GENERAL CARE OF LAWNS
The lawn should never be rolled when it is wet and sodden, as this causes a hard crust to form on the surface, impedes drainage, and prevents air from getting to the roots of the grass.
Rolling should be done on a fine day when the weather is not too dry, or frosty. It is only intended to spread or “tiller” the grass, and keep the surface even, not to level the lawn.
It is advisable to rollperiodically in the winter, as well as in summer, altering the direction of the rolls from time to time.
Never let the grass on a lawn grow longer than 2 in., otherwise it will immediately start to deteriorate and take a long time to get back into condition.
Mow your lawn occasionally during the winter months, but choose a fine day for doing so, for grass still grows during the cold months, and, unless it is cut now and again, becomes ragged and untidy.
A lawn should be cut twice a week at least in the growing season. Before mowing the lawn sweep the grass clear of worm casts. These tend to injure the machine.
If grass is left to grow the whole winter it may have to be scythed. Do this as early in the morning as possible while it is full of moisture and the stems are stiff. Limp grass makes the work of scything harder.
Keep the mowing machine in tip-top condition, and see that it is brushed clean, and oiled, before it is put away.
Early morning mowing should be preceded by rolling, as the grass is not so likely to cling to the rollers, and make the machine run rather heavily.
The best time to water the lawn is early in the evening, when the great heat of the day is passed. If water is given in the day time the hot sun and air dry the moisture up so quickly that the grass gets very little benefit from it. The best method is to use a garden hose fitted with a fine rose, and to hold it so that it throws the water up into the air, and moistens the ground gradually, or to use a fine-spray sprinkler put on for an hour or so. To pour water direct on to the lawn and saturate it in places is a mistake.
It is a wise rule not to water an established lawn unless absolutely necessary. If watering is commenced it will have to be continued at least once a week during the dry spell. In place of this, run the mowing machine over the lawn frequently, and leave the grass lying where it falls, so that it may form a protection to the lawn. There are two or three exceptions to the rule of not watering a lawn. In the case of a young lawn not fully grown, the grass seed requires water every day, morning and evening, until it has become firmly established.
The same applies to a lawn newly turfed. Unless this is kept watered until the surface is set, and the grass well rooted, it will dry out, and wear patchy. The third exception is the games lawn, where hard use makes daily watering a necessity.
