Posted by Hugh on October 21st, 2021
Containers filled with shrubs and perennials, doesn’t necessarily ensure their winter survival. Without adequate cold protection plants may succumb to cold injury—turning them into dead annuals. To over-winter perennials in containers, you need to know their root and shoot temperature hardiness. Often, plant hardiness ratings is listed on the label. Roots and shoots of several […]

Some aggressive perennials like Chameleon plant (Houttuynia cordata), variegated Bishop’s weed (Aegopodium podagraria), along with many woody briars can be extremely difficult to eliminate from a landscape area or garden bed. If a weedy garden bed contains no desirable plants, you can over spray weeds with glyphosate, a nonselective herbicide.(Roundup™ is common trade name). This […]

Posted by Hugh on January 20th, 2019
Many landscape plants die because they were planted in soil that was too wet or soggy. Poorly drained soils are generally poorly aerated. A high water table in an area limits your choices of plants that you may grow. Plants that grow naturally along streams and ponds are good candidates for poorly drained sites. During periods of heavy […]

Posted by Hugh on December 24th, 2018
Winter foliage burn on evergreens is often most prevalent on boxwoods (Buxus), hollies (Ilex), rhododendron, and many kinds of conifers. Symptoms often develop when temperatures warm up in late winter and early spring. This type of winter damage is often misdiagnosed as an infectious disease or damage from excessively cold temperatures. Evergreens transpire (lose water […]

Eventually, all potted plants outgrow their containers. This includes potted roses, Japanese maples and other small trees, shrubs, dwarf conifers, elephant ears (Colocasia, Alocasia), cannas, lotus, papyrus, and lots more. A rule of thumb is to transplant every 2 years in early spring before bud break. In the case of perennials and tropicals, this is a good […]

Posted by Hugh on July 7th, 2017
Leaf scorch or foliage burn is caused primarily by environmental stress factors such as drying winds, drought, mechanical root injury, and winter injury . Natural pathogens, such as viruses, fungi, or bacteria, can be secondary causes. Spraying the wrong pesticide or accidentally allowing spray to drift onto a nearby susceptible landscape plant can result in chemical foliar […]

Posted by Hugh on May 20th, 2017
Long term drought can be devastating on landscape and woodland trees. An environmentally stressed tree must expend additional energy to survive. Extremes of drought leads to decreases in trunk diameter and height growth, declining resistance to pests and diseases, less food production via photosynthesis, and in flower and fruit production. Symptoms of drought stress include wilted […]

Native to China and Japan, winter or fragrant daphnes (Daphne odora) open to light pink or white flowers in winter and early spring in the southeastern U.S. and Pacific Northwest (USDA hardiness zones 7-9). Their welcome floral fragrance will pervade through your garden for nearly two weeks starting in late winter. Winter daphnes grow 3 to 4 […]

Rabbits make their homes in brushy areas such as along fence rows or untended areas between neighboring yards. They frequent nearby yards and gardens, perhaps your own, in search of vegetation to eat. Most people, particularly young children, adore them but a cute bunny can cause lots of damage in a flower /vegetable garden or […]
