The Right Rhododendron for the Right Location
Posted by Hugh on March 2nd, 2012
Rhododendrons (Rhododendron catawbiense) were born in the cool of the North Carolina and Tennessee mountains. Hundreds of lovely hybrids have been bred by dedicated plantsmen. Winter hardiness is rarely an issue, but rhododendrons are challenged by summer heat and disease problems in the Southern Appalachian region (USDA hardiness zones 6 and 7). Your most important decision is [...]
Volcano Mulching Harmful
Posted by Hugh on January 1st, 2012
Piling up mulch around trees or shrubs, called “volcano mulching”, is a bad practice and is killing them. Perhaps you’ve seen a neighbor or a professional landscaper doing it, and assumed that it must be alright. It’s not! The deep mulch pile smothers the natural buttress flair of the trunk which breathes and absorbs air for [...]
Key Points About Growing Peaches
Posted by Hugh on December 8th, 2011
People think peaches grow only in Georgia. A decade long period of mild winters in the Southern Appalachian region (USDA zones 6 and 7) have increased gardener confidence in growing peaches.

1 Comment »Natural Evergreen Needle Drop in Autumn
Posted by Hugh on October 25th, 2011
Some needle loss on evergreens in the fall is natural. As night time temperatures cool, needles in the interior of many evergreen trees or shrubs regularly turn brown (or golden yellow) and drop off. Needle loss is most obvious on pines (Pinus spp.) and arborvitae (Thuja spp.) in the Southern Appalachian region (USDA zones 6 and 7). The [...]

Depending on where you garden, Canna lily (Canna spp.) is a tropical-looking, herbaceous annual or perennial. Its colorful foliage and long blooming time leaves a huge visual impact. Canna is not reliably winter hardy in the Southern Appalachian region (USDA hardiness zones 6 and 7). [...]
Ice Storm- Keep Hands Off
Posted by Hugh on December 26th, 2010
An ice storm is both a beautiful and horrific scene in a garden. The potential for major tree/shrub breakage is staggering. If you feel powerless, this is good thing. During the storm, do nothing / “hands off”. Most actions will likely cause more damage than what nature may have intended. After the storm assess the landscape areas which seem most vulnerable, or [...]
