Garden of the Month: April 2015

Spring has arrived (though, it feels like it began in January) and gardens all over Ashland are making us take notice. One such garden is found at the home of Beverly and Dick Gergen who moved into their Ashland home August 2003. The Gergens previously lived on six acres above Talent where they created large flower and vegetable gardens. After deciding a home closer to town with a smaller yard made more sense, they moved and set about creating the lovely garden you see.

Originally, the front held a flat, grass covered area struggling with large tree roots, all competing for water and nourishment. This also meant that people walking by looked past the yard and into the large living room windows. Beverly and Dick decided to create something more interesting for the passersby and to enhance their pleasant and friendly neighborhood.

Beginning in 2006 Ian Wessler, a friend, fellow Siskiyou Singers member, and garden designer, was asked to help convert the front into something more beautiful. As you will see, he definitely did! Working with Beverly and her vision, this Asian inspired planting is on its way to being a standout even beyond their immediate neighborhood.

Before planting, a berm of fertile soil, supported by huge granite boulders, was created and became the foundation for the plantings: Japanese maples, rhododendrons, several varieties of daphne (including a lavender color, currently in bloom), weeping hemlock, scarlet oak, fern-leaf false cyprus, dwarf Norway spruce, shore juniper, dogwood, skimmia, viburnum, Japanese snowbelle, enkianthus, helleborus, lamium and others.

Many Asian touches lie within the garden – a slightly tipsy crane greets visitors coming down the path, glass floats live near the water feature, bells hang in the trees, and beautiful pottery and lanterns nest among the shrubs. One clever feature I particularly liked is a “lawn” pathway, much easier to walk on than gravel, and small enough to maintain. Even an old family bear stands back among the trees, keeping watch.
Like so many other gardens in Ashland, this one was planted with deer in mind. Nearly all the plants are considered deer resistant, and except for a few nibbled azaleas, the choices appear to be working.  While the deer can take a lot of fun out of gardening, Beverly says, “the planting, pruning and general garden maintenance are therapeutic. When my garden is happy, I am happy.”

I know I’m happy, just looking at it.

Planting for Drought Tolerance and Deer Resistance

Destructive deer and hot, dry summers are two very common issues in the Rogue Valley. Drought tolerant and deer resistant plants are a good combination to aim for because the qualities in plants that repel deer can often be found in drought tolerant species- such as heavy oil content, textured or hairy foliage, strong odors, and tough, less succulent leaves. The key to keeping drought tolerant plants happy and more unpalatable to deer is to give them the habitat they are used to- so don’t water them every day just because its 90 degrees!

Good drainage is usually essential- if you don’t have it, you’ll probably have to water even less

No heavy fertilizing: Use only organic or slow release fertilizer if called for at time of planting. Over fertilizing will attract deer. If the plants look yellow it is usually from too much water, not lack of fertilizer.

Dedicate an area to drought tolerant plants: Don’t mix plants that need regular water with drought tolerant plants. Do not put them on the same irrigation system & timer or one group will suffer.

Do not over water! It’s best to plant drought tolerant plants in early spring or early fall so they can get established with the rains.

  • Once established many plants do not need summer water.
  • They will only need an occasional deep soak.
  • Don’t plant them where they will get extra water from lawn areas or runoff from other irrigated areas.

 How to get good drainage:

Mound up soil when making new beds or planting a new plant. Create a berm. Plant drought tolerant plants on a hillside or slope

Mulch with at least a 1″ layer of 1/4″-io gravel to keep dirt from rotting the crown of plant, to retain moisture during heat and keep plant roots warmer in winter

For clay soil amend with 1/4″- io gravel (sharp edge, no fines) and compost will help break down clay over time.

 How to water drought tolerant plants

Observe- most plants need to dry out before the next watering- stick your finger a few inches into soil (well below mulch, which will feel dry), if it is cool and damp, don’t need to water yet.

Infrequent But Deep Soak: This trains plants to have deep roots, not shallow. Often a deep soak every 2 weeks in heat of summer is enough- easier to do with drip irrigation than sprinklers

Watering rule of thumb (depends on site and soil type)

  1. 1st year of planting water deeply once a week for first month of summer,
  2. Then water once every 2 weeks for 2nd and 3rd month of summer
  3. Water once a month the 2nd summer and don’t water again.

 How to find drought tolerant plants

Look to natives- can tolerate summer drought and winter wet

Look to Mediterranean plants- similar climate (also cold hardy Australian and northern California plants, hardy desert plants/succulents) get help from your local nursery!- we’ve talked to countless customers and worked in our own gardens and have seen what works

How to find deer resistant plants

  • Look around your neighborhood drive or walk around heavy deer areas- Jacksonville, hills of east Medford, wooded parts of Ashland- observe what has been chewed- deer can be very neighborhood specific
  • Read lists, but be ready to experiment
  • use Liquid Fence, Plantskydd, or similar product on all new plantings to discourage initial browsing
  • Use cages around most new trees- to prevent antler damage and new growth chewing
  • Deer damage can depend on time of year you plant- when deer are especially hungry in fall and winter they can graze on almost anything
  • Use poisonous, strongly scented or sharply textured plants (grasses, sometimes prickly/thorny textures, fuzzy/hairy leaves, pine needles, etc.)
  • Talk to your local nursery- we know from our experiences and those of our customers and landscapers what has worked and what hasn’t
