The Spotted Lanternfly (SLF) is an invasive pest that poses a great threat to California's agriculture. It was first discovered in the U.S. in Pennsylvania in 2014 and has since taken the east coast by storm, causing damage to many plant species and proving to be difficult to control. Although this pest hasn't been found in California, it is important to keep an eye out to catch an invasion early.
What does the spotted lanternfly look like?
The SLF adult is about 1 inch in length with grayish wings, black spots, and red hind wings. Egg masses are laid in the fall on the east coast and resemble splotches of mud. They are often laid on smooth surfaces like branches, rocks, or outdoor furniture. Early nymphs are very small, wingless, and black with white spots. The last nymphal stage is 1/2 inch long and red with white and black markings.
What damage does the spotted lanternfly cause?
On the east coast, the spotted lanternfly's preferred host is the invasive tree-of-heaven (Ailanthus altissima), but it will also feed heavily on grapes, maples, willows, and birch trees. SLF feeds on plant sap and excretes honeydew, which can cause sooty mold to grow on leaves and fruit. It is known to kill black walnut saplings, tree-of-heaven, and grapevines. However, for most other plants SLF is considered a plant stressor and healthy plants can usually tolerate feeding.
What can you do to help keep the spotted lanternfly out?
Spotted lanternfly is easily transported to new areas as egg masses on firewood, stone, cars, and furniture. Check vehicles and trailers when traveling to areas where SLF has been confirmed. Inspect items purchased or shipped from these areas, and don't move firewood. Familiarize yourself with the various ways that SLF egg masses may appear and report any potential sightings to the CDFA Pest Hotline: 1-800-491-1899.

As California Invasive Species Week (June 3-11) approaches, it's time to raise awareness about the impact of invasive plants on our natural ecosystems and the importance of making informed plant choices. Invasive species can have detrimental effects on local flora and fauna, often outcompeting other plants for resources and disrupting local ecosystems. By selecting plants that are well-suited to your environment and not invasive, you can make a positive contribution to preserving California's diverse landscapes.
Many invasive plants can be aesthetically pleasing and low-maintenance, making them a popular choice for gardeners. However, invasive plants can spread rapidly, taking over natural habitats and causing significant environmental damage. Invasive species often have few natural predators, enabling them to grow uncontrollably and outcompete other plants for resources like water, sunlight, and nutrients. This can lead to the loss of biodiversity, reduced habitat quality for wildlife, and increased risk of erosion and wildfires.
Examples of Invasive Plants in California:
1. Periwinkle (Vinca major) - This evergreen groundcover is a popular species because of its beautiful purple blooms. Periwinkle forms dense mats that can smother native plants and alter soil chemistry. Instead of periwinkle, try planting native groundcovers like California lilac (Ceanothus spp.) or hummingbird sage (Salvia spathacea).
2. Fountain grass (Pennisetum setaceum) - This ornamental grass is highly adaptable and has invaded many natural habitats, including grasslands and coastal sage scrub. Instead, opt for native grasses like purple needlegrass (Stipa pulchra) or deergrass (Muhlenbergia rigens or the smaller version Muhlenbergia dubia).
3. Pampas grass (Cortaderia selloana) - A tall, clumping grass with feathery blooms that can quickly dominate landscapes and outcompete native species. Consider planting native ornamental grasses such as blue grama grass (Bouteloua gracilis) or switchgrass (Panicum virgatum) as alternatives to pampas grass.
4. Tree of heaven (Ailanthus altissima) - This fast-growing tree can release chemicals that inhibit the growth of other plants and can sprout vigorously from root fragments. Plant California native trees like sycamore (Platanus racemosa) or western redbud (Cercis occidentalis) instead of the invasive tree of heaven.
As we celebrate California Invasive Species Week, remember the importance of choosing native plants for your garden. By doing so, you can preserve biodiversity, and contribute to the overall health of our communities. The UC Master Gardener Program is a resource for guidance and education in sustainable gardening practices, including the selection of non-invasive plants. By working together, we can protect California's rich and diverse landscapes for generations to come.

The upcoming Paul Schrader film, "Master Gardener," fuses the gripping elements of a thriller with the serene world of horticulture, crafting a narrative that contrasts the real-life commitment of a UC Master Gardener.
The drama “Master Gardener” brings to the screen the journey of meticulous horticulturist, Narvel Roth (played by Joel Edgerton), whose tranquil life at Gracewood Gardens - a magnificent estate managed for wealthy dowager Mrs. Haverhill (Sigourney Weaver) - gets entangled in a web of dark secrets with the arrival of Mrs. Haverhill's troubled great-niece, Maya (Quintessa Swindell).
This film draws parallels between this captivating story and the dedication of real-life UC Master Gardeners, who are similarly committed to fostering growth, not just in gardens, but also in their communities. The intriguing blend of thrilling drama with the art and science of gardening provides a fascinating backdrop to the film. Interestingly, it's also a nod towards the real-life commitment and expertise demanded from UC Master Gardener volunteers.
In the real world, becoming a UC Master Gardener isn't about unlocking dark secrets but rather about unlocking the secrets of nature. It requires a willingness to learn, dedication, and a keen eye for detail – traits our fictional Master Gardener, Narvel Roth, seems to have.
The journey to becoming a UC Master Gardener can be as intriguing (though, fortunately, far less dangerous!) as the plot of Schrader's film. Joining the UC Master Gardener Program begins with robust training with 50 hours of instruction in horticulture fundamentals. From understanding plant biology, integrated pest management, soil health, to irrigation principles, the learning curve is steep but rewarding.
Much like Narvel, UC Master Gardeners in real life spend a significant portion of their time nurturing gardens and landscapes. They are deeply committed to the plants in their care, developing a bond that might seem strange to those who don't share this passion. However, the role of a UC Master Gardener extends far beyond gardening for personal enjoyment. They are volunteers at heart, dedicated to sharing their knowledge with their community. This might involve educational programs, workshops, or community garden projects – a far cry from the chaos that descends upon Narvel and his new apprentice.
The film, as thrilling as it promises to be, paints a stark contrast to the joyful, community-focused reality of a UC Master Gardener. Yet, both convey the same underlying message: gardening is a serious commitment and a lifelong passion that can require dedication, patience, and constant learning.
So, as we await the edge-of-the-seat suspense and drama of "Master Gardener," let's raise a toast to the real-life UC Master Gardeners who, amidst their toil with soil, seeds, and shears, continue to bring beauty, knowledge, and growth to our communities. Without the added drama, of course!
If you are interested in learning more about becoming a UC Master Gardener volunteer, please visit our website at mg.ucanr.edu/findus, and connect with your local county program. Here, you'll find information about the next training class and how to take the first step toward becoming part of the UC Master Gardener community.

It's California Wildfire Preparedness Week 2023 (May 1-8), it serves as a crucial reminder of the importance of preparing home landscapes to help mitigate wildfire risks. With the increasing threat of wildfires in California, adopting preventive measures and adapting landscapes can significantly reduce the vulnerability of homes and communities.
UC ANR fire and natural resource advisers developed strategies for homeowners to make adjustments for a home that is more resilient to wildfire.
Design and implement a defensible space:
- Create fuel breaks surrounding your house and within your garden.
- Create space vertically and horizontally via plant placement and pruning.
- Use hardscape and noncombustible materials around structures and to separate individual plants and groups of plants.
- Use the right plants in the right places with fire, climate, and irrigation needs in mind.
- Create plant islands that have similar sun, nutrient, and water needs.
- Replace combustible gates that attach to the house with materials that will not burn.
Maintain your landscape:
- Keep your garden free from dry and dead wood, dry grasses, and leaf litter, especially near any structures.
- Prune plants to provide horizontal and vertical space throughout your garden and surrounding structures.
- Eliminate fire ladders. A grass fire can move up into shrubs and then into trees.
- Hydrate plants with a water-wise irrigation system. Use non-combustible mulches near the house.
Fire-resistant landscaping is a critical aspect of wildfire preparedness. The UC Master Gardener Program plays a vital role in educating and assisting Californians in creating fire-resistant landscapes and implementing best practices to protect their properties. UC Master Gardener volunteers help guide homeowners in designing and maintaining their landscapes to reduce fire risks. Planting fire-resistant ground covers, shrubs, and trees, as well as maintaining proper spacing between plants and removing dead vegetation can significantly minimize the spread of wildfires.
California Wildfire Preparedness Week 2023 serves as a reminder of the importance of creating fire-resistant home landscapes to protect our communities from wildfires. UC Master Gardener volunteers help provide education and assistance to homeowners through community workshops, webinars, and other outreach events. For information on an event or workshop near you connect with your local UC Master Gardener Program by visiting: https://mg.ucanr.edu/FindUs/.
By working together, we can foster wildfire preparedness and resilience, ensuring the safety of our communities in the face of increasing wildfire threats!
