks are my favourite exercise for maintaining muscle tone. Without gardening to keep me in shape I have to work extra hard in the winter to keep pounds from creeping up on my bathroom scale.
Phew, with that list I should be busy until spring when I can start a new garden season!
Today is a snow day for Gardens4u. I tried hard to get all of my clients’ gardens ready for winter and bulbs planted this week before the snow hit, but will have to wait for better weather before I get them all done. Fortunately, the weather forecast for the next two weeks is promising to be warmer and greener:
I have been hesitant to cut back most plants in their gardens (and mine too) because everything has looked so nice up until yesterday. We have had a beautiful fall season with extended bloom on most perennials and annuals. This snow will take its toll on these perennials and annuals, so they will be ready to be cut back when I get to them next week.
For those of you wondering if it is too late to plant bulbs, you can plant them until the ground freezes. Plant them pointy side up, or if you are not sure which side is up, on their sides. I sprinkle cayenne pepper in the holes with the bulbs and over the soil on top of the holes to deter the squirrels from digging up the bulbs. Another trick is to plant daffodils in the same hole as the tulips. Squirrels hate daffodils. Someone told me to try putting banana peels in the hole with my tulip bulbs to deter squirrels. I haven’t tried that trick yet, but it may be worth a try. Don’t forget to water your newly planted bulbs. If your hose has been disconnected and outside water turned off for the season, get some water from your kitchen sink to sprinkle over the planted bulbs.
The snow is pretty today, but I am glad it is not here to stay. Yet…
The latest Home Depot newsletter for garden club members has some great indoor gardening ideas for these cold winter months…
The first project is a garden dish, or a mini garden, suitable for any room in your home:
for this project you will need the following items:
horticultural charcoal to keep the soil smelling fresh
gravel for drainage
a shallow, low sided, heavy (ceramic is good) dish, with no drainage hole in the bottom. You can use your imagination here to repurpose an old container. Any shape or depth will work with similar instructions, just use thicker layers of charcoal, gravel and soil.
plants, such as coleus, succulents and cacti
moss or sand to cover the soil
decorative items such as shells, pretty stones, pine cones etc
Sprinkle less than an inch of gravel and charcoal over the bottom of container. (thicker if container is deeper than a shallow dish)
Un-pot your plants, and position them as desired, keeping in mind that you are trying to create a miniature landscape. Be sure to use plants with the same light and water requirements in one container. For example, succulents and cacti like bright light, but require very little water. In fact they will rot if watered too frequently.
Surround the root-balls with soil, including a thinner layer over the non-planted gravel areas.
Add a thin layer of moss or sand to ensure soil is covered.
Tuck decorative items into moss or sand.
Moisten your garden with a watering can or in the sink. Let it soak for a few minutes, then carefully tip out the excess water while holding the arrangement in place with your other hand. Repeat this procedure once a week or when the soil feels dry. Make sure your garden never sits in excess water.
Given bright but indirect sunlight, most houseplants will thrive for months or even years in containers. Replace any overgrown or sickly plants as needed.
The next idea is for the transformation of a sunny window into a mini greenhouse that can showcase herbs and houseplants:
You will need the following items:
measuring tape, ruler, electric drill, level, pencil, hand saw
sand paper, wood putty, paint, moulding
1/2 inch thick piece of glass
felt dots or plastic slide
1. Measure the depth and width of the window frame, and subtract half an inch from the width to determine the dimensions of the shelves.
2. Have a glazier cut a 1/2”-thick piece of glass to size for each shelf. For a more finished look, have the edges sanded. Using a level and a ruler for precision, make pencil marks where each shelf support should go, starting from the top of the window frame.
3. Make supports out of moulding by cutting two lengths of moulding for each shelf (the moulding length should equal the depth of the frame). Sand the ends smooth.
4. Drill three evenly spaced holes (just bigger than the head of a wood screw) in each support. Hold a support against the appropriate mark on the window frame, insert the bit of an electric drill through one of the holes, and drill a starter spot into the frame. Repeat for the other holes, and then countersink screws so the heads don’t show. Repeat for remaining supports. Fill holes with wood putty, sand smooth, and paint supports. Once paint dries, attach a felt dot or plastic glide to each support end, and set glass shelves in place.
Filling your home with houseplants, tropicals or locally grown, is a great way to detoxify the air in your home, especially in the winter when windows and doors are shut tight against the cold. Read this previous postto see how this works. To increase your collection of tropical houseplants, take advantage of Home Depot’s current offer:
There are many varieties of tropical houseplants to choose from, including the ever popular orchids. Orchids are easy to care for, providing colorful and long-lasting blooms. They are ideal for the indoor environment of your home and are sure to brighten up the dreary winter months. The biggest challenge when buying orchids is what color to choose as they are all beautiful!
Is winter coming? You would never know it looking at my perennial gardens, especially the roses. Although my calendar says we are approaching mid November and we have been experiencing a bit of cold weather including snow flurries, I am still enjoying plenty of blooms!
My magnolia tree (top left) thinks it is spring; it usually produces these buds first thing in spring before the leaves arrive on the tree. You can see in the picture that the buds are swollen even though the leaves are dead and ready to fall off, a sign of fall and not spring. That magnolia tree actually bloomed three times this summer with all of the temperature fluctuations we experienced.
My many roses, including the shrub, climbing, miniature and bush roses are still producing buds and some look like they are in full bloom.
With the warmer temperatures this past week, especially last Tuesday, (see my previous article Weather ) I had hoped that the rose buds would develop further into gorgeous flowers, but it did not happen.
Although these blooms have brightened up the landscape this past month, it is time to snip off the buds on the roses so their strength will go to the roots for the cold winter!
We won’t be swimming anytime soon in Palmerston Lake. This past Sunday we drove up to our family cottage on Palmerston Lake at Ompah, Ontario to check on the cottage and to see how much snow is left up there…
The lake is still ice and snow-covered; not very inviting. The top of a birch tree on our property had snapped and fallen onto our wood shed; fortunately its fall was broken by two small deciduous trees, so there was no damage to the roof of the shed.
Like my gardening season, cottage season (at least the swimming part of it) may be delayed a bit this year thanks to the long, cold winter we have endured here in eastern Ontario…
The weather forecast had warned us we were about to get our first big snowfall of the season, but when I went to bed last night we hardly had any snow, so I thought the storm had missed the Ottawa area. These are the views I woke up to this morning…
