U.S. Native Viburnums And Viburnum Beetle Susceptibility

photo -Arrowwood viburnum in late summer A trip to Carolina Native Plants Nursery in Burnsville, NC gave me this idea to list those viburnums which are U.S. natives (USDA Hardiness zones 6 and 7). All are worthy for planting in your landscape in full sun except where noted. All attract birds and other wildlife to […]

Thermotropism in Plants

How cold is it outside this morning? Look out the window….perhaps your rhododendron is telling you. On very cold winter mornings some broadleaf evergreen shrubs, like rhododendron and daphniphyllum in my landscape, droop down and/or curl up. (see photo). This is a specific response by some plants to sub-freezing temperatures, called “thermotropism”.Scientists do not fully […]

Privacy Screening – Avoid Using Leyland Cypress

‘Green Giant’ arborvitae and Cryptomeria (Japanese cedar) have proven more dependable over the years than Leyland cypress across Tennessee, Virginia, North Carolina, and South Carolina. Leyland cypress is susceptible to three serious foliar diseases. Some people love the faster growth of Leyland cypress. Leyland cypress may be weak-wooded, as reported by some gardeners this current […]

Salt Damage on Trees

Winter 2010 lingers on across Tennessee, Virginia and North Carolina. The white coating of de-icing salts over streets and highways can damage many trees and shrubs. Salt spray and salt deposits may also leach into the soil and become equally damaging. Plant species vary in their sensitivity to salt injury.Browning of the tips of needle […]

Ferns in Your Garden

I recommend adding ferns in your shade garden. Ferns offer very fine textured foliage. Plant’em in clumps of three or more. Select the proper fern by your garden site, e.g whether it is likely dry or moist soils. Some grow surprisingly well in full sun, but most prefer partial to full shade. Don’t buy a […]

Big Begonias

The Benary ‘Big Begonia’ series are a hit, “begonias on steroids”, some gardeners may say. Individual flowers are twice that of other bedding begonias. Colors are vivid with three cultivars currently available . ‘Big Rose Bronze Leaf’ is my personal favorite. (pictured) Begonias grow best in well drained, humus-rich garden soil. Provide tender -loving care […]

Princess Lilies — Hardy in Zone 6

Not all alstroemerias are alike. I have been enjoying my Princess lilies (alstroemeria hybrids from Holland) over the past 6 years. They have been surprisingly winter hardy in zone 6-b where I garden. Further south in zones 7 and 8, Princess lilies prefer part sun to partial shade. I grow’em on the east side of […]

‘Sky Pencil Holly vs ‘Dee Runk’ Boxwood

Boxwoods and hollies are mainline evergreen shrubs, utilized for low hedging, privacy barriers. Single shrubs are planted solely for their architectural accent.  Both hollies and boxwoods grow best in moist, well-drained soils and in full sun to partial shade.  Both prefer soils with a pH of slightly acidic to slightly alkaline. Boxwoods tend to be more shade tolerant than […]

Planting Leyland Cypress May Be Big Mistake

If you live in USDA Plant Zone 6-b – 7, planting leyland cypress (x Cupressocyparis leylandii) could eventually turn into a maintenance diseaster in your landscape. Leyland cypress is a green behemoth, too fast and aggressive for most folks to handle. Ask yourself, “do you really need a 60-70 foot evergreen privacy screen around your […]

Beware of Storm Damaged Trees

This past weekend Northeast Tennessee as well as most of the coastal eastern U.S. was hit by heavy snow, 7 inches and more of heavy, wet clinging snow. Many of my neighbors lost electric power, telephone and cable. A driveby survey of tree damage around the neighborhood found that the following tree species suffered the […]
