HOW TO GROW OUTSIDE MUMS 


For your convenience we are offering a few suggestions on care and culture of Chrysanthemums growing 
outside in the garden. 
Follow These 10 Keys To Success 
1. SELECT A RICH, WELL DRAINED SOIL. Mums are 
quick growing plants that do best in a rich, well drained 
soil rich in available plant food. Be sure that water 
cannot stand on site selected. 
2. SUNNY LOCATION—NOT CROWDED. A sunny loca- 
tion not hemmed in by trees or tall shrubs is essential. 
Mums love lots of fresh air. 
3. SINGLE SHOOT PLANTS, PLANTED APRIL 20 TO 
JUNE 20. Select single shoot plants, either new potted 
ones or divide your old clumps. They are vastly superior 
in growth and bloom. Large potted plants will flower 
well planted outdoors most any time. 
4. SPACE 18 IN. TO 2 FT. APART. This is very impor- 
tant as it allows for proper growth and ample room to 
cultivate. 
5. WATER WELL—but not too much. As Chrysanthe- 
mums grow fast they must not be allowed to dry out. 
6. CULTIVATE WELL TILL AUGUST 20. After August 
20 the side shoots that make plants for next year begin 
to form. Cultivation after that date should be done very 
carefully. 
7. PINCH BACK. About August 15 when plants are grow- 
ing rapidly cut or pinch the tops back to knee height, 
about two feet. A well rounded branched plant will 
result. 
8. SUMMER FERTILIZATION. After pinching back, when 
the new branching starts, give each plant half a palmful 
of fertilizer, 0-10-10, 2-12-6 or with as little nitrogen 
as possible. 
9. PICK FLOWERS. Picking flowers is a good practice as 
it encourages new root growth. Cut off all flowers when 
blooming period is over. 
10. WINTER MULCH. If possible cover crowns with an 
inch or so of sand then mulch with excelsior or straw. 
WHAT SHALL I DO? 
PLANT LICE—APHIDS—Spray with nicotine spray. elim- 
inate ants nearby. 
LEAVES BURN AT BASE—Maybe too crowded, too wet a 
location, plants not transplanted and divided, plants hungry 
—fertilize well. 
TOO TALL—FALL OVER—Plants not cut back—soil too 
rich in nitrates—too much shade—older taller varieties— 
select newer, more dwarf varieties. 
DO NOT BLOOM—Too shady—too rich a soil-—not divided 
and reset. 
PLANT A ROW OF MUMS 
Hardy Chrysanthemums develop to their fullest extent 
when grown in rows like carrots or cabbage in your vegetable 
garden. Plant them 2 ft. apart in rows at least 3 ft. center 
to center.
