If you want osmanthus to grow well, fertilization is very important. How should you fertilize osmanthus?

Osmanthus is a kind of flower beloved by flower friends. Golden autumn season, who is not intoxicated by its fragrance? A few osmanthus flowers are the best way to learn about life. Osmanthus flowers want to grow well, reasonable fertilization is inseparable. Many planting osmanthus friends will ask, osmanthus should be how to fertilize!

There are three very important fertilization stages in the growth of osmanthus fragrans, which are spring germination stage, summer bud differentiation stage and autumn and winter overwintering stage. Good fertilization measures in these three periods can ensure the healthy and stable growth of osmanthus fragrans and promote the flowering of osmanthus fragrans.

First, don’t fertilize too early in the spring. In general, it can be applied in the warm months of March before new buds sprout. At this time, fertilization can promote osmanthus to send out new branches and shoots. Fertilization is mainly nitrogen fertilizer. Of course, in order to facilitate nutrient absorption, decayed animal waste can be used at the same time, such as pig manure, chicken manure and so on. Indoor cultivation, afraid of a strong smell, can be nitrogen fertilizer and decadent cake fertilizer and other mixed use. Be careful not to overuse, so as not to burn the roots.

In the growing season, some liquid fertilizer can be used. July is the second important period of osmanthus fertilization. Fertilization during this period can improve the ability of osmanthus to withstand high temperature and drought, accumulate nutrients, which is conducive to flower bud differentiation and make golden autumn have more flowers and fragrant flowers. It can even be said that the fragrance of osmanthus in autumn depends on this fertilization!

This kind of fertilization can be mixed with phosphorus and potassium fertilizer and organic fertilizer. It is emphasized that priority must be given to the application of phosphorus and potash fertilizer for the benefit of autumn flowering. At this point, we can mix phosphorus and potassium fertilizer with decomposing manure with good results. Of course, you can also spray potassium dihydrogen phosphate mixed with good quality rice vinegar to protect the leaves and promote flowers.

The third important fertilization is in October. Fertilization in October can replenish the nutrients consumed by flowering and accumulate nutrients, which is conducive to the overwintering of osmanthus flowers. At this time, organic fertilizer is mainly used for fertilization, such as decomposed pig manure, sheep manure, cow manure, and a small amount of compound fertilizer is added, which is more conducive to the nutrient demand of osmanthus fragrans.

For osmanthus flowers, proper fertilization is very important. It can usually only be provided in the case. However, a moderate amount of fertilizer should be applied. Before the bud differentiation and flowering of osmanthus fragrans, a small amount of dry osmanthus fragrans can be applied 1-2 times nitrogen fertilizer, nitrogen, phosphorus, potassium fertilizer. Osmanthus flowers will not grow well if fertilized improperly. Potted osmanthus is easy to grow sparsely due to insufficient fertilizer, or deformation due to excessive fertility, affecting the overall shape and reducing the appreciation value. Therefore, we must pay attention to timely, appropriate and on-demand fertilization.

Timely: Potted trees or trees with fresh mud have damaged roots and are not suitable for fertilization for the time being. Fertilize as soon as normal returns in spring or early summer. After flowering in autumn, the growth rate of potted trees gradually slows down, so less fertilizer should be applied.

In winter, most potted trees are dormant, so fertilization stops. For potted trees placed on balconies, if fertilization is needed, it should be done at night on a cloudy or sunny day. First, clean and loosen the weeds in the pool, then water it again in the morning.

Appropriate amount: The amount of fertilizer applied to potted trees should follow the principle of rare and frequent application. From spring to autumn, dilute liquid fertilizer is generally applied every 10-15 days, with a ratio of about 3:7 to water. Or according to the growth of potted trees appropriate increase or reduce the number of topdressing, and adhere to each time not too much or too thick.

As needed, nitrogen fertilizer promotes leafy foliage, phosphorus fertilizer promotes firmer flowering, and potassium fertilizer promotes root and stem growth. Application effect is different. It should be based on potted plants. According to the specific needs to choose osmanthus growth characteristics, growing season and ornamental requirements.

Fertilizing osmanthus flowers is also taboo. Fertilization during dormancy is CONNO-NO: THE upper part of the rhizomes grows stagnant during dorMANcy, but still maintains normal metabolism, with weak respiration and transpiration. The roots grow slowly, but the absorptive capacity becomes weak. At this point, fertilization can cause “root asphyxia.”

For example, people have to force-stuff after eating, but they can’t digest the fact. In this way, it is easy to cause root nitrite poisoning and root damage. Plant roots have a self-protection system, and the damage of roots will start the self-protection of branches and leaves nutrients, leading to physiological drought death of plants.

Avoid APPLYING heavy fertilizers during flowering: THE water absorption of plants that require large amounts of water depends on osmotic pressure. If fertilized at this time, it will destroy the osmotic pressure function inside and outside the fibrous root, resulting in the difficulty of water absorption of the root system, and flowers will swell and wilt due to lack of water.

Nitrogen should be avoided before stopping growth in autumn: nitrogen mainly plays a role in promoting vegetative growth. Before stopping growth in the fall, water and fertilizer should be deducted to ensure that the shoot stops growing in time. Ensure that plant tissues are rich and accumulate nutrients in preparation for hibernation, sperm storage and rapid accumulation. On the contrary, if nitrogen fertilizer is applied again, the shoot will continue to grow, resulting in loose tissue and vulnerability to freezing damage.
