A Quick Review of Common Cool Season Grasses for New Jersey
Kentucky Bluegrass
Has great texture, density, color.
Tolerates heavy traffic.
Can require higher than average inputs of water, nitrogen, etc.
Has a rhizome structure, so does not tolerate drought well.
Somewhat slow to establish from seed.
Has a medium to high tendency to produce thatch.
Fine Fescues – see http://www.rce.rutgers.edu/pubs/pdfs/fs688.pdf
Low maintenance – require 40-50% less nitrogen than Kentucky Bluegrass.
Tolerate shady conditions.
Endophytic (beneficial fungus) varieties that resist pests are available.
Fine grass blades.
Hard Fescues – a variety of Fine Fescues see http://www.rce.rutgers.edu/pubs/pdfs/fs688.pdf
One of the best choices for low maintenance lawns in N.J.
Slow growing, so requires less mowing.
Require less fertilizers.
Need less water.
Excellent pest & disease resistance.
Medium tendency to produce thatch.
Turf-Type Tall Fescues -- http://www.rce.rutgers.edu/pubs/pdfs/fs990.pdf
Drought resistant, deep roots.
Endophytic varieties resist pests.
Fine leaf blade.
Ability to tolerate heavy traffic.
Newer varieties are useful for low maintenance turfgrass areas.
Low tendency to produce thatch.
Perennial Ryegrass – see http://www.rce.rutgers.edu/pubs/pdfs/fs989.pdf
Rapid establishment.
Great for over-seeding.
May require greater than average mowing.
Susceptible to Red Thread disease.
Not drought tolerant.
Grow poorly in wet areas.
Low tendency to produce thatch.

What to Do With Your Grass During a Drought
If water restrictions are in place you should not water your lawn.
Allow turfgrass to go into dormancy.
• Dormancy will protect grass from damage.
• Infrequent, inadequate watering will drain stored resources from dormant turfgrass.
Stay off lawn to prevent damage.
Do not use fertilizers during a drought or on heat-stressed turfgrass.
What Weeds Tell Us
Problem / Appearance/Symptoms / Cause / Solutiondandelion / familiar perennial plant with yellow flowers / compacted soil and thin turf cover / aerate soil; hand pull at least 80%; overseed with ryegrasses
crabgrass / low-growing annual with shallow roots and short, pointed, hairy leaves / nutrient-deficient soil, short mowing and soil compaction / raise mowing height; hand pull and apply organic fertilizers
common plantain / low-growing perennial with wide oval leaves / thin turf cover and low nutrients in soil / handpull; apply organic fertilizers and overseed
chinch bug / brown or yellow patches, particularly near driveways and sidewalks / stressed or weakened grasses caused by soil compaction and shallow watering / water deeply once a week; apply diatomaceous earth; dethatch and apply soap and water every 10 - 14 days
white grub / spongy dead patches that lift easily; common in spring and again in late-summer to early-fall / compacted soil, dry sunny lawns with short, weak roots, chemical fertilizer use and short weak roots / dethatch; water deeply; apply organic fertilizer; use soap and water or parasitic nematodes for major infestations; over- seed with ryegrass and fescues
dollar spot / small pale circles / dry soil and nitrogen deficiencies / add organic material; mow infected tips and discard clippings
summer patch / dead patches then brown rings; during humid summers / high nitrogen and low mowing / mow higher and apply organic fertilizer
Alternative Pest Control
"IPM approach" means an integrated pest management approach which employs a hierarchy of monitoring, cultural, biological (including natural enemies), and chemical controls.
