Sweet-scented osmanthus likes light and is suitable for growing in acidic soil, but according to this reader, the growing environment of sweet-scented osmanthus can be said to be quite bad. Potted sweet-scented osmanthus is mostly cuttings, grafted seedlings, short flowering time. Cutting sweet-scented osmanthus blossoms in the fourth year, grafted osmanthus, silver osmanthus and Dan can blossom in the second year, while four seasons osmanthus blossoms in the same year, but in cultivation, potted sweet-scented osmanthus still does not bloom at flowering time.

Analysis on the reasons for the non-flowering of Osmanthus fragrans

1. If the temperature of entering the room too early is above 10 degrees Celsius, the sweet-scented osmanthus can not get enough dormancy. Make sweet-scented osmanthus sprout and spread leaves early, consume a lot of nutrients, coupled with lack of light, plant weakness, affect flowering. Countermeasure: ensure low temperature hibernation. Potted sweet-scented osmanthus overwintering temperature 3-5 degrees Celsius, above 3 degrees Celsius do not need to enter the room, maintain the natural temperature; below 3 degrees Celsius, enter the room. After entering the house, it will be dormant at a low temperature so that it can thrive and flourish in the following year.

2. Leave the room prematurely. After coming out of the room in spring, the wind blows in the sun, the leaf tips are dry, and it is not easy to blossom even if the new buds come out again. Countermeasures: when you leave the room in spring, you should move out of the room on cloudy or rainy days, avoid sudden exposure to the scorching sun, and make it gradually adapt to the outdoor environment.

3. Lack of nutrients. Sweet-scented osmanthus like fertilizer, some potted sweet-scented osmanthus, several years did not change the pot to change the soil, resulting in insufficient nutrition, root knots can not be extended, affecting flowering. Countermeasure: if the basin soil is too long, the basin soil should be changed. The soil of the basin is changed every 1-2 years, and a small amount of hoof can be used as base fertilizer at the bottom of the basin.

4. The sweet-scented osmanthus needs more than 10 hours of light, otherwise the leaves will not flourish and the flower bud will not blossom. Countermeasures: to ensure long sunshine, there should be more than 10 hours of sunshine every day to meet the needs of sunshine.

5. Excessive watering causes rotten roots and fallen leaves, which affects flowering. Countermeasure: reasonable watering. Should maintain 30% water content, hot summer, 60% water content is appropriate, not too dry and too wet.

6. Excessive nitrogen fertilizer causes branches and leaves to grow and affect flowering. Countermeasures: nitrogen fertilizer should not be too much, it should be applied with phosphorus and potassium fertilizer. Sweet-scented osmanthus needs a lot of phosphorus and potassium fertilizer, which can be topdressing outside the root, and 0.1% Mel 0.2% potassium dihydrogen phosphate is sprayed on the leaves.

7. Soot and oil dirt pollution sweet-scented osmanthus is not resistant to soot and oil fouling, and its leaves have been polluted by soot and oil fouling for a long time, resulting in poor growth and even leaf shedding, affecting flowering. Countermeasure: prevent pollution. Fine gauze can be used to gently test the leaves to keep the leaves clean and rub them once on the 15th day to facilitate photosynthesis and make the plant grow healthily.

8. Lack of pruning, sweet-scented osmanthus has developed root system and strong sprouting ability. If it is not pruned properly, the branches and leaves will be too dense, which will affect flowering. Countermeasure: trim properly. Cut off the diseased, weak and overdense branches before leaving the room, and cut them properly according to the plant shape, so as to ventilate and penetrate the light and promote its flowering.
