How to prune the branches and leaves of Dutch iron

Pruning time

1. Pruning after the beginning of winter

This is because the cold weather in winter has fewer bacteria and insect pests, and the pruned branches and leaves are not easy to be infected with diseases and insect pests. When pruning, you can cut off the dead old Dutch iron leaves from the bottom of the Dutch iron to the top, diseased leaves with sick insects, or more dense leaves, and try to keep some good old leaves.

2. Pruning before Qingming Festival

At this time, Dutch iron is still in the stage of recovery and growth, and the wound is easy to heal after cutting off withered leaves, and at the same time, it can also reduce the occurrence of diseases and insect pests.

II. Points for attention

When trimming Dutch iron, pay attention to the cross section should be slightly oblique, do not cut into a flat mouth, so as to prevent Rain Water from soaking, do not spray water to the Dutch iron wound, conditional people can use wax or red paint cut to prevent bacteria or insect pests from causing Dutch iron rot.

2. Reduce watering

Dutch iron must be well managed before cutting, so that Dutch iron can accumulate more nutrients to ensure that more branches can sprout, and should also be placed in a place with better light for photosynthesis. After all the branches and leaves have been cut off, Dutch iron should not be watered too frequently, and then gradually strengthen the fertilizer and water or normal management when the new leaves grow.

How does Dutch iron reproduce?

1. Cutting time

Dutch iron can be propagated by cutting, and cutting can generally be carried out throughout the growing season, but spring and autumn are the best cutting time. Cutting propagation can be combined with Dutch iron pruning.

2. Select Huiwei.

Dutch iron needs to choose appropriate cuttings when cutting. Generally, cut off the branches around 10cm-30cm and put them in a cool and ventilated place to dry. After the wounds of Dutch iron dry, they can be planted in clean river sand. Generally, they can take root in about a month. Note that the incision should be disinfected and covered with about 2/3 places of sand when inserted on the sand bed.

3. Cuttage maintenance

After Dutch iron cuttage, reasonable maintenance is needed, and the temperature needs to be kept between 20 ℃-30 ℃, which is beneficial to root growth. In the early stage of cutting, it is necessary to avoid direct sunlight and maintain a relatively high air humidity.

How to raise Dutch iron

1. Soil

Dutch iron has strong adaptability and lax requirements on soil, but the growth of loose, fertile and well-drained slightly acidic soil is the best, which can be cultivated by the mixture of rotten leaf soil and river sand.

2. Humidity

Keep the basin soil moist during the growing season to avoid excessive watering, causing stagnant water and rotting the roots and stems.

3. Fertilization

It is full of vitality and does not have high requirements for fertilizer. It is enough to apply liquid fertilizer 3 Mel twice a month during the peak growth period.

4. Lighting

Dutch iron growth requires plenty of sunlight, except for proper shade in hot summer, other seasons can grow in full sunlight.

5. Temperature

Xi Yang is also resistant to yin and can adapt to different light environments. The best temperature for growth is between 15-30 ℃, and it is best to keep it above 2 ℃ in winter. It is not resistant to severe cold.

What if the Dutch iron leaves turn yellow?

1. Temperature reason

Spring, summer and autumn are actually not a big problem, but it should be noted that this is a plant native to America, so it is best to keep the temperature above 10 degrees Celsius in winter to prevent the leaves from yellowing.

2. Improper watering

Stagnant water can lead to poor breathing of plant roots and failure of nutrient transport, which is yellowing and wilting on the leaves. Therefore, when watering, we must pay attention to uniform watering and control reasonable water quantity.

3. Too little light

It is a light-loving plant, it is best to light at a fixed time every day in the process of maintenance. The best time is about three hours. Lack of light for a long time is also one of the reasons for leaf yellowing.

4. Fertilization errors

When plants lack nutrients, there will be symptoms of slow growth and yellowing of leaves, while too much or too high concentration of fertilizer will cause the plant to suffer fertilizer damage, root burning, root damage, and the plant will naturally wilt and yellow. the solution is to apply fertilizer reasonably.

5. caused by diseases and insect pests

It is found that the diseases and insect pests should be treated with drugs as soon as possible, and the diseased leaves of the diseased plants should be cut off immediately to prevent spread and aggravation.

Pruning and leaf pruning is a problem that is easy to be ignored for the cultivation of Dutch iron, but timely pruning can not only maintain the beautiful value of plant shape, but also prevent the occurrence of diseases and insect pests to a certain extent. Therefore, we should pay more attention to this point in the process of breeding.
