This winter's up and down temperatures could take a toll on our plants come springtime.

Neal Denton with UT's agriculture department says this year's cold snaps will put Tennessee back on a more normal winter and spring schedule.

Even though we've had stretches of spring-like temperatures, he's warning homeowners to hold off on landscaping. He says it's still too early to plant and prune.

Denton says the roller coaster temperatures over the past week may have brought plants out of dormancy and put them at a higher risk of damage.

"There is some fear if we get temperatures in the mid-teens tonight and maybe tomorrow night, we could see damage to fruit crops and possibly to some of our other blooming shrubs and plants," said Denton.

There is some good news from the cold temperatures. Denton says they have killed off more than 80 percent of the hemlock adelgid, a tiny insect that has killed millions of hemlock trees in the eastern United States.
