Jan 31 Notice from Denver Parks & Recreation:
It’s going to be a warm weekend which means it’s the perfect time to water your trees! This winter has been especially dry, so residents are encouraged to water trees on their property when temperatures exceed 40-45 degrees. Without consistent moisture, trees become stressed and will not have enough energy to ward off pests, disease, root death and crown die-back. Use the FLOOD IRRIGATION TECHNIQUE: Leave a hose on low-flow for at least 15-20 minutes, moving it around the base of the tree every few minutes until the entire root area is moist. It’s important to note that tree root systems are wide, so water under the entire canopy. The goal is to water enough so that it can seep at least 12″ deep into the soil to reach the root system. Because the ground is cold, this may take a couple days of watering to accomplish. Let the soil dry out before watering again.
