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. 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 […]

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 […]

Posted by Hugh on December 4th, 2011
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’, […]

Elderberry (Sambucus canadensis) is native to eastern North America, commonly found growing in open fields, thickets, fence rows, and along roadsides. Elderberry has pinnate leaves with toothed leaflets. Large flat clusters of small white flowers are evident by early summer, followed by large clusters of round purple-black fruit in late summer and fall. The fruits are […]

Posted by Hugh on November 23rd, 2011
Callery pear (Pyrus calleryana) has been declining in planting popularity. But its scarlet red leaf color is both sensational and reliable every autumn in the Southern Appalachian region (USDA zones 6 and 7). Most people identify the tree by its cultivar name, e.g. ‘Bradford’, Aristocrat®, ‘Cleveland Select’, ‘Redspire’ pear. There are many other cultivars. Callery pears are tough reliable medium sized trees which […]

Finally, Americans are paying closer attention to our wonderful native plants. In the Southern Appalachian region, there are 16 and more species of deciduous azaleas which may be grown here. In addition, there are numerous natural hybrids growing in the mountains. I asked Jay Jackson, owner of Appalchian Native Plants, Inc. in Laurel Bloomery, TN […]

Does your garden need a refresh? Summer’s heat and drought, devastating storms, and disease and pest problems combine to place a pall over your outdoor living space. Perhaps, you desire an entirely new look. Maybe you’re tired of the same old beds of roses, daylilies and other perennials. Maybe your garden saps too much of […]

Posted by Hugh on September 10th, 2011
Re-blooming is an unusual plant trait. Selected cultivars return this time of year for a repeat floral show. In my garden Encore™ azaleas (Rhododendron spp.), re-blooming irises (Iris spp.), and re-blooming daylilies (Hemerocallis spp.) are back for second round of flowering in late summer and early fall. The gardener/landscaper must supply needed soil moisture and nutrition (primarily nitrogen) so that plants don’t struggle […]

Posted by Hugh on August 26th, 2011
Sunpatiens™ live up to all their hype, with a caveat. They are still impatiens, which means they love (and can’t go without) water. In the Southern Appalachian region (USDA zones 6 and 7), Sunpatiens prosper in direct full day sun to part shade, but can’t go without weekly watering. The flower bed should be mulched […]
