Creating a Sustainable Landscape What You Can Do? The 2015 University of California Master Gardeners of Yolo County Display Garden illustrates many elements of a sustainable landscape to give you ideas and motivation to create a home landscape that is attractive, appropriate for our climate, and fits the conditions of your location while using a minimum of resources. Resources like water or fossil fuels as well as the valuable resource of your time. We want to show you how to be good stewards of our environment and do all that you can to ensure that we have a healthy, well-functioning ecosystem for ourselves and for future generations. Incorporating sustainable practices into how you design and manage your home landscape is something that you can do. Because you work on your landscape over a period of time, let’s look at both the short term and the long term to create a sustainable landscape. Short Term Sustainable Landscape Goals:

Reuse Green Waste—Create compost and mulch

Right Plant, Right Place—Select plants that are appropriate for your location

Save Water—Use the right plants, reduce irrigated turf and prevent runoff

Recycle & Reuse—Use reusable materials for your landscape like used bricks, tiles, or broken concrete

Long Term Sustainable Landscape Goals:

Improve the permeability, aeration, and drainage of your soil

Get a soil analysis to determine the needs for your situation. Use only the fertilizer and soil amendments that are necessary

Enhance plant diversity in the landscape to discourage plant pests and provide habitat for beneficial insects and birds

Our 2015 Display Garden—Reduce, Reuse, Recycle—is full of ideas that we hope will inspire you to take steps toward your own more sustainable home landscape.

Features of a Sustainable Landscape:

Permeable Paving - allows rain to soak into ground instead of running off

Rain Barrel - allows for collection and reuse of rain that falls on roof

Rain Garden - allows rain water to soak into ground instead of running off

Dry Creek - channels water from downspout to rain garden

Hedge Wind Break - breaks intensity of strong prevailing winds

Mulch - reduces moisture loss, keeps soil cooler, suppresses weeds

Drip irrigation - directs water only where needed, minimizes loss due to evaporation

Deciduous Shade Tree - shades house from afternoon sun in summer, allows sunlight through in winter

Alternatives to Lawn - Use less water, provide color, interest, and sources of food for butterflies, birds and bees

Reduce Runoff and Save Water

Creating a sustainable landscape that saves water is more just watering your plants

less. A sustainable landscape saves water and prevents runoff by:

Using the right plant for the climate and location

Reducing high-water plants like turf

Watering efficiently with the best irrigation practices

Using permeable materials for walkways

Creating rain gardens and bioswales

Capturing rainwater with rain barrels

Rain Gardens

A rain garden is a shallow, constructed depression that is planted with deep-rooted

native plants & grasses. It is located in your landscape to receive runoff from hard

surfaces such as a roof, a sidewalk and a driveway. Rain gardens slow down the rush

of water from these hard surfaces, hold the water for a short period of time and allow it

to naturally infiltrate into the ground.

A rain garden can be thought of as a personal water quality system because it filters the

runoff from your roof and lawn and recharges the groundwater.

A rain garden also conserves municipal water resources by reducing the need for

irrigation.

Rain gardens are a beautiful and colorful way for homeowners, businesses and

municipalities to help ease stormwater problems. There is a growing trend by

municipalities and homeowners to incorporate natural processes to help relieve flooding

and pollution.

Benefits of Permeable Surfaces in Sustainable Landscaping

What is a permeable surface? What is an impermeable surface?

Permeable surfaces (also known as porous or pervious surfaces) allow water to

percolate into the soil to filter out pollutants and recharge the water table.

Impermeable/impervious surfaces are solid surfaces (often driveways, patios, and

walkways) that don’t allow water to penetrate, forcing it to run off.

The more impervious surfaces on a site, the more runoff there is. The consequence of

runoff is an increased speed of water flow, which cannot be absorbed into the ground as

readily, increases erosion, and dumps an excessive amount of pollutants into one spot.

Also, due to the heat-absorbing quality of some materials, sites with high ratios of

impermeable surfaces increase the surrounding air temperature. For this reason,

incorporating more permeable surfaces can create a cooler area.

What are examples of permeable surfaces?

Planting beds

Mulched beds

Bark or walnut hulls

Sand/Crushed stone/Gravel

Brick/Stone with gravel or planting in between

Permeable pavers

Turf

Creative ways to use permeable surfaces:

Replace solid driveways with porous alternatives, or use impervious paths for the

car with green plant materials in between. Solid concrete can also be broken up

with decorative and functional paver inlays.

Use pervious concrete, a cement-based concrete product that has a porous

structure allowing rainwater to pass directly through the pavement and into the soil.

Design using green spaces between hard spaces and be sure to grade paved

areas towards the planted areas.

Interrupt walkways with small planting beds and creeping groundcovers such as

thyme to help slow storm water flow and create a more aesthetic space.

Green walls - Build small out-pockets and planters on the sides of retaining walls.

These are visually interesting and will help absorb water and reduce runoff.

Examples of permeable surfaces:

Rainwater Catchment Systems

A water catchment system collects rainwater from a large, hard surface, such as a roof.

Water travels down the roof, into the downspouts which are connected to some type of

container, such as an enclosed barrel or cistern. The water is then saved for future use.

Over time, water catchment systems make an impact. The average 1000 square-

foot roof collects approximately 600 gallons of water during a 1-inch rain.

It is important to remember that the collected water is considered non-potable and

should only be used for watering non-edible plants or washing your vehicle.

Rainwater catchment systems range from simple to complex. A plain barrel or container

serves a small area. More complicated versions incorporate filters that clean the water,

connections to irrigation equipment and even pumps. Most barrel-type systems

incorporate a hose connection to allow for easy watering.

Reduce Yard Waste and

Use Recycled Materials

Deal with yard waste in a sustainable way. Instead of sending it to the landfill, reduce

the amount you create and recycle and compost what you can.

Reduce Yard Waste

Select the right plant for your landscape to reduce pruning.

Weed often so weeds are small.

Apply 2 to 4 inches of mulch around plants to prevent weeds.

Use a mulching lawn mower instead of collecting lawn clippings.

Compost

Compost turns yard waste, food scraps, shredded paper and leaves into rich soil

that enriches your plants.

Compost saves water by retaining moisture and reducing runoff.

Compost reduces landfills.

Recycle, Upcycle, Repurpose

Recycle plastic pots and nursery flats.

Return nursery flats to the nursery.

Use sticks and branches as plant supports.

Cans, egg cartons, yogurt containers make great seed starters.

Turn old hoses into bucket handles, earwig traps or stake covers.

Get free 5-gallon buckets from restaurants, bakeries and grocery stores.

Landscape in Harmony

Right Plant, Right Place

Select plants that are appropriate for your location. Plants that do well in Yolo County

require less water and less work, can withstand high winds, and provide habitats for

beneficial insects and birds. Choose the right sized plant to fit the space. Also planting

in the best location can create windbreaks and shade, ultimately lowering energy use.

Right Plant

Choose waterwise or drought-tolerant plants that thrive in Yolo County.

Select native California plants.

Plant a variety of plants, which can provide habitats for beneficial insects and

reduce damage from diseases.

Reduce turf and replace with waterwise plants or permeable surfaces.

Right Place

Plant shrubs and trees that are the right size for the space.

Plant large deciduous shade trees on the east, west and southwest sides of the

house. Avoid planting them directly south of the house where they will block

winter sun.

Shade air conditioning condensers for more efficient operation.

Plant trees and shrubs to block the wind.

Waterwise Container Gardening

Generally container pots need to be watered more frequently but they can be an

appropriate choice for a sustainable landscape.

Choose waterwise plants.

Mulch pots with moss or wood chips.

Use drip or micro spray irrigation to efficiently and effectively water containers.

For large pots use irrigation bags.

Consider putting containers in the shade and use shade tolerant plants to reduce

water use.

Use gray water to water containers.

Reduce Harm to Habitats

We sometimes think that all insects are enemies, so use chemical fertilizers to encourage

growth and poisons to kill pests. Unfortunately, most are indiscriminate and kill beneficial

organisms, too, upsetting the natural balance, and, when it rains, the chemical runoff

poisons our groundwater, rivers and bay. Using Integrated Pest Management (IPM)

methods is a better way to control pests and keep a healthy, natural balance in your

garden. IPM techniques can be as simple as planting companion plants to attract

beneficial insects, picking harmful insects off plants or spraying them with water.

Friends You Should Invite Into Your Garden!

Ladybugs — This aphid loving beetle is worth its weight in gold.

Lizards — Alligator lizards will search dark basements, garages and bushes for their favorite meal – black widow spiders.

Spiders — The average spider eats about 100 insects a year.

Toads — One toad can eat between 10,000 and 20,000 slugs, flies, grubs, cutworms or grasshoppers per year.

Bats — Besides being a valuable pollinator, bats consume large quantities of insects. A single little brown bat can catch 600 mosquitoes in one hour.

Bees — In California alone, forty-two different nut, fruit, vegetable, forage and seed crops rely directly on bee pollination.

Green Lacewings — Green Lacewings will eat mites, mealy bugs and other small insects but their favorite meal is aphids.

Ground Beetles — Ground beetles' favorite insect meals are cutworms, grubs and root maggots. Some even love slugs and snails. To invite them into your garden, place a log or board at one end of your garden.

Hover Flies — These flies look like little flying helicopters. They feed on flower nectar, which makes them excellent pollinators. Their favorite meals are aphids and mealy bugs.

Hummingbirds — These small birds consume more than half their total weight in food.

Creating a Pollinator Garden

When you look at a flower, how often do you consider the importance of these unsung

heroes? Pollinators help produce beautiful landscapes and the bounty of fruits, nuts and

vegetables we all enjoy.

Bees, wasps, flies, butterflies, moths, beetles, birds and bats help plants reproduce by

carrying pollen from one flower to another.

Right now, honey bee and other pollinator populations are being threatened by a

number of factors including disease, mites, and loss of habitat and food sources.

Three-fourths of the world's flowering plants depend on pollinators, and those pollinators

need your help!

Have you seen bees and other pollinators in your own neighborhood?

Are there flowering plants in your garden, park, school or community?

Did you know that many pollinators are essential for the production of most of the

fruits and vegetables you eat every day?

Things to Consider for your Garden:

A variety of plants will be ideal for providing diverse sources of nectar and pollen.

Choose at least 20 different plant types, or fewer if the types of plants are highly

attractive to pollinators. Don't forget that night-blooming flowers will support

moths and bats.

1. Help pollinators find and use your garden by planting in clumps, rather than

just single plants. Think about "landing zones."

2. Include plants native to your region. Natives are adapted to your local climate,

soil and native pollinators. If you want to see some locals, plant some natives!

3. Overlap flowering times between seasons and use a wide variety of plants

that bloom from early spring into late fall. Pollinators are in a constant search for

new resources. Choosing plants with overlapping flowering times from February

to October will allow bees and pollinators to continually forage in your garden.

4. Consider plant climate zones. Plant for success! A plant's native climate range

is important in determining if it will be attractive to bees visiting your garden (and

if your plant will grow well in your garden or not!).

5. Design a garden that has structure. The arrangement of plants in your garden

will influence your ability to observe and enjoy pollinators. Plant the tallest plants

in the back with the smaller ones in the front.

6. Plant in the sun. Bees prefer to visit flowers in the sun, so avoid planting your

pollinator-attracting plants in the shadier parts of your garden.

7. Reduce or eliminate pesticide use in your landscape, or incorporate plants that

attract beneficial insects for pest control. If you use pesticides, use them

sparingly and responsibly. Pesticides can kill bad insects as well as beneficial

insects like bees, ladybugs and other predators of garden pests.

8. Don't forget about nesting bees! Not all bees have a hive. Make sure to leave

some areas for bees to build their nests (either in bare ground or in prefabricated

cavities in wood). It's ok to leave part of your garden un-mulched for ground-

nesting insects to discover.

9. Leave dead tree trunks and branches in your landscape for wood-nesting bees

and beetles. By leaving dead trees, or at least an occasional dead limb, you

provide essential nesting sites for native bees, but make sure these are not a

safety hazard for people walking below. You can also build a bee condo by

Page 17: Reduce, Reuse, Recycle · Recycle, Upcycle, Repurpose Recycle plastic pots and nursery flats. Return nursery flats to the nursery. Use sticks and branches as plant supports. Cans,

drilling holes of varying diameter about 3 to 5 inches deep in a piece of scrap

lumber mounted to a post or under eaves.

10. Provide clean water for pollinators with a shallow dish, bowl, or birdbath with

half-submerged stones for perches.

11. Create a damp salt lick for butterflies and bees. Use a dripping hose, drip

irrigation line, or place your birdbath on bare soil to create a damp area. Mix a

small bit of salt or wood ashes into the mud.

12. Provide a hummingbird feeder and add to nectar resources. To make

artificial nectar, use four parts water to one part table sugar. Never use artificial

sweeteners, honey, or fruit juices. Place something red on the feeder. Clean your

feeder with hot soapy water at least twice a week to keep it free of mold.
