Lawns

Introduction:

For as long as golf has been played in the Pacific Northwest creeping bentgrass has been planted on putting greens, first as a component of South German mixed bentgrass, and later as seeded or stolonized varieties. In recent years, intense breeding and selection work has resulted in a flood of new cultivars with widely varying characteristics and generally much improved surface quality. While early creeping bentgrasses quickly gave way to annual bluegrass, newer cultivars are much more competitive and may prove to be much more persistent.

Introduction:

Tall fescue is probably the most widely planted cool season grass in the world. This guide will cover botany, history, cultural requirements, and strengths and weaknesses of this fascinating grass.

Botanical Characteristics and Identification:

Festuca sp.

Introduction:

The fine fescues are composed of several different Festuca species and subspecies. All are fine textured compared to most other commonly planted turfgrasses. Fine fescues have long been used in mixtures with other grasses and are generally considered the standard for shade tolerance in cool season grasses. In recent years, the fine fescues have received attention as low input environmentally sustainable grasses. Most retail lawn mixtures contain at least some fine fescue.

Botanical Characteristics:

Lolium perenne L.

Introduction:

Poa pratensis L.

What is a low maintenance lawn? Who sets the standards? An honest answer to both of these questions is probably "I don't know". By my standards most people in western Oregon already have low maintenance lawns. Their lawns are mowed sporadically in spring, occasionally in summer and fall and not at all in winter. A clear majority don't irrigate at all and of those who do, few irrigate consistently. Perhaps seventy percent of these homelawns are never fertilized and very few are ever treated with herbicides for weed control. Sounds pretty low maintenance to me.

As I drove into campus this morning, I noticed several sprinkler systems running.  After a week of on and off rain, day temperatures in the 70s and night temperatures in the 40s, it is time to reduce watering times and/or days or even better, turn the irrigation system off.  The turf is using very little water this time of the year and it will allow the turf to naturally harden off as the winter months approach.  An additional benefit of turning your irrigation system off is that the lack of moisture will greatly reduce the survivability of European Crane Fly eggs.  So, turn the irrigation

Previous work reported by Crystal Fricker at Pure Seed Testing Inc. demonstrated that it is possible to develop tall fescues and fine fescues that have relatively good tolerance to low rates of glyphosate. This trial is part of an ongoing effort to evaluate tolerance of tall fescues and other grasses to glyphosate at rates that are effective in controlling annual bluegrass.
