What should I do if the concentration of foliar fertilizer in orchids is too high?

Prepare a pot of water and sprinkle it evenly on the surface of the orchid leaves, through this method to dilute the high concentration of fertilizer.

Change some soil, and when you change that soil, it won't be as concentrated.

Raising orchids and spraying foliar fertilizers, have you paid attention to these concentrations?

1. Enhance lighting.

If the orchid does not see light for a long time, it will grow white, which will make the leaves longer. It needs to be placed in the sun, but it should be properly shaded at noon to avoid exposure to the sun and dehydration. If there is enough light, the leaves will not continue to grow.

Second, reduce the surplus fertilization of the Qiao family.

Another cause of overgrowth is too much nitrogen fertilizer. It is not advisable to fertilize for a short time, remove the plants from the pot and rinse them with water. Dilute the fertilizer to avoid further overgrowth. You can also change some new soil to slow down its growth.

3. Moderate pruning and filial piety.

Because the leaves of orchids are too long, they are prone to lodging and do not look aesthetically pleasing, so they need to be pruned properly. Cut the long leaves short and prune the roots. Remove the plant from the pot, wash off part of the soil, cut off the excess roots, and replant.

Cutting the roots will prevent it from absorbing water and nutrients, slowing down its growth.

Fourth, manual folding.

If you don't want to cut off the leaves that are too long and are worried about breaking them, you can fold them manually. Make a triangular bracket with steel wire and use it to fix the leaves that are too long to avoid the orchid lodging. After a while, let it go in time and let it grow more naturally.

Don't tie it up with a rope, it won't look good and it's not good for growth.

Foliar fertilizers commonly used in orchids include Instant Liquid, Huabao, Phytoquan Comprehensive Mineral Jiansheng, Gaole, Huaduoduo, Gaohuamai, Aishi Brand, Aiduo Harvest, Spray Shibao and other fertilizers.

When spraying foliar fertilizer, make sure that the front and back sides of the orchid leaves can be sprayed, especially the back side of the leaves, and its pores have a stronger ability to absorb the fertilizer than the front.

1. What are the foliar fertilizers for orchids?

1. Quick-growing liquid fertilizer: the fertilizer can adjust the pH of the substrate, and after spraying, it can also make the bulb of the orchid become larger, the leaves become thicker, and the line art becomes more obvious; When using, it can be diluted to 1000 times the liquid before spraying.

2. Huabao (No. 1-5): The fertilizer is produced in the United States, and it can be diluted to 1000-2000 times when used, and then sprayed.

3. Phyto-complete comprehensive mineral health and biotics: The fertilizer is produced in Japan, and it can be diluted to 3000-5000 times when used, and then sprayed.

4. Gaole: The fertilizer is produced in the United States, and it can be diluted to 1000-1500 times when used, and then sprayed.

5. Huaduoduo: The fertilizer is produced in the United States, and it can be diluted to 1000-1500 times when used, and then sprayed.

6. High-yield buying: The fertilizer is produced in Fujian, China, and it can be diluted to 400-500 times when used, and then sprayed.

7. Aishi brand: The fertilizer is a high-nitrogen, high-potassium foliar fertilizer, which can be diluted to 500-1000 times when used, and then sprayed.

8. Aiduo Harvest: The fertilizer is produced in Japan, and it can be diluted to 6000 times when used, and then sprayed.

9. Spraying Shibao: The fertilizer is produced in Guangxi, China, and it can be diluted to 10,000 times when used, and then sprayed.

Second, the advantages of foliar fertilizer

1. The use of foliar fertilizer is extra-root fertilization, which has the advantages of being fast, safe and less limited than root fertilization.

2. After spraying foliar fertilizer, the fertilizer solution will be absorbed by the orchid plant soon, and it will be absorbed faster than the root fertilization.

3. Root fertilization of orchids in a special environment may cause fertilizer damage, but spraying foliar fertilizer will basically not produce fertilizer damage, so foliar fertilizer is a relatively safe fertilizer.

3. Precautions for spraying foliar fertilizer on orchids

1. Spraying should be done in rainy days, cold and hot weather is not sprayed, if you want to spray in summer, the spraying time should be selected after the sun sets.

2. When spraying, it is necessary to ensure that the front and back of the orchid leaves can be sprayed with fertilizer, especially the reverse side of the leaves, and its pores have a stronger absorption capacity for fertilizer.

3. Foliar fertilizer should not be used frequently, otherwise the orchid plant will be dependent, and long-term use will affect the fertilizer absorption ability of the root system.

Orchids are not afraid of overwatering, and there is actually a wrong logic about how to overwater the orchid. Orchids are afraid of water accumulation in the planting material, which is not transparent, so even if they do not water much, it will also cause rotten roots.

Some orchid orchards use pure hard planting materials, which is for the convenience of water and fertilizer management. The orchids planted with this material are not afraid of water, and there will be no water accumulation in the pot after watering, but the planting material will be moistened again. Therefore, if the planting material is right, no matter how much water you pour, you are not afraid.

The reason why the subject raised this question should be that the water accumulation caused the Langan problem, which should be the planting material is not enough to drain water. If you water too much in this way, the first problem is that the leaves will have yellow spots, and sometimes they will be mistaken for disease spots and only use medicine, which will not cure the source of the spots.

Since the subject himself has found that it is caused by excessive watering, it is easy to do, pour the pot and change the planting material, and add more hard planting material with good drainage. Then pay attention to the ventilation of the orchid environment, be sure to ventilate! The reason why wild orchids do not have problems during the rainy season is that the soil is loose and breathable and drains, and on the other hand, the environment is naturally ventilated.

If it is found early, Langan has not yet begun to rot, so treatment will be fine. If the roots are rotten, they must be repaired, dried and then repotted. Rooting, root raising, root protection, choose Woye Root Lefu rooting agent.

Orchids are overwatered.

Causes of overwatering:

Causes of overwatering orchidsIn addition to frequent watering, the planting material is not loose and breathable, which can also lead to water accumulation in the orchid pot, which can lead to overwatering.

Dangers of overwatering:

Orchid leaves will wilt if they are overwatered, become soft and yellow, and the whole plant will die severely.

Re-entry Initiation Method:

If the orchid is overwatered, you can drain the stagnant water first, then place the potted plant in a well-ventilated environment and wait for the water to evaporate completely. You can also turn over the soil on the inner surface of the pot, but you can not wash the strip to hurt its roots.

Orchids are drenched in rain.

Orchids are most afraid of half rain in summer, which will have a certain impact on the growth of orchid roots. If it is the rain that can wet the orchid pot, then it will not be okay, the plant material will cool with the rain.

Orchid watering points.

How much water to water at once:

Orchids should be watered thoroughly every time to allow the plant's roots to absorb water evenly. If you don't water it properly for a long time, the roots at the bottom will not absorb water for a long time, the growth will not be good, and the plant will dry up easily.

Watering frequency: When watering the orchid, it is best to keep the potting soil dry, watering less times during the flowering period, and not too much water. In summer, it needs to be lightly watered in the morning and evening, and the number of watering can be increased appropriately in autumn.

What water grows well:

Orchids can be watered with rainwater, river water, pond water, etc. All of these waters are rich in minerals, which are conducive to its growth and can promote its vigorous growth. Tap water is also fine, but tap water should be left to dry in a ventilated and dark place for two days before use.
