Tall Fescue

Tall Fescue

Lolium arundinaceum (Schreb.) Darbysh.
(Formerly Festuca arundinacea Schreb.

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:

The Fine Fescues

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.

Low Maintenance Turf?

Low Maintenance Turf?

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.

NTA Final Report June 9, 2009

Purpose

By using balanced NPK + micros applied at a low rate (3.25 lbs N/1,000 sq ft/yr) or a high rate (6.5 lbs N/1,000 sq ft/yr), we are trying to determine if total annual NPK with or without added calcium, sulfur, or humates has any measurable impact on putting green turf quality, Microdochium patch disease, anthracnose disease, and/or turf species composition.

Introduction:

Fertilizing Lawns

Fertilizing Lawns

Explains how to optimize a fertilization program for a home lawn. Discusses how to select and use fertilizers, the roles of various elements (nitrogen, phosphorus, potassium, sulfur, pH, calcium, magnesium, and iron) in lawn fertilization, and the value of soil tests for each element. Provides sample calendars of necessary and optimal times for fertilizer applications for western, central, and eastern Oregon.
