Cool night temperatures promote early flowering of garden mums while very warm night temperatures can delay flowering. Expect garden mums grown in a covered greenhouse to flower two weeks later than those grown outdoors for fall sales. Fast Crop for Fall Plant July 16 to 30 and space on 12-inch centers. Do not pinch and don't worry about crown buds. Water and feed immediately and regularly to push this crop.
Cultivars flower up to a week later than natural season, allowing a longer period of sales.
Because they are naturally later, their buds are seldom harmed by early frost. More than twice as many plants can be grown in the same area since the fast crop will make smaller finished plants, 10-14 inches in diameter. Plant one rooted cutting per 6.5 inch pot and space plants on 12-inch centers. B-Nine is not needed. A clean production area is important to disease and insect prevention and prevention saves money.
