The cold weather you were feeling Tuesday is not uncommon this close to winter's end. Cold snaps like this happen weeks into spring, shortly followed up by the blooming of many different plants and trees. And little cold snaps have names for them, depending on nature's reaction.

You may have heard of a dogwood winter, or a blackberry winter. Those are names of these cold snaps.

It could effect your green-thumb when it comes to gardening.

"People were very aware of weather back in those days," said David Vandergriff with the UT Extension.

The Dogwood Winter. Something that could turn sunshine into snowfall. A cold snap that was followed by blooming dogwood trees. And these cold snaps and their names are generally used in certain parts of the country.

"It's mostly the south Appalachian area. Folks in the Midwest came up with them," said Vandergriff.

Some of these "winter" snaps have folk lore ties to them.

"There was one winter I wasn't aware of. And that was the "Linsey Wool Britches Winter." That one was named after a time where people wore long johns made out of linen and wool," said Vandergriff.

It would signify that it's time to put away the long johns, because the spring is in full swing.

"Certainly this winter we don't want to put our long johns up yet because it keeps hanging on. Even as we move into spring," said Vandergriff.

These snaps affect whether you wear a jacket or not, but they also can decide the fate of a garden possibly started too soon. Sometimes the eagerness to grow that first tomato can be the wrong idea.

"The big day that growers need to be aware of is the last frost day. Which is Mid April for us here in Knoxville."

If you were to plant, and then that final frost hit, Vandergriff said it could kill what you were trying to grow.

A green thumb's warning: better wait until it's time to put up your britches if you want to grow a tomato.
