Why does Milan flower not bloom?

Why Milan flowers do not bloom, Milan is also known as Milan orchid or tree orchid, yellow flowers like millet grains, rich fragrance, loved by people. Although the fragrance of Milan is not as elegant as that of orchids, it is better than night incense and so on.

Growing Milan mainly appreciates its fragrance. When growing Milan, we often encounter the phenomenon that the branches and leaves are luxuriant but do not blossom, or the rice-like buds do not open and fall, and even the flowers lack fragrance. Why?

Milan is native to Guangdong, Guangxi, Taiwan and Southeast Asia, and likes a relatively humid and warm climate. Therefore, the warm and humid conditions must be satisfied during the initial culture, not in the sun, watering should be moderate, more nitrogen fertilizer such as urea should be applied for plant vegetative growth, and after the plant has grown, more phosphate fertilizer such as superphosphate should be applied, otherwise, from vegetative growth (branch and leaf growth) to reproductive (bud flowering) growth stage, flower buds will not be formed due to lack of nutrients to promote flowering. After the emergence of buds, to continue to provide phosphate fertilizer, watering should not be too much, too much water is one of the reasons for falling flowers.

Sometimes too dry will cause the leaves to curl, dry or even fall off, which is disadvantageous to flowering and should be watered according to the climate. When the temperature is high, the air flows quickly and evaporates quickly, and the basin soil is easy to dry and can be watered more, or spray water on the leaf surface and the ground to increase humidity. When there is too much water in the basin, it is easy to cause root rot. If the conditions for flowering are met, that is, sufficient fertilizer and moist environment, it will continue to appear yellow florets on the new branches, otherwise even if a small amount of flowers are produced, their fragrance will not be obvious.

If there is no problem with fertilizer and water and does not blossom, you must carefully check the back of the leaves and branches for moving brown dots, which seem to be motionless brown dots (shell insects), attached to leaves or branches and constantly sucking nutrients from the plant. Over time, the leaves will continue to fall off, or even die one branch after another, until the whole plant dies. In this case, you should spread paper on the basin soil, brush off the worms one by one with a small toothbrush, and then burn the paper. Agents that can be sprayed to kill it are usually highly toxic. In general, it is not suitable to choose, nor can it be bought from a florist or pesticide shop. the above is an introduction to why Milan flowers do not bloom.

Why does Milan blossom not fragrant?

Why Milan flowers are not fragrant? the reason why Milan flowers are fragrant is that they have oil cells that produce fragrance, which can constantly secrete aromatic oil through the oil glands, while the amount of aromatic oil emitted mainly depends on the temperature and the intensity of light. the reason why Milan blossoms are not fragrant.

① summer is the peak growing season, long-term shade and less light, coupled with the application of nitrogen fertilizer or too much watering, will result in no flowering, less flowering or weak fragrance.

② is watched indoors for a long time in summer, because the indoor sunlight is too weak or too dark, so the growth is poor, the plant is thin and the branches and leaves are sparse, which can result in only long leaves and no flowering.

③ suffered from red spiders and shell insects, resulting in brown spots on new branches and old leaves, or white insects, resulting in a large number of fallen leaves and flowers and died.

When the sun is sufficient and the temperature is higher than 30 ℃, the aromatic oil gives off quickly and the aroma is strong. On the other hand, Milan can blossom when the light is insufficient or the temperature is low, but the fragrance is not strong, or even no fragrance. Milan blossoms in late autumn and early winter, if placed indoors, the light intensity is obviously not the same as summer, the light time is also short, coupled with the low temperature, the flowers will naturally have no fragrance. At this time, Milan can be placed outside and given plenty of sunshine, and at the same time, certain light and temperature should be added indoors to make it grow normally and produce flowers with strong fragrance. the above is an introduction to why Milan blossoms are not fragrant.

Why does Milan blossom not fragrant?

Why Milan blossoms are not fragrant, Milan, there are usually two kinds of large leaves and fine leaves, the aroma of large leaf species is very light, and the aroma of fine leaf species is thicker. In addition to the characteristics of varieties, cultivation conditions often affect the distribution of aroma. If the phosphorus and potassium fertilizer is applied before flowering, and there is often sunlight scattering, and the water is moderately drenched, its aroma will be thicker when it blossoms; if more nitrogen fertilizer is applied before flowering, or if there is too much shade or too much moisture, the fragrance of the flowers will be very weak. Milan is generally potted, and its seedlings must have intact roots and soil masses before they can be cultivated.

Pots or soil can be changed in spring, summer and autumn. Sun-dried pond mud is often used in the south, while acid culture soil or noodle sand is needed in the north. It is required to use fertile culture soil, which can be mixed with 25% rotten leaf soil, 50% compost and 25% river sand. The bottom of the basin should be padded with more tiles or a small amount of fully rotten biscuits to facilitate drainage.

Put the upper basin under the shade shed for maintenance, spray water to the leaf surface once or twice a day (less water should be watered in half a month), wait for the new shoot to occur, and then move to the place where you can see the light for maintenance. The new potted flower seedlings began to apply thin sesame paste residue water before and after the Beginning of Autumn, and from the second year on, topdressing once every 20 days in the peak growing season. If 1000 times of potassium dihydrogen phosphate was applied at intervals, the flower would bloom more luxuriantly. The basin soil should always be kept moist. In winter, enter the medium temperature greenhouse to overwinter, make them see direct light, and pay attention to ventilation, generally put on the high platform near the south of the greenhouse, the room temperature should not be less than 10 ℃, water should be less irrigated and stop topdressing, but also to prevent the invasion of shell insects. Move it outdoors from late April to early May next year and put it in the leeward for maintenance.

Milan should pay attention to plastic surgery from the beginning of Miao, keeping the trunk of 15cm to 20cm. The lower branches of perennial plants often grow old and die, so they are cut once a year or every other year to promote the germination of more lateral branches. The fragrance of Milan flowers lingers for a long time. The high pressure strip method can be used to propagate in the south. In the north, peat and flour sand are mixed in late May to do cutting substrate for tender wood cuttings, strictly moisturizing with plastic film. After the Beginning of Autumn, the rooting rate can reach about 60%, and the seedling growth is very slow. The above is an introduction to why Milan blossoms are not fragrant.
