How do sweet-scented osmanthus trees fertilize? when are sweet-scented osmanthus trees grafted?

Sweet-scented osmanthus is one of the top ten traditional flowers, and it is also a common flower plant. In the past, sweet-scented osmanthus was an important raw material used by people to make cakes, but now its evergreen and sweet-smelling characteristics make it an indispensable role in family flower culture. In order to make sweet-scented osmanthus grow stronger, fertilization is a key step.

How to fertilize sweet-scented osmanthus trees

1. Choose fertilizer

In different growing periods of sweet-scented osmanthus, different fertilizers are also needed, generally speaking, phosphate fertilizer, nitrogen fertilizer, potash fertilizer and phosphate-nitrogen fertilizer are needed.

2. The period of fertilization

Sweet-scented osmanthus is in the period of growing branches and buds in early March, so it needs a lot of fertilization. during this period, applying nitrogen fertilizer to sweet-scented osmanthus contributes to the growth of new branches and buds of sweet-scented osmanthus, so that the flower buds grow rapidly and help blossom.

3. Fertilization methods in different periods

After late May, because the branches and leaves of sweet-scented osmanthus have grown and mature, sweet-scented osmanthus needs to accumulate nutrients, and phosphorus and nitrogen fertilizer should be applied to sweet-scented osmanthus at this time. After October, because sweet-scented osmanthus will continue to grow and need nutrients for photosynthesis, nitrogen-based phosphorus and potassium fertilizers will be added during this period. After the beginning of winter, sweet-scented osmanthus should be moved to indoor conservation. After moving indoors, cake fertilizer should be applied on the surface of the soil to let sweet-scented osmanthus spend the winter.

4. Nursing after fertilization

Sweet-scented osmanthus should be irrigated with enough water after fertilization, and put it in a warm and sunny place.

5. Points for attention

Be careful not to apply fertilizer in high temperature weather, high temperature weather will make fertilizer hot, sweet-scented osmanthus should not apply hot fertilizer, so avoid high temperature weather fertilization, it is best to apply fertilizer in the evening when the temperature drops.

Do not apply thick fertilizer to sweet-scented osmanthus, you only need a small amount of fertilizer and more water when applying fertilizer. Do not apply raw fertilizer to sweet-scented osmanthus, use corroded fertilizer, otherwise it will burn the roots of sweet-scented osmanthus. Do not apply fertilizer directly to the root each time to avoid burning the root and affecting the growth of sweet-scented osmanthus.

When will Osmanthus fragrans be grafted

Grafting sweet-scented osmanthus trees is better in early spring, usually in April-June. At that time, it can be determined whether it will survive or not, which is conducive to management. Osmanthus fragrans can also be grafted in autumn, and the survival rate of master grafting is relatively high.

How does Osmanthus fragrans grow well

1. Appropriate provision of water

First of all, appropriate watering, to remember that the soil is not dry, do not water, irrigate the principle of watering to the end, every day to the leaf surface watering. In the hot summer, you must sprinkle water sooner or later, lest the plants have no water to drink, and in winter, sprinkle water around noon, the temperature of the water should be close to the temperature of the soil, do not be hot and cold, and pay attention to the fact that there is no stagnant water in the basin.

2. Replenish fertilizers in time

Reasonable fertilization, it is for the purpose of watching flowers, should be given adequate fertilizer. Urea can be applied to new shoots for 1-2 times, and phosphate fertilizer should be used mainly after flower germination and before flowering. The soil should be drier before using fertilizer. It is best to soften the soil so that the flowers can be better absorbed and watered again after a day.

3. Change the basin and soil on time

Change the basin and get some soil every 2 to 3 years to get rid of part of the old and withered roots to avoid the loss of unnecessary nutrients. A layer of carbon slag or roof tiles can be padded on the bottom of the flowerpot to facilitate ventilation and drainage, and the oil-pressed residue cake can be used as the basic fertilizer to spread the soil evenly when changing the pot.

4. Trim it into a good shape

Repair and plastic surgery, plastic surgery is generally a combination of qualitative and repair methods, it is best to be carried out after autumn, poorly shaped trees can be cut off most of the top branches at 2 / 3 or 3 / 4, plants with too many branches still need to be cut and thinned, and old, weak, sick and disabled branches need to be cut off after blooming.

5. the way to take care of it during the winter.

Then overwintering management, indoor overwintering temperature should be kept at 0-5 ℃, humidity should be kept at 50-80%. The exposure of light inside the house is very important in winter, especially before the buds recover in early spring, when there is plenty of sunshine for the potted plants to be removed from the room after the end of spring.

How to water sweet-scented osmanthus

1. 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 watering.

2. Water quality

When watering sweet-scented osmanthus, just use ordinary tap water, but leave the water in the sun for two or three hours. Water temperature: 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. In short, the difference between the water temperature and the air temperature of the day can be minimized.

3. Operation

Because the water demand varies from season to season, the amount of water should be measured according to the season when rewatering. 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.

4. Points for attention

Watering should be carried out before 10:00 in the morning, and the water temperature should be similar to the temperature of the day. Also pay attention to as long as 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.

Sweet-scented osmanthus likes a warm and humid growth environment, and the requirement for the soil is a well-drained, fertile, slightly acidic sandy soil, because the growth of sweet-scented osmanthus is more abundant than that of ordinary flowers and plants. Flower friends need to pay more attention to this when breeding.
