Wintry blast coming our way; here’s how you can best protect your plants


DEFIANCE, Mo. – St. Louis weather strikes again, bringing the cold and possible snow back to our area.

“Again, we are not that cold. But we are cold enough it is going to be a little tricky this time,” said Tony Frisella, Frisella Nursery in Defiance. 

As temperatures fall, the leaves may drop with the mercury.

“It depends where you are at. If you are in the city, it’s going to be a little bit warmer,” Frisella said. “If you are out where we are at, it’s going to be a little bit colder.”  

The concern is a matter of a few degrees. Anything under 28 degrees can be deadly, so protection is key. 

“We want to get this all the way down to the ground. Keep it out as much as you can get to absorb as much ground heat as possible. The idea though is not to use plastic. This is a special cloth for a freeze,” Frisella said. 

And there’s one thing that may seem counterintuitive. Warm days leading up to the freeze are damaging, but the snow may actually help. 

“No, actually, the warmer it is the worse it is. It’s those fast temperatures drops that are even harder on the plants,” Frisella said. “Snow and water is actually a way of keeping them from frosting.”  

To mimic rain and snow, Frisella Nursery will run sprinklers to help ice the plants to protect from a frost. But when it’s below 28 degrees, it’s not that simple. 

“Now when we get down below 28 degrees that’s iffy. So that’s going to be a little bit more of a deal where we watch what we are doing,” he said. “We have to cover more plants we can’t necessarily just ice them this time.”

President Harry Truman said: “It is amazing what you can accomplish if you do not care who gets the credit.” That spirit is alive and well at Fox 2. Our teamwork is on display each and every day.

Our news slogan is: “Coverage You Can Count On.” We quite frankly are too busy to worry about who gets the credit. Our main concern is serving the viewer.

We go where the stories take us. Whether it be Washington, D.C when a Belleville man opened fire during a congressional baseball game practice or to Puerto Rico where local Ameren crews restored power after more than 5 months in the dark.

Coverage You Can Count On means “Waking up your Day” with our top-rated morning show. From 4:00 am-10:00 am we are leading the way with breaking news. But our early morning crew also knows how to have some fun! Our strong commitment to the communities we serve is highlighted with our Friday neighborhood shows.

Our investigative unit consists of three reporters. Elliott Davis focuses on government waste, Chris Hayes is our investigative reporter, and Mike Colombo is our consumer reporter. They work in unison with the news department by sharing resources and ideas.

We continue to cover breaking news aggressively and relied on our seasoned journalists to make a difference with the stories we covered. The shooting of Arnold Police Officer Ryan O’Connor is just one example of that. Jasmine Huda was the only reporter who had exclusive access to the O’Connor family during his amazing rehabilitation in Colorado.

Last, but certainly not least, FOX 2 and KPLR 11 are committed to covering local politics. We host debates among candidates and have the most extensive presidential election coverage. Our commitment to politics isn’t just during an election year. We produce two political shows that air every weekend.
