I've spoken with countless gardeners over the years who wish to start their own bee haven. That's great -- the bees need all the help we can give them. But the most misunderstood part of the process is how much preparation needs to take place before a single plant goes in the ground.
As the Haven winds down, I'd like to share some tips on preparing to install your own bee garden.
Many gardeners are removing a turf lawn to create their bee haven. It's important to take the time to do this correctly so your garden doesn't revert to a weedy mess. UC IPM has great information about turf removal, including how to identify your turf species (knowing your species helps with removal) and how to remove existing turf.
If you are opposed to using herbicides to kill your lawn, solarization can also be used. For most lawns it will take longer and be less effective. That is definitely the case for bermudagrass lawns that are common in California. Figure 1 summarizes the pros and cons of various turf removal methods. For more own bermudagrass lawn, I used a combination of herbicides, sheet mulching, and hand removal.
Finally, weed barrier fabric is never recommended. It prevents ground-nesting bees from accessing the soil, traps weed seeds that grow through the fabric and become impossible to remove, and breaks down over time to leach microplastics into the ground.
Whatever methods you use, patience is key. Plan on at least one year of preparation before planting.
It's also essential to know your soil type and its physical characteristics. Jar tests and drainage tests provide important information about how your soil will hold water. In California, the UC Davis Soil Web has detailed soil maps; these may be less accurate if you are in a new development where there has been recent soil disturbance or addition of new topsoil.
Finally, watch the pattern of sun and shade in your garden for a year before planting. Many winter-blooming 'full sun' plants will do fine under deciduous trees as they are in full sun when flower buds are forming. In the hotter part of California, some 'full sun' plants may need shade in afternoon.
The final task while you're in the process of killing your lawn is to learn about and choose plants for your garden. Garden tours are a great way to start this process....you'll see what grows in your area and have the chance to speak to other gardeners. These are often sponsored by municipal water authorities. Botanic gardens and independent garden centers with knowledgeable staff are other great resources.
The UC Master Gardener program has trained volunteers throughout the state to provide research-based gardening information. They are a fantastic resource and hold educational programs like this one for the public. Finally, garden clubs and the California Native Plant Society hold tours, plant sales, and educational events.

May is here and with all the fluctuations in our weather lately, there is a lot going on in the landscape! Follow these general tips for the month of May to prevent pests. To see more tips specific to your region, visit the Seasonal Landscape IPM Checklist on the UC IPM website.
- Look for the invasive Asian citrus psyllid on new citrus growth. If not known to occur in your area, report findings to your local county agricultural commissioner.
- Prune winter-flowering shrubs like camellia before next year's flower buds form.
- Check plants for leaf stippling or webbing from spider mites. Irrigate adequately, mist leaf undersides daily, reduce dustiness, or spray horticultural oil to manage them.
- Monitor for grape diseases like powdery mildew, Eutypa dieback, Phomopsis cane and leaf spot, and others. Prune, remove, or treat as appropriate.
- Cover fruit trees with netting to exclude birds and other vertebrate pests.
- 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.
- Fertilize caneberries, citrus, deciduous fruit trees, palms, and heavily-flowering shrubs with a slow-release product if not done in March or April.
- Monitor stone fruit trees for pests such as aphids, borers, brown rot, caterpillars, powdery mildew, and scale insects.
- 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.

The best time to plant a tree was 20 years ago. The second-best time is now.

What is your happiest memory that involves trees? Hopefully, most of those memories are positive. Trees provide a multitude of benefits that are hard to overlook. Reflecting on happy memories involving trees often evokes a sense of joy and wonder. These towering guardians not only serve as the backdrop to cherished moments but also provide an array of invaluable benefits.
However, in regions like the Western United States, escalating wildfire risks loom large, burdening homeowners with soaring insurance costs and stringent fuel reduction mandates. Balancing the delicate interface between natural landscapes and urban expansion becomes increasingly intricate, especially when community priorities diverge. As residential areas extend into undeveloped territories, trees, whether vibrant or ailing, transition from assets to potential hazards, underscoring humanity's profound dependence on their presence despite the associated challenges.
Trees are essential components of our daily lives, providing a multitude of human health benefits that we often take for granted. Regardless of whether they thrive in lush forests or line bustling urban boulevards, trees also offer a plethora of environmental advantages. Currently, forest ecosystems are the largest land-based carbon sink on earth. Forests in the U.S. alone offset about 16 percent of annual greenhouse gas emissions. Ninety percent of Americans support tree planting as a climate change mitigation measure.
Trees are also an essential component to ecological systems. They produce oxygen, sequester carbon, lower surface temperatures, control erosion, mitigate stormwater runoff, enhance habitat and biodiversity, contribute to urban cooling, provide food and fiber, promote social-emotional well-being, and perhaps most importantly, provide beauty to the landscape. Trees also boost property values and can even attract shoppers to urban centers.
Amidst a global population surge and escalating food demands, rampant deforestation threatens nearly half of our planet's forests. This perilous trend undermines crucial opportunities for carbon sequestration, allowing emissions from vehicles, industries, and other sources to persist unchecked. Moreover, the absence of verdant canopies in urban landscapes exacerbates the formation of heat islands, posing serious public health risks.
Deciding what tree to plant where can be challenge for some. Some (native) trees are not adapted to urban environments, while others may drop leaves, flowers, fruit, or branches, push up sidewalks, require frequent pruning, become invasive or have other undesirable characteristics. Municipal tree maintenance programs are costly and even controversial in some communities.
The Urban Forest Ecosystems Institute at Cal Poly is a tree information site with "features to assist in narrowing down site conditions, watering needs, and phenological characteristics. The “Select a Tree" feature assists users in choosing a tree with desired characteristics suited to a particular location.
I personally cannot imagine a life without them. As stewards of the environment, it's imperative that we recognize the indispensable role trees play in sustaining life and take concerted action to protect and nurture them for generations to come.

Water is essential for nurturing vibrant gardens and landscapes. By leveraging water meters, we can effectively monitor water usage, detect leaks, and optimize irrigation practices, ensuring every drop contributes to the sustainability and vitality of our gardens.
Understanding how to read a water meter is invaluable. It allows users to gauge water usage over time, detect leaks, and facilitates utility billing based on actual water consumption. Knowing how to read a water meter is great for tracking your yard's usage and spotting leaks.
How to Read a Water Meter
Most water meters are situated outside near the curb in a concrete box, marked with "water." Use a meter key or large screwdriver to remove the lid. Always check for spiders or other critters before reaching inside.
Understanding the Display
There are three types of water meters: straight-reading meters, digital-reading meters, and round-reading meters. Each type operates differently, displaying and indicating water usage differently.
-
Straight-Reading Meters: Have black numbers on a white background. Usually, for residential meters, one sweep of the face equals 10 gallons or 1 cubic foot of water. The black numbers with a white background reflect the current meter read either in 1,000 gallons or CCF (1 CCF=100 Cubic Feet).
-
Digital-Reading Meters: Display a flashing indicator when water flows. The display might alternate between the meter reading and the flow rate.
-
Round-Reading Meters: These are less common and feature several separate dials. Read each dial from left to right, noting the value indicated by each.
Calculating Usage
Take a reading and run your irrigation. After you're done, subtract the previous reading from the current one to determine the water usage within that specific period. For instance, if the previous reading was 3,000 gallons and the current reading is 3,500 gallons, the usage is 500 gallons.
Basic Leak Detection Using a Water Meter
Some meters have flow indicators, like a small triangle, star, or gear that moves when water flows through it. This can be useful in detecting leaks. Ensure no water is being used on the property: turn off faucets, fixtures, automatic appliances like ice machines, don't flush toilets, and turn off the irrigation system. Look at the low-flow indicator on the meter. Any movement might indicate a leak.
If your meter doesn't have a flow indicator, mark the position of the hand or record the numbers on the meter. Wait for a while, such as 30 minutes, without using any water. After that, recheck your meter. Any change in position or numbers indicates a potential leak.
Subtract the initial reading from the final reading taken after the waiting period to calculate the leak rate (gallons or cubic feet per minute).
Understanding how to accurately read a water meter and perform basic leak detection will make it easier to manage your water consumption efficiently and identify potential issues for timely repairs.
A colorful perennial has been brightening spring gardens for many weeks. Azaleas are the easy-to-care-for stars of semi-shaded locations. The most common varieties are evergreen azaleas, which are more accurately described as having “persistent-leaves.” They grow a set of spring leaves which are dropped in the fall, and a set of summer leaves which persist through the winter.
Azaleas are long-lived and can be used as permanent plantings, so consider the following factors before planting them in your yard.
Exposure: Azaleas prefer cool, partially-shaded sites, such as under under pine, oak or maple trees.
Mulch: A two- to three- inch layer of organic mulch (leaves, pine bark, wood chips) will conserve moisture and help discourage weeds. Extend the mulch a couple of inches from the main stem to keep the bark dry.
Watering: Azaleas are shallow-rooted. If possible, use soaker hoses or drip irrigation to slowly water the base of the plants. Overhead irrigation may promote disease.
Fertilizing: If planted properly, supplemental feeding is unnecessary.
Pruning: The best time to prune is in spring, just after the plant has finished blooming.
My existing plant didn't bloom, now what? --You may already have azaleas and are disappointed that they no longer bloom. You may need to give them more sun, perhaps by opening up the branches of the overhead trees, as well as pruning the azaleas to increase next year's buds.
Reasons for stingy flowering or lack of blooms include:
- The azaleas were allowed to dry out or to have wet feet. A two- to- three-inch- deep layer of mulch can help with water retention. Check the irrigation to make sure they are not being over-watered.
- Fertilizing with too much nitrogen may interfere with blooming. Did the plants receive fertilizer while you were feeding the grass?
- If you pruned after the flower buds developed, next year's flowers were inadvertently removed. Prune shortly after this year's flowers fade.
- Less than three hours of sun per day reduces the number of buds. Prune overhead trees, or consider moving the plant and its root ball to a better location.
