How many years does it take for an osmanthus seedling to bloom? A 10-year-old osmanthus tree grows tall but does not bloom

1. How many years does it take to bloom?

There are many ways to propagate it, and the growth will be different depending on the method, so how long it takes to bloom is not fixed. Ordinary osmanthus seedlings propagated by seeds need to be cared for for a long time before they can bloom. They will not bloom before the age limit, which usually takes about 10 years. Grafted seedlings bloom relatively early, and some can bloom in the same year, but the number of flowers is small. It usually takes four years for seedlings grown from cuttings to bloom.

2. Reasons for growing taller but not blooming

1. Insufficient light: It prefers light and is a long-day plant. During the growth period, it must be exposed to more sunlight. Only with sufficient light can it accumulate more nutrients and promote flowering. If there is a lack of light, the plant will easily grow too tall and only grow without blooming.

2. Improper fertilization: It consumes a lot of nutrients during the growing season and needs additional fertilizer. However, if too much nitrogen fertilizer is applied, especially before flowering. Then it will just grow, the flower buds will not differentiate, and thus it will not bloom. It is necessary to increase the application of phosphorus and potassium fertilizers to promote flowering.

3. Excessive watering: If the plant is in dormancy or is overwatered during the peak growing season, it will have sufficient water and will grow vigorously, but it will not bloom and will only grow leaves and height. You need to adjust the watering method and control water in time to allow it to accumulate nutrients and promote flowering.
