Renovate Windbreaks to Improve Effectiveness
Over time it isn’t unusual for windbreaks to thin and loose the capability to block strong winds. However, proper renovation efforts can keep any windbreak in top-notch condition.
According to Rich Lodes, District Forester, Lower Platte South NRD, “Some landowners choose to renovate a windbreak because it has become aesthetically unappealing while others are forced to take action in order to keep out strong winds. If this is the case, there are particular signs to look for that indicate a windbreak is in need of renovation.”
During winter, an effective windbreak should prevent snow from blowing through to locations where it can block driveways and houses. However, an ineffective windbreak is evident during other seasons of the year. For example, corn stalks and leaves often are found near buildings and in corners where debris normally isn’t seen. The ability to see previously unseen objects through a stand of trees usually is a good indication that the windbreak needs renovation as well.
There are four methods commonly used for windbreak renovation.
- Cut down the entire stand of trees and start new. Although this method is the easiest way to regain a clean look, it is expensive and provides no protection in the meantime.
- Remove and replace half of the stand. This method allows the introduction of new growth but still provides some protection against wind.
- Add a row or two inside or outside of the existing stand. This method allows the introduction of new growth as well. However, many landowners are reluctant to give up either lawn space or farm ground.
- Establish shade-tolerant species within the stand. This method often seems undesirable because it creates a stand with trees of multiple ages and heights. Even so, it greatly increases the density of the windbreak and prevents more wind from getting through.
Lodes says it is important to remember that renovating a windbreak, regardless of method, can be a difficult task. Wildlife species that exist in the established windbreak make growing new trees and shrubs especially difficult. Even so, cages can be set around trees to prevent rabbits and deer from eating the plant.
