Companion Planting

The theory of companion planting is by placing beneficial plants together they help each other grow.
Some ways companion plants help each other are:

  • Taller plants can provide shade for sun-sensitive shorter plants.
  • Vining plants cover the ground below taller plants for weed control, or to support vining plants.
  • Companion plants discourage pest, for instance onions repel some pests,
    while other companions, like marigolds, lure pest away from desirable plants.
  • Companion planting can attract beneficial insects to the garden, and improve flavor to some fruits and vegetables.

Below is a beginner’s guide to companion planting.   20141016_171506

All pumpkins and squash will develop powdery mildew symptoms if weather conditions favor the fungus. Resistant or tolerant varieties develop symptoms more slowly and maintain leaf coverage later in the season. For more information about controlling powdery mildew, see the New England Vegetable Management Guide, found online at http://www.nevegetable.org/.

 All varieties should be trialed on a small scale to determine whether they are suitable for your growing conditions, and markets.

Garden of the Month: September 2014

Garden of the Month: 913 Mary Jane
by Kaaren Anderson

Richard Lee moved into the house at 913 Mary Jane and began the first steps to grow plants and landscape the yard, beginning with the foundation plants of nandina, green spirel euonymus, and Oregon grape.
Paige joined him in 2005 and together the couple created the garden you see today. In that year, the front landscape changed dramatically when the house was remodeled. This process created a mound of excess soil which they creatively decided to leave, adding plants that began with dwarf nandina and mugo pines.

Richard installed a 1400 square foot greenhouse in the backyard where he began raising plants from seed, including perennial geraniums which are planted inside the yard as well as on the street side of the photenia hedge. For color they have annual geraniums, hibiscus, dahlias and zinnias, with the zinnias currently reaching a height of 64”. On the street side, also grown from seed, are echinacea and coreopsis. On the mound was added a cercis tree and a bakers Cyprus which is a native tree to the Siskiyou mountains. In front of the picture window is a coral bark maple.  Access to TID water for part of the summer helped keep the plants happy and healthy.

In the springtime you will also see columbine, lilies, gladiolus, daisies, crocosmia and camilias, which I know would make the garden even more spectacular than it is now. But though Paige worried that her garden wasn’t at its best, I assured her that even at this time of year, and in one of the the hottest summers on record, it stood out as a jewel.

Thank you Paige and Richard for sharing your garden with us!

Garden of the Month: August 2014

Tim and Kathy Simonsen established their garden in 2006.  The front of the house was uninteresting so they added a wide craftsman style 1133 Beswick Waycovered porch. This just invites you to sit down in the comfortable rockers and enjoy the view. Two hanging baskets of red geraniums adorn the porch and two large pots with sweet potato vine and some other greenery bracket the stairs.

Ken Cobb designed and installed the compact flowing garden.  First he removed junipers, ivy and St. John’s Wort. Then he designed a wide curving walkway out of tan colored stamped concrete with a few steps. This separates the upper garden from the lower area. Next the Simonsen’s wanted a large water feature; and after looking for just the right boulder Ken built the waterfall to the left of the stairs. The birds love to stop by for a drink and sit to enjoy the melodious sounds.The pond is kept full with a couple of “drippers” with the irrigation system.

The upper terrace has Pieris Japonica, Gold Mound Spirea, a Japanese Maple, Heavenly Bamboo, a Mugo pine, a Japanese Maple and Scotch Moss.

Below the path is Blue Star Creeper with a small swath of green lawn at the owners request. Mugo pines, Yellow Twig dogwood, Red Twig dogwood, a Strawberry Tree and three more Japanese maples with Phlox, Wooly Thyme and Kinnikinnick fill in the lower terrace. The mature garden is now a very natural and interesting place. The low maintenance garden does require pruning, weeding and shaping two or three times a year to keep it looking it’s best.

Tim and Kathy have a lovely hillside garden to enjoy and share with the many walkers who stop to admire and chat.

Garden of the Month: June 2014

IMG_0151Pam Lucas works nearly every day in her beautiful garden at 420 Taylor Street and it shows! Her husband Sherm does some of the heavy work, but mostly this is Pam’s labor of love. They purchased the house in June of 2005, but Pam was still working then and didn’t have much time to devote to the yard. She did design and have constructed an interesting complex of decks, walkways, and arbors that look so good now with the garden she has established to replace the lawn, since retiring in 2008. Pam also designed the unusual deer fence. Interesting sculptures dot the property,IMG_1407 many of them metal art by Les and Diane Rasmussen of Steel My Art. Some are collaborations between the homeowner who found metal pieces and asked Diane to work with them, including a wonderful angel made from a bomb and other parts! There are actual headstones, purchased at a yard sale. Large boulders were brought in to add texture and background. The trees are tended by an arborist who visits every other year. Recently, they had the irrigation system improved by a professional.

In back, large Douglas firs create a backdrop and privacy with pin oak, English laurel and bamboo. In front, Japanese maples, thunder cloud plum, flowering cherry trees, and mountain ash provide a canopy. Pam has combined many ground covers to create a colorful and textured surface surrounding a river rock walkway to a deck. Gorgeous collections of artfully placed potted color adorn the decks.

IMG_0182Among the plants in pots are calibrachoa, bee balm, lobelia, mums, begonia, fuchsia and a rare oregano. A well-established wisteria climbs the arbor and provides shade for the largest deck. Trumpet vine and honeysuckle adorn the lattice that lines the driveway, with a little pyracantha to discourage deer nibbling. An incense cedar and yarrow thrive to the right of the driveway, but deer have feasted on most other things that Pam has tried there.

To the right of the front door is a specimenIMG_0189 yew. The front includes yucca, lavender, smoke tree, barberry, rosemary, daphne, sedum, mahonia, zebra and other grasses, gaura, manzanita, iris, lithodora, several kids of euphorbia, columbine, lupine, heuchera, crocosmia, agastache, eryngium (sea holly), spiderwort, Russian and other sages (including a wonderful blue flame sage), and many more ground covers

It’s hard to believe that a retired accountant, not an artist, created this garden.
