Preparing and Seeding
a Turf Area
OBJECTIVE
The objective of this exercise is to properly plan, prepare,
and seed a turf area.
TEXTBOOK REFERENCE
Information related to this activity can be found in the
Landscape Construction textbook in Chapter 38, Estab-
lishment of Turf and Meadows.
INTRODUCTION
Several methods are available to install turf in the land-
Site Preparation
Site preparation is critical in establishing any seeded
area. Begin by clearing the site of any debris and peren-
or sandy loam soils 4–6 inches deep. Any amendments
needed to achieve this soil type should be added at this
point. Blending a starter fertilizer with the ratio of 1:1:1
(e.g., an 8:8:8 or 16:16:16 grade fertilizer) into the topsoil
be in place before the planting operation begins. The
edgers can be installed before grade preparation, but in
many cases the grade preparation may damage materials
already in place.
Installation of Plant Material
Based on the climate, seeding operations may be limited
to seasons where the chances for seed success are the
highest. In warm climates, seed can be applied to a site
at any time of the year, but in colder climates the best
Seeding
Seed application can be accomplished by hand sowing,
using a drop spreader, or using a broadcast spreader.

EXERCISE DESCRIPTION
To complete this exercise, clear a 30 foot × 30 foot area of
debris and plant material. Plan for the seeding operation
by determining if any amendments are required and cal-
culating the amount of seed, amendment, and fertilizer
required. Prepare the area for seed as instructed in this
