Vegetable Growing in Colorado.

are often troublesome about the lamps in the evening on account 
of their habit of flying to the light in the night time. The moths 
are more or less common through the summer, hut are usually most 
abundant in Colorado during the latter part of May and June. 
When the worms become fully grown, they burrow into the earth, 
change to the pupal or resting stage, and later emerge in the moth 
stage mentioned above. 
Remedies .—In large fields, the method of control is to plow 
the ground during the summer and keep it cultivated and free from 
all vegetable growth until winter. This will prevent the moths lay¬ 
ing eggs and will nearly always result in freedom from cutworm 
injuries the following spring. 
If it is impossible to keep the garden tract free from vegeta¬ 
tion late in the season, it is necessary to depend upon other means 
of control. One of the best of these remedies is to watch for the 
appearance of the plants that have been cut off during the night, 
and dig out and destroy the worms that are doing this work. Indi¬ 
vidual plants, or hills, of any plants in the garden that are liable to 
be attacked by the worms, may be protected by surrounding each 
plant or hill by a collar made of stiff paper, or tin. Tin cans may 
be cut in suitable sizes by means of tin shears and be used from 
year to year. A good size for the protection of a single plant is a 
strip of tin or paper three inches wide by five inches m length. The 
strip is curled in the form of a cylinder and placed about the plant 
and then pressed into the ground so that the top of the cylinder will 
project one and a half or two inches upon the surface of the ground. 
The worms will almost never climb over one of these cylinders to 
attack the plants. Care should be taken not to enclose the worms 
within the cylinder when it is placed about the plant. 
Small weeds between the rows of plants in the garden are also 
a great protection from cut-worm injuries. When the cultivated 
plants are small, the worms feed as freely upon most of the garden 
weeds as upon the cultivated plants. If the weeds are all hoed out, 
the worms are compelled to feed upon the few cultivated plants that 
remain. It is bad advice, without doubt, to recommend allowing 
weeds to grow in the garden, but this can often be done judiciously 
for a week or two early in the season when the plants are tender 
and easily destroyed by the worms. As soon as the plants become 
woody and resistant to the worms the garden, of course, should be 
freed from all weeds and kept in as good condition as possible for 
the growth of the cultivated crops. .
