Brazilian iron trees like a humid environment, and what flower friends like to do most is watering, and it is difficult for beginners to control that degree of watering, resulting in too much water, resulting in stagnant water, which leads to the emergence of leaf yellow.

Solution: if the plot is not serious, loosen the soil, and then move the pot to a ventilated sunny place to let the water evaporate quickly; if the roots have been soaked, you need to remove the plant from the pot, then cut off the rotten roots and replace them with heart-pot soil to replant.

When the Brazilian iron tree grows indoors, if the water and fertilizer is proper, it will grow luxuriantly. In order to be beautiful, but also for the healthy growth of the Brazilian iron tree, it generally needs pruning. Once the pruning is not timely, and the novice watering is very difficult to control that degree, the result is too much water, resulting in stagnant water, resulting in the symptoms of yellowing of the leaves of the Brazilian iron tree.

Solution: when we encounter this situation, we should prune the branches and leaves in time, fertilize them and carry out careful maintenance. I believe we will soon be able to revive the green leaves.

Evergreen trees with erect stems, up to 6 meters high, long, fragrant leaves. Cultivated and ornamental varieties are: Phnom Penh Xianglong blood tree, Jinxin Xianglong blood tree. Families often cultivate molded plants planted in pots with large, medium and small plants. Originated in Guinea, Africa, it likes high temperature, humid environment and sufficient light, but it is also shady. The suitable temperature for growth is 20-30 degrees.

Fragrant dragon blood tree chic shape, elegant and warm leaves, more shade-resistant, suitable for family layout. The large fragrant dragon blood tree is arranged as the main scene, with other small plants. The small fragrant dragon blood tree can be arranged on the flower rack separately. Hydroponic cloth can also be placed on the flower rack.

2. Maintenance of the four seasons

(1) Spring is suitable to be arranged on the balcony facing east, south and west. When the temperature rises in spring, the small plant basin had better use sandy loam with fertile, loose and good drainage. Because the internal storage of nutrients and water in the stem of large plants, the demand for soil is not high. Garden soil with high sand content can be used for planting. The fragrant dragon blood tree likes sufficient light, and it should be cultivated in places with sufficient light at the beginning of spring. When the light is insufficient, the markings on the leaves are easy to fade to green and the leaves turn yellow. The end of spring is the season for fragrant dragon blood trees to grow new leaves, which should be arranged in places where the light is bright or in the morning and evening. When there is a strong light at noon, the new leaves are easy to aging, dark green, not conducive to viewing, and the new leaves are easy to curl and even burn. The fragrant dragon blood tree cultivated in the semi-shade has large new leaves and bright colors. After the new leaves grow, they can be arranged in places with sufficient light or in places with bright light. After the temperature rises in spring, attention should be paid to the management of water and fertilizer, small plants should keep the basin soil moist, molded plants should make the basin soil moist to dry, Xianglong blood tree should have higher requirements for air humidity and should maintain higher air humidity.

(2) it is suitable to be arranged on the balcony of the east and north in summer. When the summer temperature is high, the fragrant dragon blood tree should be cultivated in the bright light, because of the large evaporation, pay attention to the water supply, and pay attention to increase the spray times in order to improve the indoor air humidity.

(3) it is suitable to be arranged on the balcony facing east, south and west in autumn. After the autumn temperature is cool, the fragrant dragon blood tree can be gradually moved to a place with morning and evening light. Pay attention to the supply of water and fertilizer. As the air is dry in autumn, attention should be paid to spraying to improve air humidity. Attention should be paid to maintaining the temperature of the balcony after the temperature drops at the end of autumn.

(4) it is suitable to be arranged on the balcony facing east, south and west in winter. Xianglong blood tree is not cold-resistant, and the lowest indoor temperature is about 10 ℃ to survive the winter safely. The temperature should be kept above 10 ℃. When the temperature is too low (5 ℃), it is easy to cause defoliation. Low temperature is the main cause of defoliation or death of fragrant dragon blood tree cultivated at home. At this time, adequate light should be ensured, and the basin soil should be moist and dry, but it should be sprayed more to improve air humidity.

3. Pruning

When the single plant is too high, it can be cut short according to the height needed to maintain a certain temperature and humidity, and new buds will grow quickly under the incision. When the twigs on the assembled plants are too long or the leaves are aged and off, the old stem can be cut short and the top is sealed with wax or paint to maintain a high temperature and humidity, and new branches and leaves will grow under the saw mouth.

The skills of planting flowers in October

First, the light should be sufficient

Some light-loving woody flowers that bloom in summer, such as jasmine, Fusang, Jiuli incense, etc., should still be placed in a sunny place, so that the plants can fully receive light, so that the leaves can better carry out photosynthesis, provide nutrients in time, and promote the maturity of branches in the current year. so that it can survive the winter safely and ensure that flowers and leaves still flourish in the coming year. Potted flowers such as rhododendron, magnolia, cyclamen, poinsettia and crab claw orchid that bloom before and after the Spring Festival should also be placed in a sunny place and receive full sunshine, otherwise the flowering period will be postponed or even will not bloom. General foliage plants are more shady, can give some light properly, but to avoid noon strong light.

2. Water and fertilizer should be appropriate

In early autumn, especially in the first and middle of September, the temperature is still high and the transpiration of plants is large. Most flowers should be watered once a day or two, and the amount of water should be controlled and fertilization should be stopped from the middle to late September, so as to avoid rotting roots and growing branches and leaves. Affect overwintering. Some flowers that bloom before and after the Spring Festival, such as cyclamen, orchid, crab claw orchid, rhododendron, etc., have passed the dormant period and began to enter the peak growing season, so they should blossom continuously from autumn to the Spring Festival, and appropriately increase phosphorus and potassium fertilizer. to facilitate flower bud formation and bud flowering.

Third, pruning should be reasonable

In addition to flowers that bloom in early spring, most flowers, such as jasmine, crape myrtle and pomegranate, can be pruned in autumn and pruned at the end of autumn and early winter, so that plants can reduce nutrient consumption in winter, promote potted flowers to be strong, and bloom more in the coming year. Remove diseased branches, withered branches, over-dense branches and overgrown branches when pruning, so as to lay a good foundation for potted flowers to survive the winter.

IV. Disease and pest control should be thorough

Autumn is still the season with high incidence of diseases and insect pests, and plants are vulnerable to shell insects, red spiders, aphids, whitefly and other pests. Diseases include leaf spot, stem rot and so on. Before potted flowers enter the house, these diseases and insect pests must be treated thoroughly and never let them do harm to the house. If no diseases and insect pests are found, they can be sprayed to prevent them.

V. breeding should be timely

After the Beginning of Autumn, the temperature dropped, and some biennial grass flowers, such as pansy, carnation, melon and leaf chrysanthemum, hollyhock, etc., were good time to sow seeds.
