Beneficial Gardens in a Small Space

waterfall_2He told me that his was a one-of-a-kind garden, unique in such a small space and would I be interested in visiting some time? I love being invited to tour all types of gardens but I had an inkling that the garden of Rich Merrill, former Director of the Horticulture Dept. and Professor Emeritus at Cabrillo College, would be something special.

It was a beautiful morning when I arrived at Merrill's garden overflowing with flowering plants, small trees, edibles and water features. Many large boulders, surrounded by pebbles, caught my attention in such a small space. All part of the design to attract beneficial insects I was told. His organic garden is teeming with small beetles, spiders, predatory bugs, syrphid flies, parasitic wasps and lacewings. It's the ideal method of pest control, environmentally safe and free of cost.

While admiring his lovely garden, Merrill shared his knowledge of beneficials- from insects to birds to spiders to frogs and beetles. They are all part of the ecology of a successful habitat garden. I could barely keep up, writing down notes on my yellow legal pad as he weaved a story about how each of the elements in his garden contributes to its total health. I was never able to take one of his classes at Cabrillo College so this was a real treat. My own private class.

The wide diversity of plants in Merrill's garden provide moisture, shelter, prey and nutrition in the form of santivalia2nectar for carbohydrates and pollen for protein. His plants are "beneficial" plants because they foster beneficial insects. It just so happens  that many of these plants are also beautiful in the garden. Some of his favorites include composite flowers like sunflowers, marigolds buckwheat, scabiosa and santivalia or creeping zinnia.  They have flat  flower clusters with accessible landing platforms and small nectar and pollen to make it easier for insects to feed. They in turn eat the tiny eggs of the bad bugs in your garden. His is a complete ecosystem.

This 800 square foot garden happens to be in a mobile home park but any small space could be designed to be as beautiful and full of life as Merrill's. Most of my clients ask for a garden filled with color, hummingbirds, songbirds, butterflies and wildlife so I came away with lots of great ideas.

blue_thunbergia2Once a teacher, always a teacher. Merrill gave me a handout he'd prepared for Renee Shepherd of Renee's Garden, explaining in more detail why he lets the broccoli go to flower to attract beneficials and why he allows aphids on his cruciferous vegetables to feed the beneficial insects when prey is scarce so they are on hand should he have an outbreak of bad insects that might ruin his flowers and plants.

As we strolled within a border of palms, olive trees, phormium, bottlebrush, Marjorie Channon pittosporum and cordyline, Merrill showed me his philosophy of right plant in the right place in action. Asclepias curassavica, commonly called Mexican Butterfly Weed, has self sown on its own in unexpected spots. One happened to come up next to the gorgeous blue thunbergia by the pondless waterfall making an awesome combination. Both monarch butterflies and hummingbirds enjoy the nectar.

Next to a red salvia, a red and white bicolor Rose of Sharon made it's home. Merrill lets all his plants intertwine and the pink flowering Heckrottii honeysuckle was already inching up into an olive tree. Other salvias in his garden include Hot Lips, San Antonio and San Jacinto. There isn't room to grow any of the larger salvias, Merrill explained. He swears he doesn't know where the brilliant blue one came from. Must be from the "fairy dust" his wife, Dida says he sprinkled over the garden to make everything grow so lush.

She loves flowers for fragrance and cutting so in several beds they grow gardenia, lemons, roses and alstroemeria among the alyssum which is a prime syrphid fly attractor. Several bird of paradise, obtained from different locales in the hopes one will be hardier grow beneath a tall palm.

Merrill grows only the vegetables that do well and are the most nutritious like kale, onions, garlic, broccoli and collards. He enjoyed growing cucumbers this year and has a large pumpkin in the making for his grandson. The rest he gets from the farmer's market. He had developed his own strain of elephant garlic which is actually a leek and has a milder flavor than garlic. I left his garden with a gift of elephant garlic and lots of inspiration.

The Giants’ Garden

AT&T_Park 3A few Sundays ago I spent the afternoon at AT&T Park watching the Giants play baseball. It was kids day. Hundreds of Boy Scouts were attending the game in uniform. Kids were everywhere eating peanuts and wearing the orange and black team colors. Some were sitting with their grandparents, some very, very young fans in their parents arms being smeared with sun screen.  It was a beautiful day on the San Francisco Bay. Unfortunately, the team didn't get the memo that we were supposed to get another win against the Diamondbacks. Oh well, there's always next year.

A friend forwarded an article he saw in the SF Chronicle by Janny Hu recently about the Giants plan to create an organic garden behind the center field wall. The Giants Garden would be created between the left and right field bleachers in an area that is now concrete and an adjacent area where replacement sod is grown.

Plans for the edible garden include hydroponic troughs, concrete planters and living green walls which would supply produce for some of the parks' concessions, serve as an open air dining area and a community classroom during the offseason. If you're hankering for a nice kale and strawberry salad next season while you watch the game you're in luck. The Giants hope to have the garden ready for Opening Day 2014.

If the Giants can do it, you can, too. We all want the area around our homes to be beautiful, welcoming, productive, useful.  In designing landscapes for people I strive to integrate vegetables, herbs and fruit trees with flowering shrubs and perennials to feed the family while attracting hummingbirds and other wildlife. Not everybody has room for a separate vegetable garden and companion planting is a good way to avoid problems with pests and diseases.

Plants when attacked by pests, exude chemicals and hormones that actually attract nearby beneficial insects. Perennials like agastache, coneflower, coreopsis, scabiosa and yarrow are rich in nectar and pollen and  irresistible to beneficials. Many herbs also attract beneficials.  Cilantro in bloom is one of the top insectary plants.  Caraway, chervil, dill, fennel, lovage and parsley flowers also attract beneficials and are easy to grow among your other plants. Allow your salad and cabbage crops to bloom.  Arugula and brassica flowers are much appreciated by beneficials.

Plants like lettuces, spinach and swiss chard look great in the flower bed and flowers make great companions in the vegetable garden.
Dahlias repel nematodes. Geraniums repel cabbage worms, corn ear worms and leaf hoppers.  Plant them by grapes, roses, corn and cabbage. Marigolds discourage beetles, whiteflies and nematodes. They act as trap plants for spider mites and slugs. A word of caution,  don't plant them by cabbage or beans. Nasturtiums act as a barrier trap around tomatoes, radishes, cabbage and fruit trees. They deter whiteflies, and squash bugs and are a good trap crop for black aphids.

Herbs that help deter pests. Catnip/catmint repels mice, flea beetles, aphids, squash bugs, ants and weevils. Chamomile improves the flavor of cabbage, onions and cucumbers. It also accumulates calcium, sulphur and potassium, returning them later to the soil. As a host for hoverflies and good wasps it increases productions of essential oils in herbs. Summer savory repels bean leaf beetles and improves the flavor of beans. All beans enrich the soil by fixing nitrogen.  They are good for planting with all of your vegetables except onions, garlic and leeks.

Dwarf fruit trees can also find a place in the smaller garden. They can be grown in large pots or half barrels on the deck, too. Dwarf Garden Delicious apple is self-fertile and bears at a young age. Compact Stella cherry is also self fertile and is a good pollinizer for all sweet cherries.

If it's almonds you crave, plant a Dwarf Garden Prince almond. This compact 10-12 ft tree blooms mid-season with beautiful pale pink blossoms. Dense attractive foliage and good quality sweet almonds make this tree a nice addition to any garden. A patio-sized peach for smaller yards is the Dwarf Southern Flame.  Large, yellow, aromatic freestone peaches are firm, crisp and melt in your mouth. Tree height is just 5 ft and the fruit ripens early to mid July.

Planting flowers and edibles together makes sense and good use of your garden space.
 

Kids & Gardening

Flame_Skimmer_dragonflyIn the summertime, kids have lots of time to enjoy the great outdoors. What better way to teach them how our planet works than to let them grow something in their own garden. Share your enthusiasm for gardening by getting your kids or the neighbor kids interested, too. You'll find sharing your knowledge with a child particularly rewarding and you will have helped create a fellow gardener for the rest of their life.

It may be July but it's not too late to start. Make it enjoyable for everyone by giving kids their own section of the garden or yard to do as they please. I planted pansies as a child in my special area. I also had a couple of big pots filled with potting soil to start my own seeds. Size doesn't matter as long as you let the child choose what they'd like to grow.

Teach children about beneficial insects like butterflies and lady bugs. Good bugs help plants by pollinating flowers or preying on insect pests. Make your garden a more inviting place for these helpful insects by planting lots of flowers and herbs to attract them. Flowers with umbrella shaped clusters of small flowers such as cosmos, zinnia, black-eyed susan and yarrow are favorites of butterflies.  Lady bugs like a pest free garden and will patrol your plants looking for any tiny insects and their eggs.

I remember when I was little and had my own garden patch how excited I was to see a dragonfly. My father was happy, too, as they are a great way to control mosquitoes and other pests. They're the top predators of the insect world. I was fascinated by their bright colors- some reddish orange, some blue, some purple. By  planting a variety of plants and flowers to attract them they would visit my little garden often. They seemed to find a water source to lay their eggs on their own.  I was amazed at how fast they could fly. I've read they can reach speeds of 30 mph.  They are an important part of my early gardening experience.

Edible flowers are also fun for kids to grow. Some common ones to try are tuberous begonia petals that 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 in ice cubes like violas, fuchsias, geranium, stock and thyme. The blossoms of beans and peas can be added to a salad or sandwich or use them to decorate the tops of cupcakes and cookies.

Plant a pizza garden.  Use a hose to form a round garden shape and border it with stones or another type of edging of your choice.  Divide the "pizza" into slices using stakes or one of your plant varieties such as basil.  Add stepping stones for the pepperoni slices and plant each section with one tomato plant and one green bell pepper and fill in with garlic, oregano, chives and basil.  By summers end you'll be harvesting the makings for a delicious home made pizza.
 
Kids, even older ones, like hiding places, so grow one in the garden.  You can plant tall growing sunflowers in a circle, leaving a space for a "door" that kids can crawl through once the flowers have grown.  Or build a simple teepee out of fallen branches or long gardening stakes and plant bean seeds around the outside.  Scarlet runner beans are also good and have tender, young pods like green beans in addition to bright red flowers that attract hummingbirds.  Beans grow fast and soon make a great secret hiding place.
 
Another fun project is growing birdhouse gourds.  This fast growing vine can beautify fences and trellises during the growing season.  In the fall, dry and hollow them out to make birdhouses or gorgeous crafts.  You can burn patterns into the surface and stain the gourds with shoe polish making beautiful objects of art that make great gifts.  
    
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 swallow-tail butterflies.  Other easy to grow flowers for cutting are snapdragons and who hasn't pinched these to make faces ?

Besides flowers, fragrant plants like lemon basil, lime thyme, orange mint, chives, sage and other herbs engage the senses and can be included in a kid's garden. Lamb's ears are soft and furry.  Get a kid interested in gardening and they'll be happy for a lifetime.
