Some grafted and budded shrubs and trees develop a bad habit to sending up shoots (suckering) from its rootsystem. This creates an untidy appearance around the base of shrubs and trees. Far worse, the root suckers may compete for domination over the cultivar graft. They may rob photosynthate, water and nutrients from the grafted plant. Eventually, the grafted portion may die. Gardeners select grafted plants for a number […]

Posted by Hugh on March 16th, 2012
Most artemisias (aka “wormwood”) can not cope with the summer heat and humidity in the mid-South. Their silvery foliage tends to burn out (some say “melt out”) in mid to late summer. ‘Powis Castle’ artemisia is truly the exception. Powis Castle is likely a hybrid (Artemisia arborescens x A. absinthium Powis Castle is a bushy, woody-based perennial […]

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 […]

Posted by Hugh on February 6th, 2012
Peaches grow in other places besides Georgia, USA. A decade long period of mild winters in the Southern Appalachian region (USDA zones 6 and 7) have increased gardener confidence about growing peaches. Peaches (Prunus persica) tend to flower in early spring when the threat of spring frosts is still high. In many years spring frost may kill 80% of […]

Posted by Hugh on February 3rd, 2012
A frequent question of newbie fruit gardeners is what will pollinate what. Do I need many varieties or can all be the same variety? The four common terms are used: Self-pollinated: transfer of pollen occurs within the same variety. Cross-pollinated: transfer of pollen occurs between two varieties. Self-unfruitful: low fruit set unless the blossoms […]

Leyland cypress (x Cupressocyparis leylandii) grows into a 50 foot tall evergreen behemoth. What happens when the plants (in photo) get too close to the small deck(s)? Access to the deck from the stairs will become impossible as the evergreens swallow up the entire back yard. Looking out from the deck and windows from the home won’t be likely […]

Phytophthora disease (Phytophthora spp.) is the fatal cause of root rots, stem cankers and crown rots. Several hundred species of plants are susceptible, including redbuds, dogwoods, rhododendrons, camellias, white pines, firs, yews (Taxus spp.), and fruit trees.

A wonderful, easy indoor gardening project this winter is to start a dish (pot) of paperwhite narcissus (Narcissus tazetta). Paperwhites make a lovely white centerpiece on your dining table. Paperwhite bulbs are outdoor hardy in USDA hardiness zones 8 – 10. Store the bulbs in a warm dry location such as on top of a refrigerator until you’re […]

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 […]
