Breeding method of Dutch iron 1. Base:

Iron-loaded soil has strong adaptability and is not strict with soil requirements, but slightly acidic soil with loose fertility and good drainage grows best. It can be mixed with loam and river sand with high humus content under pine and cypress forests, and can also be mixed with humus and river sand. In the process of cultivation, ferrous sulfate needs to be applied once a month to ensure that the soil PH value is suitable and slightly acidic, which is suitable for its normal growth.

Breeding method of Dutch iron 2. Temperature and humidity:

The growth rate of iron is average, and the requirements for temperature are wide. The optimum growth temperature is between 15-30℃, and it should be kept above 2℃ in winter, so it is not resistant to severe cold. In the growing season, it is necessary to maintain a certain air humidity, for example, when the temperature is 20℃, the humidity is about 50%, and when the temperature is about 30℃, the humidity needs to be adjusted to about 70% to maintain a good growth momentum.

Breeding method of Dutch iron 3. Lighting:

The growing environment needs sufficient lighting conditions, but the scorching sun in summer needs about 50% shading. In the case of sufficient light conditions, the leaves will be thick and dark green, full of vitality, and can also tolerate the semi-shade environment, but it is not advisable to stay in the semi-shade environment for a long time, otherwise the leaves will droop easily and appear listless. In a cool environment, the growth is not good, the new leaves become tender and the color turns yellow and green, so it can only be placed for a short time.

Breeding method of Dutch iron 4. Watering:

During the growth of iron, it is necessary to keep the basin soil moist and slightly drought-resistant. Generally, watering can be done when the surface of the basin soil is "white". When the room temperature is lower than 15℃ in winter, it should be kept dry, and the basin soil should be watered after drying. During outdoor or balcony maintenance in high temperature period in summer, the basin soil should be kept moist to avoid yellowing and withering of leaves caused by drought.

Breeding method of Dutch iron 5. Fertilization:

Dutch iron does not need much fertilizer. When the growth is accelerated in spring, the compound fertilizer based on nitrogen fertilizer should be applied once a week, thin fertilizer can be applied in summer at high temperature, and more balanced fertilizer can be applied in autumn to increase the resistance of plants. Fertilization is needed when the temperature is suitable in winter, and it should not be applied when the temperature is lower than 15℃.

Breeding method of Dutch iron 6. Trim:

Because of its strong iron load and strong germination, pruning is very necessary for both piles and the whole company. Yellowing leaves need to be pruned in time, depending on the degree of yellowing. The light one only needs to cut off the edge or tip, and the heavy one needs to cut off the whole leaf. If the plant is not beautiful after years of cultivation, it can be reshaped by re-cutting, and the pile type can be left at the base of the branch for 2-3 cm or not; The whole plant can be re-pruned and shortened at the yellow-brown old branches to promote multiple branches and achieve the purpose of beautiful and full plant shape. The height of the stub depends on needs or personal preferences.

7. Propagation: The family generally adopts the combination of cutting propagation and pruning, which can be carried out indoors from April to August every year, all year round, but the temperature should be kept between 20-30℃ to facilitate the growth of new roots. It is best to break the pile type by hand, take off the lower 1/2-2/3 blades, and insert them directly into clean river sand for water permeability and temporary protection from light; After short cutting, the whole company should also remove leaves first, and then cut into clean river sand to make it permeable. After that, keep the air humidity at about 70%, and grow new roots and become new plants after one month.

8. Pests and diseases: Dutch iron has strong adaptability and few pests and diseases, but in high temperature environment, the tip or edge of the leaf is prone to appear dark brown, which will spread to the whole leaf in severe cases and need to be pruned in time, which is suitable for reducing the ambient temperature. Spraying broad-spectrum fungicides, such as carbendazim, thiophanate-methyl, chlorothalonil, etc. , the effect is very good. Scale insects are the main pests. Because the branches and leaves of Dutch iron are easy to take care of, it is best to manually wipe them at the early stage of pest occurrence, which is both environmentally friendly and effective.
