As temperatures dip in autumn and the threat of frost hovers, most plants take the opportunity to rest from the hard work they’ve put into creating blossoms and fruit. “All plants need a breather after seed is produced and before active growth,” says Michelle Reid, the horticulture foreperson for Toronto Parks, Recreation & Forestry. “In northern climates like ours, this dormant period coincides with winter.” But while hardy shrubs and perennials can withstand the cold under their blanket of snow, our shivering fragile specimens need extra protection to survive. From aquatics to herbs to tropicals, learn what you need to do to protect your plants.
