Filoli Gardens in May

What fun is must have been for the children raised in the 1900’s at Filoli Estate. You can just imagine what a kid could do on 654 acres of orchards, fields and gardens creating a maize of places to hide and seek. As gardeners a visit to Filoli Gardens will inspire you to re-imagine what your own garden can be. It’s spring. Here are some of my takeaways from my recent visit to Filoli.

Filoli Gardens is a manicured garden around the mansion and carriage house so the paths are straight and formal. Lined with dwarf boxwood each path encloses a different grouping of plants that change with the seasons. Many of us have meandering paths in our gardens separating the different garden rooms. The elements of garden design, like arrangement of paths, planting beds and open spaces, shape your garden. Your eye is drawn along a path through a garden. The plantings along the sides serve to frame but it’s the style of the path itself that enhances your experience in the garden. Some of the paths at Filoli Garden are gravel, some grass and some brick and mortar. All draw the visitor deeper into the garden to explore and linger at each spot.

Every month there is a different assortment of trees, shrubs, bulbs and vines blooming at Filoli. On this visit the wisteria took center stage. Their fragrance was intoxicating. To keep them in check volunteers keep them pruned tightly. Yes, it’s an ongoing task but the rewards are worth it. I’ll cover wisteria care in another column so you’ll know how to live in peace with your wisteria.

As in any garden, color plays an important role. It’s the wow factor we all go for. At Filoli on my recent visit the foxglove were in full bloom. I liked the apricot ones growing under the wisteria outside the carriage house. But then a bed of dark rose foxglove under another wisteria vine caught my eye. In my humble opinion, the combination could have been enhanced with some white flowers or silver foliage to tone it down but this bed was breathtaking. Everyone was photographing it and posing in front. Something to remember is that light colors like pale pink and blue, creamy yellow and lavender are more vivid in low light or on an overcast day.

Another show stopper was a vivid red azalea blooming throughout the gardens. Even from a long distance you couldn’t help but be drawn to them. Many were planted to be viewed against the dark green foliage of large shrubs and the mature columnar yews. As opposites on the color wheel, red and green are complementary and striking when paired together.

Some of the best beds still had some late blooming tulips. One of my favorite combinations was the softest pink parrot tulips with the purple allium pom pom flowers towering overhead. Another bed featured medium pink tulips, allium, white foxglove and the feathery burgundy foliage of fennel. A nice combination indeed and one you wouldn’t think of normally.

A huge Beni Hoshi flowering cherry was in full bloom with soft pink rhododendrons below. There are so many varieties of rhododendrons that you can have them blooming from March until May. They are long-lived and deer resistant.

Like kids in a candy store, my fellow companions, who are both Master Gardeners, enjoyed every turn at Filoli Gardens. We plan to go back in a couple months for the next rotation of flowering trees, roses and perennials.

Growing Veggies in Shade, Containers & Small Spaces

I have been gardening for a very long time. But even now I feel I know just a little bit about a whole lot of subjects. Every day I learn something new. Now that spring weather has finally arrived I’m anxious to start planting like the rest of you. Because I have a lot of shade that rotates during the day and a small space to garden I am limited by what I can grow successfully. On a lark I signed up for a free ChatGPT Open AI account to see what all the fuss was about and whether I could learn anything from my query. Let’s just say the results were a little dry. So here are my own thoughts about growing vegetables in containers, small spaces ors shade.

The best veggie varieties for growing in containers are: beans, chard, chili peppers, kale, lettuce, onions, radishes, spinach, sweet peppers and tomatoes. Last year I grew some French Marcotte container bush beans which were delicious although I ended up nibbling on them raw while putzing around on the deck. They were delicious. Strawberries are great for containers, too.

Little Crunch Snap Pea

Last week I started some Little Crunch Container Snap Peas. The package says I’m to get loads of crispy, sweet pods on vigorous short vines that are perfect for snacks. Peppers, both chili and sweet varieties do well in containers, too. You might want to try growing bite-sized sweet peppers for your pizza or for snacking while out in the garden.

Tomatoes are always popular to grow whether in the ground in a small garden or in pots on the patio. Bush types (determinate) don’t grow as large as indeterminate vines. If you like large size tomatoes, plant Bush Beefsteak and you’ll be harvesting clusters of delicious 8 ounce. tomatoes in just 62 days. A half wine barrel can house a taller tomato like the ever popular Sungold. Small gold-orange cherry tomatoes ripen early and are oh-so-sweet. You’ll plant these every year after you’ve tasted one.

Zucchini lovers might try the non-rambling Raven or Astia varieties which won’t take up as much space as a traditional type. If you have a little space to spare grow the round French heirloom squash, Ronde de Nice. Jade colored zucchini produce over a long period. Harvest the fruit when they reach golf ball up to baseball size. They are sublime grilled or try them stuffed. A tip to encourage pollination when squash or melons bloom is to pinch off leaves covering the blossoms in order to give pollinators a clear path to the flowers.

Herbs make good additions to the smaller garden, too. They can be kept compact with frequent pinching as you harvest sprigs for cooking. They also attract beneficial insects to the garden. Oregano, chamomile and fennel are good insectary herbs.

Shade tolerant vegetables for your brightest spots – the partial shade areas – include beans, peas, potatoes, pumpkin, summer squash and early maturing tomatoes like Early Girl, Stupice, San Francisco Fog, Isis Candy as well as other cherry tomatoes. Corn and peppers will be lankier and bear later and only modesty in partial shade.

Root crops and leafy plants can tolerate more shade than fruiting crops. Beets, carrots, potatoes, celery and turnip will grow quite happily in partial shade. So will shallots and bunching onions, cilantro, garlic, chives, kale, leeks, parsley, oregano, cilantro and thyme. Leafy plants can tolerate partial to light shade because their leaves grow larger to absorb the sunlight the plants need. In very light shade areas concentrate on leafy green like Swiss chard, lettuce, spinach, arugula, radishes and tarragon.

Shade can be decidedly helpful to some crops. Leafy greens will be more tender and succulent, without the bitterness they tend to acquire when conditions are too hot. A combination of a bit of afternoon shade and an abundance of moisture will help cut-and-come-again crops like broccoli, lettuce, cabbage and celery stay in good condition longer in hot weather.

Whatever plants you grow in your shady garden, be sure not to crowd them. Plants tend to sprawl there and if placed too close together they will compete for available light. Place your vegetables plants wherever they will get the most light even if it means putting different crops in separate places. A small harvest is still better than no harvest at all. Your vegetables may take a bit longer to mature without full sun so be patient.

Growing Dogwoods

When the dogwoods start to bloom I”m torn between the flowering crabapples and cherries and wisteria and lilacs. But those huge dogwood flowers – or more precisely, bracts – get my attention every time I drive along the thoroughfares of San Lorenzo and Scotts Valley. Most of us are familiar with the common Eastern dogwood but there are so many more great cultivars available now. Here’s some information you’ll find useful if you’re in the market for dogwood tree and how to care for them if you already are lucky enough to have one in your garden.

There are four main species of dogwood trees. From the Himalayas in China comes cornus capitata. Korea is home to cornus kousa. Cornus florida is native to the east coast and the west coast is home to cornus nuttallii or the Western dogwood.

Our native Western dogwood is unfortunately prone to leaf spot fungal diseases when grown out of their range. They are a little temperamental in the garden before they reach the age of 10 years but after that they tolerate seasonal flooding and flower and grow with little care in morning sun or light shade.

We are all familiar with the Eastern dogwood (cornus florida) that’s blooming now. With various shades of pink, red or white blossoms they are stunning. Take note that their root system is prone to disease if not grown with good drainage.

An awesome variety ‘Pringlei’ or Mexican Flowering Dogwood is grown by a fellow gardener and it’s a stunner. With its unusual flowers than look like Chinese lanterns to the red fall color this is a species to be on the look out for.

The Wedding Cake Tree (cornus controversa ‘Variegata’ ) is another unique variety. When this small dogwood blooms the large flowers cover the tree like snow. The tiered horizontal branches resemble a wedding cake when in bloom.

The kousa dogwood is a more drought tolerant, disease resistant and a tougher plant all around. Large, showy flowers open after the tree has leafed out and remain for a long time. This makes it good for hybridizing with other varieties.

The Stella series is a mix of a florida on kousa dogwood rootstock. Vesuvius series is a cross of our native nuttallii with a florida as is Eddie’s White Wonder. There is also a nuttallii-kousa cross called Venus that displays huge flowers and gets its disease resistance from the kousa roots. All these cultivars strive to produce a tree with superior disease resistance and huge, long lasting blooms.

Deciduous dogwoods don’t like wet feet especially in the winter. That’s how they develop fungal disease. But there’s an evergreen dogwood that can handle moisture all year round. Cornus capitata ‘Mountain Moon’ is a tough tree that can handle strong winds and isn’t bothered by any pests or diseases. They enjoy lots of organic matter as do all dogwoods. Huge flowers up to 6” wide can last from late spring into early summer. After flowering, the fruits begin to form and grow into red balls about the size of large strawberries. This is the reason is it also known as the Himalayan Strawberry Tree.

Dogwoods attract a variety of wildlife. All sorts of critters use this tree for food and shelter. The giant silk moth and several species of butterflies favor dogwoods as host plants. The spring flowers provide nectar to bees and other pollinating insects. Robin and sparrow are just two of the bird species that build nests on the horizontal branches and many others seek shelter in the leaves. The high calcium, high fat, fleshy red fruits are eaten by 35 species of birds including titmice, juncos and waxwings.

Many people think of dogwoods as an understory tree but this location is often too shady. Grow them in a full or partial sun location that gets afternoon shade after 4:00 PM. Add a couple of extra drip emitters or inline drip tubing to your irrigation system and they’ll be happy.

Dogwood are a good tree choice for the allergy sufferer as their pollen is not wind borne. Their showy flowers, which are actually bracts, are pollinated by insects. Their pollen is large and heavy, sticking to insects rather than becoming airborne and leading to sneezing, runny noses and watery eyes.

Earth Day Facts to Ponder

This year Earth Day is focusing on climate change. Earth Day is always a celebration of the natural beauty of our planet reminding us that we need to keep it healthy. Always on April 22nd, Earth Day is a day of education about environmental issues. So plant a tree, clean up litter, garden, hike in the woods, marvel at emerging wildflowers, be in contact with the soil and breathe fresh air outside on this day.

The affects of climate change have been front and center for us here in the Santa Cruz Mountains. Few of us anticipated that we would have storm after storm hit us – 31 atmospheric river storms starting last December. The intensity and duration of these storms caused record snowfall and deadly flooding. According to UCLA climate scientist, Daniel Swain, there isn’t a clear cut answer as to what caused the wet weather. “It could be anything from Hunga-Tonga volcanic eruption last spring which injected a record breaking amount of water vapor into the stratosphere…it could be an unusual transition from La Niña to El Niño.. it could be bad luck.” Whatever the reason, the effects of climate change are here to stay.

Celebrate Earth Day in your own backyard by being outside. It’s your own personal outdoor living room – a safe place for pets and kids to play. Just get outside, maybe trim some shrubs, plant something for the birds and pollinators. When you become a steward of your own yard, you are helping to preserve you own corner of the ecosystem. Our connection to the earth is one of the most valuable lessons we can share with our children.

In a garden, children can breathe fresh air, discover bugs and watch things grow. And, of course, a garden offers kids and everyone else fresh, tasty homegrown food. What better place for kids to play than in a place where they can use their hands and connect with the earth? Where else can they make a plan for a plot of land and learn the lessons of hope and wonder, suspense and patience and even success and failure? In a garden you can have conversations about life and even death in a way that doesn’t seem so sad.

Finding things to do in the garden is easy. You probably already have some edible flowers in your garden. Tuberous begonia petals taste like lemon. Calendulas are spicy as are carnations and marigolds. Dianthus are clove-flavored, nasturtiums give a hint of horseradish and violas, pansies, hollyhock, squash blossoms and johnny-jump-ups taste like mild lettuce. You can also freeze flowers like violas, fuchsias, geranium, stock and thyme in ice cubes.

Flowers that kids can cut will be interesting for them, too, especially when planted in their own garden. Cosmos, planted from six packs, provide instant color as well as attracting butterflies. Zinnias come in a rainbow of colors and are a favorite of swallowtail butterflies. Another easy to grow flower for cutting is the snapdragon.

Besides flowers, fragrant foliage plants like lemon basil, lemon verbena, lime thyme, orange mint and other herbs engage the senses and can be included in a kid’s garden.

Pet-able plants are a sure hit with kids. Usually we tell them, “Don’t touch”, so to actually have someone encourage this is a rare treat. If your own garden doesn’t have plants that look and feel so soft that you can’t resist petting them, consider adding lamb’s ears which are soft and furry, artemisia ‘Powis Castle’ or fountain grass.

All kids love lady bugs. Make your garden a more inviting place for these and other beneficial insects by planting lots of flowers and herbs to attract them. Lady bugs will patrol your plants looking for tiny insects and their eggs. Flowers with umbrella shaped clusters of small flowers such as cosmos, zinnia, black-eyed Susan and yarrow are favorites of butterflies.

Kid friendly gardens should not contain plants that are poisonous. Sounds like a no-brainer but even some of our common natives like the berries of snowberry and the leaves of Western azalea are poisonous. Non-toxic plants include abelia, abutilon, liriope, butterfly bush, Hens and Chicks, columbine, coneflowers, coreopsis and black-eyed Susan. Better to check the poison control website if in doubt. http://www.calpoison.org and search “plants”.

To share one’s excitement and knowledge of the outdoor world with a child is fun and rewarding. The wonder on a young person’s face as they discover a swallowtail butterfly, a flower just starting to open or a bird feeding in the garden is priceless. And be sure to leave some time after a busy day out in the garden for kids to draw what they’ve enjoyed outside.

Get a kid into gardening and nature and they’ll be good stewards of the land for a lifetime. Plus you’ll have a lot of fun in the process.

How to Attract More Bees to Your Garden

I’ve been worried about the bees lately. Can’t be easy being a bee given the severe weather we’ve had this winter. They’ve also had to deal with habitat loss, pesticides, climate change, pests like mites and pathogens such as viruses, bacteria and fungi. What can I do to help bees?

There are 1600 species of native bees in Santa Cruz county. They are solely responsible for pollinating many of our native plants. Being solitary they do not make a hive but make nests underground or live in wood, one female per nesting hole and she lays her eggs there. Leaving areas in your garden near flowering plants un-mulched helps her find a nesting hole. The hard working females mate, make nests, collect pollen for their young and lay eggs. Males live to mate and only pollinate inadvertently when they visit flowers for nectar to fuel their flight.

Common native bees in our area are the yellow-faced bumble bee and the long-horned bee which has stripes a little like a yellow jacket. The hard working bumble bee is easy to identify from its bight yellow facial hair and yellow bands on their backs and abdomens. Female bumble bees’ hind legs widen to form pollen baskets often filled with bright yellow, moistened pollen pellets.

The Long-horned native bee gets their name from the long antennae of the males although the females do not have this. Males may be seen by day jostling for female attention above a patch of blooming plants while the females are collecting pollen. Only the females have branched hairs on their legs for carrying pollen.

Bees eat two things: nectar which is loaded with sugar and is their main source of energy and pollen which provides proteins and fats. Some of the common native plants that are recommended for our area to attract bees of all types include yarrow, columbine, California poppy, coral bells, silver lupine, penstemon, ceanothus, toyon, big leaf maple, mahonia, monkey flower, buckwheat, western azalea and purple sage.

Common garden plants that can attract bees and provide pollen in your landscape and vegetable garden are herbs such as African blue basil, bee balm, oregano, mint, catnip and cat mint, borage, rosemary, chives, hyssop, dill, comfrey and fennel. Edibles that attract bees are blueberry, pumpkin, squash, sunflower, blackberry, hazelnut, artichoke, beans, cucumber and peas. Crabapple, iris, lavender, salvia, aster, coreopsis, sunflowers, monarda, aster, butterfly bush, sweet alyssum, alstroemeria, red hot poker, gloriosa daisy, verbena, scabiosa, coneflower and echium also attract bees of all types.

The higher temperatures that come with climate change can affect a bee’s ability to detect a flower’s pollen. A flowers scent is what tells a bee that nectar is present. If the weather gets too hot the plant will spend less energy on producing fragrance and just try to survive. When flowers stop emanating these enticing smells, some bees have a tough time finding food and may abandon certain area. Studies have shown that warming climates already have affected our central coast bumblebee population during the past 30 years especially the California bumblebee.

In your own garden an abundant and healthy population of pollinators can improve fruit set, quality and size. Crops raised in California depend on both domestic honeybees and native bees for pollination of almond, blackberry, cucumber and artichoke crops.

Honeybees and native bees need help to survive and we’re the ones to give it. Besides planting nectar and pollen sources you can help by buying local honey which support beekeepers. Use only organic pesticides and avoid applying during mid-day hours when honey bees and pollinators are most likely to be out foraging for nectar and pollen on flowering plants and only then if you can’t control a pest with any other methods including Pest Management techniques.

Help save the bees.

Forest Bathing in the Santa Cruz Mountains

Most of us around here either live in a forest or near one. We are no strangers to nature as some city dwellers might be. We often spend time on a trail. You know the feeling you get when you are out walking slowly in the forest, stopping to admire a wildflower or mushroom that catches your eye? You know it’s good for the mind and body, but why? It turns out that there are more benefits to being out in nature than the calmness it brings.

In the past several decades there have been many scientific studies that demonstrate the mechanisms behind the healing effects of simply being in natural areas. Many of the benefits from the forest actually come from the air. Trees give off phytoncides, such as alpha-pinene and d-limonene, which are volatile organic compounds or aerosols. These compounds protect the trees and plants from insects and disease, but they also benefit us.

Forest bathing is what the Japanese call it. Shinrin-yoku is their term that means “taking in the forest atmosphere.” Forest therapy has roots in many cultures throughout history. John Muir wrote that “Wilderness is a necessity.” Scientists is Japan are measuring what’s actually happening to our cells and neurons.

Trees give off organic compounds that support our immune systems and help our system fight cancer. Other scientifically proven benefits of forest bathing include reducing blood pressure, accelerating recovery from surgery or illness, improving sleep and our mood and reducing stress. Also being around trees can help alleviate anxiety and depression.

Forest bathing lowers our heart rate and lowers levels of the stress hormone cortisol. Soaking in the forest air increases our NK or natural killer cells by about 50 percent. One study in Finland found that spending time in nature cut the odds of using blood pressure medications down by 36 percent. And that’s pretty good.

Other studies have found that something about being in the nature is good for our brains. One study published last year by BioMed Central, a peer reviewed journal sharing research, found that older Americans living in regions with lots of greenery had lower rates of dementia. Another study from the National Library of Medicine found that cognitive decline slowed over a 10-year period for people living in lush spaces.

All I know is that when I am out in the garden or strolling in the forest I feel good. I stop to watch the progress of a banana slug. I listen for new bird calls. And as a garden designer I strive to create a space for clients that brings that feeling to them whenever they are outside.

And part of of that good feeling we get from being outside has to do with the color green. Green is the color of spring, of growth, renewal and rebirth. It renews and restores depleted energy. It’s a positive color and increases our feelings of relaxation and calmness.

If you don’t have a forest of your own bring that forest feeling to your own garden. Stroll in a relaxed way without thinking about weeds or pruning or other items on your to-do list. It’s relaxing, calming, rejuvenating and restorative.
