When does the zinnia usually bloom?
When the zinnia blooms, its layer upon layer of petals is extremely beautiful. Many people who grow zinnias think day and night about them blooming, so when is the zinnia's flowering period?
1. Zinnia flowering period
Zinnias generally begin blooming in June and keep blooming until October; the blooming time is usually 60 to 70 days, and the flowering period is four months. Moreover, under different growing conditions, the length of blooming varies; some will bloom for 50 days, and with good care they will bloom for 120 days.
2. How do you extend the flowering period?
1. Pinching: When the zinnia seedlings are 10 cm tall, they need to be pinched. This can control the plant height and reduce nutrient consumption, and it greatly helps extend the zinnia's flowering period. In addition, leave two pairs of leaves at the base, and promptly remove spent flowers after blooming.
2. Watering: Zinnias bloom in summer, when the soil moisture is very important for flowering. We should water frequently to maintain soil moisture. An appropriate amount of watering helps extend the zinnia's flowering period. Be careful not to water too much normally, unless there is continuous drought.
3. Fertilizing: When zinnias bloom, they consume a large amount of nutrients, so proper fertilization will affect the flowering period. During the growing period, apply diluted liquid fertilizer 3 times. At the seedling stage, mainly use nitrogen and potassium fertilizer; at the bud stage, mainly use phosphorus fertilizer; in early September, apply a compound fertilizer of nitrogen, phosphorus, and potassium.
4. Sunlight: When zinnias bloom, pay attention to the duration of sunlight: if sunlight is longer than 14 hours, flowering is delayed, it takes 70 days from sowing to flowering, and there are many ligulate flowers; if sunlight is shorter than 12 hours, flowering is earlier, taking only 60 days from sowing to flowering, but there are more tubular flowers.
Although zinnia blooms are beautiful, you need to pay attention to careful care so that the flowering period can be longer and the flowers can be more vivid.
