What causes orchid black tip? What is the difference between black tip and scorched tip of orchid

It should be sick, you can use thousands of seasons to be leisurely, its effect is relatively good, and it will not cause harm to people and the environment.

This is a fungal disease, you can try it with thousands of seasons of good leisure, I was the problem before, and then cured.

The main difference between the black tip and the focal tip of orchids is that they are caused by different causes.

The appearance of black tips in orchids is usually caused by high humidity or poor ventilation, while the appearance of scorched tips in orchids is usually caused by insufficient humidity, lack of water, and excessive sunlight. If the orchid is scorched, consider shading, humidification, and water first; If the orchid is a black tip, it is necessary to consider moisture drainage, ventilation, and increase light, which is conducive to the growth of the orchid.

There are certain skills in orchid maintenance, and it is necessary to move it to a warm place in winter to avoid frostbite from low temperatures. Wait until the temperature is completely stable before moving it outside. At the same time, it is necessary to let the orchids receive astigmatism, and it should be properly shaded when the sun is heavy at noon.

In winter, the daylight is relatively short and the sun is not strong, so it can be allowed to receive all-day sunshine. If you water it, you should water it once a day when the temperature is high, and once every two days when the temperature is low.

Prevention and control of scorching tips:

First, the water of the orchid pot needs to be kept moist. Summer and autumn water should be slightly more, winter and spring can be less, usually pay attention to keep the potting soil moist.

The second is to try not to expose the orchid plant to the sun, and it is better to ventilate it with frequent breezes.

Third, the fertilization should not be too thick, and it should be applied thinly and diligently. You can also spray anthers in a timely manner to prevent diseases, and you can't wait for pests and diseases to be cured.

Orchids appear black leaf tips, optimistic about these 4 points, quickly find the cause.

The reasons for the black tip of orchid leaves include natural factors, improper maintenance and management, the aging of orchid leaves, dry air, and roots touching the bottom of the pot.

1. Natural factors

Orchids prefer humid climates, and too much dry air will cause orchid leaves to be scorched, which is more common in the north where the air humidity is low, especially in winter. In this case, we can increase the humidity of the air by spraying or using humidification equipment to keep the orchid in a suitable growing environment.

2. Improper maintenance management

Improper management in the daily maintenance process of orchids can also lead to blackening of orchid leaf tips, which are commonly caused by too strong light, insufficient light, too much watering, too little watering, excessive fertilization, and too concentrated spraying, all of which are artificially controllable.

3. Orchid leaves are old

Orchid leaves also have a certain lifespan, generally at 45 years. Lifelong age tends to start from the leaves of the feet and wither from the tip of the leaves from top to bottom, while the other orchid seedlings are normal. At this time, the leaves can be cut off as soon as possible to retain the nutrients of the reed head for other orchid plants; Or when there are still 12 orchid leaves left in the old reed, they will be divided in time to cultivate new shoots.

4. Air drying

The most suitable air relative humidity for orchids is 70%, at least not lower than 55%. Dry air or strong winds can cause anxiety. In this regard, you can use a humidifier to spray at intervals, or store water around the pot, lay up the damp sand, etc., to increase the humidity.

5. The root touches the pelvic floor

If the orchid pot has not changed the soil for many years, the root root is too vigorous, the root tip touches the pot wall, and the high temperature burning will also cause scorching tips. The black spots caused by this condition stay at the tip of the leaf and do not spread into the leaf. In this case, you should temporarily avoid scorching sun exposure and high temperature scorching, and divide the potting in time when the autumn temperature is suitable for changing pots.

First of all, the first reason is that the planting material is not breathable, the planting material is not breathable, and the root system has a stuffy root, and the crystal head will be black. The second reason is that some flower friends may not do a good job of cooling when raising orchids in summer, and then fertilize orchids when they are relatively hot, or when they fertilize orchids, the concentration of silver and silver is too high.

The orchids we planted in the spring have basically grown a lot of new roots at this auspicious feast, that is, they have grown a lot of crystal heads, so some flower friends may find that your orchid is rich in water, so why the crystal head is black, in fact, there are two main reasons.

1.Breathable

First of all, the first reason is that the planting material is not breathable, the planting material is not breathable, and the root system has a stuffy root, and the crystal head will be black.

2.Fertilization

The second reason is that some flower friends may not do a good job of cooling treatment when raising orchids in summer, and then fertilize orchids when they are relatively hot, or when they fertilize orchids, this concentration is too high.

If the concentration of fertilizer is too high, then it is easy to produce fertilizer damage, hurt its crystal head, and then the crystal head will be black, so what should we do in this situation.

3.Here's how to fix it

At this time, we must depotting after depotting, replace some new planting materials, this new planting material, must be enough to say that the granular planting material is appropriately more, such as pine bark and other more nutritious planting materials, we are appropriate to be a little less, so as to enhance the permeability of the planting material, water filtration.

Then the loose air permeability of the planting material has improved, and the planting material is not so fertile, we can do it, wait until your crystal head slowly turns white, we will properly fertilize it, and the fertilization must be accompanied by thin fertilizer, can not be agricultural fertilizer, in order to avoid the blackening of the orchid crystal head, to do a good job in the two aspects of planting material and fertilization.
