This summer, the media frequently reported an increase in the density of pests in the home and landscape. The drought has been cited as the cause of these problems. Pest control companies quoted in articles confirm that the demand for their services is much higher this year than in years past.
Many people are asking, “Why are there so many more pests this year than usual?” According to Dr. Andrew Sutherland, the urban Integrated Pest Management Advisor for the San Francisco Bay Area, we are asking the wrong question. “The overall abundance of pests probably hasn't changed and may even have decreased as compared to wet years. The real questions we should be asking are ‘Why are these pests appearing earlier...

Weeds don't just look unsightly, they also rob other plants of water, says a UC Agriculture and Natural Resources (UC ANR) expert in a new water conservation video released today.

Although pine trees are comparatively drought tolerant, there comes a point where even hardy trees become stressed by lack of water. Stressed pines frequently exhibit symptoms such as thin, slightly yellowish canopies, or roots that "spider" across lawns (Figure 1). By the time pine trees begin turning brown, they are usually dying, but with some precautions, many trees can be saved before they reach this point.

August 22nd is National Honey Bee Day so we thought we'd repost one of our previous articles that discussed ways gardeners can help protect honey bees.
Most people have heard about the decline in honey bees (Figures 1 and 2) during the last several years and want to help. Gardeners and landscapers who want to help protect honey bees can do so by learning more about the factors that cause bee decline and by practicing Integrated Pest Management or IPM.

A recent find in El Dorado County has weed scientists, land managers, foresters, botanists, and plant conservationists throughout Northern California very excited over a tiny mite.
The broom gall mite has recently been observed attacking the invasive plant Scotch broom (Cytisus scoparius) in California's natural landscapes. Scotch broom, desired for its bright yellow flowers and rapid growth, was first introduced into North America as an ornamental and for erosion control..../span>
