FOUR WAYS TO BUY 
POTASH-FED DAHLIAS 
GREEN PLANTS 
Green plants are sprouts or cuttings taken from 
clumps grown in especially built greenhouses; rooted in 
sand benches in propagating houses; potted and grown 
under greenhouse conditions until well established and 
then moved outside to cold frames for proper hardening 
off. When they reach you they are ready for planting. 
Their care after you receive them is fully described 
in our Cultural Instructions. 
Green plants will produce flowers equal to roots or 
pot roots when well grown for exhibition, but will not 
produce as large clumps for the following season. When 
properly grown from healthy stock, however, many 
varieties will produce nice clumps. 
Dahliadel green plants are always properly grown, 
and, in our specially designed shipping box have been 
successfully sent all over the United States. 
It is difficult to ship plants or rooted cuttings into 
the Deep South during a hot spell late in the season, 
so order early. State inspection slows up delivery on 
the West Coast but with proper timing, deliveries are 
not too bad. 
ROOTED CUTTINGS 
Rooted cuttings are sprouts or cuttings grown ex- 
actly as described under green plants (see above) up 
to the point where a good root system has developed. 
Rooted cuttings are wrapped singly or two together in 
live sphagnum moss on a special machine built for this 
work. In shipment the roots are fed moisture in live 
sphagnum. The leaves are in a ventilated air space. This 
insures the best and safest transportation. Rooted Dahlia 
cuttings are 1/3 less in price than plants. However, we 
do not recommend them unless you have had experience 
and are equipped to handle dahlia cuttings. 
Further directions on handling rooted cuttings will be 
found in our Cultural Instructions. 
ROOTS 
Dahlia roots are divisions of field-grown clumps of 
dahlias. Each root must contain at least one “eye” 
from which the plant grows. Sturdy plants and fine 
exhibition flowers grow from roots, and strong clumps 
harvested for the following season. As the planted root 
acts as a food storehouse for the growing plant, the 
growth of the plant is thus stabilized under adverse 
growing conditions. 
POT ROOTS 
Pot roots, as shown above in relative size to the 
average root, should not be judged adversely because 
of their size. Many experienced growers prefer pot 
roots. Pot roots are small clumps produced by plants 
grown mostly in 3-inch pots in the open during the 
late summer, and transferred in the Fall to greenhouses 
where they are grown under controlled conditions, and 
allowed to ripen naturally by the end of December. 
Pot roots will produce bushes and flowers equal to 
roots and in many varieties even better clumps on dig- 
ging. Our customers have written us as to their fine be- 
havior and we find them very satisfactory in every way. 
DAHLIA SEED 
Sow in flats or frames in early spring in light soil, 
cover the seed not more than one-fourth inch about the 
same as you would tomato seed, or better still cover 
seed with vermiculite. When first pair of true leaves 
are well developed transplant into small pots or flats 
and grow in cool temperature until they can be planted 
in the garden. Should they get too large, pinch back 
and shift to larger pots. 
Dahlia seedlings never come true to their parentage, 
but do usually show some similar characteristics in form, 
color or bush growth. You cannot grow seedlings of a 
named variety and produce the same variety.
