Northern Illinois is again under a freeze warning.
The National Weather Service has issued a freeze warning for much of northern Illinois, including Cook, Lake and McHenry Counties. According to the National Weather Service, temperatures may drop below freezing for a few hours overnight. The freeze warning is in effect from 1 until 8 a.m.
"With the record warm March bringing vegetation growth far ahead of schedule, sensitive vegetation may be damaged or killed by the freezing temperatures," the National Weather Service said in its freeze warning statement.
The Gardening Know How website offers some tips to protect plants during a freeze, including:
- Cover the plants with a sheet or blanket — and even place plastic over the sheets or blankets to retain the warmth.
- Remove the sheets and blankets first thing in the morning to avoid condensation build-up.
- Water the soil to help the soil retain heat.
