Chrysanthemum Pot Plant Culture 
Watering and Humidity 
After planting, water thoroughly to set the soil around the roots. Repeat this type of watering when 
the soil gets on the dry side. Organic matter in the soil will facilitate watering and will tend to avoid 
extreme fluctuations in moisture supply. Overwatering will rot the roots and cause a yellowing of the 
foliage. For best results grow all potted chrysanthemums under glass. Keep humidity in house by wet- 
ting down benches and walks with an occasional syringing over the plants. 
Fertilizing 
The foliage should retain a bright green luster throughout the life of the plant, and the lower leaves 
should never be allowed to lose their color and turn to a light green due to low fertility. A strong 
well grown pot plant is a well fed plant. Pot plants should be fed more often than those grown in a 
bench as constant leaching will lower the nutrient level in pots faster than under bench culture. Sev- 
eral light feedings should be made with a complete fertilizer such as Electra. This can safely be used 
at the rate of | teaspoonful per 6” pot. Liquid fertilizers are also very effective. It has been found 
that more frequent feedings of a weak nutrient solution is better than fewer heavy feedings. Last 
feeding should be made when the buds are forming. 
Diseases and Insects 
A regular spraying or tumigation with Parathion will control red spider, thrip, aphid and leaf tyer, 
the most troublesome insects affecting pot plants. If by chance plants are grown out of doors, weekly 
spraying with Parzate will prevent leaf spot. 
Shading and Disbudding 
Some procedure as for cut flower crop. Black cloth treatment should continue until the buds are taken. 
The last pinch is usually made at the same date short day treatment is started. However, if you are 
troubled with tall potted plants, delay the last pinch until 5 or even 10 days after starting the shading 
program. Disbud each shoot to one bud when buds are large enough to handle. 
Hardy Mum Pot Plants for Mother’s Day 
Garden or hardy 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 results 5 cuttings seedy be planted 
into a 6" pot or 2 cuttings into a 4’ pot. After these pot plants are through flowering they should be 
cut back within three 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 facilitate selection we 
are offering a 500 cutting collection suitable for this culture. This collection has the better varieties 
which have been tried and proven.
