Warm days and Cold Nights
Water over the Winter months to protect newly planted trees.
By Chris Leinster - January 21, 2020
Ice is still clinging to storm drains and parking lots but it has been three weeks since it last snowed around town. Daytime temperatures have been reaching into the 50s, while dropping into the mid-20s overnight. This is really tough on trees and shrubs, especially newly planted trees that haven't spread their roots deeply into the surrounding soil.
This pattern looks like it will continue through at least this week. Please get the hoses out and do a little winter watering to get some moisture into the ground.
If the ground is still frozen or snow covered you don’t need to do anything just yet. Just please keep an eye on the ground moisture and water on a warm day as needed. A good soaking should be adequate to get us to the next precipitation event.
If you have a recently planted tree from Happy Trees, your water gauge can show you if moisture is available in the root zone. Otherwise you might dig a little in the vegetable garden or other inconspicuous place to see if there’s moisture in the soil or not. With Colorado’s intense sunshine and Chinook winds it doesn’t take long for the ground to dry out completely.
One last tip…temperatures are still dropping below freezing at night so disconnect your hose from the tap to prevent freeze damage. Drain your hoses so they don’t freeze as well. Winter watering helps protect roots when the ground freezes, so be aware of your plant’s needs and water as necessary.
