The Importance of Winter Watering
The Importance of Winter Watering
While your favorite ski resort may be open for business, snowfall in the mountains as well as the front range is down this year. Reports show that snowpack levels across the state are 47% of normal levels. The southern Colorado region has below-average snowpack for this point in the season. While snowfall has been variable and not consistent even as far back as the 1800’s, there are some trends that we need to consider as gardeners. While not very strong, there is a correlation that has become apparent for lower elevation areas in the state (and could be an indicator for us in future years). If the first snowfall is not until November or later, this correlates to a lesser snowfall total for the area as a whole. This concern aligns with recorded temperatures, indicating that our region is experiencing warmer and drier autumns. This is significant for our landscape plants: trees, shrubs, and perennials. To break it down further, without any supplemental water, our outdoor plants are going longer without moisture after the main growing season and receiving potentially less water even when they do finally get snow. Additional food for thought includes that every foot of snow is roughly one inch of rain.
This corresponds to what we hear and see from our customers who come in the spring to replace plants that have experienced “winter kill.” While the term winter kill is traditionally used to describe icy or extremely cold temperatures that cause plant death, customers are using this term to describe plant death in general over the winter season. The type of death these plants are experiencing is completely preventable. They are dying of dehydration. Dry soils do not insulate roots, and thus plants are more susceptible to freeze damage and the swings of freezing/ thawing that we experience in this region.
When we have mild months, like this past November or December, we need to be winter watering. Winter watering requires you to manually water after irrigation or sprinklers are turned off prior to a freeze. Manually watering sounds labor-intensive in our world of automation, but it is rather simple. Remember, dear reader, gardening is one of the last bastions of manual labor. Enjoy the little labor it takes to have beautiful plants! There is a reason the phrase, “labor of love,” exists after all. I digress. Take a garden hose, if you are up for connecting and disconnecting a hose to a spigot, and let the hose trickle at the base of your plant(s) for a little bit. If you have a mature tree, let it trickle for about an hour or two. Less for smaller or less mature plants. If you don’t want to deal with a hose, take a bucket of water and pour it at the base of the plant for a drink. If you want to water your tree properly, you are shooting for ten gallons of water per inch of the tree trunk’s diameter. Which may be even more work than just pulling out your garden hose, that may or may not be mangled under your lawn mower. Pouring buckets of water repeatedly in the same spot may also cause some erosion, so I prefer the slow trickle method. Do this at least once a month on warm days (above 40- 50 degrees Farenheit).
Some individuals look for quick fixes, so they do not have to manually water. I caution against these methods, even if we carry the implements at Rick’s. Tree donuts, water gators, or water bags that have been designed to slowly water trees should only be used during the growing season, and outside of freezing temperatures. If the tree donut freezes at the crown of the tree, this can also cause death. This invention does not mimic snow. Snow slowly melts without creating a solid barrier. A frozen tree donut of ice prevents the tree’s surface roots from “breathing” or completing their nutrient exchange and absorption. Do not look for a shortcut on winter watering.
While many people believe that plants go to sleep during the winter and therefore do not need any care, this is not the case. This would be like a human being in a coma, but never being given an IV. An IV is to ensure that they are receiving liquids and nutrients until they wake back up! Apply this metaphor to your landscape plants. When we do not have the winter moisture and fail to winterwater our landscape plants, they die a perfectly preventable death. Enjoy the sunshine that is common in a Colorado winter, and pull out that garden hose to give your tree a drink!
