Pest Alert: Japanese Maple Scale Becoming A Serious Problem

  Japanese maple scale is a new pest in Tennessee and surrounding states. It infests many more plant species than just Japanese maple. The insect’s small size and ability to blend in naturally with tree bark makes it challenging to detect until populations are high and it has infested large landscape and neighborhoods.

Moving Large And Mature Trees

Perhaps tree lovers can’t plant wonderful trees such as shagbark hickory (Carya ovata), American beech (Fagus grandifolia), or white oak (Quercus alba).

Formerly A Tree… Now A Hat Rack

Tree topping continues! The concern about a large tree falling on the house, garage, autos or pedestrians sends out calls to cut the tree back. If the tree in photo does recover (grow), the new branches will be mostly weak suckers. After 2-3 years, the sucker growth will be susceptible to high winds and snow/ice storms […]

Callaway Gardens

Perhaps, azaleas (Rhododendron spp.) offer the broadest color array of any shrub category in the spring garden. Very few public or private gardens display azaleas better than Callaway Gardens in Pine Mountain, GA. In late March, Jane and I enjoyed a 2-day visit at Callaway. We arrived to catch the early blooming azalea sequence and were not disappointed. […]
