After the most careful preparation of the land, annual weeds are certain to appear, and every weed, if left alone, will choke a number of the surrounding grasses. Frequent mowing checks these weeds, but plantains, thistles, and dandelions must be taken up, each one singly, about an inch below the surface. A pinch of salt dropped upon the cut root will effectually prevent new growth. The lad who does this work should understand what he is about, for a plantain merely cut off below the collar will send out half-a-dozen shoots, in the same manner as sea kale, and prove a greater nuisance than the original crown; and the careless use of salt will kill a lot of grass plants. Daisies should be lifted separately, each plant with its root entire, and although new growth will here and there appear for a second or even a third time, the daisies will be weaker, and a little perseverance will speedily rid a large grass plot of every one of them. Another efficient mode of eradicating weeds is to dip a wood skewer into sulphuric acid, strong carbolic acid, or one of the liquid weed destroyers, and then plunge the skewer perpendicularly into the heart of the plant. The result is deadly and instantaneous; but the use of these destructive fluids needs great care to avoid personal injury or the burning of holes in clothing. The bottle containing the liquid must be kept in a place of security. In extirpating weeds there is nothing like system. Instead of aimlessly wandering hither and thither, it is more economical in time and labour to mark off with a garden line a strip six feet wide, and clear the weeds from the enclosure. Follow with successive strips until the whole surface has been dealt with, and it is surprising how quickly a large area may be divested of weeds. After sowing grass seeds, how soon will the ground be fit for use? is a question frequently asked. No definite answer can be given. The time depends on the period of the year, the weather which follows the sowing, and the attention bestowed on the rising plant. To these influences must be added the nature of the soil, aspect, and district. In August or early September, sowing should produce, under favourable circumstances, and with generous treatment, a good turf during the following summer. Spring sowings are specially subject to the vicissitudes of the season. When the atmosphere is genial and the plot receives due attention, the plant rapidly fills the soil, and a thick sward results towards the end of July or the beginning of August. But it is desirable not to subject it to hard use until the following year.
