UC Master Gardeners of Calaveras County

UC Master Gardeners of Calaveras County Master Gardeners are community members who have been trained under the direction of the University of California Cooperative Extension.

The purpose of the University of California Master Gardener program is to extend to the public research-based information verified by UC experts about home horticulture and pest management through our volunteer Master Gardeners. Each volunteer has completed more than 50 hours of formal classroom training. Master Gardeners help the Cooperative Extension office provide practical scientific gardening

information to the home gardeners of our counties. How We Serve our Communities:
Free Public Classes: We offer classes on a variety of topics throughout the year. Master Gardeners are available to answer your questions during breaks and after class. See the class schedule in your county in your county for more information. Weekly newspaper articles: The Mt. Democrat newspaper publishes a weekly Master Gardener column. Read previous articles in our online archive. Information Booths at Local Events: Master Gardeners staff information booths and give demonstrations at various community events. Look for us at your county fairgrounds, the Home and Garden Show, various Farmers Markets, Earth Day Events, Kid's Expo, Farm Day, and more.

Happy First Day of Summer — the longest day of the year and the official start of the season California gardeners have been working toward.

Whether your garden is bursting with tomatoes, buzzing with pollinators, or just getting started, today is worth celebrating.

What's growing in your garden this summer? Share it in the comments!

As temperatures climb, irrigation becomes the most critical task in your June garden.

Two things to do right now:

Check your soil moisture — don't water on a schedule alone. Adjust based on what the soil actually needs.
Water early in the day — the coolest part of the morning maximizes absorption through plant roots and minimizes evaporation.

Warm-season crops like beans, corn, cucumbers, and squash require substantial irrigation. Only plant as many as you can consistently water through the summer.

Questions about watering in your area? Your local UC Master Gardener Program can help — for free. Find your local program at: mg.ucanr.edu

Greetings, Gardeners. The Calaveras County Master Gardeners Demo Garden will be open this THURSDAY for regular SUMMER hours from 9am to 1pm. Summer hours continue through October.

Hoo boy, the hot stuff has arrived for real, hasn't it? Perhaps like us you are upping your watering routines to keep up with all the thirsty plants. The garden is thriving, abuzz with life and activity. We hope you'll visit for fellowship with other garden nerds and to gain inspiration for new things to try at home. You are welcome to ask questions—in fact, we encourage it. We're here to help with science-backed gardening information. Come to the garden and enjoy community with other gardeners (gardenerds?)—and bring your sunhat!

Rest assured we do have some shade for you. Remember the shade cloth project we reported on recently? It's a big job, still in progress, that will give the plants (and us and our guests welcome moderation of the full summer sun.

While you're here, take a stroll up to the orchard to see sunflowers and the fruit trees as they start to bear. Also note the dahlias, shasta daisies, chamomile, and strawflowers in bloom in the nearby container garden.

🌱 The Plant Sale will be open
In the plant sale area, our wide selection of daylilies is popping off beautifully. We have several colors to choose from. Also visit the succulents area to see vividly blooming geranium. In the shade lovers area, there is a marvelous acanthus mollis blooming to ooooo and aaaaah over.

Also look for freshly propagated scabiosa, which can be found in the pollinators area right in front of a bunch of mature scabiosa growing in the garden so you can easily see what they look like full grown and in bloom. This hardy beauty works wonderfully in many landscapes.

Master gardeners spend hours working to propagate various types of plants for the sale area. Occasionally, we get something unusual, such as these ginkgo biloba babies, started weeks ago from a few precious seeds collected by a community member. A fascinating, ancient species famous for its glowing golden fall color, the ginkgo biloba is so ancient, this "living fossil" has few close relatives. It predates flowers. And bees. Amazing! You can read a short essay about this tree that coexisted with dinosaurs here, or take a deep dive on Wikipedia.

We watched over the little nursery tray of planted ginkgo seeds as they slowly germinated and sprouted, anticipating being able to transplant them into individual pots. And finally here they are! They'll be given a chance to recover from their transplanting and then eventually offered for sale.

We regularly stock dozens of kinds of plants for you to browse, including natives and drought-tolerant species, all locally sourced and propagated, as well as a wide and ever-changing variety of pots, planters, collectibles, and vintage items. The selections evolve rapidly; if you need help finding things, we are here to help; just ask!

All sales help sustain the garden.

🌱 The Children's Garden
Fun, impromptu activities are always available for the wee ones in our charming kids' area, and perhaps you'll find inspiration for things to do with the kids in your own garden. Even without a child in tow, it's a pleasant space to visit, vibrant with color and with cutie pie surprises tucked into every corner. This week, come through the gate and look to the right to ogle the bumper crop developing on the thornless blackberry garden.

🌱 The Free Produce Stand
Community generosity and local abundance provides for our table of free food items; the selection varies week to week based on what's thriving currently. This week, we'll have plums, potatoes, lettuce, and more. Coming soon: garlic! It's drying now, as seen below. And you never know when a kind soul will put out delectable baked goodies for us. You are invited to take home some freshly harvested yumminess—and feel free to bring your own surplus produce to share with your community.

🌱 The Free Community Pantry
Non-perishable food items are available to share. In these trying times, we would love to receive more non-perishable items to build up the pantry's stock. We appreciate your donations, which directly support local families. Thank you so much for your generosity!

🌱 The Free Seed Exchange
The seed table is always laden with choices for your planting pleasure. Pick up something new to work into your planting plan, or contribute seeds you no longer need to the collection. Master Gardeners will be available to help with your planting questions.

🌱 Pots needed for propagation
Do you have extra pots lying about? When you purchase a nursery plant, we'd love for you to save those original nursery pots for us. Master Gardeners at work in the propagation area are always in need of pots for the sale area. Standard nursery gallon-size pots are especially useful. Thank you to everyone who has helped us keep stocked up this year!

🌱 Monthly Garden Pest Management Checklist
Managing the health of our gardens while minimizing pest damage can sometimes seem overwhelming. Would you like some guidance? Check out the UC IPM's (University of California Integrated Pest Management) Seasonal Landscape IPM Checklist for timely actions to keep your garden in full health and those pesky invaders under control. From the linked page, you can review the current month's recommended strategies as well as sign up to automatically receive the list in a monthly email.

Before a UC Master Gardener can answer your gardening questions, they go through rigorous training backed by UC Agriculture & Natural Resources research.

What happens after that? They show up — at help desks, demonstration gardens, school programs, and community events across California — sharing what they've learned with anyone who needs it. For free.

Whether you're a gardener who needs help or someone who loves plants and wants to give back, the UC Master Gardener Program has a place for you.

Training times and locations vary by county. Find your local program: mg.ucanr.edu

Forget the gym. Gardening day hits different. 🌱💪

Hauling mulch = leg day. Pulling weeds = arm day. Bending over seedlings for an hour = back day (unfortunately).

Happy National Gardening Exercise Day to all the gardeners who are definitely getting their steps in.

It's California Invasive Species Action Week (June 6–14) — and your garden choices matter more than you might think.

Invasive species are non-native organisms that can spread quickly and negatively impact California's water, native plants and animals, agriculture, and local ecosystems. The good news? Home gardeners play a direct role in the solution.

Here's what you can do:
Avoid planting invasive species — choose native or non-invasive plants instead
Learn to identify invasive plants in your yard
Report invasive species sightings at wildlife.ca.gov/Conservation/Invasives/Report

UC ANR is a proud partner of California Invasive Species Action Week. Your local UC Master Gardener Program can help you choose the right plants for your county.

Find them at: mg.ucanr.edu

Greetings, Gardeners. The Calaveras County Master Gardeners Demo Garden will be open this THURSDAY for regular SUMMER hours from 9am to 1pm. Summer hours continue through October.

Many of us—and our plants—have enjoyed the coolish weather thus far; however, summer heat looks to arrive in earnest this week in the Foothills. These late spring months are a busy, colorful time at the Demo Garden. When you visit, you'll notice Master Gardeners working on this and that in all directions. You are welcome to ask questions—in fact, we encourage it. We're here to help with science-backed gardening information. Come to the garden and enjoy some fellowship with other gardeners, and bring your sunhat!

While you're strolling about, you may notice that some garden angels have been placing rocks painted bright yellow and lettered with "BUY ME" here and there. You'll see them at the base of notable plants that we currently have available in the plant sale area. Keep an eye out for those yellow markers...

🌱 The Plant Sale will be open
In the sale area, we have sweet potatoes, tomatoes, melons, and squash in limited quantities. Chives are also available in the Herb section to help flesh out your culinary plantings. We also have very nice variegated hostas (pictured below) in the shade plants area. Head back to the Trees and Edibles area in the westernmost corner of the garden for the full selection of herbs, grapes, artichokes, rhubarb, berry vines, figs, and more to build up your food forest.

We regularly stock dozens of kinds of plants for you to browse, including natives and drought-tolerant species, all locally sourced and propagated, as well as a wide and ever-changing variety of pots, planters, collectibles, and vintage items. The selections evolve rapidly; if you need help finding things, we are here to help; just ask!

All sales help sustain the garden.

🌱 The Children's Garden
This week, we will have Bugs in the Garden. Youngsters will be invited to catch and observe bugs using a magnifying glass, write down what they observe, and draw pictures of the critters. Good, crawly fun for the kids!

Fun, impromptu activities are always available for the wee ones in our charming kids' area, and perhaps you'll find inspiration for things to do with the kids in your own garden. Even without a child in tow, it's a pleasant space to visit, vibrant with color and with cute surprises tucked into every corner.

🌱 The Free Produce Stand
Community generosity and local abundance provides for our table of free food items; the selection varies week to week based on what's thriving currently. Lately, we've had green and red leaf lettuce and red cabbage available; rumor has it that sweet peas may also appear. And you never know when a kind soul will put out delectable baked goodies for us. You are invited to take home some freshly harvested yumminess—and feel free to bring your own surplus produce to share with your community.
