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 […]

Redbuds With Very Few Messy Seed Pods
A few years back my church pastor complained about the ugly load of seed pods covering the redbud branches (Cercis canadensis) on the property in the fall. My suggestion to avoid messy seed pods is to plant seedless redbud cultivars. A number of native redbud (C. canadensis) cultivars produce few to no seed pods. Let’s start with the cultivars ‘Ace of Hearts’ and sister seedling ‘Little […]
Key Points Whether To Grow Peaches
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 […]
Tree and Berry Fruit Pollination Chart
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 […]
‘Little King’ Birch For Small Gardens
Little King, aka Fox Valley™, (Betula nigra ‘Little King’) is a 10-12 foot tall shrubby river birch, which fits into small landscapes. Simple minimal pruning can shape it into a lovely small tree. Little King possesses the desirable traits of large river birches, including an oft-white exfoliating bark. River birch exhibits good heat tolerance in the Southeastern U.S. (USDA zones 4-8) and has […]
Foster Holly Has It All
Foster holly (Ilex x attenuata) is an old holly favorite which has not lost its sizzle. While many new holly cultivars have entered the landscape scene, do not assume that Foster holly is now passé. It is utilized in a number of landscape options in the Southern Appalachian region (USDA zones 6 and 7), including in containers in zones […]
Trifoliate Orange –The Barbed Wire of the Plant World
Trifoliate orange (Poncirus trifoliata) is a hardy citrus native to China. T-orange is hardy to -15° F. This strong growing large shrub or small tree can reach 15 to 20 feet in height. Its foliage is deciduous and compound, compared to citrus trees with single simple evergreen leaves. T-orange prefers full day or partial (minimum of 6 hours) […]
Key Points About Growing Peaches
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. Peaches (Prunus persica) tend to flower in early spring, when the threat of spring frost is high across the region. In many years spring frost […]
Disease Free Apple Varieties
Over the past 30 years, the goal has been to develop good eating and storing apples which are not susceptible to four major diseases. The first 3 cultivars released were ‘Prima’, ‘Priscilla’, and ‘Sir Prize’, but they lacked great flavor and storage quality. Apples are susceptible to four serious diseases: apple scab, cedar-apple rust, fireblight, and powdery mildew. Scab, rust and mildew […]
European vs Asian Pears
Growing pears in the Southeastern U.S. is both challenging and rewarding. Both the European (Pyrus communis) and Asian (P. pyrifera) pears are susceptible to fireblight (Erwinia amylovora), a bacterial disease with no satisfactory cure. Two popular European pear varieties, ‘Bartlett’ and ‘Bosc’, are highly susceptible to fireblight. Varieties found to be fire blight resistant are: ‘Warren’, […]
