Can potted orchids 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.

Jianlan should be fertilized

If you are raising Jianlan, now is a good time to grow buds and prepare for flowering, before the buds grow, when the buds are small, you should apply a little phosphorus and potassium fertilizer to promote the growth and development of the buds. In this way, the flowers can bloom smoothly, the flowers are of high quality, and it is easy to re-bloom after the flowers are gone. Jianlan can bloom at least twice a year, if the whole flowering period is not fertilized, it may lack fertilizer and bloom less or no flowering.

Fertilization can be applied when the local temperature is not very high

If the temperature in the area is not very high now, most of the time the temperature is below 30 degrees, the orchid has not yet dormant and is still in a state of growth, at this time you can apply a little fertilizer as appropriate to promote growth. In areas where the temperature is not high in summer, you can apply phosphorus, potassium fertilizer and compound fertilizer to fertilize orchids, and do not apply nitrogen fertilizer alone. Because most orchids have completed the initial differentiation of flower buds and have begun to enter the reproductive growth stage.

Phosphorus and potassium fertilizers help flower buds to further differentiate, and nitrogen fertilizer is not conducive to the growth of the whole plant.

Diseased orchids can be fertilized with a small amount of phosphorus and potassium fertilizer

If your orchid is sick, such as spots on the leaves, you can add a little phosphorus and potassium fertilizer when using fungicides (provided that the drug and phosphorus and potassium fertilizers do not react) to improve the resistance of the plant, improve the efficacy of the drug, and help to recover early. It is necessary to pay attention to the application of phosphorus and potassium fertilizer to sick orchids, the concentration should not be too high, the interval should not be too short, and it should be stopped after 2 or 3 times.

Fertilization is not applied when the temperature is high

If the temperature in the area is relatively high, most of the time the temperature remains above 30 degrees, and the orchid has begun to enter a semi-dormant or dormant state, do not fertilize. At this time, the growth rate of orchids is very slow, the demand for nutrients is relatively small, and fertilization is easy to produce fertilizer damage. Especially orchids like Chunlan and Molan, which will be dormant in summer, are more conducive to spending summer.

Fertilizer is not applied shortly after planting

Even if the temperature in the area is not high now, the orchid is still in the vigorous growth stage, if your orchid has not been planted for a long time, less than 3 months, it is recommended not to fertilize. Orchids that have not been planted for a long time, even if they have been potted and begin to grow, the root system is not lush, the resistance is poor, and fertilization is easy to produce fertilizer damage. Only when the root system has been relatively stable and the orchid has fully adapted to the existing environment, can fertilization get twice the result with half the effort.

Flower buds are already large and do not fertilize

Some flower friends' orchid buds may already be relatively large and are about to bloom, so don't fertilize and wait for the flowers to bloom. Fertilization will shorten the flowering period, affect the quality of flowering, and even cause fertilizer injury. One of my pots of orchid buds has just been unearthed, which can be fertilized, and the flower buds are a little bigger and start to rise quickly, so they should stop fertilizing in time.

Whether you can fertilize orchids in summer should be flexible. The plant is growing, so it needs nutrients and can be fertilized. If the plant has stopped growing and has little need for nutrients, then do not fertilize.

The higher the temperature, the greater the risk of fertilizing the orchid. In addition, summer is the high incidence period of orchid stem rot and soft rot, fertilization must avoid seedlings, only apply around the pot or foliar spray, do not let fertilizer water flow into the leaf center.

Do not apply fertilizer, because the temperature in summer is relatively high, and the potted orchid may go to sleep, and even if the fertilizer is increased, it will not be absorbed.

The temperature in summer is above 35 degrees most of the time, during this temperature, the growth of orchids is inhibited by high temperatures, and will not grow after growing slowly, after we fertilize orchids, fertilizers can not be effectively absorbed and utilized by orchids, resulting in waste, and will accumulate in the pot to make orchids appear fertilizer and fertilizer, so it is not recommended to fertilize orchids when the temperature is above 35 degrees in summer.

When I first started raising orchids, I would write down the date of every fertilization, watering, and spraying in a small book, my friends all know that the memory of a good farmer is not very good, so we must rely on a bad pen We often say that summer is not calculated from the beginning of summer, generally the summer solstice around June 20 is really considered summer, until August 21 is the summer season, the dates here are the solar calendar, because the solar calendar standard solar terms are more accurate These two months are the hottest seasons of the year, It's not that orchids are completely dormant and don't grow, it's just that in extreme heat, the orchid grows slowly, which makes it feel like it's paused, and I fertilized the orchids on July 2nd and August 2nd, with a one-month interval.

Can orchids be fertilized in summer?

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.

We all know that summer is the most vigorous period for the growth of orchid sprouts, so we must not be able to lack fertilization, as long as the temperature is right, we can properly top dressing it, but when we give orchid top dressing in summer, it has two fears that it is most afraid of these two kinds of fertilizer, if you apply these two fertilizers, it will cause orchids to burn seedlings, rotten buds, and even orchids die directly, so we give orchid top dressing, which two fertilizers it is most afraid of.

1.Make your own fertilizer and water.

The first fear is that I am afraid of this kind of homemade fertilizer water, because this kind of homemade fertilizer water, we dilute it after fermentation and rot, and water it in the potting soil, it will attract a lot of these pests and diseases, and it will eat the leaves of the orchid, which will not only affect the growth of the orchid.

It will also cause a large number of germs to invade the leaves of the orchid and this wound, causing your orchid to be diseased, so it is not recommended to use this homemade fertilizer like this.

2.Fast-acting compound fertilizer.

So what is the second most kind of orchid, is this kind of fast-acting compound fertilizer, the fertilizer effect of the fast-acting compound fertilizer is particularly fast, and the fertilizer effect is particularly poor.

We all know that orchids, it fertilizes more like clear, and prefers mild, thinner fertilizer, more fierce fertilizer, we usually can't use it, not to mention in the summer high temperature season, it is easy to burn seedlings and burn hate, it is particularly old this kind of fast-acting compound fertilizer.

3.Fertilizer selection.

So what fertilizer do we give to Orchid State, we must pay attention to the thinness of fertilizer, and must be mild, then we use fertilizer, you can use this family of organic nutrient solution, this nutrient solution can be sprayed leaves.

However, the dilution multiple is recommended for everyone, and it is best to turn it over again or sprinkle some slow-release fertilizer in the potting soil, which is very appropriate, so the two fertilizers that orchids are most afraid of in summer are these two, and you must not make a mistake.

Orchid can not be fertilized during the flowering period, 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.

1. Fertilizer cannot be applied

The growth of orchids needs sufficient nutrients, but when it blooms, it can not be fertilized, at this time, fertilization will cause its buds to wither, and the flowers will wither in advance, so that the flowering time of orchids will be greatly shortened, and in serious cases, it will also lead to fertilizer damage to plants.

2. The principle of fertilization

When fertilizing orchids, we must master the principle of thin fertilizer diligently, and must not apply raw fertilizer or thick fertilizer to it, for example, when its leaf buds grow, we can apply light fertilizer water several times to it, spring and autumn and about 20 days after it flowers, you can apply thin fertilizer every 2-3 weeks.

3. Reasonable watering

When the orchid is in bloom, it also needs to be watered reasonably, this time it is necessary to water less, it is best to observe that the soil is dry and then watered, and the amount of water should not be too much, when watering should be slowly watered along the edge of the pot, and the water must not be splashed on its flowers and leaves.

4. Light and temperature conditions

When flowering, it is also necessary to let it have a suitable light temperature, sunshine maintenance in a semi-shaded environment, so that it has an appropriate amount of scattered light irradiation, must not be exposed to strong light, but also need to do a good job of temperature control and ventilation measures, to avoid letting it in a stuffy environment, otherwise the plant is easy to grow poorly.

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.
