CHRYSANTHEMUM MANUAL 
Chrysanthemum Pot Plant Culture 
Plant the rooted cutting directly in the pot. Do not 
plant cuttings too deep as in hot weather this will cause 
Rhizoctonia to develop in the stem. It has been found 
that the best way to plant the cuttings is around the 
pot and not the common four with one in the center. 
No-Pinch Method. Plant 7 to 9 cuttings in a 6-inch 
pot and give short-day treatment the same day. It is 
a very rapid way to grow potted plants the year- 
around. The blooms will be very large and the stems 
will be much stronger than oles growing pinched 
plants. 
Single-Pinch Method. The most common method of 
growing potted plants today. It is much faster and 
produces a very uniform plant with strong stems not 
too tall. Plant 5 or 6 cuttings in a 6-inch pot. Pinch 
the plants 5 days after planting and give short-day 
treatment the day you pinch. 
We suggest that those plants that are planted be- 
tween September 15 and January | be given 12 days 
of additional light before they are pinched. The re- 
quirements for additional light can be found on page 
|. For those plants planted from January | to May | 
we suggest that 5 days of additional light be given. 
The rest of the year the length of day is long enough 
to produce long day effects. Like all rules there are 
exceptions and for these exceptions study the year- 
around pot plant schedule. 
Two-Pinch Method. Probably the most common sev- 
eral years ago, but still very good results can be ob- 
tained from this method. Plant 3 or 4 cuttings in a 
6-inch pot. Pinch the plants the first time 14 days after 
planting and wait 21 days and pinch the second time. 
Long-day treatment should be maintained either nat- 
urally or through the use of additional light during this 
period. Short-day treatment should start at the time 
of the second pinch. 
Modified Two-Pinch Method. We recommend this 
cultural method for those varieties that normally grow 
too tall, such as Queen's Lace, Indianapolis varieties, 
Copperhead, etc. Grow the plants similar to the 
"Single-Pinch Method" and start the short-day treat- 
ment. After the plant has been given the short-day 
treatment — 21 or 28 days depending on the time of 
year, pinch the second time. This second pinching will 
not delay the flowering very much more than one week

but will keep the plant much shorter than if not given 
this second pinch. 
If plants flower too tall, you had better delay your 
last pinch by 10 to 14 days. In some localities pot 
plants will grow taller than in others. Sometimes too 
much shade on the glass will cause the plants to 
stretch. Yet there are many varieties that grow too 
tall when given the short-day treatment the day of the 
last pinch. If this is true, start short-day treatment 
and give the final pinch 10 to 14 days after short-day 
treatment was started. Royal Bronze, Indianapolis 
varieties, Queen's Lace, Yellow Lace and Little Amer- 
ica are often grown too tall, so delay pinching. 
Garden mum plants in full bloom make ideal potted 
plants for Mother's Day. This should be a valuable 
addition to the list of spring pot plants. For best re- 
sults, 5 cuttings should be planted in a 6-inch pot or 
2 cuttings in a 4-inch pot. After these pot plants are 
through flowering, they should be cut back to within 
3 inches of the soil level and planted into the garden. 
These same plants will bloom again in the fall. There 
is a long list of varieties to choose from, and to facili- 
tate selection, we are offering a 500 cutting collection 
suitable for this culture. This collection contains the 
better varieties which have been tried and proven.
