Why your perennials don't survive in winter: Gardening mistakes

Perennials are plants that live for multiple years, typically coming back each spring after a period of dormancy during the winter. 

However, there are several reasons why perennials might not survive the winter.

Let's find out more.

Hardiness Zone

Perennials are categorized based on their hardiness zones, which indicate the minimum temperatures a plant can tolerate. 

If you're growing a perennial that is not well-suited for your climate's hardiness zone, it may struggle or fail to survive the winter's cold temperatures.

Extreme Cold

Extremely low temperatures, especially if they drop below a perennial's cold tolerance, can damage plant cells and tissues, leading to winterkill. 

Frost heaving, where the freeze-thaw cycle causes plants to be pushed out of the soil, can also expose roots to the cold and drying winds.

Lack of Winter Preparation

Some perennials require specific care before winter sets in. 

Failure to properly prepare them by trimming, mulching, or protecting them from harsh winds can leave them vulnerable to winter damage.

Moisture Stress

Drought stress during the fall months can weaken perennials, making them more susceptible to winter damage. 

Inadequate moisture can lead to desiccation and freeze injury.

Pests and Diseases

If perennials are already weakened by pests or diseases before winter, they may have reduced defenses against cold temperatures and may not survive.

Soil Conditions

Poor soil drainage can lead to waterlogged roots during winter, causing root rot and other issues that can kill perennials.
