Rhododendrons in the Garden

Rhododendrons are one of spring’s show stoppers. Huge, rounded clusters of stunning blossoms in lavender, red, purple, white, pink and even yellow and gold clothe these shrubs with color. You can have flowers from February to late May by choosing different varieties. And rhododendrons are easy to grow if you give them what they need.

Rhododendrons like air in the root zone so amend your soil liberally with organic matter. 50-60% is not too much. If you garden in clay, just plant them in raised beds or berms 1-2 ft above the original soil level. Rhododendrons like moist soil so top dress around your plants with several inches of mulch over the root zone, making sure the stem is not get buried. Pine needles, oak leaves or wood chips are good choices. Never cultivate around the plants as this would injure the surface roots. Finally, most rhodies thrive in partial shade or morning sun. The hot afternoon sun that we get during the summer would burn even those varieties that tolerate some sun. Since their leaves remain on the plant for several years you’d have to live with burnt leaf centers and edges for a long time if they get too much sun.

Because rhododendrons contain toxic resins that are more concentrated in the foliage, weevils have developed a resistance to pesticides along with a tolerance for the toxins in the leaves. Organic or even chemical sprays have little effect anymore according to a study funded by the Rhododendron Society of America and end up killing hundreds more predatory beetles and other beneficial insects in the process.

Applying parasitic nematodes to your soil is one way to control weevils. Other tactics include placing a shallow pan of water under the plant or a soup can filled with soapy water buried up to the top to attract and drown the adults . You can also try banding the trunks with tape or waterproof paper and smearing the bands with a sticky barrier like Tanglefoot. Spreading some coffee grounds under the plants also helps to discourage them from crawling up the trunk after they spend the night at the base of the plant. And if you’re really determined you can hand pick them after dark- effective but not much fun.

Our native rhododendron occidentale

There are thousands of rhododendron varieties. By planting early, mid-season and late blooming types you can enjoy those huge, gorgeous flowers for months.

Cheer is one of the showy early bloomers. Large, pink flower trusses cover the 5×5 ft plant. It can take some sun and would be a good candidate if you have one of those gardens that receives and hour or so of afternoon sun.

For April blooms consider Edith Bosley. Similar to Purple Splendor it grows upright to 6 ft.tall but only 4 ft wide. Perfect for narrow spaces. Other mid-season bloomers that would make a splash in the garden include Golden Gate, a 3 ft compact orange hybrid and easy-to-grow, red-flowering Jean Marie de Montegue.

To extend your season add some late season varieties like Lee’s Dark Purple. Growing with a spreading habit to 4 x 5 ft wide, you’ll love its blue-purple trusses. Anah Kruschke also blooms late in spring with lavender pink flowers on a dense 5 x 5 ft shrub. A tough undemanding larger variety is English Roseum. This one grows 6 ft tall with lavender pink flower trusses and blooms in May.

Rhododendrons really contribute to the woodland or shade garden. They are long-lived and deer resistant. I’ve only heard two gardeners tell me that deer ate some of their flower buds last fall for the moisture content. Most likely those deer couldn’t read well enough to read the deer resistant list!

Tips for Growing Vegetables in Shade

Chard can successfully be grown in partial to light shade.

We humans used to be mostly foragers and obtained our nutrition by being hunter-gatherers. Foragers use to enjoy a comparatively leisurely life with good nutrition by working just a few hours each day, while those in agricultural communities toiled almost ceaselessly and had comparatively poor nutrition. What happened to make us the agricultural society we are today?

The end of the ice age occurred at the same time that foragers migrated around the globe. Warmer, wetter and more productive climates may have increased populations in some regions. The increased population pressure. may explain why some communities of foragers began to settle down and begin growing food. The rest is history. Many of us are returning to growing and producing our own food whenever we are able. Even on a small scale, a garden, a few fruit trees, a chicken or two or three, all help to put healthy, nutritious food on our table.

There are three types of shade. A partially shady location is one that receives 2-6 hours of sun, either in the morning or in the afternoon. It can also refer to a full day of dappled sunlight. Most edibles that prefer full sun will grow in partial shade, especially if they receiver their hours of fullest sunlight in the morning. A lightly shaded garden receives an intermediate level of shade. While it may receive only an hour or two of direct sun during the day it is bright enough the rest of the time to allow a variety of edibles-especially leafy greens to grow. Full shade is found under mature trees that have dense, spreading foliage. Unpruned oaks and maples cast this kind of shade in summer. Heavy shade under mature evergreens is often dry. A fully shaded location like this is fine for woodland plants but in not a great place for edibles.

Whatever level of shade you have in your yard, make the most of the situation. First, if you have the choice, opt for afternoon shade. Shade in the afternoon is more hospitable in the summer when the sun is fierce. The severe temperature swings created by a combination of shade in the morning and blazing sun all afternoon are difficult for most plants to withstand. Gardens facing east will enjoy bright sun all morning and shade in the early afternoon.

If you garden under deciduous trees you can give plants a head start by starting the seeds indoors or direct seeding early before the trees leaf out. All trees, however, bring roots as well as shade to the garden and tree roots will compete with garden plants for water and nutrients. Any plant grown where there are tree roots will need extra water and fertilizer to make up for the competition. If you can’t get the garden out of the dense shade of trees, at least get it past the tree dripline where most of the roots are located. If that’s not possible, it might be better to plant in containers beneath the trees to prevent tree roots from invading the root zone of your vegetables.

Cherry tomatoes grown in partial shade are slower to ripen- Be patient

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.

Ways to Celebrate Earth Day

Adelyn Biles in my old garden with her drawing.

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 your own corner of the ecosystem. Our connection to the earth is one of the most valuable lessons we can share with our children.

Start summer early with the kids by planting a fruit tree, flower, vegetable or native shrub now. Planting something is having confidence in the future. Earth Day is always on April 22ch and celebrates the natural beauty of our planet, our clean air and reminds us of what we can do to keep it healthy. Earth Day is a day of education about environmental issues and is now a global celebration. 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.

Fragrant flowers like carnations and dianthus smell like sweet cloves.

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.
