Planting before the May long weekend? It depends what you want to grow, and how

As sure as spring frost turns to morning dew, gardeners are once again weighing the old maxim that you shouldn't plant before the May long weekend if you want to reap a healthy harvest.
Should you wait for June's first moon? Or does a changing climate mean an earlier final frost?
More than a dozen early spring shoppers were browsing the hollyhocks, roses and compost at the east-end location of Ritchie Feed and Seed when CBC News visited on a recent weekday morning to ask about their long weekend plans.
"That has changed. It's now the middle of May," said Sheila Lang, who was looking for climbing roses. "I guess it's global warming or whatever."
Stephanie Dragan was looking for Canadian-bred roses, all the better to take advantage of the sunny weather.
"Just because the weather seems to be warming up and so I find we can get a little bit more of a head start on the season," she said. "Things like cold weather vegetables, roses — I like to get planted out a little bit early."
Benoît Côté prefers observable measurement over groundhogs, almanacs or old sayings.
"You subscribe to what the weather is and what good old Environment Canada and other people are telling you," he advised. "You just go with it."
On top of the warmer weather, Victoria Day falls relatively early this year on May 19.
The garden centre's general manager warned you never know when a late frost will strike.
"That wisdom is mainly for annuals and veggies and stuff that are a little less frost-hardy. Usually in May, as long as the soil is warmed up enough, perennials, trees, shrubs — they can go in earlier," Michael Ritchie said.
Protect your 'babies'
At the Growing Together Community Farm near Shirley's Bay in Ottawa's west end, volunteers start their first shifts in the second week of May, and there's a greenhouse prepped for a seedling sale on the weekend of May 24.
Maureen Russell, a self-described "crazy tomato lady," is organizing this year's sale and understands the temptation people feel when they bring home a fresh bounty.
"They're so eager to put them out in the garden, and that's when you're going to get failure," she said.
Russell uses improvised cloches made by cutting the bottoms off plastic bottles to get her tomato plants going. She has also draped sheets and towels over plants to shield them from a late May frost.
"I'm an anxious gardener," she said. "You can take chances with your seeds, but you also need to protect them because they're babies!"

Plant and harvest all year
Over in the Aylmer sector of Gatineau, Hélène Hébert is already harvesting spinach, onions and other hardy crops under the protection of a low fabric tunnel.
"Most gardeners in Canada are just begging for the last frost day to happen, and I don't care about that! I really don't. I just plant whatever is adapted for the season I'm in," she said.
Hébert is a gardening coach with online courses on year-round gardening.
She said climate change has made summertime gardens more vulnerable to hazards such as hail in the spring. She said without protection for heat-loving plants like tomatoes and peppers, gardeners may want to wait until the second weekend of June to plant outside.
Meanwhile, Hébert said her shoulder seasons are benefiting from warmer winters. Spinach she planted in October is ready for harvest, and she added spring plants in March.
"Where I planted my spring garden used to be my winter garden…. The soil in there thawed while there was still snow around, so I was able to start planting my spring garden early," she said.
"It gives you so much more freedom. It shatters the limitations we think we're bound to [in] gardening."

How does a rockslide happen? 'The mountain that moves' was Canada's deadliest

Article content A large rockslide in Banff National Park left up to 15 hikers injured Thursday, leading to one potential death and raising a series of questions about how and why the disaster occurred. Article content With officials still working on rescue and treatment of survivors, it will be some time until an investigation concludes why the rockslide happened. But a look at published research and archive news articles on rockslides provides some general information about the dangerous occurrences. Article content Article content Article content Article content A rockslide happens when a large chunk of rock detaches itself from the mountain where it sits and begins sliding down the slope. Why does this occur? Well, natural erosion or seismic activity can cause a rockslide, as can heavy rainfalls. Human activity such as excavation, construction or mining can also lead to a rockslide. Article content As one chunk of rock begins its downward slide, it can quickly gain momentum and trigger massive amounts of other rock to also begin sliding, leading to devastating effects. Article content notes a landslide or rockslide can occur 'when gravitational and other types of shear stresses within a slope exceed the shear strength (resistance to shearing) of the materials that form the slope.' Article content What's the difference between a landslide and a rockslide? Article content A landslide occurs when sediment or loose dirt disengages from a hill or mountain and begins moving downwards. A rockslide, however, means solid rocks are also being swept down a slope during a similar type of event. Rockslides are also incredibly fast-moving, as they tend to move down a flat surface of a mountain. Article content Article content The Canadian Encyclopedia notes a rockslide can move up to 100 km/hr. Article content The most horrific rockslide in Canadian history occurred in 1903 when a huge slab of Turtle Mountain crashed down onto the town of Frank and Crowsnest Pass (about 250 kilometres southwest of Calgary). At least 72 known residents were killed in the natural disaster, as were an undetermined number of others visiting or passing through the area. Some historians thus put the death toll closer to 90. Article content An estimated 80 to 110 million tonnes of rock were involved in the deadly event that came to be known as Frank Slide. The rockslide only lasted about a minute and a half. Article content Newspaper clippings and archive stories from the rockslide describe the horrific results that led to the deaths of men, women and children. As those clippings note, information about the state of some of the victims was disturbing, but shed light on how powerful the rockslide was: 'The leg and hip of a man was found lying fifty yards from the Imperial Hotel.'

Wet weather expected to help fight Badger wildfire, says N.L. fire officer

A wildfire is still threatening the community of Badger but wet weather is expected to help crews fight the fire, says Newfoundland and Labrador's fire officer. The forest fire started on Tuesday, ignited by a lightning strike near the community. On Wednesday, the province ordered residents of the town to evacuate and head to the nearby community of Grand Falls-Windsor. The provincial government also brought in a province-wide fire ban. Forestry protection supervisor Jeff Motty anticipates Thursday will be a "bust day" fighting the wildfire that's threatening Badger. "If everything holds through, the [fire weather index] should decrease down to a level of moderate," he told CBC News on Wednesday evening, "which will be good for our crews to be able to get in and just start working that fire and trying to put out any hotspots and anything in between that they can get out." He said the fire was 600 metres from the town, but they have downgraded it from a Rank 5 fire to Rank 3. He expects firefighting efforts to pick up as well — there are 35 personnel on site and Motty said they've asked for more resources. "We'll get waterbombers back out on site to work the northwest flank. A helicopter will be bucketing too," said Motty. As of Thursday morning the provincial fire hazard map lists the central area of Newfoundland as having a very high risk of fire. Wet weather 'will help' Meteorologist Angelie Menard said Badger had 2.5 millimetres of rain overnight and she's forecasting more for the area, which is good news for firefighting. "So that will help, definitely, to lessen the fire. And then really we're looking at some more rain overnight tonight, with some two to four millimetres. It could even go up to five. So that will also help," she told CBC Radio's The St. John's Morning Show. But Menard said winds are expected to increase on Friday afternoon, with gusts of 50 kilometre per hour.

In the news today: Canadians facing extreme weather, major projects bill on track

Here is a roundup of stories from The Canadian Press designed to bring you up to speed… Extreme weather affected 1 in 4 people: poll Almost one in four Canadians were directly affected by extreme weather events over the past year, a new poll suggests. The Leger poll — released as Canada copes with its second-worst wildfire season on record — says 23 per cent of Canadians who responded said they were personally affected by extreme weather events like heat waves, floods, fires and tornadoes over the last 12 months. Among those who said they had felt the impacts of extreme weather, almost two-thirds reported being forced to stay indoors because of air quality concerns, while 39 per cent reported suffering emotional stress. Twenty-seven per cent of those who reported experiencing extreme weather said they had to postpone travel plans, while one-fifth said they suffered property damage. CO2 budget for 1.5 C could be exhausted in 3 years The world is on pace to emit enough greenhouse gas emissions over the next three years to blow by an international target to limit global warming to 1.5 C, according to a new study co-authored by a Canadian researcher who says the finding underlines the need for urgent transformational change. The study by more than 60 scientists says the 1.5-degree carbon budget – how much CO2 can be released while staying below that limit – sits at about 130 billion tonnes as of the start of 2025. At current levels, that budget would be exhausted in a little more than three years, the report said. Within the next decade, the budgets for 1.6 and 1.7 degree warming thresholds are at risk too, the report found. Concordia University professor Damon Matthews said 'every increment matters' in the effort to avoid increasingly severe climate impacts, from thawing permafrost to raging wildfires. Major projects bill on track to soon clear House Running roughshod over the environment. Spawning the next Idle No More movement. Picking economic winners and losers. Prime Minister Mark Carney's Building Canada Act is anything if not a magnet for criticism. The Liberal government's controversial legislation that would let cabinet quickly grant federal approvals for big industrial projects like mines, ports and pipelines sailed through committee in the early hours of Thursday. A House of Commons panel sat from Wednesday afternoon to after midnight reviewing Bill C-5 in a hurried study, as the Liberal government seeks to pass it through the chamber by week's end. Disabilities groups ask Liberals to amend tax bill Advocacy groups are asking the federal Liberal government to adjust its proposed tax bill to ensure people with disabilities don't end up paying more to the Canada Revenue Agency. Inclusion Canada says it favours Ottawa lowering the lowest marginal tax rate from 15 to 14 per cent, as proposed in the bill that passed first reading earlier this month. However, the group says the unintended result of the change is that tax credits for people with disabilities will decrease in many cases. That's because the credit — used to reduce taxes payable — is generated by a formula that is tied to the marginal tax rate, and by dropping that rate to 14 per cent, the credit shrinks. Affordability challenges plaguing renters: report A new report suggests Canadian renters continue to face affordability challenges even as asking rent prices have fallen this year, while those considering the leap to home ownership are taking a wait-and-see approach. Royal LePage's 2025 Canadian renters report, which includes results from a survey conducted by Burson, found 37 per cent of renters in Canada spend between 31 and 50 per cent of their net income on monthly rent costs. The survey of more than 1,800 renters in early June indicated that 15 per cent of respondents were spending more than half of their income on rent, while 37 per cent were spending 30 per cent or less. Rents have eased for eight consecutive months, but remain well above historical norms, according to the report. Families fear memories of Air India bombing fading Rob Alexander's father wasn't supposed to be on Air India Flight 182 on June 23, 1985. 'My mother had actually booked him on an Air France flight to go see his mother in India,' recalled Alexander, who was in his teens at the time. 'One of the guys that we knew, he worked for Air India and he wanted to sell my father a ticket very badly to get the commission or something. 'Eventually, he agreed.' Alexander recalled the small argument that ensued between his father and mother, and how she had to cancel his Air France ticket. An Ontario surgeon, Dr. Anchanatt Mathew Alexander boarded the flight in Toronto on the evening of June 22. Early the next morning, about 200 kilometres off the Irish coast, a bomb exploded, sending the Boeing 747 plunging 31,000 feet into the ocean and killing all 329 passengers and crew. The majority were Canadians. — This report by The Canadian Press was first published June 19, 2025
