FOR BEST RESULTS SPRAY YOUR DAHLIAS 
PESTS 
SUCKING INSECTS 
THRIP, LEAFHOPPER, TARNISH BEETLE 
(Very severe through midwestern and south- 
ern states from July until October. Blast young 
buds and prevent bloom.) 
RED SPIDER 
(Only under hot, dry conditions in most sec- 
tions of the country.) 
GRASSHOPPER 
(Midwest, west and southern states.) 
JAPANESE BEETLE 
(Eastern states.) 
EUROPEAN CORN BORER 
(Eastern states.) 
SPOTTED CUCUMBER AND 
BLACK BEETLE 
(Prevalent in mid-summer.) 
STEMBORERS 
(Midwest, east and western states.) 
MILDEW 
(Prevalent in gardens having poor circulation 
also in cloth houses.) Foliage of varieties such 
as Edith Willkie, Jane Cowl, etc., is very 
suseptible to mildew. 
CONTROL 
Wash plants with garden hose in _eve- 
ning to dislodge the insects. Spray with “Hitox” 
which contains rotenone and pyrethrum. For 
leafhopper, rotenone dust may be used, follow 
directions on can. Begin spraying when plants 
are one foot high, spray at least once a week 
until October. 
Spray with pyrethrum, soap and water, 
Red Arrow or Hitox. Spray plants frequently 
with cold water using a garden hose. 
Poison bran; (brown sugar, paris green 
and bran mash). Cloth or screen wall around 
garden about 7 feet high. 
Any pyrethrum and rotenone spray, fairly 
heavy concentration. 
A bulletin, “Protection of Dahlias from 
Corn Borers,” is issued on request by: U. S 
Dept. of Agriculture, Bureau of Entomology 
and Plant Quarantine, Washington, D. C. 
Brush insects from bloom into a shallow 
pan of kerosene. 
Presence of Borers is usually revealed by 
the wilting of the lateral or branch of the 
plant. Cut off the wilted branch and slit the 
stem. Should the plant be too large use a 
strong concentration of pyrethrum and inject 
with an eye dropper. Stalk should be drained 
at bottom to prevent rot. Sometimes during 
heavy rains in July and August the plant will 
wilt from too much water in the stem. This 
is easily drained out by piercing the stalk 
with a knife at the base of the plant. 
Spray with Bordeaux mixture, following 
directions given on package. Dust with fine 
sulphur. 
HOW TO HANDLE ROOTED CUTTINGS 
ROOTED CUTTINGS must be potted immediately in 3 inch or 4 inch pots. Use a light mixture 
of soil consisting of 1 part garden soil, 1 part leaf mold or decayed peat and % part fine 
coal ashes or sand. Use no fertilizer. About half the cutting should be below the surface 
of the soil after potting. 
Dahlia cuttings cannot be successfully grown indoors. If a cold frame or greenhouse is 
not available, a makeshift cold frame can be constructed with a few panes of glass and a 
wooden box. . 
After potting, bury pots to % of their depth in ordinary soil in a cold frame. Coarse ashes 
underneath the pot may be necessary for drainage. Do not subject to excessive draft or 
heat until after ten days. Cold frames must be ventilated during heat of the day to prevent 
burning of plants. 
When plants have doubled their size they may be subjected to more severe conditions for 
hardening off, and in about two weeks may be set out where they are to grow. They should 
be not too tall for best results. Water thoroughly. 
Rooted cuttings sold at % of plant price. They are shipped from April till June.
