I ran across a Weed Science Society of America (WSSA) press release from last summer that I found interesting.
The article, entitled "The Deadly Problem of Poisonous Weeds", outlines ten poisonous weeds in North America that are particularly dangerous and features information from UC Davis Cooperative Extension Weed Specialist Joe DiTomaso.
The article includes basic information on the toxicity, identification, and links to photos of::
1. Poison hemlock
2. Waterhemlocks
3. Oleander
4. Bittersweet nightshade
5. Common pokeweed or pokeberry

After an extended cool and wet spring, we are finally getting summer-like weather in most of the Central Valley. If your garden and home landscape are like mine, now is the time of the year where the winter weeds are winding down and the summer weeds are coming in to take their places.

Early winter is is a good time of year to talk about another landscape weed problem - catchweed bedstraw (Galium aperine) also known as cleavers in much of the rest of the world (among many other names).
In California, bedstraw is summer or winter annual and we are starting to see the beginning of the winter germination flush in the Davis area. We usually see a lot of bedstraw germiantion in the early winter after the rain starts and the soils start to cool; however, there is often a secondary flush of germination in the late winter and earlys spring (Feb-March). Bedstraw will grow into the summer but really doesn't do very well in the hottest times of the year. It tends to complete its lifecycle by...

Recently I was reminded that there is no more important fundamental to weed control than being able to identify your weed problem.
This summer, I moved to a different house and have slowly been working on little projects that arise. One of these has been figuring out what weed problems I bought along with the house – in my case, this has (so far) turned out to be creeping woodsorell (Oxalis corniculata) in my lawn areas and Bermuda buttercup (Oxalis pes-caprae) almost everywhere else (beds, garden, potted plants)! I’ll save my trials and tribulations with Oxalis management for another day; however, UC-IPM has a nice pest management guideline on Oxalis authored by LeStrange, Elmore, and Cudney here:
