Master Gardener Program, UC Cooperative Extension, Los Angeles County

Master Gardeners are volunteers from the community who are trained by the University of California Cooperative Extension specialists and other qualified instructors using research-based information to promote environmentally responsible and sustainable horticultural practices in the home, community and school landscapes. Master Gardeners extend research-based information by conducting workshops an

d demonstrations, diagnosing plant and pest problems, speaking to community groups, educating teachers and parents at school gardens, and answering gardening questions at fairs and farmers markets as well as our email and phone helplines.

Every year in May, the UC Master Gardeners of Los Angeles County participate in the Bug Fair at the Natural History Museum. Our volunteers provide crucial information about invasive pests that threaten our urban trees. This team participates at events throughout the year at various locations. The Bug Fair draws huge crowds of all ages.

My carrots always seem to come out stumpy. This year was no exception. Maybe it happens to you too. There are a few reasons this happens:
• The soil is too rocky, compact, or rich, leading to short, forked roots and plants diverting energy to leaf growth.
• Watering inconsistently or too much, which leads to splitting and deformation.
• Overcrowding from skipping thinning causes carrots to compete for resources and come out deformed.
• Pests such as carrot fly and nematodes can cause deformation and forking.
• Too much heat can lead to bolting, and diversion of resources to the stems and leaves over the roots.
I probably experienced a few of these issues at once. My soil was likely too rich, they probably got too much water, and it was an unusually warm winter. Oops!

The Spring 2026 Grow LA Gardens site at Niemes Elementary Nature Center in Artesia showcased a small class of seven students who paired classroom lessons with hands-on work in the one-acre school garden. They harvested spent spring crops, saved seeds from calendula, cilantro, and broccoli, and learned the importance of healthy soil — with the worm bins proving especially popular. Watching the full cycle from seed to harvest and observing a thriving, seasonal garden inspired students to bring these practices to their own spaces.

lanta-born Master Gardener Dena Brummer learned early-on the importance of the phrase, “bloom where you are planted."

“I’m a military brat and have moved 21 times, so home has always been wherever my shoes are. I like to say I’m a daughter of the South and a woman of the West."

While being uprooted was a constant during Dena's youth, she found consistency in food, gardening, and hospitality - and those early experiences shaped her lifelong relationship with the land. Now a resident of Pasadena, she says she is “rooted in community spaces across the region.“

Dena first learned about the MG program while working at Muir Ranch at John Muir High School. “At the time, the ranch hosted Master Gardener training classes, which was my first introduction to the program. Seeing the depth of knowledge and the spirit of community education really stayed with me and planted the seed for me to apply."

Food systems were important to Dena when she applied to the MG program. “I came into the program with a strong interest in food-growing systems - especially edible gardens and how they intersect with community health and food access."

Dena says the MG program helped transform the way she gardens. "It helped me move from gardening intuitively to gardening with a deeper understanding of the underlying science. I now think much more about soil biology, ecological relationships, and long-term sustainability in the spaces I steward."

Since graduation, Dena has volunteered with several programs focused on helping people learn how to grow and cook their own food. “I’ve applied much of what I learned through several community programs I’m involved in. I teach a gardening course called Seeds to Supper in partnership with the Pasadena Public Library, and I also help lead Grow LA workshops at the Altadena Community Garden."

One native plant Dena's digging right now? “I’m really drawn to California buckwheat. It’s incredibly resilient, beautiful in a quiet way, and it supports so many pollinators. It reminds me that gardens can be both productive and deeply supportive of local ecosystems."
