Do orchids need to be fertilized in summer?

Do not fertilize when it is hot.

There are two methods of fertilization for orchids, one is soil fertilization and the other is foliar fertilization. Orchid grows slowly, generally requires less fertilizer, more use of thin fertilizer diligent application method, in the spring and autumn of each year, when the orchid grows more vigorously, every 7 days to apply a rotten alum fertilizer water, of course, to see when the weather is relatively sunny, do not fertilize on rainy days; No fertilization is applied every year during high temperatures and severe cold; In the practice of orchid fertilization, we found that it is better to use organic fertilizer as the main fertilizer and inorganic fertilizer as the supplement.

The fading of the orchid may be due to too much sun. Generally, orchids do not turn yellow due to lack of fertilizer. Bad roots or exposure to the sun will turn yellow. If the orchid changes the soil every year, it generally does not need to be fertilized. Orchids simply cannot be fertilized during flowering and dormant in winter.

If you check that there are no bad roots or exposure to the sun, and you really want to fertilize, it is recommended to use it"Orchid King"Root application, proportions according to instructions, or foliar spray with 3 parts per 1000 potassium dihydrogen phosphate. These two kinds of flowers are sold in the market, and they are very cheap.

Proper fertilization, orchids should be lightly fertilized and applied frequently, I use a spray tank at home, and I use 1 1000 times the solution of chemical fertilizer.

You should pay attention to whether your orchid has rotten roots, and if there is, you should quickly change the soil, keep it properly dry, and also control the fertilizer.

In summer, you can't dry it, you can't fertilize it too much, and you should put it in a cool and ventilated place, otherwise you will get mold.

As we all know, the closed summer is the period when the new shoots of orchids grow most vigorously. Therefore, there must be no shortage of fertilization. As long as the temperature is right, we can properly top dressing the orchid.

However, when we top dressing orchids in summer, orchids have two fears, and they are most afraid of these two fertilizers. If these two fertilizers are applied, it will cause the orchid to burn seedlings, rot buds, and even die outright. So, when we top dressing orchids, which two fertilizers are they most afraid of?

1.The first fear of homemade fertilizer is this homemade fertilizer. Because if this homemade fertilizer is fermented and rotted, we will dilute it and pour it in the potting soil.

It will attract many of these pests and diseases, and eating the leaves of orchids will not only affect the growth of orchids. It will also cause the leaves of the orchid, and a large number of germs will invade this wound and cause your orchid to get sick. So homemade fertilizer like this is not recommended for everyone.

2.Fast-acting compound fertilizer: The second orchid is this fast-acting compound fertilizer. The fertilizer effect of fast-acting compound fertilizer is particularly fast, and the fertilizer effect is particularly poor.

We all know that orchids prefer to be clean when fertilizing, and prefer mild, relatively thin fertilizers, but bright digging is what we usually can't use, not to mention that it is easy to burn seedlings when it is high temperature in summer, and it is annoying. It is especially old with this fast-acting compound fertilizer. 3.

Fertilizer choice, so what kind of fertilizer should we use for Lanzhou? If we use fertilizer, be sure to pay attention to its thinness and mildness. Then, if you use fertilizer, you can use this company's special organic nutrient solution, and you can spray the leaves.

However, it is recommended that you double the dilution ratio, respect the kernel or sprinkle some slow-release fertilizer in the potting soil, which is very appropriate. Therefore, the two fertilizers that orchids are most afraid of in summer are these two, and they must not be applied wrongly.

Orchids can be fertilized in summer, but this time is not the best time to fertilize orchids, the most suitable for orchids is spring and autumn, during which they are in the rapid growth period, the growth process needs to have sufficient nutrients to maintain, and the amount of fertilizer in autumn is more than other times, because orchids need to store nutrients into the dormant period.

Can you fertilize orchids in summer is a problem that many friends who like orchids are more concerned about, you can fertilize orchids in summer, but this is not the best fertilization time, summer fertilization will not affect the growth of orchids, but the best fertilization time is in spring and autumn, because this time is the peak season for orchids, and nutrients are needed to support its growth.

1. Seedling stage

At this time, the orchid is in the seedling stage of spring, which is the best period for its growth, so timely fertilization for it can promote the growth of the orchid, and some compound fertilizer can be mainly applied, or some nutrient diluent, which can make the orchid at the seedling stage better absorb and speed up its growth rate.

2. Growth period

Summer and autumn are the peak season for orchid growth, so it should be applied an appropriate amount of nutrients, it should not be fertilized too much in summer, it is enough to apply phosphorus and potassium fertilizer once throughout the summer, and it is necessary to start fertilizing in October, because orchids need to grow and store enough nutrients to survive the winter.

3. Dormant period

Orchids in the dormant period can stop fertilizing, because at this time no matter how much fertilizer is applied can not make the orchid grow rapidly, but will have a counterproductive effect, which is not conducive to the normal growth of the plant.

1. Orchids cannot be fertilized during the flowering period.

2. At this time, fertilization will cause its flowers to wither in advance, to fertilize orchids to master the principle of thin fertilizer diligently, generally in its growth period to fertilize, about 20 days after flowering can also be fertilized, orchid flowering period should also be reasonable watering, light should not be too strong, the growth environment also requires warm ventilation.

If we use this orchid nutrient solution, we can use it according to the normal concentration, but if we use this water-soluble fertilizer, our concentration, it is best to double, if it is recommended to dilute 1000 times before, at this time it is recommended that everyone is best to dilute 2000 times to use.

I have shared with you before that the safest way to use fertilizer in summer is to bury a little magic fertilizer in the potting soil, which basically does not need to be used for a year, and there will be no damage to the roots.

Then some flower friends will reflect that they do not have this magic fertilizer at home, only some like this orchid nutrient solution, or some other, such as the flower Duoduo series of water-soluble fertilizers, then, how to apply it is safer, especially in this summer, I will share with you a very safe and simple way to use fertilizer.

1. The concentration selection must be appropriate

If we use this orchid nutrient solution, we can use it according to the normal concentration, but if we use this water-soluble fertilizer, our concentration, it is best to double, if it is recommended to dilute 1000 times before, at this time it is recommended that everyone is best to dilute 2000 times to use.

2. Stir well

Then when diluted with water, like this orchid nutrient solution, we can generally dissolve quickly, if it is water-soluble fertilizer, we must pay attention, because it is this granular type, we must completely stir evenly, to avoid it This particle is not completely dissolved, and it is easy to hurt the roots when poured in the potting soil.

3. Fertilizer method

At this time, we should not use fertilizer immediately, first water a small amount of water in the potting soil, and slowly water along the edge of the pot, at this time the watering can not be too much, we water a small amount and wait until the bottom of the pot, just have water flowing out, we can stop.

After a small amount of watering, we will fertilize it, so that at this time, you can directly water it thoroughly, why use this fertilization method, because, at the beginning of watering it with a small amount of water, wait until its root system, in a semi-saturated state, so fertilization, can also avoid bursting its root bark.

It is best for us to choose to fertilize every afternoon or evening, and then wait until the next morning, we will water it again to wash away the excess fertilizer in the potting soil, so that we can effectively avoid fertilizer damage and fertilize more safely.

This is a very safe fertilization method in summer, but we must pay attention to ensure that the maintenance environment is ventilated and breathable, so that this excess water can evaporate and avoid water accumulation.

In summer, the temperature should be controlled at about 20 degrees, not too high. Diffuse light is sufficient, and shade is needed when the light is too intense. Water well, but don't let water accumulate in the soil.

Because of the heat, fertilizer can be left out for the time being. To keep the soil slightly acidic, ferrous sulfate can be used for acidification. Also, pay attention to the prevention of pests and diseases.

Orchid growth has a characteristic, after flowering in spring, it will be in a stage of growing new shoots, and the new shoots will stop growing after they grow to a certain height, and the old buds will gradually stop growing for a period of time in the spring, which is to stop the growth of new shoots to differentiate flower buds, which is carried out in the hot summer. So what do we do in the hot summer? Don't lack water, keep humidity, keep ventilation, and regularly use some fertilizer to make it quickly dedifferentiate flower buds, give birth to flower buds, and then let its flower buds emerge before they can bloom in autumn and winter.

If you find that your orchid sprouts do not grow in summer, quickly change the fertilizer, the fertilizer is selected with phosphorus and potassium elements, the concentration is not high, the ratio of 1:1000 can be changed to the ratio of 1:1500, the interval is about 10 days, watering a little when watering, you can also go to it with water to dissolve, fine spray leaves, and continue until the end of summer.

But in summer, you must give the orchid shade, the orchid is most afraid of exposure to the sun, and the leaves will be sunburned when it is sunburned for half a day, so it must be put in a semi-shady environment, and you can see some scattered light, if there is a condition, you can put it under the tree, and this semi-shady environment is very suitable. Again, under the premise of ventilation, the three time periods of morning, noon and evening leaf spray to increase the moisture, if you are raising it outdoors, you can splash water on the ground to increase the air humidity is also very good.

The temperature is high in summer, it is hot, the potting soil dries very quickly, pay attention to the potting soil do not lack water, water it in the morning, or water it at night, because the planting materials we configure are very permeable, do not lack water, this is a very critical.

In fact, orchids are very easy to raise, especially in summer, as long as you ensure good ventilation, put it indoors or outdoors, don't lack water, regularly water it, water fertilizer, you can maintain a state for a long time, and the flower buds will be unearthed in autumn. After that, increase the proportion of phosphorus and potassium fertilizer, increase the concentration, and you can quickly raise the flower buds.

, what fertilizer is used for orchids 1, special fertilizer: there are special fertilizers for orchids on the market now. If you do not know how to prepare fertilizer, it is recommended to buy special fertilizer directly for orchid application.

The special fertilizer for orchids is specially designed for orchids, which is in line with the growth habits of orchids, and is suitable for fertilizing orchids. 2. Homemade fertilizer: If you don't want to buy special fertilizer, you can also make your own fertilizer.

Mash fruit skins, fish bones and other substances into a bottle, add some water, and let the water surface reach about three-quarters of the height of the bottle. Then screw the cap and put it in a warm place to ferment. After about 2-3 months, the fermentation is complete and they can be used as fertilizer.

When the event is over, it will be dead.
