A Chemical-Free Garden for Monarchs

Posted on by under Nature

Is it possible to have a beautiful garden without using pesticides and herbicides? In my experience, it has been easy to have a healthy garden that doesn’t require chemical pest control.

Reducing our reliance on chemicals protects butterflies, and invites wildlife to step in and manage the unwanted insect population.

Birds feed their offspring mostly insects and caterpillars because insects are easy to digest when the baby birds are young and vulnerable. One nest of baby birds need more than 5,000 caterpillars to develop and be ready to fledge.

Adult birds, including hummingbirds, also rely on insects for protein and calories.

The images below show a kingbird after it captured a potato bug. The kingbird flew with the insect to a nearby elderberry bush and proceeded to smack the insect against a branch before eating it.

If you had killed the potato bug, the kingbird would have gone hungry. Sterilizing the outdoors with chemicals may be part of the reason terrestrial birds in the United States have declined by 3 billion birds since the 1970.

Instead of using pesticides, you can let birds and beneficial insects like the praying mantis shown below, do the work for you.

Although birds and beneficial insects help with pest control, some pests are better managed by the gardener.

I remove tiny orange aphids that are attracted to native narrow-leaf milkweed by squishing them with my fingers. First I make sure there aren’t any pearly monarch eggs nearby. The aphids are soft, and removing them takes about 10 seconds.

I recently heard an entomologist say adult monarch butterflies won’t lay their eggs on milkweed that has aphids, so I keep an eye on my milkweed plants and make sure to smash the aphids when they appear.

Before reaching for a pesticide, remember the possible harm chemicals can do to birds, butterflies, and bees. When you preserve the web of life in your garden, you will have fewer pests naturally, and a thriving butterfly population too.

Monarchs Arrive for Summer

Posted on by under Nature

Have you noticed monarch butterflies flying around your California yard this summer?

Western monarch butterflies are an iconic butterflies that delight us with bright orange plumage, black stripes, and white polka dots. They are so large, they cast a shadow when they fly overhead.

After hearing about the historically low overwintering monarch butterfly count last winter, I have been surprised to see a healthy number of western monarchs making daily visits to my home landscape over the past few months.

I am seeing more monarchs than I expected because last winter, fewer than 2,000 monarchs were counted overwintering in California. 

According to Xerces.org, “Early count numbers from Xerces’ Western Monarch Thanksgiving Count suggest that the western migratory population is headed for an all-time low. With approximately 95 percent of the data in, only 1,800 monarchs have been reported…This is a significant decline from the low numbers of the last two years where the total hovered just under 30,000 monarchs. These numbers are a tiny fraction of the millions of monarchs that likely visited overwintering sites in the 1980s and the hundreds of thousands of monarchs that graced California’s coast as recently as the mid-2010s. In fact, this represents an overall decline of more than 99.9% in the migratory population.”

What can we do to help reverse their dramatic decline in numbers?

Monarch caterpillars only feed on milkweed. The first step you can take to help the western monarch butterfly is to plant milkweed that is native to your area. Good native milkweed choices for Southern California include narrow-leaf milkweed (Asclepias fascicularis) and woolly-pod milkweed (Asclepias eriocarpa). 

You can install native milkweed plants now, and support monarch butterflies looking for a host plant to lay their eggs.

Planting milkweed that is native to where you live is more beneficial than non-native (tropical milkweed) because non-native milkweed often hosts parasites that harm butterflies and disrupts their reproduction and migration.  

One nursery in Southern California is trying to help increase western monarch populations by offering a free trade-in. At Roger’s Gardens in Corona del Mar, you can bring your non-native tropical milkweed into the nursery and receive a free native narrow-leaf milkweed replacement plant.

Another great nursery to buy native milkweed is Tree of Life Nursery in San Juan Capistrano. Tree of Life Nursery has several species of native milkweed plants for sale this year including woolly-pod milkweed shown above.

Planting plenty of native milkweed in your garden is a great first step in helping the western monarch butterfly populations recover. I will discuss more ways you can help monarchs in my next post. In the meantime, visit your local nursery and buy several milkweed plants for your garden, and while you are outside, look for monarchs cruising your garden.

Summer Buckwheat Blooms Bright

Posted on by under buckwheat

It is July, the height of summer in Southern California, and buckwheats are blooming with thousands of showy white flowers.

(E. Wallace)

I took a walk this morning at my favorite local park, O’Neill Regional Park in Trabuco Canyon. Many of the spring-blooming plants are hunkering down in the 90-degree heat, but California buckwheat (Eriogonum fasciculatum) is just beginning to shine. Look closely and you will see clouds of tiny butterflies and pollinators flying from blossom to blossom, gathering pollen.

Beetles too are enjoying the buckwheat blossoms.

(E. Wallace)

In the photo below, notice the tiny fly (upper left corner) coming in toward the buckwheat flower while the Flower Longhorn Beetle forages.

(E. Wallace)

If you are looking for a summer-blooming shrub for your garden, buckwheat should be one of your top choices. Buckwheats bloom for months during the hottest parts of the year and support clouds of pollinators, butterflies, and birds. Buckwheats are easy to grow, and once established, require no supplemental water.

(K. Ethington)

Try planting a buckwheat interspersed with salvias, fuchsias, and mallows. You will get year-round blossoms in your garden and year-round butterflies too. Add a native milkweed, such as narrow-leaf milkweed (Asclepias fascicularis), and support declining monarch butterfly populations.

(E. Wallace)

Native plants are gaining popularity as gardeners learn to appreciate their beauty and importance to wildlife. Join the movement! Try planting a buckwheat and see how many pollinators are attracted to your landscape. Then add more. Butterflies will flutter, birds will sing, and you will be filled with happiness.

My Interview with the LA Times

Posted on by under buckwheat, Nature

Jeanette Marantos, garden reporter for the LA Times, called me in mid-February as I was returning home from a landscape restoration project I work on in Trabuco Canyon.

(L to R) Brad Jenkins, president of OCCNPS, volunteer Vern Jones, Jeff Wallace and myself, after planting four Coast Live Oak trees and two toyons at a landscaping project in Trabuco Canyon. (E. Wallace)

Marantos asked me to provide a short list of the best native plants Southern Californians can plant in their home landscapes, and also why it is important to plant natives in the home garden.

We spoke on the phone for an hour and I suggested California native plants that are beautiful and easy-to-grow. We researched the plants together on the Calscape database. We also discussed Doug Tallamy’s research that shows when non-native ornamental plants are installed in the landscape, insect populations plummet because insects are co-evolved to feed from native plant species, not from introduced plant species.

Marantos’ article appeared in the LA Times on February 28 and is titled “Want to help bees and butterflies? Add these plants to your garden.”

Want to help bees and butterflies? Illustration by Julie Yellow for The Times.

Marantos wrote: “Once upon a time in Southern California, landscaping was primarily about decoration — the greenest lawn, easy-care sculptural shrubs and a few showstopper flowers, almost none native to the region or welcoming to butterflies or bees. In truth, we did everything we could to keep bugs out of our yards, and it worked — far too well.”

She spoke with Ron Vanderhoff, vice president of the Orange County Chapter of the California Native Plant Society (OCCNPS) and general manager of Roger’s Gardens nursery, who said, “Bees, butterflies and other native insects are dwindling because they’re running out of the habitat and food provided by native plants. If we want to save them — and the birds and other animals that need those insects to survive — we need to change how we think about landscaping.”

“There’s been a mind change where gardening is not just decorating, it’s doing something to help the world,” Vanderhoff said. “It’s gardening with a purpose to it.”

Kris Ethington, board member of OCCNPS, and winner of Orange County’s 2018 California Friendly Garden contest for re-landscaping her entire yard with only native plants, discussed her favorite plants for the garden including oaks, lemonadeberry, toyon, and verbena de la mina.

Here is a list of California native plants that Ron, Kris and I consider must-haves in every garden as reported in the LA Times:

If you are going to add just one native plant to your yard, make it a California buckwheat. At OCCNPS, we believe this is such an important plant for the landscape that we gave away 1,500 starter buckwheat plants to Orange County homeowners in our A Buckwheat in Every Garden program.

Salvias and sages are pollinators’ favorite flowers. White sage is a sacred plant to Native Americans; it has silvery foliage and thrives in hot, dry locations. For shady locations, hummingbird sage spreads abundantly, blossoming with magenta-colored flowers in spring and summer. Vanderhoff also recommends the fragrant Cleveland sage which thrives in most parts of Southern California.

Narrow-leaf milkweed has white flowers and is the best milkweed for monarch butterflies in Southern California. Many nurseries sell the orange tropical milkweed, but tropical milkweed is not native to Southern California, and researchers have discovered that tropical milkweed hosts a protozoa that makes adult monarchs sickly and weak, according to Vanderhoff. For that reason, Vanderhoff’s nursery, Roger’s Gardens, only sells narrow-leaf milkweed.

Maritime ceanothus. (Kris Ethington)

Ceanothus, commonly known as the California lilac, is a gardener’s favorite. With its honey sweet scent and profuse violet blossoms, this is a must have for every garden. The ceanothus variety ‘Yankee Point’ spills down hillsides in shady inland gardens. ‘Ray Hartman‘ ceanothus is a small-tree-sized California lilac covered with deep violet blossoms in springtime.

California poppies and lupine wildflowers are easy-to-grow annuals with spectacular spring and summer flowers. Gardeners can sow the seeds of these flowers just before winter rains and provide abundant support for pollinators. You can purchase these seeds from Tree of Life Nursery and Theodore Payne Foundation.

Manzanitas are the superstars of California natives. If anything will turn people toward natives, it’s manzanitas. Manzanitas’ bell-shaped blossoms, structural characteristics, and rich red bark make this a garden standout. Two varieties of manzanitas are excellent choices for the first-time native gardener: Arctostaphylos ‘Sunset’ and ‘Howard McMinn.’

Join me at and other members of OCCNPS at The Dana Point Headlands Earth Day Celebration on April 25, and pick up a free California ‘Dana Point’ buckwheat plant. We care about your garden and the pollinators your garden can support with the right native plants. Join us and bring your questions. We are here to help.

Where Do Western Monarchs Spend the Spring?

Posted on by under buckwheat, Nature

Despite the fact that Western Monarch butterflies are universally loved, their numbers have plummeted in recent years.

Your photo will help scientists better understand Western Monarchs’ locations and activities in February, March, and April. When you share your springtime Monarch observations, you help conservation efforts for the butterfly.

In between reporting your spring Western Monarch sitings, plant more native plants in your garden, especially California buckwheat, salvias, manzanitas, narrow-leaf milkweed, and maybe a scrub oak tree!

Saying Good Bye to a Billion Birds

Posted on by under buckwheat

Did you know that in 2016, North America had more than a billion fewer breeding birds than 40 years ago?

What is contributing to the decline in bird populations? Scientist Doug Tallamy has discovered that when non-native ornamental plants are installed in the landscape, insect populations plummet because insects are co-evolved to feed from native plant species, not from introduced plant species.

Insects make up 96 percent of terrestrial birds’ food source.

We have 3,300 species of ornamental plants (from other areas of the world) introduced in the United States. These plants are cultivated and promoted by nurseries and home improvement centers because they are unusual, pretty, and easy to grow.

Introduced ornamental plants do not support abundant insect life, and without insects–humans, birds, and animals cannot survive. Other factors contributing to the reduction in bird populations include pesticide use, bird strikes on windows and plexiglass fencing, and feral cats. To learn more, you can read Tallamy’s research in the Proceedings of the National Academy of Sciences of the United States (PNAS).

Returning birdsong to the outdoors is one of the reasons why the Orange County California Native Plant Society is giving away one free ‘Dana Point’ buckwheat to Orange County homeowners. Buckwheat supports 15 species of butterflies and moths, not to mention all of the native bees and other insects that thrive with this plant in the landscape. Plant a California buckwheat today and help birds find enough to eat.

Growing Buckwheat in the Garden

Posted on by under buckwheat

When cooler winter temperatures arrive in Southern California, residents wear sweaters and scarves to stay cozy. Buckwheat changes in the winter too, as the creamy white flowers turn a reddish brown when the flowers go to seed.

Buckwheat Builds Soil

Posted on by under buckwheat

California buckwheat is an evergreen plant with small leaves that occasionally drop to the ground, forming a natural mulch. The fallen leaves enrich the soil around the plant and allow the plant to grow and spread in its own loamy mulch.

Birds, Bees and Buckwheat

Posted on by under buckwheat

The California Native Plant Society Orange County (OCCNPS) chapter created A Buckwheat in Every Garden to encourage homeowners to plant California native plants in their home landscape– which in turn supports and increases bird populations.

California buckwheat has a long, prolific flowering season that attracts tiny native California bees and butterflies. When I looked closely at my California buckwheat plants this summer, I was astonished to see thousands of tiny pollinators on my buckwheat flowers. These pollinators support my vegetable garden and fruit trees, and they support bird life as well.
