Now, the new shoots of orchids in your home are beginning to emerge, right? During this period, special attention should be paid to the maintenance, otherwise it will affect the growth and flowering of the whole year!
In general, orchids have two time periods of the year that are most suitable for new shoots, one is spring and the other is autumn. In most areas, new shoots will begin to germinate from the end of March every year, and then in the autumn from October to December, new shoots may sprout again when conditions are suitable.
But even if there are new shoots, the maintenance of the later stage is even less, and if you are not careful, the new shoots may become "black buds" or directly freeze the growth of the seedlings, which is a blood history that many flower lovers have experienced!
If you want the orchid to be more magnificent, more flowers to bloom, you will get more buds, and all of them will be raised one by one, today the flower lady will discuss with you about the maintenance of the orchid new shoots!
<h1>First, water</h1>
As the saying goes, "Raise a little bit of lan, water for three years"! Water is the basis for the survival of any plant and animal, but how to accurately grasp a "degree" of watering is not clear overnight, and it takes a certain amount of time and practice to slowly understand and figure it out.
In Feng Jingdi's "Twelve Wings of Lan Yi" at the end of the Ming Dynasty, the twelve major habits of orchids are recorded, including "joy and wetness; Raise Lanning dry without wetness; Like dry and afraid of dry", this "wet and wet", "dry and dry" must not be the same day, raising flowers is more important to pay attention to, too wet is wet, too dry is dry!
For orchids during budding, the potting soil environment should be maintained in a slightly moist state, if too wet, too much moisture, not only is not conducive to its growth, on the contrary, new shoots and roots are prone to anaerobic and rot black death, especially the current spring buds, if the maintenance of the problem will affect the growth and flowering of the entire pot for a whole year.
But also can not be afraid of water and afraid of hands and feet for a long time do not dare to water, potting soil is too dry will also affect its growth, the growth of new shoots is the need for sufficient water and fertilizer supply, otherwise the orchid buds will be because of the lack of water and fertilizer and dry and shrinkage!
In the past, in order to improve the humidity, we would often spray water to the leaves of the plant and around, but at this time watering or spraying water should be cautious, do not let the bud heart water, the resistance of the new shoots is poor, it is easier to be infected by the disease to cause black heart rot, so this stage can not spray water without spraying water, do not spray water like foliar spray or water, originally this month's rain is more, the air humidity is also greater than usual. If you find that there is water in the center of the leaf, you must suck it dry with a cotton swab in time!
<h1>Second, lighting</h1>
Although orchids are more yin, there are also "yin nourishment is good leaves, yang is more flowers" but it is not completely lightless, the growth of all things in the world is inseparable from light, especially for new shoots to make them grow stronger, better resistance, there must be more light!
But do not be exposed to the sun, now the sun at noon in May is more intense, easy to sunburn, to do a good job of shade, at noon as long as you accept some fragments of light or scattered light can be.
The light in the morning and after four or five o'clock in the afternoon is still relatively soft, it should be allowed to shine directly at this time, and this year's May is much cooler than in previous years, and it must be allowed to receive at least 2 hours of light every day to allow the orchid to grow strongly.
<h1>Third, if you want the new shoots to be stronger, you must first learn to fertilize</h1>
"A crop and a flower, all rely on fat to be the home", if you want the newborn orchid buds to grow strong, the supply of fertilizer is indispensable! Especially after the orchid leaf buds are unearthed, it has entered the peak period of vegetative growth, if the nutrients cannot keep up, it may lead to new shoots growing into weak seedlings, or even zombie seedlings, but also pay attention to thin fertilizer diligent application, scientific fertilization!
Generally speaking, after leaving the house in the spring, it is necessary to start applying "germination fertilizer" and "strong seedling fertilizer"!
The so-called germination fertilizer is mainly nitrogen fertilizer, which is applied twice at the end of March or before and after the Qingming Dynasty (the specific time mainly depends on the local temperature), once every 15-20 days.
The strong seedling fertilizer is a compound fertilizer with a balanced ratio of nitrogen, phosphorus and potassium, and the strong seedling fertilizer is a fertilizer that is applied for the longest time in a year, and it needs to be supplemented regularly in addition to the dormancy period.
However, it should be noted that when fertilizing, be careful to avoid splashing the fertilizer water on the leaf heart and the newly opened bud heart, otherwise it is easy to cause the leaf heart to rot.
<h1>Fourth, the protection of diseases and insect pests must be done well! </h1>
Ninety-nine eighty-one difficulties, the previous passes have come, it is not easy to survive the final level to raise the buds strong, but don't be infested by diseases and insects to eat. Especially pay attention to snails, slugs and stem rot is the most headache!
May and June is the most rampant activity of snails and slugs is the time, they like warm and not too hot time, the environment is humid and dark, the most afraid of direct sunlight, so often in the evening to start the activity, 10-11 o'clock in the evening is the peak of its dispatch, and then before the early morning and then sneak into the soil or hidden place, so whether it is artificial hunting or medicine must look at the timing of their activities, otherwise it is in vain.
Although they move slowly, they have a jagged tongue with dense teeth on it, and they use this tongue tooth to scrape the leaves, new shoots, leaf sheaths and new root systems of orchids, causing gaps or holes one by one, seriously endangering the growth of orchids and new shoots, and causing cross-infection of other germs.
Therefore, after pouring water, you must remember to pour out the water in the tray, and try not to use it without the chassis. As soon as a live snail or slug is found, it is immediately extinguished;
In addition, because they are active, they will pass from one pot to another, so they must first do a good job of isolation, and then carry out radical treatment, you can sprinkle some quicklime powder around the pot, or directly spray to kill, the general medication is: tetraformaldehyde granules, directly sprinkled on the surface of the pot soil, or spray the leaves and pot soil with spironylethanolamine salt dilution.
Stem rot is a major killer of orchids
In addition, stem rot is a major killer of orchids, new plants and old strains may be infected with disease, once infected, the onset of rapid disease.
The high incidence of stem rot is the orchid leaf spread period, as well as the high temperature and high humidity season, so it is necessary to start to do a good job of prevention work in the early stage and spray some fungicides regularly.
In addition, orchid potting must first resolutely eliminate the use of old growing mediums, especially underilized or diseased bacteria. For stem rot, the growing medium is its main medium of transmission, so whether new or old growing medium is used, the first thing is to disinfect and sterilize, you can spray fungicide in the sun, you can also use boiling water two or three times before use.
If infection with stem rot has been found, the diseased strain should first be isolated immediately to prevent other orchids from being infected;
Secondly, it is decisive to divide the plants, remove and destroy all the diseased parts, and replace them with new and clean growing medium, and destroy the old growing medium together with the diseased plant!
Finally, the drug is used to protect the uninfected plants, including the orchids in the adjacent pots, which can be easily soaked (20-30 minutes) diluted with carbendazim, zinc daisen or potassium permanganate.
Well, today I will share this first, pay attention to the flower girl, and learn more flower care tips!
