3LAWN
- Lawn is beautiful green ground cover with
perennial grass. - Also called as a natural green carpet.
- A lawn is the heart of a garden.
- It is the basic feature for home ground
development - In home garden
- improves the appearance of the house,
- enhances the beauty,
- Increase conveniences
- It adds monetary value to the real estate
4- Lawn also provide
- Perfect setting for
- flower beds
- A border
- A shrubbery
- A specimen of tree or a shrub
- Besides ,
- the lawn has spiritual value too
- Lawn is source of charm and pride
- reduces tension of mind after a days hard work
5IMPORTANCE.
- Lawn is one of the most important features of a
garden - Without a lawn no garden is complete and
beautiful as the beauty of the garden largely
depends on the condition of the lawn. - Main point of attraction of the garden.
- Provides a place for takings rest after the days
hard work. - Ideal place for holding parties and different
Social functions.
6Characters' of lawn grasses
- It should develop quickly.
- The grass must have compact growth.
- It should withstand regular mowing.
- It should tolerate Cold and drought.
- The grass should be soft to touch and not patchy,
- Should not give fowl and bad odour
- Should look fresh and remain green throughout the
year.

8SITE SELECTION
- The selected site for making lawn should get full
sunlight and the best situation is the southern
side of the house. - The site selected should be in south-east or
south west direction of house or any building. - Lawn grass do not grow well under the shade.
9- More over,
- The dried leaves of trees fall on the lawn grass
make the lawn dirty, hence it is desirable that
no big trees should be existing in the site
selected - Trees selected should provide shade during summer
for sitting and should not shed leaves without
adversely affecting the lawn - Soil moisture capacity and drainage are very
important - Poor drained soil- grass will perish
- Highly porous soil- Frequent irrigation
10SOIL
- For establishment of a good lawn fertile loamy
soil is ideal. - Soil should be rich in humus content.
- It should have good moisture holding capacity and
at the same time it should have good drainage - Depth of soil shold be at least 25-30 cm for
luxuriant growth
11SOIL
- A slightly acidic soil having pH between 5.5 to
6.0 is good growth of grass. - Low pH-½kg/m2 of chalk or grounded lime stone
- Alkaline soil- Gypsum- ½kg/m2
12Drainage
- Selected site- proper drainage
- Grasses are shallow rooted herbs and no deep
drainage is necessary, but - No water should stagnate in the root zone
- Clayey soils- Drainage pipes or by putting a
layer of bricks and rubbish 90cm bellow the
surface - Ordinary drainage carried out with grading and
levelling
13Drainage..
- Rough surface leveling by eye estimation- prior
to digging - Shifting and filling of soil done if necessary
- After rough levelling- thorough preparation of
land is necessary- by digging - Very often digging- contribute to the failure of
lawn - Digging should be done by trenching method- other
wise the gardener fail to dig to the desired
depth - To ensure proper depth- trench of 60cm deep and
45 cm width dug at one side of the site
14Drainage
- During digging- old masonry, grass roots, stones
etc., should be removed - Special care should be taken to remove the roots
of Motha grass (Cyperus rotundus) - Digging should be done during April
May-sterilize the soil, kill weed seeds, insects
and harmful micro organisms - Soil should be turned up subsequently 2-3 times
at weekly intervals, - each time clods of earth,
if any are broken and roots of weeds are removed
15Manuring and Grading
- After digging is over,
- Soil is manured and graded
- If the soil is already fertile- Dont apply
organic manure- weed seeds - Poor soil-FYM, night soil manure, stable
manure-500kg/100 m2 - The manure is worked up to a depth of 15-20cm
- Any freshly dug soil will take long time for
settleing - In heavy rainfall areas- soil get settled due to
pouring rain - In low rainfall areas- flooding is done to notice
the depression and filled with soil and finally
leveled using spirit level
16Selection of grasses
- Most suitable in India- Hariyali- Doob grass
Cynodon dactylon

withstand heavy use during the spring, summer,
and early autumn months when they are actively
growing,
19Bermuda grass (Seeded and hybrid species)
Cynodon spp.
- Identifying tips
- A medium to coarse-textured gray-green grass.
Leaves are folded in the bud. - Hybrids are more fine-textured and vary in color
from deep blue-green to dark green. - Bermudagrass loses its color and becomes dormant
in most locations during the cooler months of
late autumn and winter. - It spreads both by rhizomes and stolons.
20Bermuda grass (Seeded and hybrid species)
Cynodon spp.
- Maintenance

temperatures, - but it can tolerate drought conditions and high
temperatures. - Bermudagrass has a high tolerance for salinity.
21Bermuda grass (Seeded and hybrid species)
Cynodon spp.
- Planting and management tips for bermudagrass
- Mowing
- Mow short to produce neat, restrained turf.
- Mow frequently during warm months.
- Mow seeded bermudagrass at 1 - 1.5 inches both
rotary and reel lawn mowers can be used. - Mow hybrids at 0.5 - 0.75 inches a reel mower
should be used. - Fertilizing
- Fertilize using 2 - 4 lbs. nitrogen/1000 sq. ft.
per year during the period of active growth
(April - September) for seeded bermudagrass. - More attention is required for hybrid varieties
fertilize using 4 - 6 lbs. Nitrogen/1000 sq. ft.
per year during the period of active growth
(April - September).
22Bermuda grass (Seeded and hybrid species)
Cynodon spp.
- Planting
- Establish seeded bermudagrass from seed in areas
where adapted. - Seed at 1 lb. seed/1000 sq. ft.
- Establish hybrids vegetatively from sod, stolons
or sprigs (4 - 6 bushels/1000 sq. ft.), and
plugs. - Irrigation
- Water infrequently.
- Water deeply to develop a healthy root system.
- Avoid frequent, shallow watering.
- Special problems-
- Bermudagrass mite, Dichondra flea beetle, Fiery
skipper, Spring dead spot - Invasive
- Hybrid bermudagrass requires frequent mowing
- Dormant in winter

- St. Augustinegrass, along with bermudagrass and
zoysiagrass, is a warm-season turfgrass. In areas
where it is well adapted, it is water efficient
and has few pest problems. St. Augustinegrass is
used in the most moderate California climate
zones, along the Southern California coast or in
coastal valleys. It prefers full sun, but has a
high tolerance for shade. It grows quickly during
the summer months, but slows down during the
spring and fall and enters a dormancy period in
the late autumn and during the winter months.
Because St. Augustinegrass is not wear tolerant,
it is used for lawns and general purpose turf,
but not for high traffic sports turf. - Identifying tips
- A broad-bladed, medium-green grass. Leaves are
folded in the bud, there are no auricles, the
ligule is a fringe of hairs, and the leaf blades
are wide with a boat-shaped tip. The leaf sheath

node. It forms a dense prostrate turf that is
virtually weed free. - Maintenance
- Moderate maintenance. St. Augustinegrass requires
a high amount of nitrogen per year. It has a high
tolerance for shade and heat but a poor tolerance
for cold temperatures. It is drought and salt
tolerant. Thatch is a severe problem. If not
regularly dethatched, St. Augustinegrass can be
difficult to mow.

72- Land Preparation
- The germinated weeds during this period can be
easily removed before next watering spray non
selective type of herbicides paraquat/gramaxone(1-
1.5 lit /ha)800-1000 - After the soil has settled, level the soil by
filling depressions repeat rolling. - A gradual slope from the centre to the edges is
always preferred to facilitate drainage of excess
water during heavy rains and irrigation drainage. - In small lawns where the soil is not so sticky
necessary arrangement of drainage may not be
necessary.
73PLANTING OF GRASS.
- Planting of grass can be done at anytime of the
year. - But in the tropical country like India it is
better to start the work of planting the grass in
the beginning of rainy season, because grass
thus planted will get quicker growth and better
establishment..
74a KOREAN GRASS.
- This grass is native of Japan and Korea.
- It has recently been introduced in India
- Korean grass has velvety growth besides having
more tolerance to cold. - This grass is highly suitable for making lawn in
small areas and home gardens.
75b DOOB OR BERMUDA GRASS.
- It is used very commonly for making lawn due to
its faster growth, hardiness, less water
requirements. - This grass makes excellent turf.
- it can be grown on any type of soil.
76Method of planting Grasses
- Seed sowing
- Dibbling
- Turfing
- Bricking
- Turf plastering
- Planting on polythene sheet
771. SEED SOWING.
- Before sowing of seeds divide the entire plot.
- It should be 200 -300sq meter.
- 500 gm Of seed will be required for 200 sq metre
area. - The entire amount of seeds should be mixed with
double the quantity of fine soil. - Then the soil should be raked over in two
directions so as to mix the seeds uniformly with
the soil. - Then the ground should be rolled..
- Then watering must be done.
781. SEED SOWING.
- The seeds will germinate within 3-5 weeks.
- After few weeks when the grass attains the
height of about 4-5 cm the first cutting should
be done and then the surface is rolled. - The grass on the lawn should never be allowed to
grow more than 5 cm.
79(No Transcript)
802. DIBBLING.
- It is cheapest and slowest method of lawn making
but it is the most common method. - A small bunch of grass along with roots and
little stem is taken. - Planting is done at a spacing of 7-9 cm apart
both row to row and plant to plant, preferably
when the soil is slightly moist. - The roots spread and grow underground in the
course of 3-4 months making a fairly compact lawn.
813. TURFING
- It is also called sod method quickest method of
forming a lawn. - Small pieces of well prepared lawn or turf are
cut into square or rectangular shape preferably. - Turf is a piece of earth with compact grass on
it. Selected small piece of grass should be cut
uniformly thick selected from a place free from
weeds and grasses along with soil are placed on
prepared ground side by side closely - Slightly beat down flat into position.
- Any cavity or interspaces found should be filled
with fine soil. - It is the most costly way of making a lawn.

854. BRICKING
- It is done to replace few unhealthy patches in a
well maintained lawn. - In this methods pieces of lawn along with soil in
the shape of bricks are planted and watered
immediately.
865. Turf Plastering method
- Grass roots with little stem of 4-5 cm long
pieces are mixed with garden soil, fresh cow dung
water and roots i e., rhizomes or stolons of doob
grass. - Spread this paste evenly over prepared field
during raining season. - It is then covered by 2 cm soil and watered
regularly.
876.PLANTING ON POLYTHENE SHEET.
- In this method lawn is grown on thick
polyethylene (800 gauge thickness) - First cut the polyethylene into suitable pieces
of desired dimension. - Spread a mixture of soil (3-4 cm thick) over the
polyethylene sheets grow grass on it. - It can be rolled and taken when temporary effect
is to be created.
88Maintenance of lawn
- Once the lawn has established it needs
maintenance. - To retain of the texture of the turf and its
uniform colour, the lawn is raked, aerated and
top dressed with fertilizers kept weed free
since it is the focal point of any landscape
design an improperly cared or badly maintained
lawn can spoil the beauty of the complete garden.
89Maintenance of lawn
- Lawn rolling
- Mowing
- Manuring
- Scraping
- Raking
- Watering and
- Weeding
90 Rolling
- The purpose of rolling is to bring the grass in
contact with the soil and also to keep the ground
levelled - After the first shower of rain, roll, thoroughly
with medium roller both ways to make the level
correct. - Avoid rolling when the soil is too wet.
- The lawn should be rolled after every weeding or
at weekly intervals.
91Mowing
- Mowing is the process of cutting turfgrasses
using lawn mowers to improve aesthetics,
appearance of area, to provide a good playing
surface for a game and to control the weed growth
92Moving
- Moving is important operation to get good quality
and healthy lawn - Regular mowing of lawn is also as essential as
watering. - Moving frequency varies with season and type of
grass - Never allow the grass to grow more than 6 cm
high. - During winter the lawns require mowing once or
twice a week. - Mower Machine used for cutting grass or other
plants grow in the lawn
93- Mowing frequency The number of times a turf
grass community is mowed per week, month or
growing season - Mowing height The distance at which the ground
surface at which the turfgrass is cut during
mowing - Mowing interval The reciprocal of mowing
frequency is mowing interval i.e., the number of
days, week etc., between successive mowing - Mowing pattern It is the pattern of back and
forth travel while mowing turf. Pattern may be
changed regularly to distribute wear and
compaction to avoid creating grain and to
create visually aesthetic effects, especially for
spectaror sports

98Top dressing and manuring
- For continuous and healthy growth of lawn
continuous supply of nutrients is important. - FYM -100kg/ 100m2
- Bone meal-1kg/10m2
- The application of 50gms mixture/sq.mt during
rainy season (August September) Feb-March
helps to maintain a good growth of grass. - The mixture will contain 2 parts CAN, 1 part SSP
and 1 part of potassium sulphate. - Spraying of urea _at_2g/litre of water is also
useful to produce good growth of grass. - A top dressing of garden soil course sand and
screened leaf mould with addition to bone meal in
121 proportion should be applied followed by
raking and scraping. A quantity of 100kg to
cover an area of 100 sq.mt to a depth of 2 cm is
sufficient, - It can be repeated for every 2-3 weeks.
99Scraping and raking
- Scraping and raking are always beneficial to
maintain the tenderness of the lawn. - Due to constant rolling and mowing a hard crust
forms on the surface and lower part of the grass
become woody. - Before rainy season that is May or June the
entire lawn should be scraped completely with a
Khurpi followed by raking in both ways. - If the condition of lawn is good only raking is
sufficient to loosen soils. - Then mow the grass thoroughly until the old
stumps/runners is well trimmed and expose to sun.
100Watering
- Lawn need regular water supply for its continuous
growth. - Watering must be thorough and as frequent
depending upon the weather conditions. - Frequent watering is beneficial rather than heavy
watering at long interval. - Heavy watering may encourage the deep rooting
weeds to come up
101Irrigation
- Sprinkler irrigation is the best method for
watering lawn for even distribution of water. - Pure water should be used as saline or brackish
water burns the grass specially during summer. - Winter dew is very beneficial for lawn.
102Weeding
- Weeds compete and make grass and less vigorous.
Hence, weeds should be controlled either by
manual weeding or by using chemicals. - Weeds should be removed at regular intervals as
and when seen. - More frequent weeding is required in rainy season
than in the winter months. - Weedicide 2,4-D is the most effective chemical
used for lawn weeding.
103Pests
- Termites Termites attack in summer months
- Termites attack stem roots.
- Management
- Heavy watering
- Application phorate/neem cake or pongamia cake
104Pests
- Whitefly
- Symptoms Green colour turn to pale dull to grey
- CM Spray systemic insecticides.
- Mealy bugs Mostly attacks Bermuda hybrid grass
in summer months.
105Pests
- Brown patches
- Management
- Drenching of systemic pesticides / phorate.
- Maintain high moisture levels in summer months.
106Brown patches
107Pests
- Root grubs It is minor lawn pest.
- CM Drenching of systemic pesticide.
- Slugs They are seen in water logged conditions
Can be controlled by liming, or keeping gunny
bags wetted with salt water
108Diseases
- Damping off It appears mainly due to water
stagnation and poor drainage of the lawn. - Fairy ring causal organisms Marasmius
ordeades, Psalliota compestris, Leipiota
morgani - Symptoms
- These fungi cause circular rings on the grass.
Rings may not be complete with an appearance and
are of horse shoe shape. Grass turns brown,
rings, widen in circles from few centi metres to
meters. - Control measures Drenching of soil with Bordeaux
mixture or spraying of copper fungicides like coc
_at_ 0.3, Blitox _at_ 5g/litre of water.
109Other problems
- Yellowing of lawn
- More prevalent in wet weather
- It is caused by water logging in heavy rainfall
areas and lack of water. - Deficiency of Nitrogen.
- Hardening of a soil, which creates oxygen
deficiency in roots. - Management
- loosening of soil with help of Khurpi or raking
reduces yellowing. - Controlled by drenching with COC or Dithane M-45_at_
3g/lit or Bavistin 1g/litre
110Other problems
- Frost Injury
- In cold region grass is injured due to frost
- In N India grass is injury is due to frost
- Management
- Spraying of water in the every evening and early
in the morning after the frost
111Other problems
- Thatching
- Formation of straw like layers of dead stems,
leaves and roots of grasses is called thatching - It can be controlled by manual removal
- Earthworms
- Affect lawn by depositing their extreta
- Cause a circular ring of thin coloued or dead
grass - Control- Bavistin drenching 1g/l or Dithane
M-45_at_3g/l, Neem or Pongamia cake _at_500g/sqm
applied before rainy season - Termites
- Controlled by application of Phorat/Thimet
112SPRINKLER IRRIGATION
113RAKER
114DISEASES
1 -FAIRY RING.
- This is caused by the soil borne fungi.
- The fungi produce a circular ring like
appearance on the leaves. - Rings may not be complete and give the appearance
like horse shoe. - This disease can be controlled by drenching the
soil with blitox_at_ 5 g/litre of water.
