Fall slowdown in the garden brings many of us back indoors to prepare for the winter holidays ahead. A number of serious canker diseases attack evergreens in the fall and winter if soil moisture is not plentiful. These diseases include botryosphaeria, cytospora, phomopsis, and seiridium cankers. Each organism is capable of causing branch dieback or […]

Alaska Cedar Is Awesome Weeping Evergreen
Over the past decade, gardeners have been planting different evergreen trees in their Southern Appalachian landscapes (USDA zones 6 and 7). One of the newbies is Alaska cedar (Chamaecyparis nootkatensis), a wonderful medium-sized evergreen tree from the west coast of North America. Alaska cedar matures into a graceful pyramidal tree form. Long pendulous flattened sprays of bluish green needles drape from […]
‘Little Lemon’ Goldenrod Acts Like Late Summer Bedding Plant
Across the Southern Appalachian region (USDA zones 6 and 7), the native goldenrods (Solidago spp.) are easy to spot, growing 6-8 feet tall in ditch banks along roadsides and in the poorest of soils. Over the past quarter century short, more compact cultivars have arrived local garden centers. ‘Little Lemon’ grows only 12-15 inches tall with a 18-24 inch spread. This diminutive […]
October Starts Out With Fall Sunflowers
I thank the person who gave me a native swamp sunflower (Helianthus angustifolia). This long-lived perennial appears to have its own internal clock for blooming around the first day of October. Its long narrow rough-textured leaves average 6 inches in length. The 2-3 inch wide flowers appear first on top of the tall 6 to 7 foot plants, and […]
Steps in Re-Blooming Last Year’s Poinsettia
Part IV. In mid-September bring plant indoors as outdoor temps start to drop below 50°F to initiate poinsettia flowering. Poinsettia is a “photoperiodic” plant, which means that floral buds and colorful bracts are initiated under short daylengths. A poinsettia requires 6 weeks of 10 hours or less of light per day. You must be determined to stay with […]
Re-Bloomers Need Your Help
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 […]
‘Chocolate’ White Snakeroot Is A Better Choice
White Snakeroot (Eupatorium rugosum) is native to moist woodland areas in most eastern and midwestern states (U.S.). It grows in average, moist, well-drained soil in full sun to light shade. It is a long-lived and an aggressive perennial. ‘Chocolate’ (E. rugosum ‘Chocolate’) earns its namesake for its chocolaty or burgundy tinted foliage. ‘Chocolate’ white […]
‘Autumn Bride’ Started A Heuchera Evolution
Autumn Bride heuchera (Heuchera villosa ‘Autumn Bride’) is blooming now. This native ground cover, aka “hairy alumroot”, displays wide lime-green foliage which is not as colorful as many new H. villosa hybrids introduced in recent years. However, the white flowers on Autumn Bride are showier and more numerous. Heucheras prefer a moist, well-drained, compost-rich soil. Plants are heat and humidity […]
Gaillardia Survival Depends On Winter Soil Drainage
In recent years several hybrid cultivars of blanket flowers (Gaillardia x grandflora) have been introduced. Some are annuals and others perennials. This North American prairie native is hardy in USDA zone 5 hardy. Gaillardias should thrive in the Southern Appalachian region (USDA zones 6 and 7), but they don’t! Soggy winter clay soil is their […]
Sunpatiens Worth The Hype
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 […]
