Turf and Landscape Diagnostics

Weeds can be major pests of home lawns. Due to differences in color, leaf size, shape and growth habit, weeds detract from the natural beauty of desirable turfgrasses. Additionally, weeds compete with turfgrasses for sunlight, soil moisture, nutrients and space. Many weeds can quickly become the dominant species in a lawn. We can assist with weed problems by calling our agent and discussing your lawn.

Weed control in the landscape is a tough business. You have to know a lot about the weed in question just to get started!

As in most situations, a picture is worth a thousand words. Go through the sites below, then choose your method of weed control. Remember: healthy, vigorous lawn grass is the best weed deterrent.

 Conservation Garden – Bee, Butterfly and Beneficial Insects

We are dependent upon ecosystem services or “life support services” provided by healthy ecosystems that we rarely recognize. Land managers should undertake the conservation of pollination systems and insects that deliver pest management services. The right combination of plant and floral resources can be used to attract beneficial and pollinating insects, which can reduce pesticide inputs.

Conservation Garden - Bee, Butterfly and Beneficial Insects

More than 70 plant types were evaluated in the Conservation Garden at the University of Georgia Research & Education Gardens at the Griffin Campus. Plants were chosen based on several factors including high production of pollen and nectar, attractiveness to beneficial and pollinating insects, flowering phenology, and availability of floral resources. Plants located throughout the garden were monitored biweekly for one hour. Visual observations consisted of family and order of beneficial and pollinating insects observed, plant or location insects visited, and ecological classification of the insects.

Insect orders observed throughout the garden contain predatory, parasitoid, and foraging species that provide arthropod-mediated ecosystem services such as pollination and pest control. Differences between ornamentals were found with regard to types of insects attracted to a particular plant species.
