Subsurface Fertilization and Watering

Watering

Many, but not all trees along the Front Range are often starved for water, especially in late Fall through early Spring when irrigation systems are turned off. Summer can also be a difficult time for trees where access to irrigation is limited or non-existent.

Watering your trees during the winter can reduce the effects of environmental stresses such as drought and freeze-thaw cycles. Just run the hose on low under the tree for an hour per month on days when the weather is warm and the ground isn’t frozen.

Drought-resistant trees such as Austrian pine, pinyon pine, Scotch pine and ponderossa pine do not typically need supplemental water any time of year. Overwatering these trees can cause stress and make them more susceptible to diseases such as boring insects and root rot.

Walker Tree Care offers deep-root watering services for clients who can’t or don’t want to water their own trees. We inject water containing a wetting agent a few inches beneath the surface to deliver it directly to the roots where the tree can take it up. The wetting agent allows the water to moisten the soil more readily, and get into the tree more quickly.

Fertilizing

Trees that have been stressed by drought or other environmental factors sometimes need a little boost to restore their vigor. Subsurface fertilizing can often help. Trees that appeared healthy just one or two seasons ago, but are beginning to show signs of dieback on the tips of branches may not be getting the nutrition and water that they need. Walker Tree Care can inject a solution of nutrients, humates, and beneficial fungi and bacteria into the root zone of struggling trees to help bring back their vigor. Of course, not all trees showing such symptoms are suffering from lack of nutrients in their root zones, but we can help you determine if that is the case, too.
