IMPORTANCE. • Lawn isone 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 day’s hard work. • Ideal place for holding parties and different Social functions. 6
- 7. Characters' of lawngrasses 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. 7
- 8.
- 9. SITE SELECTION • Theselected 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
- 10. • More over, –Thedried 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 10
- 11. SOIL… • For establishmentof 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 11
- 12. • A slightlyacidic 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 12 SOIL…
- 13. Drainage… • 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 13
- 14. • Rough surfaceleveling 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 14 …Drainage..
- 15. • 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 15 …Drainage
- 16. Manuring and Grading •After digging is over, – Soil is manured and graded • If the soil is already fertile- Don’t 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 16

Land Preparation • Thegerminated 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. 73
- 74. PLANTING 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.. 74
- 75. [a] 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. 75
- 76. [b] DOOB ORBERMUDA 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. 76
- 77. Method of plantingGrasses 1. Seed sowing 2. Dibbling 3. Turfing 4. Bricking 5. Turf plastering 6. Planting on polythene sheet 77
- 78. 1. 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. 78
- 79. The seeds willgerminate 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 1. SEED SOWING.
- 80.
- 81. 2. DIBBLING. • Itis 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. 81
- 82. 3. TURFING • Itis 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. 82
- 83.
- 84.
- 85.
- 86. 4. BRICKING • Itis 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. 86
- 87. • Grass rootswith 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. 87 5. Turf Plastering method :
- 88. 6.PLANTING ON POLYTHENESHEET. • 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. 88
- 89. Maintenance 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. 89
- 90. • Lawn rolling •Mowing • Manuring • Scraping • Raking • Watering and • Weeding 90 Maintenance of lawn
- 91. • The purposeof 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. 91 Rolling
- 92. Mowing • Mowing isthe 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 92
- 93. Moving • Moving isimportant 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
- 94. • 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 94

Top dressing andmanuring • 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 @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 1:2:1 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. 99
- 100. Scraping 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. 100
- 101. Watering • Lawn needregular 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 101
- 102. • Sprinkler irrigationis 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. 102 Irrigation
- 103. Weeding • Weeds competeand 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. 103
- 104. Pests Termites : Termitesattack in summer months • Termites attack stem & roots. Management – Heavy watering – Application phorate/neem cake or pongamia cake 104
- 105. Whitefly : • Symptoms: Green colour turn to pale dull to grey • CM – Spray systemic insecticides. Mealy bugs : Mostly attacks Bermuda hybrid grass in summer months. 105 Pests
- 106. Brown patches • Management –Drenching of systemic pesticides / phorate. – Maintain high moisture levels in summer months. 106 Pests
- 107.
- 108. • 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 108 Pests
- 109. Diseases • 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 @ 0.3%, Blitox @ 5g/litre of water. 109
- 110. Other problems Yellowing oflawn – 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@ 3g/lit or Bavistin 1g/litre 110
- 111. Other 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 111
- 112. Other problems Thatching • Formationof 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@3g/l, Neem or Pongamia cake @500g/sqm applied before rainy season Termites: • Controlled by application of Phorat/Thimet 112
- 113.
- 114.
- 115. DISEASES • This iscaused 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@ 5 g/litre of water. 115 1 -FAIRY RING.
