(WZZM) - Rhododendrons and many other blooming plants have taken off already this year, due to our warm March weather. Greenthumb Rick Vuyst says we need to keep an eye on those plants because we usually don't get our last frost until around May 15.

Rick recommends pitching a stake in the middle of the plant to support a plastic covering, like a tent. This will help keep the plants warm on the cold nights.
