Asparagus is a very hardy plant, and will bear almost any amount of frost when established; nevertheless, it is well to cut off the withered tops in the fall, and cover over a mulching of some 'suitable material, to keep up the fertility, for which purpose there is nothing better than a sprinkling of guano, and a thick layer of sea-weed; but when this cannot be got, the next best substitute is a dressing of salt and barnyard manure or rotted leaves. The young shoots ought not to be cut until the third year after planting, unless there hae been an extraordinary luxuriance; but after this, the beds will continue to yield in abundance for twelve or fifteen years. Mueh, however, depends upon a good beginning, and the after yearly dressings, besides which, when it is seen that the continually rising sprouts are becoming weak from prolonged gathering, it ought to be discontinued. No exact rule can be laid down as a guide, in this respect, but gene* rally, it may be extended to a period of two months; and remember, further, that unless all the sprouts are kept cut during this time, the roots will almost discontinue to produce more; consequently, the crop will be much reduced.
