Established Lawns Are Given: Increase or decrease the frequency of mowing according to the rate of growth, which varies from season to season, and may be influenced by bad weather, feeding, irrigation, the varieties of grass being grown and the general health of the turf itself.
Different types of lawn require a different frequency of mowing. Fine established lawns are given, for example, should be mown every two to three days,
average established lawns are given at least every seven days and preferably at intervals of three to five days and, for other sod established lawns are given, mow at least once a week.

In really hot weather raise the cutting height an extra half inch. Give the last mowing of the season so that the grass goes into winter two to three inches long. kept lawns of creeping bent may be cut to a height of from one inch to less than half an inch.
Southern kept lawns of subtropical grasses are generally mowed to a height of one inch. Temporary winter kept lawns of ryegrass are cut at one and a quarter inches.
Mowing machines should be used when the grass is dry, scythes and sickles when it is slightly moist. For the kinds of mowers see Chapter 16.
Hand mowers cut with a revolving reel of several curved knives that scissor against a stationery horizontal bed knife. They come with from four to nine knives. For ordinary kept lawns, five are best; for creeping bent kept lawns, seven. Hand mowers may be had with rubber-tired or plain metal wheels. Those with ball bearings run best.
On The Other Hand See Lawns May:Before beginning a creeping bent lawn consider these facts. It is more costly in labor than making other type lawns may from seed. If you have to buy the stolons (possi¬bly you can obtain them from an estab¬lished lawn without cost) they are more expensive than seed. lawns may of creeping bent require a tremendous amount of up¬keep—frequent mowing, watering, fertiliz¬ing, top-dressing, etc. They are really for specialists.
But even in well-cared-for lawns may, weeds appear. The worst, crab grass, is dealt with in Chapter 13. Some weeds clearly indicate the adverse condition that triggers their development. Eliminating them depends upon correcting the basic fault. Sheep sorrel, a sure indicator of too-acid soil, is eliminated by liming sufficiently. Clover flourishes in neutral or alkaline soil. Do not lime if it is abundant, and you want to discourage it. Chickweed, mouse-eared chickweed, speedwell, self-heal, ground ivy, sedge and lawn pennywort invade lawns may where the soil is too moist and the grass weak.
