SHERMAN, TX -- Today is March 20, and we've already seen a crazy month weather-wise. Some say the plants may be jumping the gun.

The leaves on this corkscrew willow are green. The redbuds are blooming, about one week earlier than normal.

"We were doing a job at Murray State, a memorial garden and they had a saucer magnolia and about 3,000 blooms that morning; when we arrived it was all frozen," says Jonathan Castro with Texoma Landscapes and Gardening.

Between the snow and the rain, plants are trying to adjust just like the rest of us to the changing weather.

"Plants have an ability to adapt,” he says. “Shortly after that, there were another 1,000 blooms that did make it. They're still blooming so it likes it was a little early coming out."

Some scientists say global warming may also play a factor. Studies show birds are shifting their flight patterns. Plants are blooming at different times because of climate change worldwide. This can affect wildlife and your garden at home.

"You always want to err on the side of caution because they say Easter is the demarcation point,” Castro says. “Easter's a week early, so you might want to wait even longer."

Experts urge those with the green thumbs to keep your gardens covered in case of cold weather so all your hard work doesn't go to waste.
