Greetings to Glad Fans, everywhere! 1948 was a perfect growing season with us in 
central Iowa, with plenty of rain and fine growing weather. A large increase of stock 
and fine quality of bulbs leads us to offer some surplus stock for sale. We have been 
growing Glads and exhibiting at the shows for the past twelve years, and growing seed- 
lings since 1985. We now have a few Seedlings of Merit and hope within another year to 
offer one or two new ones to the general public. 
The present list of varieties have all proved winners at the shows; they are all de- 
pendable growers and propagators as demonstrated by the fact I am able to offer surplus 
bulbs for sale.

Directions for Beginners 
Like most plants the Gladiolus is plagued by certain diseases and insect pests. 
Among diseases, those that affect the bulbs are most troublesome. Soaking the bulbs 
just before planting in one of the standard disinfectants is always recommended. Per- 
sonally, we prefer to use Semesan since tin cans may be used for containers. Somewhat 
cheaper is Bichloride of Mercury, a deadly poison if taken internally by man. When used 
as a dip for Glads one must use glass or wooden containers to prevent chemical action. 
Use Bichloride of Mercury, 1 oz. in 7 gallons of water; soak the bulbs in this for 10-12 
hours just before planting. This will eliminate most diseases of the bulb as well as the 
insect known as Thrips. The Gladiolus Thrips is a tiny black insect no wider than a 
pencil mark and may be distinguished by the cream colored pale mark across middle of 
the dark colored adult. This Thrips passes the winter chiefly on Gladiolus bulbs in stor- 
age. After digging bulbs cut off the tops close to the bulb; keep the bulbs spread thinly 
for drying. Place bulbs in old shoe boxes or open paper bags, but leave exposed to open 
air until well dried. During November or December fumigate with Napthalene flakes, 
using four tablespoonfuls to each 100 large bulbs; after three weeks remove the surplus 
Napthalene. If you wait until spring to fumigate some damage may occur to the bulbs 
from Thrips as well as Napthalene. Store the bulbs in the coolest part of your basement; 
35° to 40° F. is ideal.
