It is not unusual in Iowa to get one last freeze at the end of the season, but it creates trouble for those green thumbs who planted early.
They have to worry if their flowers, plants, and trees will make it through the night.
“You`ll get some brown edges on the outside of the bud, you`ll lose the bloom for the season, it`s a one and done on most trees, so if it does get down below that and it could take the bud away you`re not going to get a bloom.” Landscape Architect James Noelck explains.
Over at Perennial Gardens in Ankeny, workers expect Iowa’s weather to fluctuate, but whenever a cold front is predicted everyone takes notice.
Noelck says if you have already started planting your flowers for the year, you'll need to cover them up overnight especially if the temperatures drop below 38 degrees, if you can bring them inside or into the garage that's even better.
It's not just flowers that gardeners are worried about; those who have started their vegetable gardens should also be concerned.
At Goode Greenhouses, experts recommend taking precaution with certain crops. “some things are more sensitive things like tomatoes, zucchini, cucumbers, watermelon, that`s very cold sensitive stuff, and even under 45 degrees you could see some damage there,” Colt Stephens explains.
If you haven't planted, the best thing to do is wait. Mother Nature will let you know when it's time to get into the garden.
Experts say you can never be too careful, a good rule is to prepare to cover up most of your garden until May 10th which is on average the first "frost free" date for the Des Moines area.
