For the purposes of lawn
maintenance -and care, the
groWing season from April
ay It
divided into three main
pericids. The division of the
growing season is not exact,
so maintenance -practices
may overlap, Lawns and
lawn problems differ con-
siderably. Not all lawns have
the same problems. It is
important to know your soil
type and have it tested for
nutrients.
The maintenance prac-
tices suggested in this article
are for a typical kentUcky
bluegrass lawn in full sun,
with a Kentucky bluegrass-
red fescue mixture inshaded
areas, .as a loam soil. It is
also assumed that a tnediurn
to " high visual quality is
required,
April -May
Raking - A vigorous raking
with , a leaf rake, as_scion, as
the turf is dry enough to walk
on, .will remove many
creeping bent grass and
rough bluegrass stolens. It
will also help dry the lawn,
and reduce snowrnold fungus
activity.
Thatch control - Thatch
consists of a tightly in-
termingled layer of living
and dead Stems, leaves, and
roots, that develop at' the soil
surface. Thatch causes grass
- plants to develop above the
soil surface. Vigorous hand
raking in mid-to-late April, is
effective for thatch removal
in small area. However, for
larger area s„,,imechanical
removal is more toractical.
Rolling Tprf areas seeded
the previous fall should be
rolled to press the grass
plants back into the soil.
Rolling can also be used to
level the lawn, but it may
cause unacceptable com-
paction On fine-textured
soils.
Fertilization - Apply a
complete fertilizer of a 4:1:2
(N: P:K) ratio with .a fast-
release nitrogen carrier
(water-soluble nitrogen) at a,
rate of 0.5 kilograms actual
nitrogen per 1.00 square
metres (1 ..pound N-1000
square feet).. Nitrogen
provides early shoot growth
and green color and should
not be applied earlier than
mid-April.
Weed Control - Annual
grass weeds, such as
crabgrass, can be controlled
with' a pre-emergent her-
bicide, such as Bensulide or
dacthal, applied late April.
Broad-leaved weed control is
most effective in mid-
September. However, an
broad-leaved weeds,
such as prostrate knotweed,
and weeds which were
`missed the previous fall,

The numbers listed on
fertilizer bags, for example
5-10-15, refer to the per-
centage of the • three main
nutrients. The first number
is the percentage of nitrogen,
the second is the percentage
of phosphorus, and the third
number is the percentage of
potassium.

Early July is the best time
to. 'treat for hairy chinch
bugs. To check your lawn for
these pests, use a large juice

necessary.

Mowing Mow at a height
of fotir centimetres (11
inches), once every 10 days,
until late 'May, For heavy-
Slade areas, delay mowing

the turf has grown to a height

Then mow ncrlower than .6 to
7 centimetreS,-(21/2 inches).
Do not remove more than40
percent of the leaf blade
during mowing.
Cultivation - Fine-
textured, poorly-drained
soils and areas of Con-
centrated foot traffic may
require' coring er slicing, A
compacted Soil condition
restricts water and air
movement within the soil,
resulting in a shallow root
system and reduced quality.
In small areas, cultivation
can be accomplished with a
fork. A mechanical aerating
machine is required for
large areas,
Renovation Resodding is
much better than 'seeding at
this time of year, Spring
sown seed is slow to ger-
minate because of low soil
temperatures. The seedlings
do not grow well because of
intense weed competition.
Disease -The main disease
of home lawns in spring is
leaf spOt. Definite, dark,
purplish-red spots appear on
the leaf blades. It is im-
portant to control the disease
at this stage; If en-
vironmental conditions favor
disease development (cool,
-cloudy weather, h i gh
nitrogen, frequent low
mowing), root and stem rot
will develop in June. To
control this disease, apply a
fungicide, such as Daconil or
Dyrene, raise the mowing
height, and reduce the
mowing frequency for
several weeks. ,
