The Boys Or Girls of Summer

Gardeners are looking for simple plant combinations and this photo, shot at Kingwood Center in Mansfield, Ohio, shows three easy to grow perennials, “no-brainers” as some might call them. Originally, all three plants emigrated from the prairie where each coped with hot summers without much rainfall. In the hands of modern plant breeders, each perennial has been greatly improved. All are disease and pest resistant. Some […]

Dawn Redwood Is Back From Extinction

  Dawn redwood (Metasequoia glyptostroboides) was thought to be extinct until the mid-twentieth century. In 1948 dawn redwood was re-introduced into North America from Sichuan-Hubei Provinces in China.   Dawn redwood grows in full sun and in well-drained, compost-rich soil. The tree struggles in dry or high pH soils. Dawn redwood will tolerate standing water for a […]

Boxwood Blight Discovered on Pachysandra

In June 2012 plant pathologists at the Connecticut Agricultural Experiment Station have confirmed a natural infection of pachysandra in the landscape by boxwood blight (Cylindrocladium pseudonaviculatum), the boxwood blight fungus. The infection originated from recently installed balled and burlapped (B&B) boxwood plants. A plant inspector in Fairfield, CT noticed that an established bed of pachysandra […]

‘Morning Grace’ Spiderwort Is A Delicate Beauty

  Morning Grace spiderwort (Tradescantia rosea ‘Morning Grace’) is a short growing spiderwort native from Maryland south to Florida. Its small size and clumping nature makes it a wonderful rock garden plant. It grows into 8″ tall x 8″ wide clump of narrow medium green leaves. At first glance this spiderwort’s foliage appears very grass-like. […]

Yellow Nutsedge Control Is In Your Hands

Yellow nutsedge, aka “nutgrass” (Cyperus esculentus) is a nasty weed found in lawn and garden areas. It is a sedge, and not a grass, and methods of eliminating it vary. Yellow nutsedge is easily identified by its yellow to light green glossy leaves and the triangular shape of the stem. It grows most actively during […]

Hollyhock Rust Prevention Tips

There are numerous cultivars differing in plant height from 5 to 9 feet and spread of 1 to 3 feet. Flowers come in single and double forms and in many color shades. Hollyhocks are hardy to USDA hardiness zone 4. […]

‘Sunburst’ Golden St. John’s Wort

Our native golden St. John’s wort (Hypericum frondosum) deserves more planting space in U. S. gardens (USDA hardiness zones 5-8). ‘Sunburst’ is the leading cultivar and exhibits superior traits over the species. Golden St. John’s wort forms a small, dense growing deciduous shrub, noted for its showy golden yellow flowers and attractive blue-green foliage. Sunburst grows more compact […]

‘Brigadoon’ Hypericum Wakes Up a Garden Bed

The bright chartreuse (almost golden) foliage Brigadoon St. John’s wort (Hypericum calycinum ‘Brigadoon’) can brighten up almost any dull garden spot. This Euro-Asian ground cover thrives in any well-drained soil under full to partial sunlight (USDA zones 4-7). Full sun may burn the summer foliage in zone 7. ‘Brigadoon’ grows 12 to 16 inches tall and spreads […]

Selecting The Right Ivy For Your Garden

Have you taken the “No Ivy Pledge”? I have not. In an effort to slow defections from growing ivy, the American Ivy Society has developed a list of non-invasive cultivars. It includes several dwarf English ivy cultivars (Hedera spp.). Add a little water and fertilizer and these mini-ivies do not miss a beat. Mini- ivies […]

Promising Hemlock Adelgid Research

Proper care of hemlock trees is important for their survival. Hot dry summer weather appears to slow population growth. During periods of severe drought, shallow rooted hemlock trees should be irrigated. Prune dead and dying branches from trees to promote new growth. Also, limit the amount of nitrogen fertilizers to hemlock(s), as it promotes heavier […]
