What is the reason for the slow growth of orchids?

Whether the root system of the orchid is healthy, whether it can absorb nutrients normally, and the health of the root system is affected by the proportion of the soil, if you want to make the orchid grow better, the soil must ensure that it maintains a slightly acidic state, and at the same time it is breathable and fertile, so that the root system of the orchid can be raised white and strong, and absorb more nutrients. After receiving the orchid, check the condition of the soil first, if the soil is compacted or relatively poor, it is recommended to replace it with new soil, we can use humus soil, or fermented pine needle soil, this kind of soil is slightly acidic, and contains nutrients, which can promote root growth, in order to improve the permeability of the soil, we can also mix three to four percent of the red bricks, volcanic rocks, phytolites, etc. in the soil; However, during the growth of orchids, there will always be alkalinization, so it is necessary to add ferrous sulfate regularly to maintain soil acidity.

Every 20 days or so, you can add ferrous sulfate to the orchid once, maintain the slightly acidic state of the soil every 1 to 2 years, it is best to change the pot of the orchid once, and the soil should be combined with soft and hard to ensure that the soil is hydrophobic and breathable, such as using pine needle soil, adding cinders of hard planting materials, planting stones, wood chips of soft planting materials, water moss, etc., fully mixed. Orchids like a moist growth environment, if your orchid leaves have been shriveled or slender, the state is very general, it is likely to be caused by insufficient air humidity, so we in the daily maintenance process, we should spray more water mist around the orchid, orchids in different growth periods, the humidity requirements are also different.

Spring and summer are the time to accumulate nutrients and grow a large number of leaves, so at this time to fertilize orchids, it is recommended to use nitrogen fertilizers such as Huaduoduo No. 1, nitrogen can promote the growth of branches and leaves, and the potassium in it can also make orchids grow more dense roots and absorb more nutrients. Stomach Digesting Tablets should be the most common medicine at home, you can take out two Stomach Digesting Tablets, and then crush them into a clean plastic bottle, then add an appropriate amount of water, seal them and put them under the sun for two days, and then stir the solution and water in accordance with the ratio of 1:10, and directly water the orchid, you can add sufficient trace elements to the orchid, so that the orchid can grow better, and it is also acidic, and it can also adjust the pH of the soil.

The strength and weakness of the orchid mother seedling directly determine the strength of the new seedling.

When introducing orchids, it is best to use the front ridge seedlings, because the front ridge seedlings are germinated by the new strong seedlings and have congenital strong genes, so the seedlings will be more robust.

Some old and weak seedlings, although they can also germinate into seedlings, but the new seedlings are generally relatively thin, and it takes a certain amount of time to rejuvenate. It can be as short as two years or as long as three or four years.

Orchid seedlings are weak due to many reasons, from the situation you described and **, there may be the following reasons: first, the air flow on the sixth floor is strong, and the leaves often have transient water imbalance; Second, the roots are inherently weak and absorb limited nutrients; The third is the agglomeration of the bottom layer of the soil, which affects the aerobic respiration of the roots.

The preparation method of planting material is directly related to the strength and weakness of orchid seedlings.

Regarding how to prepare orchid planting materials, Haoshi Farmer has always emphasized three elements: loose and breathable, moisturizing and draining, and long-lasting fertilizer effect. The first two elements are known to many Lan friends and can be done.

In order to maintain the freshness of the environment, some orchids like to raise orchids with vegetarian planting materials, without adding humus and other planting materials with fertilizer effects.

As for slow budding, it has something to do with it.

What does the slow emergence of orchids have to do with the sprouts? The good farmer thinks that it is nothing more than these two points:

1. In the planting season, if it is an orchid planted in the autumn of the previous year, the budding will not be too slow after spring this year, and most of the buds that sprout are robust, and they can become strong grass that year.

Second, the potting soil or environmental humidity is not enough, the germination of orchid buds and the germination of flower buds are opposite, which means that they have opposite requirements for environmental humidity. The day after autumn is high and cool, and the air humidity is low, so it is suitable for orchid pregnant buds; In spring, the air humidity is suitable for budding, so wild orchids choose to sprout in spring and give birth to buds in autumn.

The first reason is that the soil in which orchids are grown is not fertile and the nutrient supply cannot keep up, the second reason is that the bottom of the soil is clumped, which limits the aerobic respiration of the orchid roots, and the third reason is that the soil or environment is not humid enough.

In summer, the climate is hot, and orchids enter a dormant period, and it is normal for them to grow slowly.

Light, although the orchid is shade-tolerant, when the long-term light is weak or insufficient, it will also make its growth slow.

Lack of water, insufficient watering or low humidity during the growing process will slow down the growth.

It may be that the roots are thin and provide limited nutrients, even if they have been watered and fertilized, but the leaves are still weak and dull.

The orchid grows weakly, and the problem lies in these two places, which are corrected in time to make the flower buds strong.

What kind of orchids do you raise? Different varieties of orchids have different breeding methods, and you go into my space to read the log, and mine is all about raising orchids.

If you want to raise orchids well, learn to use 3 tips to grow more vigorously.

First of all, the first reason is that the nutrient accumulation is too small, maybe the root system of the mother plant of your orchid itself is relatively small, and it will absorb less nutrients, then it may be because of the maintenance and management in the later stage, or the light is not enough, which will cause the new shoot to grow without enough nutrients, and it will grow less in the later stage, and it will be thinner.

Orchids under our normal maintenance can basically sprout, so after the sprout begins to spread its leaves, if the leaves of your sprout are very few, and short and thin, then what is the reason?

1. Nutrient accumulation is too small

First of all, the first reason is that the nutrient accumulation is too small, maybe the root system of the mother plant of your orchid itself is relatively small, and it will absorb less nutrients, then it may be because of the maintenance and management in the later stage, or the light is not enough, which will cause the new shoot to grow without enough nutrients, and it will grow less in the later stage, and it will be thinner.

Then we can regularly fertilize it so that it can be thick, we can use this potassium dihydrogen phosphate and urea, and then dilute it, and then water or spray it directly, which can promote its sprouts to grow better.

2. Excessive consumption

If your orchid mother plant has bloomed before, or has bloomed many times, the nutrients consumed are already very large, but after flowering, it has not been fertilized in time to make it rejuvenate, so selling a large front will cause the mother plant to weaken, and the new shoots it grows will be based on this situation, we should cut off the flower stalk in time after the orchid blooms, and then give it this rejuvenating fertilizer in time, so that it can regain strength as soon as possible.

3. Grow too many new shoots

Your orchid has grown too many new shoots, maybe your orchid itself is not very strong, but you often apply this germination fertilizer to the middle erection it, it may grow two or three or three or four new shoots at a time, and then the mother plant will be overloaded, and the new sprout will grow thin and weak if it is not nutritious enough.

Most of them are caused by insufficient water and fertilizer, too weak light, or hollow roots.

Probably because of the relationship between temperature and humidity.

1. What to do if the seedlings are weak.

1. Scientific soil distribution: When planting weak orchid seedlings, we must choose suitable planting materials. Because the root system of weak seedlings is very weak, it is necessary to plant with planting material with good permeability.

In addition, it is better to choose a planting material that contains orchid bacteria. Because they can assist orchid plants to absorb nutrients and help them grow better.

2. Proper shading: Orchids are more shade-loving, and their weak seedlings cannot withstand strong light. Therefore, when maintaining weak seedlings, it must be placed in a semi-shady place to avoid it receiving strong direct light.

3. Water and fertilizer control: When raising weak seedlings, avoid large water and fertilizer. Be sure to strictly control the frequency of watering and fertilization, and do not water unless the soil is dry. Do not fertilize unless the root system of the plant is back to growing. so as not to cause an additional burden on its root system.

4. Keep it ventilated: When maintaining it, it is necessary to keep it ventilated so as to provide it with fresh air. This will help increase its growth and make it grow stronger.

2. Can you use raw sawdust to raise?

Sawdust can be used to raise weak seedlings of orchids, but it is best not to use sawdust alone to raise orchids. Because it is very permeable, it is very suitable for the root growth of weak orchid seedlings. But if only sawdust is used to raise, its nutrient deficiency weakness will be highlighted.

Therefore, it is best to use it with some planting materials that are well mantilized and buried.
