After the beginning of spring, the temperature in many places is rising rapidly, especially in the southern region, at such a time, it is a critical period for the maintenance of orchidsBecause in.
In April and May, the orchid will enter the first period of growth. Careful care at this time will not only help the orchid survive the hot summer, but also help it grow and bloom vigorously. If this critical moment is overlooked, summer orchids can have all sorts of problems.
Therefore, the conservation of orchids in April is crucial, and there are three tasks that need to be completed in time to ensure that the orchids thrive and bloom on schedule.
The theme of this issue is to raise orchids in the month, and doing "4 things" in time is good for "growing seedlings and flowering". Let's look down.
Potted flowers, whether they grow well or not, has a lot to do with the soil they are planted, and the quality of the soil directly affects the absorption of fertilizer and water, so planting potted flowers must be used in the right soil, and the service life of the soil is 2-3 years a yearThe particularity of the root system of orchid plants determines that the service life of its planting material is shorter, and it is generally necessary to turn over the pot once in about 2 years and replace it with a new planting material.
The strength of the orchid is closely related to the quality of the planting material. High-quality planting material, the cultivation process is easy, new seedlings are erected, and flowers bloom. Poor planting materials will hinder the growth of orchids, and may even rot roots and be infested by pests and diseases.
We usually need to change the planting material for the orchid every two years or so, because after two years of use, the planting material will become barren or crumbling, which is not conducive to the growth of the root system. So, if your orchid hasn't changed its planting material for more than two years, then now is the best time to do it from south to north, generally in the south, and in the north, until March and April.
Between February and April, when the spring flowers are in full bloom, it is the best time to change the planting material and repot the orchids. At this time, the temperature is suitable, between 15 and 25, which provides a comfortable breeding ground for plants to grow, so that the orchids can be potted as soon as possible and resume growth as soon as possible.
In addition to changing the orchid planting material every two years, if your orchid is stunted, the leaves continue to turn yellow, or the dry tips are dry, whether it is more than two years old, you should consider repotting and changing the planting。Because orchids grow slowly, have yellowish leaves, or dry tips, this may be caused by poor root condition. Repotting and treating the root system, and replanting with high-quality planting material, the growth rate of the orchid will definitely improve. Otherwise, if there is a problem with the root system and is not treated in time, in summer, the orchid is very easy to die as a whole, and the phenomenon of dry tips of yellow leaves will become more and more intense.
What preparations do we need to make before turning the orchid into a pot?
Prepare the planting material
Before repotting orchids, we need to prepare planting materials, for many orchid farmers who have the right location, using the humus soil of the place of origin, the orchid can thrive. However, for those of us who live on the balcony, we often need to carefully select or configure our own planting materials.
First of all, we should make it clear that the soil in which orchids grow is that the most important thing is to have looseness, breathability, water retention, fertilizer retention and sufficient nutrients. These elements may seem simple, but in practice, we often need to use wisdom to reconcile. How to achieve the best ratio through the combination of different materials is a challenge that every orchid farmer needs to face.
Let's talk about the ratio of planting material. I found that the five-in-one coarse-grained planting material – perlite, fire soil, pine bark, phytolite, fairy earth, etc. – was a good choice. Together, these materials create a good environment for orchids.
My personal commonly used planting recipe is:Peat's peat soil 20 to 40 to 8 perlite 10 pine bark to 8 phytolite 10, snake wood or pine tendon 10, chestnut leaves 15. This ratio can ensure that the orchid has sufficient nutrients, and has the ability to retain water and fertilizer. Of course, the premise of sufficient nutrients is to ensure that the proportion of planting material is appropriate, which is also the part of orchid cultivation that we need to continue to explore and practice.
Different species of orchids may require different planting material ratios. thanFor example, I mainly use lotus petals and spring orchids, and I will adjust the ratio accordingly according to the characteristics of these two orchids. For those precious snake wood, if you feel that the ** is too high, we can also use loose ribs instead, and the effect is also quite good.
In general, orchid cultivation is not only a science, but also an art. It requires us to observe, experience and try with our hearts. I hope my sharing can be helpful to everyone, let us go further on the road of raising orchids together!
Of course, if it is convenient, you can mix the soil yourself, if it is not convenient, we can directly buy the special soil for orchid plants, which is more simple and convenient, suitable for novices.
It is best to soak the prepared plants in advance, and it is generally necessary to soak them in advance.
For example, phytolite, perlite, burnt earth, tree bark, coconut shell and charcoal must be carefully rinsed before use. You need to rinse with water several times until the water comes out. Materials such as phytolite, fire soil, bark and coconut shells require prolonged immersion in water. In general, you may need to change the water 2-3 times (Some carbendazim can be added to the water）。This rinsing and soaking process is designed to remove powder and possible eggs from the planting material. In addition, it also helps to anneal the hard planting material, allowing them to absorb enough water so that the orchid can recover smoothly after potting and reduce the occurrence of pests and diseases.
Generally, the planting material is best to achieve a "moist but not wet" state before potting. It is best to form a ball with your hand, and it is best to spread it out by loosening it.
Control water in advance
Before repotting orchids, we must control the water in advance, generally need to control the water for 7-10 days, according to the air permeability of the planting material and the humidity of the air to decide, it is generally necessary to let the planting material reach a loose state, so that it is easy to depot, do not hurt the roots.
Prepare your pots
Orchids generally after about 2 years of growth, will find a lot of new plants, seedlings will be more, if your orchid is also such a strong seedling, be sure to prepare the pot in advance before turning the pot.
Either a larger pot than the original size, you can also prepare a few small pots to divide the orchid.
If the pot is used in the original old pot, it is best to expose it to the sun in advance, or rinse and disinfect it with boiling water.
Dry the roots
Orchid depotting depends on rotating and patting around the pot, so that the orchid and orchid soil will naturally come out of the pot. It is not possible to directly drag or drag the orchid plant to be unearthed. After the orchid is depotted, gently dispose of the orchid soil on the orchid root, and it does not have to be treated very cleanly.
Then check the root system to see if the root system is robust, if there are empty roots, rotten roots and some not very robust roots, you need to cut them off in advance, and then dry the roots, until the roots are slightly softThen soak it with rooting powder and carbendazim for 15-20 minutes, and then pot.
Planting
When we plant orchids, we first select a few mussel shells or thin tiles, with their convex sides facing up, staggered and overlapped with each other, tightly covering the stomata at the bottom of the orchid pot. Subsequently, we cover it with a layer of coarse mud grains or charcoal blocks, which occupy about a quarter of the depth of the pot. Next, we place the carefully treated orchid on coarse mud grains or charcoal cubes and comb its roots to allow them to stretch naturally.
Then, we start filling the perimeter with orchid mud or humus-rich soil, gradually adding to the base of the orchid plant. In the process of continuing to fill, we gently suspend the orchid plant with our hands to stretch its root system, which helps the orchid plant to grow and survive better. When the culture soil is close to the edge of the pot 2 cm, we gently poke the orchid pot a few times to make the orchid root more closely bound to the potting soil, and also keep the surface of the potting soil flat.
Finally, we spread a layer of white pebbles on the surface of the potting soil, or plant some emerald cloud grass. This decoration is not only aesthetically pleasing, but also keeps the surface of the potting soil moist and prevents the soil from being washed away when watering.
When planting orchids, it is important that we add some base fertilizer to the orchid to promote its growth. If you don't turn the pot today,Be sure to give it top dressing in time, as long as the temperature is not lower than 15 degrees, you can give the right amount of fertilizer, especially after the onset of spring.
When the weather warms up, the orchids have begun to take on a new appearance, and in this time of life, fertilization is undoubtedly a top priority. If this link is neglected, not only will the growth of new shoots be hindered, but even the blooming of orchids in winter and spring will be affected. When orchids bloom in winter and spring, they consume a lot of nutrients, and if they are not replenished in time, the new bud points will be sparse and the growth rate will be slow. What's more, most orchids begin to differentiate their flower buds in the month, a process that also requires sufficient nutrients to support. Therefore, fertilization in early spring is particularly important.
During the growing season of orchids, how to safely use chemical fertilizers is a big problem. Through practice, it has been found that the way of burying is the safest. When operating, you need to dig a shallow gully at the edge of the pot (as far away from the root as possible), and sprinkle the fertilizer evenly in the ditch, and the amount is referred to the instructions.
Then lightly cover with the planting material, making sure that the fertilizer solution does not come into contact with the langen quickly. In this way, the root has enough time to slowly adapt to the nourishment of the fertilizer, thus reducing the chance of fertilizer damage. Generally speaking, this method is recommended for both ternary fertilizer and slow-release fertilizer. In addition, because evaporation is avoided, the effect of fertilizer can be more fully exerted, and the utilization rate is greatly improved.
In addition to those precious and rare species, many common orchids are not difficult to develop new seedlings as long as they are properly maintained. It may only take a year or two of careful care for them to allow you to witness a multiplication of seedlings. However, when the pot appears small and the number of orchid seedlings is excessive, there will be a lot of pressure on the growth of the orchid. At this time, it is particularly important to reap orchid seedlings or replace them with larger pots in time. Spring is the best time for orchids to be seeded (generally from February to May, depending on the local temperature). Please be sure to grasp this critical moment and give the orchid the most intimate care.
If the orchid happens to need to be repotted, when the pot is turned, you can do a good job of dividing the plants by the way, if it is not the time to turn the pot, it is recommended that the orchid with more seedlings is also divided in time, so as not to affect its growth.
Lighting
Orchids like light, but do not like strong light, the light in early spring is not very strong, we can let it accept full sun maintenance, between 20-25 degrees, the light is too strong to need shade, can not be strong direct light, can not lack of light, otherwise it will affect the growth of orchids.
The spring and winter suns, like a gentle breeze, are soft and warm, and orchids can enjoy the gift of full sunshineHowever, at midday (depending on the temperature), it is still necessary to provide a little shade to avoid excessive heat
In addition, the newly planted orchids cannot withstand the baptism of sunlight during the potting period, and need to be placed in a ventilated and shady place. After about a month, when the orchid has adapted to its new environment, it can enjoy the warmth of the sun. For those who are new to orchids, if it is difficult to grasp the scale of the sun, it is the safest choice to find a place where you can bask in astigmatism。In this way, the growth of the orchid will be guaranteed, and you will be able to enjoy its beauty with peace of mind.
Watering
Orchids like a higher humidity air environment, generally higher than 70%, they will have green branches and leaves, but to ensure good ventilation, but orchids are very afraid of waterlogging, mainly because the root system is fleshy roots, waterlogging, poor air permeability of planting materials, it may make orchids appear "stuffy roots, rotten roots" phenomenon.
Therefore, watering orchids should not be too frequent, but there will be no shortage of waterWe need to carefully observe the leaves and tips of the orchid before watering, if the leaves are straight and straight, there is no curling, and the leaf tips are not scorched or dry, this indicates that the orchid is not short of water, and there is no need to water at this time.
You can also look at the planting material, the surface planting material of the orchid pot has dried thoroughly, and when the surface planting material is about 5cm, it is still dry, indicating that the planting material has insufficient water and should be watered.
To increase humidity, it is best to spray more water mist on its leaves and the surrounding air, or use a humidifier, especially in northern regions.
In the case of good ventilation, it is also possible to spray with large water. In particular, orchids raised outdoors are generally sprayed with large amounts of water. If the temperature is right in spring, you can increase the frequency of watering moderately.
Prevention of pests and diseases
Spring is the high incidence of pests and diseases, we must prevent it in time, to know that raising orchids, for pests and diseases, prevention is always greater than **,Maintaining good ventilation is key, and it's a good idea to incorporate some medication for prophylaxis.
Prevention can be used Lan Lingwang microbial agent is a special nutrient solution fertilizer for orchids, the fertilizer is natural, safe, 100% organic, increase roots and strengthen seedlings, promote flowering, indoor comprehensive nutrients supplement all orchid general-purpose type, etc. Its main components are Bacillus subtilis, Bacillus licheniformis, Trichoderma harzianum, lactic acid bacteria, nitrogen-fixing bacteria, actinomycetes and various secretory sporases, which promote the balance of total nutrition and regulate growth. **10,000 Fans Incentive PlanHere are eight common pests and diseases and how to control them to bring orchids back to life.
Anthrax and black spot, two fungal leaf diseases, make orchid leaves mottled and dry. But don't be afraid, use a good Qingxian spray for prevention and control, use it once every 5-7 days, use it three times in a row, remember to cut off the spotted leaves before using the medicine to reduce the source of bacteria.
Stem base rot and root rot, which are root diseases that focus on prevention. During daily maintenance, water Fumeng once a month, cut off the rotten part in time after the onset of the disease, soak it with Fumeng for 30 minutes, dry it and replant it.
Thrips and scale insects, stinging and sucking mouthparts pests are a headache. Use Ruili to prevent and control, press the vacuum bottle four times with 500 ml of water, shake evenly and spray on the foliar surface, water the remaining liquid medicine, use once in 5-7 days, and use it three times in a row.
Remember to cut off severely damaged leaves before applying medicine to reduce the source of insects. Red spiders, an "old friend", are everywhere. Use Beiqingjing spray for control, spray once every five days, spray three times in a row, and pay attention to the back of the leaf must be sprayed.
The scorching point problem is not actually a disease, but is caused by too dry air, too low humidity, and poor ventilation. For example, in the north, orchids are raised in the spring and autumn, as well as in the heated winter months. The situation is much better if humidification equipment is used and ventilation is strengthened. I hope these prevention and control methods can help orchid friends and make orchids grow healthy and strong.
The moon is a good time to raise orchids, and this is the time when spring is full of joy and everything is recovering. In order for orchids to thrive and bloom to the fullest, we need to hurry up and do 4 things well.
Even for the Jianlan that blooms in summer and autumn, the maintenance of these two months is crucial. Let's learn these 4 things together to lay a solid foundation for orchid growth and flowering. If you think this flower raising knowledge is helpful to you, please like and follow, and I will continue to share more flower raising experience.
