Strategies for Dealing with Potted Osmanthus That Won't Bloom
A brief knowledge of green plants, introducing you to the common knowledge of flower cultivation, especially the introduction of osmanthus. Strategies for dealing with potted osmanthus that won't bloom, please see the detailed introduction below.
Potted osmanthus is mostly propagated by cutting or grafting, and the blooming period is short. Cuttings of osmanthus bloom in the fourth year, while grafted golden, silver, and red osmanthus may bloom in 1/5 in the second year, and the ever-blooming osmanthus blooms in the same year. However, in cultivation, many potted osmanthus do not bloom at the flowering time.
The main reasons for the failure of osmanthus to bloom are as follows:
1. Entering the room too early, with temperatures above 10 degrees Celsius, the osmanthus does not get enough rest. This causes the osmanthus to sprout and unfold leaves too early, consuming a large amount of nutrients. Combined with insufficient light and a weak plant, it affects flowering.
2. After moving out of the room in spring, the wind and sun cause the leaf tips to dry out. Even if new buds grow, they are not likely to bloom.
3. Insufficient nutrients. Osmanthus enjoys fertilizer, and some potted osmanthus have not been repotted or changed soil for several years, causing insufficient nutrition, the roots to become entangled, and affecting flowering.
4. Insufficient light. Osmanthus requires more than 10 hours of light; otherwise, the leaves will not be lush, affecting the formation of flower buds and thus flowering.
5. Overwatering. This causes root rot and leaf fall, affecting flowering.
6. Too much nitrogen fertilizer. This causes the branches and leaves to grow excessively, affecting flowering.
7. Pollution from soot and oil. Osmanthus is not resistant to soot and oil pollution. Long-term pollution of the leaves by soot and oil can lead to poor growth or even leaf fall, affecting flowering.
8. Lack of pruning. Osmanthus has a developed root system and strong germination ability. Without moderate pruning, the branches and leaves become too dense, affecting flowering.
To make potted osmanthus bloom, corresponding countermeasures should be taken based on the reasons for non-flowering.
1. Ensure low-temperature dormancy. The overwintering temperature for potted osmanthus is 3-5 degrees Celsius. There is no need to move it into the room above 3 degrees Celsius; maintain natural temperature. Below 3 degrees Celsius, move it indoors. Inside the room, allow it to hibernate at low temperatures to ensure robust growth and abundant flowers and leaves the following year.
2. When moving out of the room in spring, do so on a cloudy or rainy day. Avoid sudden exposure to strong sunlight on a sunny day and allow it to gradually adapt to the outdoor environment.
3. Ensure long-daylight hours, with more than 10 hours of daylight every day to meet the light requirements.
4. Water appropriately. Maintain 30% water content, and during hot summers, 60% water content is suitable. Avoid both excessive dryness and moisture.
5. Do not use too much nitrogen fertilizer and should be combined with phosphorus and potassium fertilizers. Osmanthus requires more phosphorus and potassium fertilizers and can be top-dressed with 0.1% to 0.2% phosphorus acid hydrogen potassium on the leaf surface.
6. Prevent pollution. Use fine gauze to gently wipe the leaves to keep the leaf surface clean. Wipe once every 15 days to facilitate photosynthesis and ensure the plant grows robustly.
7. Change the potting soil if it has been in use for too long. Change the potting soil every 1-2 years, and when repotting, a small amount of hoof slices can be used as a base fertilizer at the bottom of the pot.
8. Prune appropriately. Before moving out of the room, cut off the diseased and weak branches and dense branches. Also, trim moderately based on the plant shape to facilitate ventilation and light, promoting flowering.
The above strategies for dealing with potted osmanthus that won't bloom, these brief experiences in green plants and flowers, hope to bring you some help in life!
