Planting for Drought Tolerance & Deer Resistance in the Rogue Valley

 Article By: Christie Mackison, Shooting Star Nursery

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

Drought Tolerant Plants:

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

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.

How to find deer resistant plants

Deer can be very neighborhood specific so look around your neighborhood. Drive or walk around heavy populated deer areas like Ashland, Jacksonville, and in the hills of east Medford. Observe what has been chewed.

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 the time of year you plant- deer are especially hungry in fall and winter they can graze on almost anything.

September 2022: Garden of the Month

453 Tucker Street

This time of year, many Ashland gardens are starting to look little tired, victims of prolonged excessive heat and thirst.  Ornamental grasses do particularly well in these conditions and those gardens that feature them continue to thrive.  Elizabeth and Gerard Boulanger’s gorgeous front yard at 453 Tucker Street is a great example and is the Ashland Garden Club’s Garden of the Month for September 2022.  It requires only a modest amount of water to put on a beautiful show year-round.

The Boulangers moved here in June of 2021.  They tidied the front yard, particularly giving room to the Japanese blood grass, the leaves of which are currently a stunning dark purple, so it wouldn’t get lost in the thicket.  Their display of ornamental grasses highlights the varieties of colors (some of which change seasonally), blooms, shape, and blade structure. The large green grasses directly in front of the house turn a bronze color in Autumn.

They have done a lot of work on the side yards during their short tenure here, including a massive restructuring on the western side, terracing the space to make it more usable by creating a bocce ball/horseshoes court and pleasant patio on different levels.  The handsome block retaining walls were created by Jorge Regalado and his crew from Firststone Masonry.  Elizabeth credits Gerard for the design of this area, but admits to making some suggestions.  Dwarf gingko trees border the wooden stairs on one side and buddleia shrubs border the other side.  They have started a hedge along the fence in back, along the north side of the property, to soften the near part of the nice view toward the hills.  Trees include juniper, maple, and ash.

Elizabeth and Gerard personally work in the yard when they can and clearly enjoy the plants.  Particular favorites are Pacific northwest myrtle, hydrangea, sweet peas, dogwood, and lavender.  Christie Mackison of Shooting Star Nursery has advised the Boulangers on plant choices.
