Deer Repellent


Anti Desiccant






Our landscapes are valuable.  Annually, most homeowners put a lot of expense into planting and maintaining their properties only to see them devastated by deer feeding.  We have been very successful in combating the deer epidemic by applying deer repellent sprays at regular intervals.  This scent deterrent keeps them from approaching plants as it is associated with predator activity.




Anti desiccant sprays are useful in reducing "winter burn" in broadleaf evergreen shrubs and evergreen trees planted late in the year.  When plants are dormant, they can't replace moisture that is lost by the foliage due to natural transpiration.  Anti-desiccants are naturally bio-degradable materials that plug up the stomata or cells in the leaf that allow water to escape.
