Rocks

Rocks are the easiest sculptural elements to incorporate into a garden, creating natural-looking landscapes. They add color, contrast, interest, and require no maintenance.

When strategically placed they will keep vehicles from driving over driveway edges and harming plants or grass located in areas susceptible to damage. Large boulders can be incorporated into the landscape providing a great deal of aesthetic appeal.

Two Ton Rock Placed As Outcropping

Now is the perfect time to design and place landscape boulders. Arrange around plants to determine where they will fit best. They come in all sizes and colors, from giant Stonehenge-type slabs to tiny pebbles the size of peas in colors including brown, tan, red, pink, blue, green, white, black and gray.

The big concern with rocks is their weight. You will need equipment and assistance to transport and place them. Positioning is very important; everyone involved must be extremely patient and willing to take as much time as necessary. Sculptural boulder elements can be expensive to buy, transport and place, limiting your use of them in the landscape.

Here are some guidelines to keep in mind when adding boulders, rocks or smaller stones to your property.

• In nature, rocks repeat naturally. If you have only one rock outcropping in your yard, add more to create a theme. Vary sizes and spread them throughout garden beds. Use two to three per bed at most, arranged in random patterns simulating nature.

• Allow large specimens to complement nearby plants. Smooth flat rocks are natural seats.

• Measure the area where they're going so you know what size to look for. Quarries and stone yards often let you choose your own.

• Select landscape stone as carefully as your plants. Check size, color, texture and shape. Be innovative in utilizing specimens. Stagger largest ones for partial screening and a dramatic effect. Install in the soil as steps, using large flat slabs horizontally arranged on slopes.

• Smaller rocks can be used for low retaining walls creating charming additions and a manicured look to rustic, natural gardens. Flat rocks, up to a foot or so wide, can be stacked without mortar for low walls.

Sitting Walls

• Rockscaping enhances water features like small ponds. Create waterfalls in natural or artificial streams or ponds.

• Imply a riverbed and establish an effective, ornamental drainage swale. Cover soil surface of a meandering U-shaped or V- shaped depression with consistent aggregate material like rounded river gravel. Vary rock sizes for a natural stream design.

Drainage Swale

Consider these books, www.workman.com, for working with landscape stone:

“Listening to Stone: Hardy Structures, Perilous Follies and other Tangles with Nature,” by Dan Snow (Artisan, 2008)

“In the Company of Stone: The Art of the Stone Wall,” by Dan Snow (Artisan, 2001)

Search the Internet for other books on using stone in the landscape.

Spring Gardening

With spring finally upon us, many plants are rapidly growing.

If perennials browned and died back last fall and weren’t cut, do it now. Examples are liatris, verbenas and black-eyed Susans. Clip liriope and perennial ornamental grasses. Use shears, string trimmers, or a mower on its highest setting.

Some winter or early spring flowering perennials like leatherleaf sedges (Carex buchcananii) and evergreen sedges (C. pendula) shouldn’t be cut back. They can be slow to renew or not renew at all. Don’t prune dianthus or winter-blooming hellebores, except browned leaves.

After daffodil and tulip flowers fade, cut stems that held flowers (scapes) to the base. Leave daffodils in the ground. Minor bulbs like crocus, hyacinthoides and scilla will season without cutting. Tulips are best dug as the foliage yellows. Lay bulbs in the sun to dry for about two weeks, protected by chicken wire cages if wildlife is a problem. When bulbs dry, knock off soil, separate bulbs, place in porous bag with vermiculite to keep them firm and store in cool dry location until you replant in November.

Forsythia

Prune forsythia, floweringquince and winter jasmine after blooming. Cut forsythia in half or to a height where it won’t require pruning again until after blooming next year. Flower buds will form on this year’s new growth. Floweringquince doesn’t need pruning if it flowered well this year. When more wood than flowers show, cut back to 18”. Winter jasmine only needs pruning when it’s overtaking an area and is growing where you don’t want it. It can be cut to 12” after flowering. Only renew overgrown plants that have lost ornamental value.

Floweringquince

Incorporate organic material into root zones of plants. It helps tree roots retain moisture and increases ability for soil to hold nutrients. Lay fine textured compost or Leafgro 1-2” thick around root systems at tree base. It’s the perfect complement to fertilizer. Don’t pile against bark.

Insects are waking up and disease-causing organisms that were dormant during winter are emerging. Spray dormant-oil insecticide or fungicide. Spraying now will insure the least negative impact on the environment by reducing necessity for additional spraying during growing season. If you don’t want to use a petroleum-based product, mix 1-cup vegetable oil with 2 tablespoons liquid soap (not dishwasher detergent). Slowly add one gallon of water to create your spray. Use a sprayer that never contained insecticide or weed killer to apply. Only use dormant-oil on plants when it is the recommended method of pest control.

Utilize low, inexpensive fencing around areas where rabbits munch. Eighteen to 24” is tall enough. As leaves mature, rabbits stop eating foliage. Mothballs, dried blood, castor oil, and cayenne pepper have limited success and need to be re-applied frequently.

Try protecting plants from deer with fences, walls, chain-link or deer fence. The latter is rigid black plastic mesh 8’ tall that can be snaked around trees, through woods, and be self-supporting. Other popular remedies include motion-sensor activated water sprays, lights, sound, soap, hair and animal-based products using egg mixtures. Check with your local garden center for deer-resistant plants and the Cooperative Extension Service, www.csrees.usda.gov/Extension/index.html.

A Garden of Ordinary Miracles An Alphabet Book

I can’t imagine a better time to review a book on flowers than the beginning of spring.

“A Garden of Ordinary Miracles An Alphabet Book” (Universe Publishing, 2012), by Robert Zakanitch, is a beautifully illustrated text that offers the names of ordinary flowers and what they look like. The author has hand-rendered the images and organized the flowers alphabetically.

It will teach children and adults what flowers look like and how to use them in the garden. This 64-page book lists each plant beginning with A and ending with Z. Each letter represents a flower commonly found in the garden that will add color.

Children will enjoy the illustrations, and adults will learn that flowers can be referred to by common or botanical name. The author prefers illustrating flora by common name making it easier for children to learn names of the plants and what they should look like. Adults will learn that some flowers are better identified by scientific names to find the correct plant.

For example, the first plant in the “Alphabet Book” is azalea, but if you want to find an azalea at a garden center, it would probably be found under its botanical name of rhododendron. If your attention was captured in early spring by the plant called forget-me-not, its correct botanical name is myosotis and would be found under that name. If you like Johnny-jump-ups find them under viola. That’s the proper genus for this violet. Larkspurs will be found under the botanical name of delphinium.

Children will learn flowers they like as they read or look through the collection of Zakanitch’s storybook-style book. Drawings are woven through it to create the story line. Adults can search for flowers that they might have forgotten to plant in their garden in 2012, learning to identify them by their common or botanical names.

There is so much to look at and enjoy on each page. Readers will be enchanted and entranced by the intricately detailed and whimsical nature of Zakanitch’s art, combining pen and ink and color on the same page. It’s worth acquiring for the artwork alone and fascinating to discover which flowers were used because of their common name and those listed by botanical names in order to achieve the A to Z plant listing. If you have a question about which name is common or botanical, use a horticultural text such as ”The American Horticultural Society Encyclopedia of Plants & Flowers,” edited by Christopher Brickell.

The Elegant Garden

Welcome to 2013!

Now that we have entered the winter months and most of us are spending more time indoors than out, it’s the perfect time to catch up on reading some exceptional gardening books. Buy one for yourself or the friend you might have forgotten during the holidays.

I recently had the pleasure of enjoying “The Elegant Garden: Architecture and Landscape of the World’s Finest Gardens,” by Johann Kräftner (Rizzoli International Publications, 2012), www.rizzoliusa.com. This gorgeous collection of photography is representative of magnificent architecture in the landscape and offers ways to create your own garden paradise by extracting ideas from international grand gardens of the past and present.

The Elegant Garden

Kräftner introduces gardens as “a place of eternal life,” referred to as paradise in the Middle East, and has included historical information on gardens throughout the world beginning in the eleventh century B.C., going so far as to reference the Garden of Eden.

The designs depicted in the photographs are defined in depth throughout the book. Ranging from classical to contemporary, by following principles in this text you can embody garden spaces and create your own “pleasure ground.” Castles, sculptures, formally trained shrubs, garden rooms, orchards, vegetables, Asian, European, Moorish, American, modern and classical landscape designs are all represented in this superbly illustrated, 430 page hardcover tome that contains photography that will spark ideas for your own property.

The hundreds of gardens in this book promise to instill confidence for do-it-yourselfers and help develop a better grasp of how to envision space. Creating your outdoor comfort zone and comfortably flowing from one garden space to another are clearly defined by photos. This book abounds in landscape design ideas from around the world, containing approximately 850 high quality, full color photographs and superlative historic interpretation – from Rome to the present and a view of what each culture in between considered aesthetically pleasing.

Recognizing that designs occur onsite and not simply on a piece of paper, personal style, planning, recognizing the bones of a garden, planting for 12-month interest, color, architectural features, balance, scale and spatial definition are some design principles quickly discovered by simply perusing this outstanding book. This book contains images ranging from formal to rural, showing them in winter, spring, summer and autumn.

This book is well suited for your coffee table. It is the perfect inspiration to keep you focused on your landscape during the winter months. The photography, international appeal and inspiration alone are worth it. Cost: $60.
