Fresh fruits and vegetables are essential to a healthful diet, but it's hard to keep perishable foods on hand if one doesn't have a refrigerator or a home. To enhance the health of homeless people, the CalFresh Healthy Living, UC Cooperative Extension team in Alameda County has partnered with the South County Homeless Project to grow fresh produce for people staying at the emergency housing in Hayward.
For the past seven years, CalFresh Healthy Living, UCCE Alameda has been delivering nutrition lessons to residents of the South County Homeless Project, part of Building Opportunities for Self Sufficiency. The classes include Rethink Your Drink, Food Safety, Making Every Dollar Count, Eat Healthy Be Active Community Workshops, and Fresh from the Garden.
The South County Homeless Project facility houses 24 people for up to a year. With the help of the CalFresh Healthy Living, UC Cooperative Extension team, its existing garden was refurbished and redesigned. The large outdoor garden behind the facility offers therapeutic gardening opportunities to residents and provides food for their meals.
"I love the garden and when the cook cooks the vegetables, they taste amazing,” said one resident. “I am thankful for this garden and for having the CalFresh Healthy Living team.”
At one time, South County Homeless Project's backyard featured a flower garden. After years of neglect, weeds overtook the garden.
In 2022, CalFresh Healthy Living, UCCE Alameda proposed getting residents involved in growing food by resurrecting the garden with edible plants.
“Not only could we continue to engage residents in nutrition education classes, but we could also work together to reinvigorate their neglected garden,” said MaxFairbee, nutrition educator withCalFresh Healthy Living team,UCCE Alameda.
More than 15 varieties of herbs and vegetables planted
Residents and staff set out to replace the weedy beds with a vegetable and herb garden.
“We worked with South County staff and residents on the design, clean up, planting, harvesting and ultimately incorporating food from the garden into the kitchen for residents to enjoy the fruits of their labor,” Fairbee said.
For gardening expertise and support, Fairbee enlisted the UC Master Gardeners of Alameda County's Community Garden Team to help. While the CalFresh Healthy Living, UCCE staff continued providing nutrition classes, the UC Master Gardener volunteers trained the residents on the basics of gardening.
In April, after heavy rains, the group planted 50 seedlings, half donated by the UC Master Gardeners. They planted two varieties of lettuce,arugula, four varieties of tomatoes, zucchini, kale, onions, cucumbers, green beans, Swiss chard, kale, basil, cilantro, tarragon, thyme, parsley, rosemary, oregano and mint.
From garden to table
“In May, we harvested lettuce and in June, we harvested green beans, cucumbers, kale and onions,” Fairbee said.
The fresh vegetables and herbs were used to prepare salads, sandwiches and pasta dishes for the residents. Fairbee and the other educators have also used the fresh produce for cooking demonstrations and tastings as part of their Fresh from the Garden class.
"We have been able to use many of the veggies as sides or to go in the salad," said one of the South County Homeless Project cooks.
"One of the chefs used the zucchini in the pasta sauce, it was so good! I didn't really know you could use it that way!" said a resident.
After tasting summer squash andgazpacho made with tomatoes from the garden, a South County resident namedSelina said, "I was surprised how good the raw summer squash tasted and how the flavor was different after it was cooked. I'll definitely be adding more zucchini to my plate."
Challenges to keeping the garden going
To keep the garden healthy, they faced competition with plant-chewing snails, slugs and aphids and cats digging in the soil. Because the water source is over 200 feet from the garden, they run a long hose across the main path, along the parking lot to water the plants, then unhook the hose and stash it indoors after each use so that it won't get stolen.
Another challenge of maintaining the garden is getting enough residents and staff to volunteer to work on it.
“Although staff are supportive of the garden, none actually have time to work in the garden,” Fairbee said.
The residents harvest, wash and store the produce in the kitchen. Only four to six of the 24 residents are typically interested in working in the garden, pulling weeds and protecting the plants from pests – most are focused on getting a new job and a home. South County residents usually leave the temporary housing within a few months.
For more consistent garden maintenance, Fairbee is looking to other community groups for volunteers. He is also hoping to persuade the county government to install a water spigot close to the garden so they can install drip irrigation to water the garden.
“We'd like to work with the UC Master Food Preservers to teach residents how to preserve herbs and vegetables,” Fairbee said.
He hopes South County Homeless Project residents will continue gardening in their new homes to grow fresh vegetables so they can enjoy a more nutritious diet and better health.
Beyond the fresh food, the South County Homeless Project residents and staff enjoy the ambience of the garden.
"It's really nice to go back there and just sit, it's really peaceful," said one staff member.
A resident added, "(The garden) relaxes me from stress. I love the garden."
Spring is here and if you are like us, you can't wait to get outside and see how your plants and garden are doing! As usual, UC IPM has useful tips for the month of April to prevent pests in the garden and landscape. To see more tips specific to your region, visit the Seasonal Landscape IPM Checklist on the UC IPM website. Here are some general tips to get you started:
- Cover fruit trees with netting to exclude birds and other vertebrate pests.
- Aphids are out already so look for them and their natural enemies such as predaceous bugs like lacewings, lady beetles, and syrphid flies. On sturdy plants, spray aphids off with a strong stream of water or apply insecticidal oils or insecticidal soaps to kill them.
- Manage ants. Plants infested with honeydew producing insects like aphids, whiteflies, and mealybugs may attract ants who take that honeydew back to the nest to feed the colony. Manage ants around landscape and building foundations using insecticide baits and trunk barriers.
- Whitewash tree trunks to deter borers and prevent sunburn. Apply to young trees or older bark on susceptible trees newly exposed to sunlight.
- Look for signs of clearwing moths boring in ash, birch, pine, poplar, and willow.
- Check for signs of powdery mildew on apple, crape myrtle, grape, rose, and stone fruits. Take preventative measures, like pruning, to provide better air circulation between plants.
- Watch for yellowjackets and other wasps building nests in undesirable locations. Knock down newly started nests and use lure or water traps to control populations.
- Prevent mosquitoes by eliminating standing water in gutters, drain pipes, flowerpots, etc. Place Bt “dunks” (Bacillus thuringiensis subspecies israelensis) in birdbaths and ponds to selectively kill mosquito larvae.
- Adjust watering practices as rainfall decreases. Check irrigation systems for leaks and broken emitters and perform maintenance as needed. Consider upgrading the irrigation system to improve its water efficiency.
- Monitor stone fruit trees for pests such as aphids, borers, brown rot, caterpillars, powdery mildew, and scale insects.

After all the winter rains you may find yourself dealing with weeds and struggling to control them. The first step in successfully controlling weeds is knowing what weed you have. Well, you're in luck: the UC IPM website contains many useful resources to help you identify and manage weeds in the garden or landscape.
A great place to start is the Weed Gallery, which contains images and identification tips for more than 150 common weeds.
If you think you know the name of your weed, you can use the common or scientific name to view photos to confirm identification. Just use the “List of All Weeds” link from the main weed gallery page.
If you don't know what the weed is, the gallery will help you identify the plant using visual characteristics. First, narrow your search by choosing “identification” in the weed category—broadleaf, grass, sedge, or aquatic plant. That will show you a collection of photos in that category.
Select the photo of the plant form or leaf characteristic that resembles your weed (Figure 1) to see another sub-menu of weeds that exhibit more traits of your weed. Scrolling over a thumbnail image on this sub-menu will bring up several photos of the weed—as a seedling and mature plant, its flower, and seeds—to further help you identify it.
Once you think you've identified the weed, click on the linked weed name, which will take you to a photo gallery page. Here you will find details about the weed's habitat, growth characteristics, and life stages. For many weeds, there is a link to the Pest Notes that will give you information about its management, both chemical and nonchemical. Each page in the gallery also links to the Calflora website to show where the weed grows in California.
The gallery contains other features as well:
- Want to know more about plants and their parts? Illustrated tutorials distinguish among broadleaf, grass, and sedge plants and define plant parts used in characterizing certain plant species.
- Need to find out what weeds are in your lawns? The broadleaf and grass categories link to an identification key for common turf weeds.
- Didn't find your weed? See the weed identification tool under “More information” to search the UC Weed Research & Information Center (WRIC) technical weed key.
You can find the weed gallery page on the left-hand column of the main Home & Landscape page on the UC IPM web site or from the many weed-related pages. To access the weed gallery directly, visit https://ipm.ucanr.edu/PMG/weeds_intro.html.

Follow these general tips for the month of March to prevent pests in the garden and landscape. To view more tips specific to your region, visit the Seasonal Landscape IPM Checklist on the UC IPM website.
- Look for aphids and their natural enemies such as predaceous bugs, lacewings, lady beetles, and syrphid flies. On small plants, spray a strong stream of water or apply insecticidal oils or insecticidal soaps to kill them.
- Fertilize caneberries, citrus, deciduous fruit trees, palms, and heavily-flowering shrubs with slow-release products.
- Monitor for the crawler stage of scale insects and apply horticultural oil if scales are abundant.
- Remove weeds as soon as they pop up in the garden or landscape.
- Apply organic mulches where thin or soil is bare under trees and shrubs to prevent weeds and regulate soil moisture and temperature. Keep mulch back from trunks and at a depth of 2 to 4 inches, depending on the mulch type.
- Prevent mosquitoes by eliminating standing water in gutters, drain pipes, flowerpots, etc. Place Bacillus thuringiensis subspecies israelensis in birdbaths and ponds to selectively kill mosquito larvae.
- If olive psyllid was a problem in past years, use an appropriate insecticide when the first generation of psyllids appear.
- Whitewash tree trunks to deter borers and prevent sunburn. Apply to young trees or older bark on susceptible trees newly exposed to sunlight.
- Keep an eye out for codling moth adults on apple and pear. Bag fruit and promptly remove infested or dropped fruit.
- Apply blossom sprays to prevent new fire blight infections. Look for oozing and dead limbs on pome plants such as apple, crabapple, pear, and pyracantha as soon as spring growth begins.
- Check for signs of powdery mildew on apple, crape myrtle, grape, rose, and stone fruits. Take preventative measures, like pruning, to provide better air circulation between plants.

In February we recognize Valentine's Day, President's Day, and Black History Month, but did you know it is also IPM month?! Join us in celebrating by learning more about integrated pest management (IPM), how you can use it in your everyday life, and the pest management resources and information offered by UC IPM.
What is IPM?
Integrated pest management (IPM) is a more sustainable, environmentally friendly method for managing pests like insects, diseases, weeds, and unwanted wildlife. IPM can be used by anyone: homeowners, tenants, farmers, gardeners, janitors, groundskeepers, professional landscapers and pest control operators, and more.
IPM focuses on the long-term management of pests through prevention and monitoring. This reduces pests reaching damaging levels and becoming difficult to control or requiring pesticide use. One way pests can be prevented outdoors is by providing plants with proper care (water, sunlight, and nutrients). You can prevent pests from coming indoors by sealing gaps around windows and doors. Monitor for pests using tools like sticky traps, or visual inspection.
Once a pest becomes a problem, it must be correctly identified so the correct management solution can be chosen. Many pests can be managed without the use of pesticides. In IPM, we often choose nonchemical solutions first:
- Biological control: the use of natural enemies—predators, parasites, pathogens, and competitors—to controlpests and their damage. Some examples of natural enemies include ladybeetles, lacewings, and spiders.
- Cultural control: practices that limit pests from establishing, reproducing, and living where they're not wanted. These practices can include increased cleanliness, proper storage of food, good plant care, and well-maintained landscape irrigation systems.
- Mechanical or physical control: kill a pest directly, block pests out, or make the environment unsuitable for them. Examples include traps for rodents, mulches for weed management, and flyswatters for flying insects.
Pesticides can still be an important part of IPM, but they should be used in combination with nonchemical solutions for long-term management. Pesticides alone will not solve a pest problem or prevent pests from becoming a problem again later. When pesticides are needed, choose products that are less toxic. Less toxic pesticides are those that pose fewer risks to people, pets, the environment, and natural enemies like ladybeetles. Learn more about less toxic pesticides at https://ipm.ucanr.edu/QT/lesstoxicinsecticidescard.html.
Whether you are trying to control cockroaches in an apartment, weeds in the garden, or diseases on landscape plants, UC IPM has the tools and resources to help you using an IPM approach.
