My calendar says November but the weeds in my garden think it’s spring. That nice rain last month followed by warm, sunny days has prompted them to grow like, well, weeds and that’s not good news for my winter crops.
What’s a gardener to do?
Like so many other gardeners, I turned to the folks at the UC Davis Weed Science Program. Housed in the UC Davis Department of Plant Sciences, the “weeders” are experts at helping growers and gardeners improve plant production by controlling weeds.
What are the most effective organic tools for controlling weeds? That’s what I, and thousands of others, want to know. You don’t have to be an organic grower to seek organic tools for fighting weeds. Synthetic herbicides come with...

Synthetic soil fumigants such as chloropicrin and 1,3-D are used by some commercial growers to control soilborne pathogens, weeds and nematodes prior to planting strawberries, onions, tomatoes, eggplant, peppers and spinach.
These fumigants and all other biocidal products with the potential to harm the environment and human health are highly regulated by the federal Environmental Protection Agency, the state Department of Pesticide Regulation, and county agricultural commissioner's offices.
UC Cooperative Extension farm advisor Oleg Daugovish and his collaborators work hard to find effective, environmentally safe and economically viable ways to...

The U-pick strawberry fields at Swanton Berry Farm near Davenport on the coast are formally opening on May 28, but if you drive out there now, you’ll get a chance to pick without a crowd. Talking to Barrett Boaen, the U-pick manager, I got to the bottom of just why their berries, also sold at local Whole Foods stores, look and taste so good.
Partly it’s the ‘Chandler’ variety, chosen for its old-fashioned sweetness and flavor although it yields only about two-thirds as well as some varieties. It’s also about not pumping up production with too much nitrogen or irrigation (more details here). Mostly,...

Well before Safeway launched a line of organic products or Craigslist posted openings for school garden coordinators, UC Santa Cruz was training students for careers in organic farming.
The UC Santa Cruz Apprenticeship in Ecological Horticulture started in 1967 when the concept of organic was in its infancy. Forty-three years later, organic has gone mainstream and the apprenticeship program is more popular than ever.
A recently published study looking at the apprenticeship’s last 20 years found that a large percentage of its alumni are still involved in growing and marketing organic food and teaching...

While numerous studies have shown that organically grown foods contain fewer pesticide residues, there has been little convincing scientific evidence that organic crops taste better or are more nutritious.
Now a two-year evaluation of California strawberries has found that organic strawberries, while lower in phosphorus and potassium, had significantly higher “antioxidant activity and concentrations of ascorbic acid [vitamin C] and phenolic compounds, longer shelf life, greater dry matter, and for ‘Diamante’, better taste and appearance” than conventionally grown berries.
The study has been getting a lot of media attention, including coverage in the
