CUT FLOWER PRODUCTION
CUT FLOWER BED: Azumi XL is tolerant of stem rot (fusarium), but steam sterilization and crop rotation is recommended to prevent disease.
TRANSPLANTING: Transplant at 3 true leaves to ensure proper development and enough stem length. Select a rich soil full of organic matter where Asters were not previously grown the previous year. Optimum pH is 5.5 to 6.5.
OPTIMUM GROWING TEMPERATURE: 60-77°F / 16-25°C
FLOWERING TYPE: Spray: Spacing 5-6 x 5-6". Disbud: Spacing 4 x 4"
FLOWERING: Bud formation begins under long days (>16 hours) at a temperatures above 60°F/16°C with final development under short day conditions. In general, Aster AzumiXL flowers in 13-14 weeks (90- 100 days) after sowing.
DISBUDDING: To produce larger flowers disbud the stems as follows:
Step 1* 4-5 weeks before harvest - Remove upper side branches with buds
Step 2 2-3 weeks before harvest - Remove lower side branches with buds
Step 3 1 week before harvest - Remove remaining flower buds if needed
*Begin when the first top flower reaches 0.4-0.8 inches / 1-2 cm.
POST-HARVEST CARE: Cut stems when 2-3 flowers are 1/4 open. Strip off bottom leaves and place stems in tepid water in a cool area to allow for rehydration.
CULTURE WATCH POINTS:
• Night temperatures below 60°F /16°C promote vegetative growth and increase the risk of abnormal flower development; especially when using cyclical lighting.
• Short days following flower bud initiation, although not required, promote faster and more uniform flowering.
• Use steam sterilization and crop rotation to prevent stem rot (fusarium).
