NAPHTHALENE TREATMENT — Many growers 
use naphthalene flakes in control of Thrips in storage. After 
the bulbs are thoroughly cured and dry, mix with 1 pound 
of flakes for 2000 bulbs. Cover tightly with paper or 
canvas for at least two weeks, then shake out the flakes 
that remain and thoroughly air the bulbs. 
DIP — Dry rot can be largely controlled by dipping 
your bulbs just before planting. Use a solution of 1 oz. 
of corrosive sublimate to 7 gallons of water and let the 
bulbs soak for 12 hours until the solution has penetrated 
under the husks. Corrosive sublimate is very poisonous 
internally and great care should be exercised in handling 
it. It will also control Thrip and other insects. This 
solution can only be used in earthen ware or wooden 
containers as it reacts on metals. 
Basal rot and core rot are becoming more common. 
The Michigan State School has found a believed cure. 
After the corrosive sublimate treatment dip in a solution 
of 1 pound of Calogreen or fine ground calomel to 10 
gallons of water. This Calogreen or calomel does not dis¬ 
solve in water but remains in suspension and will form a 
protective covering over the bulb. Add 1 ounce of salt 
to 5 0 gallons of solution to hold the preparation in sus¬ 
pension. 
Well ventilated storage and the use of screen bottom 
trays will help prevent storage diseases. 
Hints on Greenhouse Forcing 
Every Greenhouse owner should grow Gladiolus to 
help supply the demand for cut flowers in the Spring. 
By varying the time of planting by two week intervals 
there will be a nice supply of gladiolus for March, April 
and May when they will prove profitable. 
A few suggestions: 
1. Plant for forcing during the period from January 
15 to March 30. No time is gained by planting earlier 
as the bulbs will require a longer period to bloom, and 
will be more apt to prove blind. 
2. Use only the soundest, first size, young bulbs. 
3. Plant in larger quantities varieties that have proven 
profitable ih the past and try a few of the newer recom¬ 
mended softs.

4. Keep heat at carnation house temperature. 
5. Water carefully and thoroughly and never allow 
the bench or bed to completely dry out. 
6. Use medium rich soil as rich soil tends to produce 
all foliage. Well-drained soil used for carnations is, rec¬ 
ommended.
