Why don't potted sweet-scented osmanthus bloom?

The reason why sweet-scented osmanthus does not blossom is due to lack of light. Sweet-scented osmanthus likes light. When the vegetative growth period is less than 30 ℃, its growth and development decline, vegetative growth becomes worse, and the number of flowering decreases. When the light is seriously insufficient, due to the weakening of photosynthesis and less nutrient accumulation, it can not blossom, so it is necessary to give sufficient light to sweet-scented osmanthus. ‍

Lack of fat. The growth and flowering of sweet-scented osmanthus need to consume a lot of nutrients. The barren or insufficient fertility of pot soil will also affect the growth and flowering of plants. therefore, nitrogen-based fertilizer should be applied 1-2 times during shoot shooting, and phosphorus-based fertilizer should be applied 2-3 times from flower bud differentiation period (from the end of May) to flowering.

The basin soil is too wet. Sweet-scented osmanthus avoid too wet and stagnant water, waterlogging will cause rotten roots and lead to poor growth and non-flowering, serious will also cause the death of pot plants. Watering should follow the principle of "no dry, no watering, watering thoroughly", and the stagnant water in the basin should be removed in time after heavy rain and torrential rain.

The soil is alkaline. Sweet-scented osmanthus likes slightly acidic soil, and the suitable pH value is 5.5-6.5. Sweet-scented osmanthus, which grows in alkaline soil, often grows badly and affects flowering.

Smoke pollution. Sweet-scented osmanthus is not resistant to smoke and pollution. After too much smoke or pollution, the leaves will become smaller and fall off easily, and there will be only long leaves and no flowering.

Under the age of flowering. Sweet-scented osmanthus will not blossom before it blossoms.

Why potted sweet-scented osmanthus does not blossom? the propagation of sweet-scented osmanthus is mostly cuttings and grafted seedlings, and the flowering time is short. 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. But found that some sweet-scented osmanthus still do not blossom, this is why? The main reasons why sweet-scented osmanthus can not bloom are as follows: first, enter the house prematurely, the temperature is above 10 degrees Celsius, 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. Second, after coming out of the room in spring, the wind and the sun will dry the leaves, so it is not easy to blossom even if they send out new buds again. Third, 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. Fourth, lack of light. Sweet-scented osmanthus needs more than 10 hours of light, otherwise the leaves are not luxuriant, affecting flower bud gestation and not blooming. Fifth, too much watering. Cause rotten roots, fallen leaves, affect flowering. Sixth, too much nitrogen fertilizer. Make the branches and leaves grow and affect the flowering. 7. Smoke and oil dirt pollution. Sweet-scented osmanthus is not resistant to soot and oil dirt, and its leaves have been polluted by soot and oil for a long time, resulting in poor growth and even leaf shedding, affecting flowering. 8. Lack of pruning. Osmanthus fragrans 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. In order to make potted sweet-scented osmanthus blossom, corresponding countermeasures should be taken according to the reasons for non-flowering. First, 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. Second, 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 gradually adapt to the outdoor environment. Third, to ensure long sunshine, there should be more than 10 hours of sunshine every day to meet the needs of sunshine. Fourth, rational watering. Should maintain 30% water content, hot summer, 60% water content is appropriate, not too dry and too wet. Fifth, nitrogen fertilizer should not be too much, and 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% Murray 0.2% potassium dihydrogen phosphate is sprayed on the leaves. Sixth, 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. Seventh, the basin soil should be changed if the basin soil is too long. 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. 8. Proper pruning. 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.
