Hydrilla (Hydrilla verticillata) is an invasive, aquatic weed that can be found in many slow-moving fresh water bodies in California. The plant forms large mats that can crowd out native plants, restrict water flow, and interfere with boating and fishing. These mats can reduce habitat for fish and other wildlife, degrade water quality, and increase the risk of flooding.
Hydrilla is easily spread since it often breaks apart into tiny pieces that can each produce new plants. It also produces special survival structures on the stems (turions) and in the sediment (tubers). Each tuber can produce a new plant. The tubers can survive up to seven years in the sediment before sprouting, even if no water is...

In this blog article we answer some frequently asked questions about moles, voles, and gophers and their management.
How can I tell if I have moles, voles, gophers, or something else?
Moles: look for circular or volcano-shaped mounds with the plug in the middle, or a plug may not be apparent. The soil of mole mounds tends to be clumpier than gophers. Moles sometimes leave a raised ridge just beneath the soil surface while hunting for food.
Voles: look for aboveground runways that connect burrow openings. Grass usually covers the burrows. Voles can girdle trees...

After years of drought, we welcome rain in California. But we also recognize that rain can help spread a number of plant diseases. Rain and wind can splash bacteria and fungi from infected leaves, branches, and blossoms to uninfected parts of the tree. The fungal diseases anthracnose, peach leaf curl, scab, shot hole blight, and the bacterial disease fire blight can all be spread by rain splash. This ability to spread by water makes these diseases more common after a wet spring. With 2023 bringing quite a bit of rainfall and 2024 looking similarly wet, we want to focus on some common rain-dispersed diseases.
Anthracnose
Anthracnose affects many trees including almond, citrus, Chinese elm, and...
