Wait! What if we had a clean slate…… Don’t start by picking out the plants

LANDSCAPING

Page 2: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

WHY “DESIGN”?

Create a plan to extend indoor space outdoors

Take advantage of natural features

Assess limitations Install complementary

hardscape Plan efficient irrigation Selecting plants that fit

design

Or improve your curb appeal?

Page 3: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

SOME DESIGN PRINCIPLES

Scale Perspective

Don’t make small spaces boxier or visually closed in

Balance Unity Rhythm, repetition & unity Accents

Page 4: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

WHAT TO CONSIDER? User’s wants &

constraints Do you want to

spend your free time maintaining the landscape?

Climate! Site Analysis Materials Budget

Page 5: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

WHAT DOES THE USER WANT?

Consider activities, routines, & traffic patterns Play area for kids? BBQ & entertainment Area for pets Outdoor rooms Orchard or vegetable garden Public Area (curb appeal -

seen when entering property) Maintenance Things change

Page 6: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

CLIMATE CONSIDERATIONS: DON’T TRY TO FIGHT IT

“Mediterranean” Temperature Range (plus snow load) Dry Summers Hot summers

Evergreen vs Deciduous trees (allow summer shade and winter light)

Vegetable garden in sun, afternoon shade? Outdoor living area in shade

Microclimates

Page 7: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

SITE ANALYSIS

Notice wind, sun, shade patterns Soils Topography

Terracing of steep slopes Retaining walls

Preserve best features Traffic patterns Hide/screen “ugly” stuff

Neighbors, sheds, services AC, garbage cans, compost, propane

tanks, clothes line Potential hardscaping

Patios, walkways, driveways

Page 8: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

MATERIALS & BUDGET

Suitable for our area Freezing & thawing Gauze tents vs shade

tree Metal vs PVC fixtures

Appropriate for intended use Paving in high traffic

areas Fence or wall vs hedge

Plants Year round interest Lower maintenance Consider native plants

Think about long-term cost – design efficient irrigation system

Layout plan & start with key elements

Plants grow, start small Use cheap or free

materials Mulch, DG, river rock Recycled materials

Page 9: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

REGULATIONS & OTHER CONSIDERATIONS

Fences over 6’ tall need “engineered design” for wind, etc

Don’t try to hide propane tank Turn-around for fire trucks Consider safety (trip hazards,

nefarious characters, fire)

Page 10: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

DESIGN STEP #1

• Use graph paper and make map to scale. May also use available software Include

North Point Undesirable and desirable features Views House, Garage, Other buildings Trees, Rock Outcroppings Existing Walls, Driveways, Paths Contour of Land Direction of Surface Flow of Water Sun / Shade Pattern

Page 11: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

DESIGN STEP #2 DESIGNATE THE USE AREAS May use tracing paper to make layers over existing site Determine if each area is functional in relation to house

Is clothes line easily accessed from laundry room? Are views from house as intended?

Fit use areas together with traffic flow Are the driveways, walkways and parking areas easily

accessible to house? Does it flow/work?

Are service areas not in view of outdoor living space or windows from inside?

Locate septic tank/lines and easements

Page 12: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

DESIGN STEP #3 FINALLY WE GET TO THE PLANTS!!! Draw to Scale Choose plants for water-wise, fire resistant and deer

resistant landscaping, attracting pollinators Select with these characteristics in mind:

Form Color Texture Seasonality (time in bloom) Overall aesthetic value

Select plants or groups of plants to meet the specifications of your plan and design

Page 13: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

PLANT SELECTION CONFLICTS

Redding Water Smart Gardening

Choose what’s relevant to you:

Fire Resistant? Deer Resistant? Drought

Tolerant? Native Plants? Pollinators?

Page 14: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

EVALUATE BEST LOCATION

Consider size at maturity Don’t plant under power

lines (PUD or yours) Don’t plant too close to

sidewalks, walkways, patios, foundations

Consider maintenance, leaf litter, smell

Page 17: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

CONSIDER WATER & CLIMATE

Does it need lots of water?

Don’t mix natives that expect dry summers in a irrigated lawn

Look for Zone 7 trees See County tree planting

list

Page 18: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

SHRUBS IN YOUR LANDSCAPE

Page 19: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

PRUNING SHRUBS Suggested Pruning Time

for Common Flowering Trees & Shrubs Summer-Flowering

Plants: Prune before spring growth begins (produce flowers on current season’s growth)

Spring-Flowering Plants: Prune after flowering (produce flowers on previous season’s growth)

Doesn’t Matter: evergreen hedge or unknown

Page 20: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

FIRE RESISTANT LANDSCAPING IT MAKES A DIFFERENCE

Page 21: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

THE BASICS OF FIRE RESISTANT LANDSCAPING

Determine your DEFENSIBLE SPACE zones and appropriate landscaping.

Remove DEAD or DYING vegetation. Break up CONTINUOUS vegetation. Eliminate LADDER FUELS. Make your defensible space LEAN (less fuel load) and

GREEN (watered where appropriate). Keep up with regular MAINTENANCE

Page 22: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

DEFENSIBLE SPACE

Zone 1: Home + 30 ft Zone 2: 100’ from house Zone 3: >100’ from house

Page 23: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

ZONE 1: STRUCTURE IGNITION ZONE

Most houses catch fire from embers, not flame front Clean gutters & roof “valleys” Get rid of dry grass, brush, flammable materials

(deck furniture, etc) around home & deck Woodpiles > 30 feet away Clear flammable materials away from propane tank Metal screens to keep embers out of vents and

metal window screens Enclose area under deck Less flammable plants, watered, “oasis zone”

Page 24: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM
Page 25: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

ZONE 2: FIREBREAK ZONE

30’-100’ from house Don’t have to eliminate

vegetation, just break up fuels and “fuel ladder” Reduce fuels Space trees & shrubs out Prune lower 6-10 feet of trees

Watered grass or gardens Gravel or paved breaks Again, less flammable plants

Page 26: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

USE LANDSCAPE MOSAICS

Page 27: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

ZONE 3: REDUCED FUEL ZONE

Zone 2 minimum 100’: more depending on slope & wind

Thin trees, reduce fuel ladder, reduce woody debris

Create a defensible space

Page 28: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

OTHER PRACTICAL CONSIDERATIONS

Post your address Mark USABLE water

sources with blue reflectors (check with VFD)

Meet CalFire requirements for turn-around and passing

Trim overhanging trees along driveway

Page 29: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

PLANT ZONES Compatible with

waterwise landscaping

High water zone - “Oasis” closest to home

Moderate water zone (i.e. lawn as buffer)

Drought-tolerant plant zone furthest from house

Page 30: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

BURN CHARACTERISTICS OF MULCH

Most to least combustible Shredded rubber Pine Needles Shredded Western Red

Cedar Medium Pine Bark

Nuggets Byproducts of chipper

(wood chips, bark, needles, other biomass)

Composted wood chips

CHOOSING PLANTS

Realize that plants are NOT fire- retardant; they can be fire-resistive.

Know your elevation and microclimate when making your plant selection. Healthy plants fare better.

Irrigation and maintenance are key factors in your choice of landscape plants.

Replace or eliminate flammable plants

Page 32: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

AVOID HIGHLY FLAMMABLE PLANTS

They contain fine, dry or dead material

Contain volatile waxes, terpenes or oils

Have aromatic leaves Loose or papery bark Sap is gummy, resinous

Examples: Artemisia, incense cedar, broom, juniper, pine, arborvitae, bay, Douglas Fir, manzanita, CA buckwheat, rosemary, dry annual grasses

Page 33: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

CHARACTERISTICS OF FIRE RESISTANT PLANTS

Moist & supple leaves Tend not to accumulate dry, dead material within

plant Sap is water-like and does not have a strong odor Sap or resin materials are low Influenced by plant age, moisture content, total

volume

Page 34: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

FIRE RESISTANT TREES

Fruit Trees Maple Oak Catalpa Ash Sweetgum Locust Hackberry Smoke Tree Redbud

Use deciduous trees, not conifers

Page 38: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

MAINTENANCE IS CRUCIAL FOR FIRE-SAFE LANDSCAPING

Simple, well maintained landscapes are safer than elaborate landscapes that are neglected.

Prune deadwood from beneath ground covers and shrubs.

Remove fire (fuel) ladders.

You’ll improve appearance and maintain safety at the same time.

BENEFITS OF GROWING NATIVE PLANTS

Adapted to our environment Use less water No fertilizer necessary

Enhance the soil health Promote indigenous bacteria, fungi, earthworms, and

other underground benefactors Low maintenance Encourage birds, beneficial insects and pollinators.

Page 42: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

KEYS TO GROWING NATIVES

Get to know your plant communities Know where the plants come from and what

conditions will make them thrive

Understand your site conditions Soil Sun exposure Water availability

Choose plants to suit your site

Page 43: Principles of Landscape Designcetrinity.ucanr.edu/files/259199.pdf · 2017. 3. 22. · Principles of Landscape Design Author: Carol Fall Created Date: 3/22/2017 10:56:20 AM

SUBSTITUTE NATIVES FOR TURF?

•KILL GRASS to start

•Stop watering •Mow short before going to seed •If seeding, collect clippings •Turn under, if possible •Water to germinate seed bank and repeat above steps

•Sow native seed mix

•Water and mulch Example - Tomcat Clover (Trifolium willdenovii), Bicolor Lupine (Lupinus bicolor), Yarrow (Achillea millefolium), Squirrel Tail (Elymus elymoides)
