Did you know that Colorado’s cold, dry winters can cause significant damage to the roots of trees, shrubs, and other perennials? Once this damage occurs, it can be permanent, affecting the long-term health of the plant. So, how can we protect our plants from winter’s harsh effects? That’s where winter watering becomes essential, providing moisture during dry spells in order to help plants stay resilient until spring.
Caring for Your Plants During the Winter
While trees and shrubs may appear dormant in winter, they are still actively working to survive the cold. In dry, windy conditions—especially when there’s minimal snow cover—roots can easily dry out, which can lead to permanent damage that hinders your plants’ ability to absorb the nutrients they need to thrive. This root damage weakens plants, making it more challenging for them to recover in the spring. Winter watering, if done correctly, helps to protect the roots of your trees, shrubs, and perennial plants from drying out, leading to more healthy and vibrant growth during the growing season.
Tips for How to Winter Water
While winter watering is essential for healthy plants, especially those planted within the last couple of years, it is even more important that this task is completed correctly. Improper winter watering can have adverse effects, though this is easy to avoid by employing the proper technique. Here are some important factors to keep in mind when watering your trees, shrubs, and perennial plants this winter.
Winter Water in the Absence of Consistent Precipitation
Typically, your plants will need winter watering if there has not been consistent precipitation or if the soil around them feels dry to the touch.
Winter Water if There is no Snow on the Ground
If there is no snow on the ground around your plants and daytime temperatures are above 40°F, it is probably a good idea to break out the hose.
Winter Water on Warm Days
Watering your plants on warmer days will ensure that the water will not freeze before the plant is able to soak it up and put it to use.
How Frequently to Winter Water
If there has not been consistent precipitation, watering once or twice per month, as conditions allow, is usually sufficient to help protect plant roots from drying out.
Avoid Watering on Windy Days
Avoid watering on windy days, as dry winter winds will carry off or evaporate much of the water you are attempting to give to your plants.
Water at the Right Time of Day
Watering around midday when temperatures have had a chance to warm up leads to heat being trapped in the soil, which can help keep your plants warmer throughout the night.
Be Careful not to Overwater
Since your plants are dormant, they won’t need as much water as during their active growing season. Stop watering when the soil no longer absorbs the moisture readily, as the pooling of water can lead to root rot or suffocation.
Pay Particular Attention to Newly Planted Plants
Plant material that has been recently planted (planted within the last 1-2 years) should be paid special attention throughout the winter. Their root systems have likely not had a chance to fully establish, making them more susceptible to damage throughout the winter. Receiving consistent and adequate moisture throughout the winter months is paramount for their survival.
Keep Your Gardens & Landscapes Healthy this Winter
Winter watering is an essential step in protecting the health of your trees, shrubs, and perennials during Colorado’s cold, dry season. By giving your plants the right amount of water at the right time, you can prevent root damage and dehydration that could otherwise hinder their growth in the spring. While it may seem counterintuitive, careful winter watering actually helps keep roots insulated, protected, and ready for the upcoming growing season. Following these few simple guidelines ensures your plants get the support they need to survive and thrive through winter.
