Trees – a vital part of our green infrastructure – may be dormant now, but they are still susceptible to cold and dry conditions. Lack of water through the winter season can damage root systems. The weakened trees may look normal in the spring, but will usually die back later in the summer.
Protect your trees with these winter watering tips:
– Water only when the temperature is above 40 degrees with no snow or ice on the ground.
-Water early in the day, so the water can soak in before the temperature drops at night.
– Use a soaker hose to focus water on the roots and avoid spraying branches or evergreen foilage.
– Water trees one or two times per month until they begin leafing out in the spring.
Water newly planted trees. Recent high temperatures coupled with wind and low humidity make new trees more susceptible to stress.
1. Water trees slowly at the base of plants to give them a deep soak. Avoid frequent short waterings, like the lawn, which provide only shallow moisture.
2. Water in the morning to avoid evaporation and help the tree cope the heat of the sun throughout the day.
3. Soaker hoses or tree bags work well for the slow soak tree watering and a 3″ layer of can provide a new tree a buffer from heat, retain water, and avoid root competition with weeds.
Trees are valuable assets to our community. They help shade from heat, shield from cold, manage stormwater, prevent erosion and fight air, water, and noise pollution. So set them up for success with good watering now.
For your trees, that is. This weeks warmer temperatures provide a good opportunity for a mid-winter watering for landscape trees.Trees that are newly planted or near the south or west sides of a building are most susceptible to winter drought.
Check if the tree needs watering by pushing a screw driver into the soil near the tree. If it only goes in an inch or two, the tree needs water. If the screw driver goes into the ground and returns with a bit of mud, there’s adequate moisture If it comes covered in mud, there’s more than plenty of moisture.
For thirsty trees, provide 2-4 gallons of water on a 40 degree or warmer day. Apply water mid-day to allow time for soaking before possible freezing at night.
