I believe everyone is familiar with the iron tree, iron tree is a relatively common ornamental plants, also known as fiddletail banana, fire banana, fiddletail pine, golden fruit, iron banana, fire banana, banana, is a very slow growth, very long life green leaves. Iron trees also bloom, usually after ten or twenty years, so millennium iron trees also bloom. Now potted iron trees are loved by everyone. Let's take a look at how potted iron trees are raised.

I. Soil conditions

Cycads love sunshine and are tolerant of half shade. It grows well in warm, humid and fresh air conditions. Intolerant of cold, the north of the Yangtze River basin are potted. Potted in the north, spring and autumn should avoid the scorching sun, hot rainy season should avoid pot soil ponding long wet. Acid soil is needed, and leaf yellowing symptoms often occur when alkaline soil is used. Fertility tolerance is strong, growth stops in poor soil, and new leaves often do not sprout for many years. Cycads grow slowly, usually only 1 cm to 2 cm long stems per year, life expectancy of up to 200 years.

Second, the choice of potted containers

For the selection of potted containers for iron trees, we need to choose several types. In addition to choosing acidic soil, loose and fertile soil is also necessary. Therefore, when adding pot soil, we should also add the following slightly acidic sand. There should also be holes at the bottom of the flower pot. This can facilitate drainage and allow the roots to absorb sufficient air. Cycas do not need to change pots frequently. Generally, it can be changed once every two or three years. When changing pots, choose some new soil to put in. Can be conducive to its growth, topdressing when we choose organic liquid fertilizer on it.

III. Points of watering

The water quality in the south and the north is different. The south can be watered directly, while the water quality in the north is alkaline. Therefore, ferrous sulfate solution needs to be poured every half month. In summer, the soil should be kept moist. In winter, it should be maintained indoors. Generally, it can be put outdoors only in the spring of the following year. If put in medium temperature or high temperature greenhouse winter, early spring germination of new leaves, it must wait until the spring dry wind can be moved to the outdoor, put under the shade maintenance, to all new leaves after the healthy, and then moved to the sun, otherwise the new leaves easy to scorch damage.

IV. Fertilization methods

Potted iron tree growth period 5~10 months can be applied compound fertilizer or urea 1~2 times a month. Urea is best diluted with water 1000 times spraying leaves, should follow the principle of "eat less and eat more".

V. Pest control

Iron trees often have some pests on them, and many of them are hidden on the back of the leaves, which is not easy to find, resulting in yellowing of the leaves. At this time, you can wash them yourself, or pour some ferrous sulfate solution, keep ventilation, and avoid coal pollution.
