Lacebark Pine – A Year-round Treasure

Native to China, lacebark pine (Pinus bungeana) is an excellent, low-maintenance evergreen treasure. Winter-hardy in USDA hardiness zones 4-8, this specimen pine struggles in the summer heat and humidity of the Southern U.S. Best specmens are found growing in arboretums and botanical gardens north of zone 8. This 3-needle pine offers 4-seasons of ornamental interest. […]

Prepare For Storm Damage

A snow/ ice storm is both a beautiful and horrific scene in a landscape. Costly tree/shrub breakage, downed power lines, and subsequent utility shutoffs may be staggering results. Don’t feel powerless! Prepare and take action.  During the storm, do nothing / “hands off”. Working near an active electrical line is deadly. After the storm you should immediately […]

Dependable Conifer Trees For Southeast U.S. Landscapes

Arizona cypress (Cupressus arizonica var. glabra) is a southwestern U.S. conifer tree that is often underplanted. Soil drainage is an absolute must! Growth rate is moderate (15 feet high after 10 years) and eventually will reach 30-50 feet at maturity. (zones 7-9). I have seen multi-year specimens thriving in zone 6b. Deodar cedar (Cedrus deodara) is […]

Some Conifers Don’t Like Summer Heat And Clay Soils

Most conifers are best grown in deep, moist, well-drained, acidic loamy soils and in full sun. In the deep South evergreen conifers are challenged by warm soils, poor soil drainage, and humidity. Humidity increases their susceptibility to diseases. Once established they are drought tolerant, but most fail in poorly drained wet soils. Many pine species […]

ACS SOUTHEAST REGION CONIFER REFERENCE GARDENS*

From Kentucky and Virginia south to Florida, 19 public gardens were now participating in the program. Two of the latest additions are Brookgreen […]

Conifers for Small Garden Spaces

Some properties can not accommodate the enormous size of tall evergreen trees. In the world of conifers, a select number of genetically dwarf species and varieties are better fits for small spaces. Most evergreens are sun lovers and require a well-drained soil. Mulching around trees and shrubs also benefits to conserve soil moisture and keep roots cool. […]

Eastern White Pine Losses Continue

Environmental and pathogenic problems continue to take their toll on Eastern White Pine (Pinus strobus). This valued landscape and lumber tree is native in the Eastern U.S. and Canada (USDA zones 3-8). Climate change is likely contributing to recent losses of white pines due a number of serious disease and pest problems that are reducing tree numbers. Pests: A […]

Buying/Planting A Live Christmas Tree

A living Christmas tree—one that’s planted outdoors after the holidays—has become a tradition with many families to commemorate a birth or someone’s passing. Purchase a live Christmas tree and plant it in your landscape after the holidays. Pre-dig a planting hole ahead because outdoor weather may not be suitable for digging. For safety sake, fill it with leaves or mulch to prevent freezing or […]

Lacebark Pine Is An Arboreal Gem

Lacebark pine (Pinus bungeana) is an arboreal gem which few gardeners are privileged to own (USDA hardiness zones 4-8). Hopefully, this will change. Lacebark is a lovely 3-needle pine with exquisite exfoliating bark which becomes more attractive as it ages. Bark mottling begins after 8-10 years, that’s worth the wait if you’re a young patient […]
