Orchid fertilizing and watering techniques: did you get these planting steps right?
Recently quite a few flower lovers have consulted the Huinong website's back office about orchid cultivation. The editor summed things up and found that everyone's questions were pretty much the same, so I'm sharing them below mainly to exchange ideas with everyone.
How do you grow orchids? Among China's traditional famous flowers, orchids mainly refer to Cymbidium ensifolium, Cymbidium sinense, Cymbidium kanran, Cymbidium goeringii and Cymbidium faberi. Elegant and delicate as orchids are, they are not all that easy to grow. Today we will mainly look at the issues to watch out for when growing orchids.
1. Watering issues
Generally speaking, watering orchids involves some know-how. Water should be poured slowly around the edge of the pot; you must not pour it on the leaves, and even more so not on the leaf crown of the orchid, otherwise water will accumulate in the orchid's pseudobulbs and roots, causing disease infection and the appearance of root rot and stem rot. This is especially serious when the water quality is not very clean.
Also, try to water around ten o'clock in the morning. After watering, the water will evaporate quickly, which avoids standing water and reduces the occurrence of disease.
2. Improper fertilizing
Fertilizing orchids involves knowledge. Using strong fertilizer or chemical fertilizer often causes root discomfort, lowers the orchid's resistance, and makes it highly susceptible to disease. For orchids, try to use organic fertilizer, decomposed farmyard manure, liquid fertilizer and so on. But these fertilizers must be thoroughly decomposed to avoid bringing in pathogens after use. Only reasonable fertilizing will reduce disease and make orchids more robust.
3. Ventilation issues
Orchids like ventilation and air flow, and the growing medium should be loose so that the orchid roots can come into contact with air as much as possible; only then will the orchid's resistance improve. Especially in the hot, stuffy summer season, when orchids are prone to disease, ventilation and air flow are even more important: they can lower the temperature and also reduce the probability of the orchid getting sick.
4. Growing medium issues
In orchid care, the growing medium is crucial. You could say that if you choose the right medium, growing orchids becomes relatively simple. Besides being loose and breathable, the medium needs particular attention to sterilization and disinfection. Pine needles and chopped bark in particular may carry pathogens or insect eggs, and even after decomposition they may not be cleaned out thoroughly, so the medium must be disinfected before potting orchids.
For disinfection you can steam or boil it, soak it in potassium permanganate, or spread it out on a concrete surface in the sun, and so on. Once the medium is properly treated, disease will naturally decrease.
Overall, growing orchids still requires flower farmers to be a bit more careful in daily life and to learn more professional orchid-growing experience, or to come to the Huinong website and exchange ideas with other flower farmer friends!
An introduction to orchid care methods (fertilizing and watering)
Many flower lovers like growing orchids, but they just can't grow them well. Today we will focus on the issues of fertilizing and watering orchids, for everyone's reference and learning.
June to July is the time of year when air humidity is relatively high, and watering needs attention in 4 points:
1. Do not water after rain, and do not spray water on orchid leaves when air humidity is high.
2. This stage is the key period for orchids to grow roots and leaves, so you must keep dryness and moisture in balance. Keeping dryness and moisture in balance means you must water thoroughly, and after that, try to water again only when the medium's moisture is below 30 percent (even 20 percent is fine). Only this way will the root system develop well and be encouraged to grow downward.
3. Keeping the medium at too wet a level for a long time leaves the orchid's roots and leaves in a saturated state. If you then water or spray again, the orchid's roots and leaves cannot absorb it, which very easily leads to new shoots rotting, soft rot, stem rot and various diseases. Only by keeping dryness and moisture in balance can orchids grow healthily.
4. For watering and spraying, choose the evening or early morning; do not do it during the high-temperature, sunny time period.
The overall principles of watering are:Water when dry, stop when wet, and lean slightly toward dry.
For fertilizing, you only need to remember 2 principles:First, apply thin fertilizer frequently; second, whether applying root fertilizer or foliar fertilizer, try to do it in the evening.During the growing season, water once every half month with decomposed bean cake water or water from horse-hoof bean paste residue. Adding an appropriate amount of monopotassium phosphate gives even better results. Do not fertilize in the heat of summer. When the temperature is too high (above 32°C), besides daily watering, spray water several more times. Slightly acidic water is preferable. Frequently spraying and washing the leaf surface with clean water not only improves the growing environment of the potted orchid, but also keeps the leaves clean and reduces the chance of pest and disease infection.
In addition, orchids need continuous pruning during cultivation. When old leaves turn yellow and dry, they should be cut off promptly to improve ventilation, and leaves whose tips have dried out should also be cut off. Leaves damaged by pests or disease in particular need to be removed promptly to avoid transmission. When cutting off leaves with viral disease, do not use the same scissors to then cut healthy leaves, to prevent virus transmission. If you use the same pair of scissors, they must be disinfected.
Summary: The above is an introduction to knowledge about watering and fertilizing orchids. We hope it is helpful to the many orchid growers.

How do you grow orchids? The ancients left us this experience: "three parts planting, seven parts care" in growing orchids. In China, orchids are something pure and elegant. They have been praised by many ancient poets. Many people also compare themselves to orchids for purity and elegance. So what about orchids? Many friends may not be too clear about it. Please keep reading for orchid cultivation methods:
[Orchid planting methods]
1. Soil:Orchids are not strict about soil. It is best to choose a mix of loose, fertile, well-drained sandy soil and weed soil ash, which is more conducive to orchid growth.
2. Light:Since orchids are short-day plants, they do not need too long a daily light period; indoor diffused light is enough.
3. Temperature:Since orchids are cold-tolerant, temperature control can be fairly rough. The most suitable temperature for growth and flowering is between 15°C and 25°C.
4. Fertilizing:Orchids like fertilizer; only with ample fertility can orchids grow faster, and it will also promote the flowering and fruiting of February orchids. Fertilize 4 times a year. Regular fertilizing will also make the flower colors more brilliant and the fruits fuller.
5. Watering:When watering orchids, never just fill tap water and pour it on. It is best to use rainwater and spring water, so that more nutrients can be absorbed. When watering, pour from the edge of the pot; do not pour directly down from the middle of the orchid. In winter, however, keeping it 20 percent moist is enough.
6. Pests and diseases:Common pests in February orchid cultivation include aphids, cabbage caterpillars, snails, leaf miners and so on. If pests are found, promptly carry out chemical control.
7. Climate changes:Orchids are not very delicate and can be rained on, but they are very afraid of plum rain and heavy rain, otherwise it will cause heart rot and leaf rot. During the plum rain season, a small amount of plant ash can be sprinkled appropriately.
8. Pruning:To maintain a good ornamental effect for February orchids, you must control them so they do not set seed. Generally, during the seed-setting period, use a lawn mower to trim them to a height of 10 ~ 15 cm.
9. Flower removal:For orchids that grow poorly, a large number of flowers should be removed, so as to ensure normal growth. For varieties that grow well, some flower buds can also be appropriately removed; this way the flowers can bloom longer, more new leaves can sprout, and old leaves are less likely to wither and die.
[Notes on orchid cultivation]
First, watering:Do not water every day, otherwise it will cause severe root rot. Do not use tap water, as it contains chlorine.
Second, temperature:Many people generally place Phalaenopsis in the living room and other places for appreciation. Although the daytime temperature in these places is sufficient, the nighttime temperature is a bit on the low side, and the humidity is not enough either, so very close attention is needed.
Third, fertilizing:Many people think that once they fertilize, the plant will grow very fast. This is a very wrong approach. Phalaenopsis should be given thin fertilizer, in small amounts and many times; do not "over-nourish" it, otherwise the result will be the opposite of what you want.
Fourth, potting:Use a large pot. A large pot can give Phalaenopsis a loose environment with ample material, and the sphagnum is not easy to dry out. Phalaenopsis likes air flow, and when air flows well it grows very well.
Conclusion:The orchid is one of the four gentlemen, and the orchid represents a kind of temperament and elegance in people. It is also a must-choose plant for indoors. Orchids have become the most distinctive element in the field of landscape greening. For more about growing plants, please keep following Aiyouwo Information.
