How Does A Community Garden Grow?

Gardening is often thought of as a solo undertaking, working by oneself, planting, tilling, raking, dead heading flowers, yet eight years ago, UC Master Gardeners of Yolo County were instrumental in creating The Winters Community Library Teaching Garden (located at 708 Railroad Avenue). Lead by UC Master Gardener Stephanie Myers and accompanied by the dedicated work of UC Master Gardeners, volunteers, and local organizations the site became a garden for the community.

 

Recently, the Winters Community Library Teaching Garden was selected as one of the forty plus tour gardens on the 13th Annual Gardens Got Natives Tour coordinated by the Sacramento Valley chapter of the California Native Plant Society (CNPS). This year’s tour is on Saturday, April 18th and Sunday, April 19th from 9:30 AM to 3:30 PM. So how did this garden “grow up” to be a designated site for the Gardens Got Natives Tour?

 

The vision began in 2018 when Stephanie Myers was asked by Winters Friends of the Library (WFoL) to rejuvenate the underutilized plot next to the library and create a teaching garden. They envisioned a garden which provides learning opportunities on low water use plants, plants that provide year-round habitat for pollinators, a space where visitors can sit and enjoy the garden, educational opportunities for school groups, a space to train community members in ongoing garden maintenance, and a place to hold...

How City Parks Can Contribute to Conservation

Diana Herrera, UC Master Gardener, Yolo County


When I began working in regional and city parks two years ago, I started to look at parks differently. I had always enjoyed seeing stretches of freshly cut lawn dotted with trees. I associated that with being outdoors in a space that was well cared for. As I began to take care of those spaces, I realized how problematic many of our landscaping practices are, especially for agencies like parks which often promote values of sustainability and conservation. While I love my job and working for agencies that provide open, green spaces for the public, I believe that we could do better in providing spaces that are also welcoming to the flora and fauna that keep our ecosystems whole and healthy.


What I have noticed in parks is a lack of diversity in plants, an abundance of invasive species, and an overreliance on irrigation, herbicides, and pesticides. Although grass is terrific for picnics and sports, it creates a food desert for wildlife, and it is resource-intensive when it comes to water and labor. The chemicals that are sprayed to control the grass, weeds, and pests pose further issues for the health of the environment. Around the time I started my first park job, I also joined a local conservancy that taught me about habitat restoration. I started wondering: How could I change the way we landscape parks to celebrate our amazing native plant diversity? What could I do to inspire people to reimagine what a...

NUTS! That’s a Lot of Bees

Greg Wessels, UC Master Gardener, Yolo County


Small Bees, Big Industry

Last year, I attended the Almond Conference in Sacramento. Immediately upon entering the rather plain-looking double doors, I was struck by the scale of the floor space. Exhibitors represented a wide range of services, from insurance to heavy-duty farm equipment and technologically advanced sorting machines. As I was strolling around, I saw a particularly interesting piece of equipment. It was an AI-assisted robotic bee box designed to monitor and support a hive. It helps the bees warm up in the morning, allowing them to get a head start on the day. It also has a mechanism that can lift frames out of the hive while a camera scans the brood and adult bees to check for parasites. Any issue can be communicated directly to the operator, who can then respond or apply treatments remotely. If a pesticide application is about to commence, the boxes can be closed to limit contact between the bees and those pesticides. And if that's not enough for you, they are solar powered as well.


Needless to say, I was impressed. I always had this idea in my head that beekeeping was a very traditional business. I imagined people in those netted hats holding a smoke can and puffing smoke around the bees before lifting a frame out and inspecting it in the sun. This really sparked my curiosity about how pollination is managed in modern agriculture. I realized that for equipment like this to even be developed and deployed, the scale of managed pollination must be significant. I had to know more. So I spoke with...

Ask a Master Gardener

This column is written by the Master Gardeners of Yolo County each month. It provides answers to selected questions recently asked by Yolo County gardeners..

QUESTION: I would like to plant tomatoes in my garden this year. What tips do you have? What varieties should I try?



ANSWER: Growing tomatoes in your own garden can be very rewarding. Our long sunny summers and warm evenings create excellent conditions for tomatoes. And while it can sometimes be too hot for tomatoes as well as people, there are ways to minimize the negative impacts of that. With some attention to timing, soil preparation, care, and choosing varieties suited to our climate, you...

QUESTION: I want to plant a shade tree in my front yard. What do you recommend?


ANSWER: Trees lend to yards and neighborhoods not only an element of beauty but just as importantly a cooling offset to the reflective heat created by the cement and concrete of sidewalks and streets. But they’re more than that.


“Trees are investments,” notes the UC Master Gardeners of Marin website. Consequently, asking and answering some questions in advance will...

April Garden Tips

Peg Smith, UC Master Gardener, Yolo County


As gardeners, beginners or experienced, we have a strong spring urge to see what we can add to our collection of plants. Nurseries and plant sales are well stocked; seed racks are replenished; catalogues entice us. The million-dollar question is always will it thrive in our climate and do well in my garden?

 

What resources do we have to find out what is the ‘right plant, right place’ for our gardens?

April Vegetable Planting Guide

Peg Smith, UC Master Gardener, Yolo County


April is a transition month between cool season and warm season crops. As soon as the soil is warm enough transplant tomatoes, peppers, eggplant, etc. Transplants will have enough time to produce healthy vegetative and root growth before the summer heat and fruit production. With warmer temperatures...
