Need To Deadhead Perennials

Deadheading is the practice of removing spent blossoms to stimulate re-blooming. It also refreshes the plant’s appearance, and lessens the threat of seed dispersal. It redirects the plant’s energy from seed production to root and shoot growth. Deadheading is an extra chore throughout the growing season. When the plant (perennial or annual) has stopped blooming or […]

Better Choices Than Leyland Cypress For Privacy Screen

For homeowners in a rush to establish a tall green privacy screen from the neighbor(s), perhaps a 12-foot tall green fence may be your better option. Among the choices of evergreens to plant, Leyland cypress (x Cupressocyperus leylandii) is fastest growing, but is plagued by any of three serious disease problems. An established leyland cypress planted 12 feet apart completely […]

Black Gum Should Be Planted More

  U.S. native black gum (Nyssa sylvatica), aka sour gum or black tupelo, is a medium to large shade tree. A young tree has an attractive pyramidal habit and dependable fall color. In the past transplanting black gum has been an issue, but modern advances in growing and planting practices have been solved. New cultivars […]

Divide Irises In Late Summer

Irises (Iris spp.) are beloved spring flowering perennials. Perhaps some fans and clumps flowered poorly this spring. There are several reasons for this, including: old clumps in need of dividing, weather issues, poorly drained soil, inadequate nutrition, too much nitrogen fertilizer, heavy shade, and pest and disease problems. Irises do not compete well for space […]

Re-blooming Iris For Twice (and More) Flowering

Gardeners who desire more flowering from garden iris (Iris spp.) should be planting re-blooming types. Some cultivars may re-bloom up to three times in one growing season. The re-blooming trait is found both in bearded and beardless irises (I. germanica). Re-bloomers need to be well established for one year, sometimes two, to bloom multi-seasonly. Some […]

Complete Care of Tall Bearded Iris

Most gardeners plant tall bearded iris from late August through October to insure good root development before winter sets in. Spring planting is another option as iris may be purchased in containers. Bare root rhizomes need to soak overnight in water before planting. Bearded irises prefer a sunny location and a slightly acidic well-drained soil. […]

Ornamental Peppers Sizzle In Autumn

   Some gardeners call them “Christmas peppers”. In the late summer garden all eyes turn away from most flowering annuals and to the colorful fruits of ornamental peppers (Capsicum annuum). Many are dwarf red hot chili peppers. (No!…not the rock band). Fruits are cylindrical or ball shaped and the brilliant colors range from white, yellow, […]

Stewartia- A Tree for All Seasons

    Japanese stewartia (Stewartia pseudocamellia) is a truly beautiful 20-30 foot small tree or multi-trunked shrub. Stewartia may be finicky to grow, but a great plant nonetheless. Although rarely seen in U.S. gardens, Japanese stewartia is the most commonly grown of the six stewartia species. All are winter hardy in the Southern Appalachian region (USDA zones 6 […]

Growing Spuria Iris Worth The Challenge

photos courtesy of Iris City Gardens Jimmy Turner, Dallas Arboretum horticultural guru, gave me this idea. Growing spuria iris in the Southern Appalachian region can be quite challenging. Hardy to USDA zone 5, spurias are dormant (asleep) during our usually hot, dry summers. A wet summer is a real “downer” for spurias.Spuria irises bloom two […]
