How to plant Osmanthus fragrans seedlings? What if the leaves turn yellow? How do you water it?

Osmanthus fragrans is one of the ten traditional famous flowers in China. It is an excellent ornamental and practical tree species with greening, beautification and fragrance. The bonsai made with sweet-scented osmanthus is evergreen all the year round, the flowers are numerous and fragrant, and the ornamental value is high. If properly managed, it can flourish, blossom and fragrance, so how to plant sweet-scented osmanthus seedlings? What if the leaves turn yellow? How do you water it?

First, how to plant sweet osmanthus seedlings?

1. Colonization

Hole digging: the size and depth of the hole depends on the size of the soil ball at the root of the sweet-scented osmanthus seedling, generally, it should be able to completely cover the root of the sweet-scented osmanthus seedling, but it should not be too deep, because the sweet-scented osmanthus seedling will grow slowly. For example, the stem diameter of young sweet-scented osmanthus trees for 3 or 4 years is about 3 cm. At this time, the depth of the hole is 20-25cm, and the diameter of the hole is 30cm.

Application of base fertilizer: sweet-scented osmanthus seedlings need base fertilizer before transplanting (if the soil layer is fertile, it is OK not to apply base fertilizer). The base fertilizer should be farm rotten fertilizer, about 1000 grams per mu, and mix the base fertilizer with the surface loam. Fertilization should not be too much, because sweet-scented osmanthus seedlings are small, more should not be absorbed will cause root burning.

Pruning: before transplanting sweet-scented osmanthus seedlings, in order to reduce water evaporation, cut off some of the luxuriant branches and leaves of sweet-scented osmanthus seedlings properly; in order to stimulate rooting, you can also cut off some of the overlong roots, but do not hurt the main roots.

Planting: sweet-scented osmanthus seedlings should be planted in the southeast position is better, in order to maximize its acceptance of light. Sweet-scented osmanthus is not resistant to flooding, the height of planted sweet-scented osmanthus can not be lower than the height of the transplanting site, but also can be slightly higher. After planting, fill the soil of the hole firmly, and then water it once.

2. Nursing after planting

The nursing work of sweet-scented osmanthus seedlings after planting includes watering, weeding, pruning, pest control and so on. Please refer to the later maintenance work of sweet-scented osmanthus seedlings.

Several key points for planting sweet-scented osmanthus seedlings are as follows:

The cultivation environment of ① sweet-scented osmanthus seedlings should be ventilated, the sun should be sufficient, and the soil should choose fertile and acidic sandy soil.

Many people in ② are used to planting sweet-scented osmanthus in spring. In fact, scientific research shows that planting sweet-scented osmanthus seedlings in November, that is, in autumn, is better than spring planting in March-April.

③ should pay special attention to watering, drought prevention and frequent watering in high temperature and long drought season, drainage and waterlogging in rainy season, and timely watering of newly planted sweet-scented osmanthus.

④ pays attention to weeding in mid-tillage, which is especially powerful for the growth of sweet-scented osmanthus seedlings.

⑤ sweet-scented osmanthus seedlings can apply basal fertilizer when transplanting, and can apply compound water and fertilizer properly after transplanting, applying 30kg per mu. In the future, there is no need to apply fertilizer within a year, and after a year, we should apply thin farm manure as the principle, and apply thin fertilizer frequently.

⑥ shaping and pruning, sweet-scented osmanthus is a more resistant to pruning flowers and trees, if you want to directional cultivation, sweet-scented osmanthus seedlings in the period of directional pruning.

Second, what if the leaves of sweet-scented osmanthus turn yellow?

1. Appropriate temperature

15-28 ℃ is the optimum temperature for sweet-scented osmanthus to grow. The summer temperature is too high. If it is not cooled down or still exposed to the sun, its leaves will easily turn yellow. If the winter temperature is too low, if we do not take proper heat preservation measures, it will also cause its leaves to turn yellow. Therefore, when raising sweet-scented osmanthus, we should pay attention to cooling in summer, put it in a more cool place, keep warm in winter, and move it indoors.

2. Reasonable watering

This kind of flower is not resistant to waterlogging. once it is watered too much, it is easy to cause its rotten roots, which will inevitably lead to yellow leaves. Therefore, when planting this kind of plant, we must choose loose soil with good drainage. In addition, daily watering should not be too frequent, nor should we water too much at one time. Just water the basin soil after it is dry.

3. Correct fertilization

If less fertilizer will lead to the yellow leaves of this plant, so we should reasonably apply fertilizer, liquid fertilizer and compound fertilizer during its growing period, but we should pay attention to the concentration should not be too high. In addition, we should change the basin and soil in time to ensure that the soil is not hardened and that there are enough nutrients in the soil. It is worth noting that there is no hurry when applying fertilizer, too much fertilizer or too much concentration at one time is not conducive to its growth, and even cause it to burn roots and yellow leaves.

4. Change the soil quality

Relatively speaking, it prefers acidic soil. If the soil is alkaline or alkalized, the leaves of this plant may turn yellow. To keep the soil acidic, you can add a little ferrous sulfate or leftover beer when watering. Also note that both ferrous sulfate solution and beer should be diluted and the concentration should not be too high.

How to water sweet-scented osmanthus?

Watering sweet-scented osmanthus should also pay attention to feasible methods in order to make sweet-scented osmanthus grow more quickly and healthily.

First of all, sweet-scented osmanthus watering time: in spring and summer hot weather often watering, watering must be watered before 10:00 every morning, to the winter dry and cold season, reduce the amount of water.

Secondly, the quality of watering: when watering sweet-scented osmanthus, just use ordinary tap water, but leave the water in the sun for two or three hours.

Water temperature for sweet-scented osmanthus: in order to keep the water temperature consistent with the soil temperature, in case the water temperature is lower than the soil temperature, it will hurt the roots, so it is best to water before 10 o'clock in the morning, anyway, the difference between the water temperature and the air temperature of the day can be minimized.

Finally, there is the operation of watering: because the water demand varies from season to season, the amount of water should be measured according to the season. Summer is the hottest, so summer watering should be carried out before ten o'clock, or after four o'clock in the afternoon, twice a day, slowly or by spraying. If you encounter high temperature, it is necessary to spray water on the leaves of sweet-scented osmanthus to keep the plant moist.

After watering, it is best to loosen the soil to help the roots absorb enough water and promote growth.

Fourth, what should sweet-scented osmanthus be watered?

Sweet-scented osmanthus watering has many aspects to pay attention to. The first watering time should be carried out before 10:00 in the morning, and the water temperature should be similar to that day's air temperature.

Sweet-scented osmanthus watering should also pay attention to as long as to ensure the moisture of the soil, do not accumulate water, so as to avoid rotting roots.

Water frequently in summer and just after planting, especially the seedlings should be watered thoroughly to promote the growth of seedlings.
