Leaves of some landscape trees turn yellowish- green color in the summer. The common cause for this malady is a lack of minor nutrients (“micronutrients”) that are essential for plant growth. These nutrients are available in the soil in very small quantities. Nutrient deficiencies are not common, except in the high pH soils, particularly the […]

Birds visit trees, shrubs, and vines for five things: fruits (berries), sweet nectar (flowers), insects (particularly caterpillars), nuts and seeds, and shelter. This list is a compilation from the North Carolina and Tennessee chapters of the Audubon Society of ornamental plants common in the Southern Appalachian region.

Most perennials demand well-drained soil. They perform poorly or die out when in ground that is constantly wet and soggy. However, a small number of perennials tolerate and even thrive in moist soils. Most plants listed here are all hardy within zones 5-8, and grow best in moist, humus-rich, well-drained soil. Most are okay getting their feet (roots and crown) wet for […]

Posted by Hugh on February 6th, 2020
In general, the garden soil pH fluctuates only slightly unless you accidentally spilled fertilizer or limestone. Soil pH is also affected by rainfall patterns, decomposing organic matter, and bacterial activity in the ground. In the eastern U.S. rain water is slightly acidic. Acid rain is the result of these pollutants (mostly sulfate and nitrate) from […]

Posted by Hugh on February 1st, 2019
Adding large amounts of compost or organic matter to a planting hole greatly improve the soil’s water-holding capacity and aeration. Simply throwing piles of leaves into the bottom of the planting hole helps improve a soil. However, amending the planting hole is not recommended by most plant experts. Why? According to soil scientists, the plant roots stay locked within the rich […]

Weeping forms of willows (Salix spp.), flowering cherries (Prunus spp.), pines (Pinus spp.), spruces (Picea spp.) and European beeches (Fagus sylvatica) are magnificent landscape features. Weeping forms of evergreen and deciduous trees develop strong upright central leaders, and their outward branches cascade downward. Among conifer species there are over 150 different cultivars with pendulous habits. Here is a list of 28 weeping tree species. I […]

First of all, there is no perfect tree, either for a street or landscape planting. However, many excellent cultivars are now available at local nurseries and retail garden centers. Select one that matches your site requirements. Site factors include: amount of sunlight daily, soil type, soil pH (acidity or alkalinity), and soil drainage. What kind of […]

Across the U.S. and Canada, city planners, landscape architects, and property owners now enjoy a wide selection of landscape trees to plant on city streets, along roadsides, and in yards and gardens. Over the past half century new and improved varieties (cultivars) are disease and pest resistant and exhibit better branching and architecture. We now know to avoid […]

In general, most species of our native birches (Betula spp.) grow best in cool, northern areas of the U.S. They are found growing along the sides of rivers, lakes, streams, and mountainous areas (USDA Zones 4-9). Most birches (not all) are recognized for their distinctive gray to white bark. Birch species with the whitest of bark […]
