An unusual swelling on trunks of trees and occasionally on large branches are “burls”. They’re round, swollen-looking growths on tree trunks and large scaffold branches. Should or shouldn’t you be concerned? Burls are not uncommon and can be found on cherry, maple, oak, buckeye, ash, willow, locust and walnut in Eastern forests. Root burls may […]

Comments Off on Burls on Tree TrunksWhy My Tree Turns Yellow in Summer
Posted by Hugh on August 27th, 2022
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 […]

Your garden should be a year-round enjoyment and you should design it to reflect that. Many trees and shrubs offer multi-seasonal attraction. Several years back I designed a series of walking paths to network through my garden to capture its 12-month natural beauty. Planning next year’s garden? Look for calendar gaps in your own landscape […]

Posted by Hugh on August 16th, 2020
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 October 31st, 2019
Through the fall and winter seasons, certain landscape and woodland trees retain their dead brown leaves on branches. Beech (Fagus spp.) and oak (Quercus spp.) are two common examples. Winter winds and precipitation will eventually force leaves to drop. Plant scientists term the retention of leaves as “marcescence”. There are many theories as to why […]

Posted by Hugh on October 11th, 2019
Fall leaf colors of woodland and landscape trees vary from one year to the next. Foliage colors are determined by monthly weather conditions and several environmental factors. Rainfall amounts and daily temperature levels during August and September are key determining factors. Best autumn leaf colors develop as daytime hours are shortening, daytime hours are sunny and […]

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 […]

Posted by Hugh on January 15th, 2019
Medium to large shade trees increase the value of your property. Their summer shade and wintry wind protection may also reduce utility bills by 20 to 25%. Trees attract wild birds for nesting, protection, and as a food source. Some deciduous species will brighten up the landscape with dazzling fall color. Choosing a fast growing tree, yet some may not […]

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 […]
