How long does it take for the ornamental plant iron tree to blossom? How do you raise it? What are the taboos?

Iron tree scientific name cycad, alias open fire banana, Phoenix tail banana, Phoenix tail pine, Phoenix tail grass, is cycads, cycads plants. Do you know how long it will take it to bloom? How do you raise it? Are there any taboos? Li Jianhua, a seedling grower in Suqian, Jiangsu Province, learned that iron trees generally blossom and bear fruit in the south for 10-20 years or so. In other areas, it is difficult to bloom because of low calories, and flowers usually last for about two months, and by four months, white fruit will grow, and after a month, the fruit will ripen and turn orange.

How to raise the iron tree?

1. Soil selection

Iron tree is suitable to grow in fertile, slightly acidic sandy soil. The cultivated soil can be prepared with 1 part of coarse sand and 4 parts of pastoral soil, 5 parts of rotten leaf soil and 1 part of fine stone grain, or 2 parts of sandy soil and 2 parts of rotten leaf soil.

Iron tree is an iron-loving plant, which can be mixed with a small amount of iron shavings when preparing culture soil, or iron shavings can be removed from the basin soil or buried in the basin in early spring. Iron gradually seeps in and is absorbed. 0.5% ferrous sulfate spray can also be used to supplement iron to make the leaves firm and green. Before planting, put 5 cm thick coarse sand or gravel as seepage layer, and use mature bean cake fertilizer as base fertilizer. After planting, pour water thoroughly and leave it in a cool place for half a month, then it can be used as an ornamental.

2. Fertilization method

Compound fertilizer or urea can be applied twice a month from May to October. Urea had better be diluted 1000 times with water to spray leaves, and foliar fertilizer should follow the principle of "eat less and eat more". The family's daily rice washing water should not be stained with oil and water. It should be filled with buckets and pots and irrigated with liquid fertilizer the next day, which has a certain fertilizer effect. During the growing period, Tieshu was fertilized with fertile and diluted bean cake every 20 days. In order to make the leaves moist and green, a small amount of ferrous sulfate can be added to fertilizer and water.

3. Watering method

After the temperature stabilized in late April, the irontree pot was moved outdoors, watered once, and then properly controlled for a period of time until the occurrence of new leaves. After the new leaves are unfolded, the lower withered and yellow leaves should be cut off to make the plants colorful. During the peak growth period in summer, it is watered every 1-2 days, and the rotten cake fertilizer or human feces and urine are applied once a month to maintain sufficient moisture and nutrition in the soil. After the beginning of autumn, the temperature gradually decreased and the plant growth slowed down, so it was appropriate to water the plant twice. Before Frosts Descent, he moved to Ningnei for the winter and twisted the watering system to keep the basin semi-dry.

The iron tree grows slowly and does not like flood, especially in spring, autumn and winter, the principle of wet and dry must be strictly observed, that is, after watering once, the basin soil should be watered again. Except for cloudy and rainy days in summer, water should be watered and sprayed to the leaves once a day, but stagnant water is avoided, otherwise rotten roots will cause death.

Watering work in spring and summer, watering can be a little more, in order to keep the soil moist, grow slowly after autumn, moisture should be controlled to maintain a certain degree of dryness in order to survive the winter.

4. Temperature requirement

The suitable temperature for the growth of iron tree is 20-30 ℃, but it is more resistant to high temperature and severe cold. In winter, about 5 ℃ below zero can still overwinter outdoors, and below 10 ℃ should be protected. The iron tree is afraid of snow, if it snows, it should be moved indoors or covered with plastic film, otherwise the old leaves will turn yellow at the beginning of the next spring and lose their ornamental value.

Tieshu prefers a sunny, humid and ventilated environment. The north can be moved outdoors in early April and in the greenhouse before Frosts Descent in November. The room temperature should be kept between 7 and 10 ℃, but it can also withstand the low temperature of 0.5 ℃ without freezing damage.

5. Lighting requirements

Tieshu prefers a warm, humid environment with plenty of light and should be placed in a place where the sun shines directly. However, potted iron trees are not resistant to hot sun exposure, especially the new leaves of iron trees are very easy to burn and turn yellow. Therefore, after the growth of new leaves and the height of summer, certain shading conditions should be given.

Iron tree is a positive tree species, it is best to keep it in a sunny environment. In the midsummer season, the sun is strong around noon, so it should be shaded properly. Especially in the process of new leaf growth, it should not be placed in strong light, otherwise the new leaf will appear scorched edge or withered tip phenomenon.

6. Pest control

① spot disease: fungal disease. In high temperature and rainy weather, the disease is easy to spread. The leaves are light brown spots at the beginning after infection, and then spread in a nearly round or irregular shape, with a diameter of 1mm to 5mm, resulting in orange death and fragmentation of the leaves. In terms of prevention and treatment, there is more water in summer, and the diseased old leaves should be removed in time. At the initial stage of the disease, 75% of Bai Yin Qing wettable powder 800 times liquid, or 50% Topurazine wettable powder 800 times liquid, about 10 days spray once, the effect is better.

② scale insects: planted and maintained on the balcony, the ventilation and light transmission is not good enough, and the leaves are often vulnerable to shell insects. Repeatedly rub the damaged leaves with alcohol. It can kill adults and larvae; soak rice vinegar with cotton balls and gently rub damaged leaves to kill shell insects.

What is the taboo of raising iron trees?

1. Avoid keeping it on the balcony

If you raise iron trees on the balcony, it will have a negative impact on the overall situation.

2. Do not hang red objects next to the iron tree

The role of red objects in fengshui is to exorcise evil spirits, to ward off evil spirits, to increase good luck, and to enhance health.

3. Avoid keeping in an environment with many people.

Iron trees do not blossom. Although we often see the iron tree blossom now, whenever the iron tree blossoms, it is the moment when the luck around us decreases significantly.

4. Indoor potted iron trees must not use clayey soil.

Iron trees like fertilizer, especially iron fertilizer. In order to keep the leaves moist, greenish, shiny and shiny, thin liquid fertilizer can be applied once or twice in late spring and early summer, and ferrous sulfate solution can be added. Broken iron shavings are often used as basic fertilizer among the people. In early spring, the broken iron shavings are put on the basin soil, and after normal watering and maintenance, the iron rust gradually seeps into the basin soil, which also has a certain effect.
