That strong, healthy, one-year-old plants are in every way to be
preferred to two or three year old ones has been demonstrated by many
carefully conducted experiments, and is now universally recognized by
intelligent and observant asparagus growers. The most noteworthy and
accurate experiments
in this line were made by the famous French
asparagus specialist M. Godefroy-Leboeuf, who planted twelve stools of
one, two, and three years old respectively in the same soil under the
same conditions and at the same time. Calling those plantings Nos. 1, 2,
and 3, the following are the results obtained:
First Year.--No. 1.--All the stools came up before May 4th, and
were well grown.
No. 2.--Ten stools showed above ground before May 4th, one on the
10th, and one appeared to be dead. The asparagus heads were very
fine--finer, indeed, than those of No. 1.
No. 3.--Eight stools showed above ground before May 4th, one on the
12th, and three gave no signs of life. The heads were very fine at
first, but they became bent toward the end of the year (September
15th), and were much weaker than those of No. 2.

Second Year.--No. 1.--Well-grown, regular, and strong heads,
which measured on September 15th one inch in circumference.
No. 2.--Well-grown but irregular heads, somewhat weaker than those
of No. 1.
No. 3.--Only pretty well-grown heads, very irregular, some of the
stools having as many as eight or ten, but all very weak. One stool
died after growing two heads.
* * * * *
Third Year.--No. 1.--Magnificent growths, the heads measuring on
April 10th from two inches to three and one-quarter inches in
circumference.
No. 2.--Growth passable only, but very irregular. Some of the
stools were very small. The finest of them produced heads which
from April 8th to 10th only measured two and one-half inches in
circumference.
No. 3.--Growth very poor and very irregular. Some of the stools
continued to produce small heads not much thicker than a quill pen,
the largest being from one and one-half inch to two inches in
circumference.
* * * * *
Fourth Year.--No. 1.--Growth very remarkable. The heads began to
show on April 3d, 4th, 5th, 7th, and 10th. Some were from three and
one-quarter inches to four inches in circumference, and measured
four and three-quarter inches. Fifty of the heads formed a bundle
which weighed seven pounds.
No. 2.--Growth passable, but later than No. 1. The heads made their
first appearance on April 6th, 10th, and 11th. Many of them were
very small; fifty of them barely made half a bundle, and only
weighed three and three-quarter pounds.
No. 3.--Growth but poor, and somewhat late. The heads made their
appearance on April 4th, 6th, 9th, and 11th; one did not show till
the 22d. Fifty heads barely formed half a bundle and only weighed
two and one-half pounds.
To sum up, it is clear that the plants of a year old in their
fourth season--that is to say, after having been planted out for
three years--gave a bundle weighing seven pounds, while those of
two years old only gave three and three-quarter pounds, and those
of three years old only two and one-half pounds; in other words,
taking round numbers, the plantation made with the one-year-old
plants produced double the crop of the two-year-old plants and
treble that of the three-year-old plants. The reader may easily
draw his conclusions from the preceding facts.
Equally important is a careful selection of the individual plants to be
set out. A crown with four or five strong, well-developed buds is far
better than one with a dozen or more of weak and sickly ones, as the
latter will always produce thin and poor spears of poor quality. It is
therefore highly to be recommended to select only plants with not over
six buds and discard all others. The roots should be strong and of
uniform thickness, succulent and not too fibrous. Dry or withered roots
have to be cut off, and plants with many bruised or otherwise damaged
roots should be rejected entirely. The best roots are the cheapest.
