Cultivation.
The gladiolus needs the same stirring of the soil that is given to other
crops. The reason why the soil must be stirred is a question upon which
there are various opinions. Some hold that it is to kill the weeds; some
to conserve moisture; others, to let the air to the roots; and, still
others, to render the plant food in the ground available. Probably all
are right, and the summing up seems to be, "to make the crop grow," so
the safe way is to stir often. This cannot be overdone. A crop may be
cultivated every day if desired, provided that good judgment is
exercised as to the condition of the soil. It should not be stirred when
too wet. The gladiolus has not a very long season for growth, and if
best results are to be obtained it must be kept growing continuously.
The next best thing to frequent stirring of the surface is a mulch to
keep it loose and moist, but this is not as good.
Support.
The critical period in the life of the gladiolus is the blooming season,
and some support at that time is almost indispensable. It grows so tall
and offers so much resistance to the wind that the stalk is liable to be
strained or broken, to the detriment of the bulb, and every effort
should be made to keep it upright and prevent its being injured, even a
little. When we consider that each leaf is connected with the bulb, and
is doing its part towards bringing it to maturity, we readily perceive
that whatever hurts the foliage also hurts the bulb, and realize the
importance of preventing, as far as possible, any weakening of the
connection between the two.
Deep planting is the first safeguard, and this is rendered still more
effectual by ridging up the rows. Cutting the spikes as soon as the
first flowers open is a great advantage, lessening the weight of the
tops and diminishing its resistance to the wind, besides relieving the
plant of the burden of nourishing the blooms. If the flowers are not
wanted, the spikes can be cut as soon as they are high enough to escape
the foliage, and this is still better. When the gladiolus is grown as a
field crop, there are so many tops together that they support each other
to some extent. When grown in small areas, it is a good plan to stretch
wires along the rows about a foot from the ground, and tie the stalks to
them. When the plants are scattered irregularly over the bed, they may
be supported by tying each one to a short, inconspicuous stake sharpened
and driven into the ground so that the top is fifteen to eighteen inches
high. The same stakes may be used year after year, and it improves the
appearance of the bed to have them painted green.
