Utility Groundcovers

Slide 2

What kind of scenarios might dictate a groundcover that isn’t one of the 4 turfgrasses we’ve learned?

Slopes for Erosion Control

Green Roofs

Ditches (and other utility areas)

Native / Reclaimed plantings

manmade meadows

true reclamation projects

Low Maintenance Landscape designs (consider bunch type grasses for an Oriental garden feel).

Slide 3

Low Maintenance Groundcovers

Features:

Occasional mowing

No watering

No fertilizing

Characteristics:

Drought tolerance

Speed of establishment

Root type

Widely adapted soil preference

Rate of spread

Speaker Notes

  • Reclamation species of grass for low maintenance areas
  • Reclamation – usually rough work with large equipment
  • Usually maintained under low to zero conditions…occasional mowing, no watering, no fertilizing,
  • Looking for drought tolerance, root type, soil preference, speed of spreading

Slide 4

Low Maintenance Grasses…

The Non-Fescues

image3.jpg

Speaker Notes

  • Photo credit: E. Wheale 2015
  • There are lots of grass options out there other than the 5 species we have looked at, and some of these grasses are even making their way into lawn blends, not just utility blends.
  • Some of these are native grasses, some are introduced pasture grasses, and some are custom utility blends specifically for erosion control or another purpose, but be wary of those as they may be hyper aggressive growers.

Slide 5

Telling these grasses apart...

image4.png

Speaker Notes

  • These grasses are a lot of the classic “ditch” grasses that grow wild in Alberta.
  • Because the purpose of this class is TURF management, we are not going to get into vernation, ligule, etc. BUT it is worth noting when plants are in the same genus as ones we’ve learned already.
  • In addition, it is fairly easy to tell them apart when you see their inflorescence. Take note of the differences between them… as well as where they are especially good at growing, and which ones are INVASIVE in natural areas.

Slide 6

28 Poas are tracked in Alberta Conservation Information Management System

Canada Bluegrass - Poa compressa - Non-Native!

Adapted to infertile, poorly drained soils

Very winter hardy

Familiar Genera - “low maintenance blends”

Fescues are common as well

15 are native, including F. rubra

Most of what we use are introduced (Tall, Chewings, Sheeps, Meadow)

image19.png

Slide 7

Many ornamentals are natives

Pay attention to growth habit/reproductive tillering

is it actually low maintenance?

Is it warm season or cool season?

Other Grasses (Front Lawn/Garden hybrid design)

http://photobotanic.photoshelter.com/image/I0000mk_9OjacAa8

image5.png image9.png

Speaker Notes

  • Bottom left is blue Grama grass, a native that can be nicely clumped, but look in the upper left corner - it will spread.
  • Bottom right is ribbon grass (phalaris genus) it is incredibly invasive in ornamental gardens!

Slide 8

Commonly used as Pasture Grass

Excellent for erosion control

Do not use adjacent to natural areas unless you KNOW it is native! (very difficult to control) - these are some that are classed as “invaders”

Agricultural/Ditch grasses

Bromus - Smooth Brome

Agropyron - Crested Wheatgrass

Phleum - Timothy

Agrostis - Red Top

image26.png image2.png image1.png image22.png image16.png

Speaker Notes

  • https://open.alberta.ca/dataset/56928e5c-cb66-42cb-a348-8736d387e752/resource/98b66cad-44ea-4a95-86f2-9ca5decc3274/download/134-06-may2016.pdf
  • Bromus inermis:
  • Very drought tolerant, needs little water or fertilizer, well suited for hillside reclamation, Will tolerate some mowing, Spreads by seeds,
  • Agropyron cristatum:
  • most drought tolerant non-fescue reclamation grass; excellent for zero maintenance, adaptable to a wide range of soil types; good for hillsides, slopes, erosion prone areas; also spreads by seeds and can be very invasive in natural/native areas. It was planted in Kananaskis in a native planting area and soon took over. It has caused a lot of outrage and a control nightmare now trying to remove it from the area it doesn’t belong.
  • Agrostis alba
  • Originally came from Europe. Used in pasture mixes under humid conditions but is low in palatability. A sod forming, develops rapidly from seed and establishes well in moist soils, along roadsides and on open ground. It is often used for erosion control until slower-growing grasses become established. It is rarely seeded alone.
  • Phleum ssp. or Phleum pratense
  • Used for soil stabilization projects, road side seeding, streambank reclamation. Tolerates some mowing, prefers moist humid and full sun, good forage

Slide 9

Agricultural/Ditch grasses

Foxtail Barley

Weed - animals cannot eat it

Bunch type, spreads via seed

Alkaligrass

Moist, saline soils

Sod forming

image14.png image15.png

Slide 10

Native in Alberta and/or introduced

Attractive inflorescence or foliage

Good for low - no mow boulevards and island beds

Be sure to contain them!

“Mat forming” vs “Clumping”

Ornamental grasses

Bouteloua - Blue Grama

Phalaris - Ribbon Grass

Koeleria - Junegrass

Deschampsia -

Tufted Hair grass

image30.png image35.jpg image38.png image11.png

Speaker Notes

  • Blue Grama - Native in Alberta - Mat forming - erosion control and highways
  • Ribbon grass - pretty red hue in the Fall - but VERY invasive - thick white rhizomes.
  • Tufted Hair Grass - species is native to Alberta

Slide 11

Low Maintenance Legumes

Compensate for poor quality soil

Root system contains bacteria that form nodules

Capable of fixing free nitrogen

Intolerance to herbicides (2,4-D)

Alfalfa

Crown Vetch

Bird’s Foot Trefoil

image17.png image12.png image13.png

Speaker Notes

  • When legume dies after 3-5 years its root system breaks down in the soil providing nutrients and organic matter which help to improve the soil structure
  • Downside – intolerant to herbicides – very sensitive so would be affected if spraying for weeds
  • Alfalfa - Very drought tolerant, Highest nitrogen fixation of all legumes, Will tolerate occasional mowing, Smells nice
  • Crown vetch - Penngift is an attractive, perennial, ground cover. Crown vetch can be an invasive plant and should NOT be planted in lawns or crop areas. It is difficult to remove once established. This plant item is intended for use in certain situations such as for erosion control in difficult to access hillsides, certain wildlife plantings, ground cover plantings, etc. During the flowering season, it is a heavy producer of white, pink, and lavender flowers. It is a creeping plant with semi-vining growth habits which produce considerable foliage that grows up to 18 - 24 inches. It is very competitive and will crowd out most weeds with time. It develops an extensive root system to make it drought tolerant. It is used primarily for roadside seedings and for landscaping hillside erosion where a low-growing perennial flower is desired that doesn't need mowed. Crown vetch is also used for wildlife foraging such as a deer food plot. Because crown vetch is slow to establish, a companion crop of creeping red fescue or annual ryegrass at 1 pound per 1,000 square feet provides initial cover. A rough, cloddy seedbed is satisfactory.
  • Bird’s foot trefoil - Tolerates very poor soils & wide pH range, and poor drainage. Heat-resistant. Salt-tolerant. Attractive yellow flowers. Seed (with inoculant), crown division, or cuttings Can seed with ryegrass or oats. May be mowed. Available.

Slide 12

Clover

Low N fixation

long lived seeds

Sweet flowers

Bee Turf plant

image7.png image10.jpg

Speaker Notes

  • Lowest potential for nitrogen fixation
  • Common ones used are white and red – this one is White Dutch clover
  • Well adapted to wet or dry soils
  • Thrives under regular mowing
  • Stoloniferous

Slide 13

Bee turf contains:

sweet alyssum (attracts predatory insects)

clovers (N fixer, pollinator)

fescues (low needs)

yarrow (native, pollinator plant)

English daisy (pollinator)

Roman chamomile (pollinator)

500g = 400 ft/square

Slide 17

Sedum Tiles (aka Sedum “sod”, or Sedum “turf”)

Sod - like product, or in tiles

Originally produced for green roof installation

As with legumes, susceptible to invasion by broadleaf weeds and rhizomatous grasses

Should be hardy in prairie climates if purchased from prairie grower.
