The subject of asparagus was brought up for discussion before the Concord (Mass.) Farmer's Club, and Capt. Moore said:
One hundred and fifty years ago some book-maker asserted that asparagus grew naturally on the coast of Spain, in places where the high tides flowed; and inferred from this fact that salt was a specific fertilizer for this plant. From that time to the present the horticultural book makers have copied and handed down this theory. It has even been recommended to Apply as much as a bushel of salt to each square rod, to serve as a fertilizer to the asparagus, and at the same time kill the weeds. But some of the weeds will bear this amount of salt as well as the asparagus. A few years ago it occurred to him that the asparagus plants could appropriate but a very small part of this salt; as an experiment put out a bed of a quarter of an acre, without using any salt, and from this bed, treated like the others with the exception of the salt, he has cut his best asparagus, beating even Cono-ver's. Birds have dropped seeds from his bedsi n the thin soil of the pine woods back of his house, and the plants grow there six feet high, without manure or cultivation. He supposed, by-and-by, some new bookmaker might discover these plants, and from them deduce the theory that asparagus grows naturally in the sand of pine barrens.
A bunch of " Conover's Colossal Asparagus" (eighteen stems weighing twenty-six ounces) was sent to the Massachusetts Horticultural Exhibition. Capt. Moore, the same day showed twelve stems of his Concord variety that weighed twenty-four ounces. He knows of no reliable variety that can be perpetuated by seed. He prefers a rather dry, sandy soil for this crop. It can be manured at any time. If done in June most likely there will bo a heavy crop of weeds, at a time when it will not be convenient or easy to kill them. Would set the plants eight inches deep, for the greater safety of cultivating with the horse, without injury to the crown of the plant. If set shallow it may be cut earlier, but there is no profit in this, as the early cut has to compete in market with that from the South, aud the late (say after the 25th of May) always brings the best price, and the earliest cut is often injured by frosts. If we cut early must stop early, so as not to injure the bed. Best to renew bed when fifteen years old, as on young beds the stems are larger and of better shape.
Would change the kind of manure frequently.
Mr. L. had a young bed, a part of which was manured with nitrate of soda only, and that part looks as well as that on which barn manure was used.
Much of the asparagus raised about here the past year was crooked, and Mr. Moore thought it was owing to the prevalence of cold winds.
Mr. F. thinks the occasional crookedness of the shoots is caused by the drying effects of the wind, as the bend is always to the wind. In his experience sandy soil does better than heavy. Has a general impression that salt is beneficial. He used fifteen bushels to the acre.
