Mums grow best in full sunshine. They produce colorful blooms when days get shorter and nights get longer. The life cycle of the plant depends on the amount of daylight. This is why experts advise against placing mums near nightlights or streetlights. The light may interfere with their normal growth cycle. The plants may develop buds too soon. 菊花在日照充足时长势最好。当白昼变短黑夜变长时，它们就会开出缤纷的花朵。菊花的生长周期取决于日照时间。所以专家建议不要将菊花放置在夜灯或路灯附近。灯光会影响菊花的正常生长周期，导致花蕾过早开放。 In climates where temperatures fall below freezing, plant mums at least six weeks before the first frost is expected. 在零度以下的气候条件下，应在霜降前6周种植菊花。
