How to turn yellow of threaded iron leaves? how to reproduce threaded iron?

Threaded iron is a relatively beautiful and generous plant, and it is a green plant that often appears in public places. It has a good effect on air purification and beautification of the environment. However, the beauty of threaded iron should be based on its evergreen seasons. Once the leaves of threaded iron turn yellow, it may affect the beauty of threaded iron.

What if the threaded iron leaves turn yellow?

1. Poor threaded iron plants lead to yellowing of leaves.

In the cultivation of threaded iron, it is very important to choose good plants. If you accidentally choose the threaded iron that is not growing well, it may cause the leaves to turn yellow. When choosing threaded iron, choose healthier growth, stronger branches, and then no damage to the leaves or yellow leaves, better.

2. The growth environment of threaded iron leads to the yellowing of leaves.

When raising threaded iron, the unsuitable growth environment is also an important reason for the yellowing of threaded iron leaves.

Threaded iron likes a high-temperature, humid and semi-overcast growth environment. When breeding, it is necessary to meet these environmental needs of threaded iron, such as too low temperature, or sun exposure, and so on. It will cause the threaded iron leaves to turn yellow and wither and the leaf tip to turn yellow.

3. Long-term stagnant water in threaded iron flowerpots leads to yellowing of leaves.

When raising threaded iron, it is necessary to maintain a moist environment, so some people can't help watering it hard, which is likely to lead to stagnant water in the threaded iron flowerpot for a long time, and the roots can not breathe, making it rotten rot. it will cause its leaves to turn yellow. Therefore, when raising threaded iron, we must reasonably water it, pay attention to drainage, and observe the growth of threaded iron at any time to avoid the phenomenon of rotten roots.

4. iron deficiency in threaded iron leads to yellowing of leaves

When raising threaded iron, there is another possibility that the plant lacks iron, which can also cause its leaves to turn yellow. At this time, you can spray some ferrous sulfate solution to the threaded iron, usually once in 10 days or so, two or three times in a row, and the leaves will turn green again.

Propagation method of threaded iron

1. Cutting propagation of threaded iron.

The suitable cutting time of threaded iron is generally between March and October. When cutting, put the bud eyes of the cuttings up, tilt slightly into the box surface, and the cutting depth is about the cutting depth of 1, 2, 2, 2, 3 of the cuttings.

2. Management of threaded iron cuttings

It needs to be watered immediately after insertion. The best moisture content of the cutting substrate is about 60%, and the relative humidity should be maintained between 80% and 90%. Pay attention to replenish water in time. Generally speaking, the callus can be formed after half a month, and the amount of water can be gradually reduced in order to take root.

It is better to keep the air temperature lower than the substrate temperature 3 ℃ 6 min, and film can be used for cooling and moisturizing. The suitable temperature for rooting of cuttings is about 20 ℃ and 25 mol. If the temperature is above 30 ℃, ventilation should be carried out at noon and water spray should be used to cool down.

After insertion, it should be sprayed with 65% mancozeb, or 50% carbendazim 800 times, usually every 5 days, especially after rain. After the cuttings take root, the times of spraying can be reduced gradually. When the callus is formed, foliar topdressing needs to be carried out once a week, and 0.2%-0.5% urea and potassium dihydrogen phosphate can be sprayed in the later stage.

3. Cutting seedling cultivation techniques of threaded iron.

After growing for half a year, the cuttings can be transplanted when their length is about 15ml / 20cm. The transplanting is generally carried out in spring and autumn, and the suitable time is between February-May and September-October. When transplanting, you should choose 60% Rich 70% shade density, water, stone with moss to plant, can improve the survival rate. Generally, it is best to use the clamp method for cultivation, press the threaded iron root system with steel nails, then clean up the root system, retain other moss, increase water content, and then improve the survival rate.

Pruning method of threaded iron

When you trim the threaded iron, you actually cut off the roots that have already been part of the branches and leaves. Before planting, the root of the threaded iron can be trimmed properly to cut off what is rotten and what is broken. Branches and leaves also need to be pruned properly, which can be cut off by 1/3 or 1/2, so that the transpiration of the plant will be reduced and it will be easier to survive.

Secondly, when trimming the threaded iron, we also need to maintain its basic tree shape, so as to facilitate future modeling, if the pruning is too strong, it may not make the plant shape beautiful.

Will the threaded iron bloom?

Threaded iron will blossom. Threaded iron leaves are very large, slightly curved thread style, threaded iron flowers will grow in the middle of the leaves, the stem is very thick, the bud is dense on the central stem, a bit like the shape of corn. The flowers of threaded iron are white and give off a very strong fragrance when they bloom. Because threaded iron is a tropical evergreen shrub, it usually does not blossom when planted indoors, so it is very rare to see it blossom.

Threaded iron is a kind of foliage plant, so the partners who plant threaded iron should give priority to the beauty and cleanliness of the leaves. As for whether the threaded iron blossoms, we should not expect too much, but once it blossoms, we should take more careful care of the threaded iron to ensure the normal growth of threaded iron.
