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.

Over the past few weeks there have been numerous reports of bug invasions near Ridgecrest, Inyokern, and other cities in the high desert of eastern Kern County, California. Residents and business owners have reported large aggregations of bugs within their homes, businesses, and on the streets. There have been no reports of damage to agricultural crops, landscape plants, or people. However, the nuisance and paranoia associated with bugs crawling on business walls and people has led to numerous inquiries into what is going on and how long it will last.

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.
California has a number of native bark beetle species that individually do only minor damage as they...

Water applied to landscapes is estimated to account for about 50% of residential water consumption statewide, but the amount varies from about 30% in some coastal communities to 60% or more in many inland suburban communities.
Q. Does a landscape have to...

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.
Any loss of water is a concern as California's fourth summer of drought comes to a close. Missy Gable, director of the UC Master Gardener Program, suggests removing weeds so they won't compete with ornamental plants or edible vegetables.
If weeds are scattered throughout your yard and mixed in with plants, hand-weeding is probably the best eradication method. Cultivation can damage ornamentals with shallow roots, bring weed seeds to...
