Urgent! Urgent! Urgent! Friends who raise orchids pay attention

Ask me, okay, I raised more than 500 pots, his method is not practical for you Judging from the situation you said, it may be a scale insect that can be killed with insecticidal No. 4, pine needles can raise orchids, but it is easy to rot roots, it is best to use humus soil and sand, and you can't irrigate head-on when watering, orchids don't like water very much, you can water it once every half a month, and you can water it once a month in winter.

Detail 1: Watering. Orchids prefer moist environments, so be sure to hydrate them well. However, avoid stagnant water, if you water too much, it is easy to rot its root system, so just keep the soil slightly moist.

Detail 2: Ventilation. The growth temperature of orchids is 18 28, and more than 35 is not conducive to the growth of orchids. Therefore, it must be ventilated, so that the orchid can be cooled down through some transpiration, so that the orchid grows more and more vigorous.

Detail 3: Humidity. Low air humidity is not conducive to the growth of orchids, so be sure to enhance its humidity, you can often spray some water around, or put a pot of water next to the orchid, which can not only enhance the air humidity, but also achieve the effect of cooling.

Detail 4: Control of pests and diseases. Daily maintenance of orchids must pay attention to hygiene. You can use edible vinegar and water to stir evenly in a ratio of 1:10 and spray it directly on the leaves, which can not only make the leaves green and shiny, but also control pests.

Orchids can be maintained by drainage, sunlight, and medicines.

When repotting orchids, the old soil will be mixed with some new soil for planting, or it is not suitable to plant directly with the old soil.

Orchids are best to use pine needle soil, in the pine forest, there are no weeds or anything under the tree, only thick larch needles, the surface of the fallen leaves are brushed open, the following layer of loose and dark soil is the best, under the pot pad a layer of absorbent and light bottom stone (vermiculite, ceramite, etc.), when transplanting, pay attention to the root system of the orchid. It is normal to retreat the weeds at the beginning of the potting, and the diseased leaves can be cut off. If the spots are severe, and when the rainy season is hot and humid, water less and spray carbendazim.

The landlord wants to use stones, but also depends on what kind of stone, such as ceramsite, blue stone and other planting materials, one is convenient for drainage and ventilation, the second is to store water, in case of drying to adjust the humidity, three to these planting materials are very light in texture, no edges and corners, will not squeeze damage the root root, the root can grow freely in their crevices. You can't use ordinary pebbles or something, it's hard and heavy, and the roots of the orchid can't stretch in the middle.

Pine bark, oak bark, moss, peanut shells and other orchids can also be used, but the bark and peanut shells cannot be fresh, they must be sterilized and sealed for a year to rot (so that there is nutrition and there will be no germs or anything) in order to raise orchids. Moss can be used fresh, just wrap the root.

It is best to use loose, breathable and well-drained humus soil for orchid cultivation, and the soil I use is dug in the pine forest where orchids grow, as long as the surface layer, I feel that the effect is good. It is best not to use fresh honeycomb cinders, if you want to use them, you have to put them in a place where you can get rain for a period of time, otherwise they will burn the roots.

Try one each of weathered stone + decaying bark + humus.

<> need to provide loose and breathable slightly acidic soil next to the orchid when cultivating orchids, which is conducive to the growth of plants, and also need to provide sufficient scattered light for orchids to avoid direct sunlight, and also need to place them in a temperature environment of 16 to 24 degrees, and at the same time keep the plants warm in winter to avoid frost damage to orchids.

1. Soil conditions.

Orchids are suitable for growing in loose and breathable soil, so they need to mix humus and sand and gravel when breeding, and at the same time need to add some base fertilizer to the soil to provide sufficient nutrients for the plants, and also need to loosen the soil regularly, and keep the soil loose, which is conducive to the growth of orchids.

2. Lighting conditions.

Orchids like scattered light, but are afraid of strong light, so they need to provide sufficient scattered light exposure when breeding, and at the same time, when the light is strong in summer, it is necessary to do a good job of shading measures for the plants to avoid burning the orchid leaves, and in winter when the light is weak, it can be placed in indoor sunlight.

3. Temperature environment.

Orchids are suitable for growing in a temperature environment, and need to provide a temperature environment of 16 to 24 when breeding, which is conducive to the lush growth of plants, and when the temperature is higher than 30 degrees in summer, it is necessary to take cooling measures for orchids, and when it is lower than 5 degrees in winter, it is necessary to take warm measures to avoid frost damage to the plants.

4. Moisture conditions.

Orchids like moisture and are afraid of waterlogging, so they need to be provided with sufficient water when breeding, and they also need to do a good job of drainage measures for the plants to avoid soil water accumulation leading to the rot of orchid roots, and in winter the plants are dormant and the water demand decreases, so the orchids should be stopped watering at this time.

Orchids are fleshy roots, the pot must maintain good drainage performance, the soil is selected humus soil or soil with more corrosive substance, you can go to the flower shop to buy.

The best time to pot is in the spring of March and April or the autumn of October and November. Flower pots are selected with small mouths, deep pots, and large bottom holes, so that the mud is easy to dry, has good aeration, and is easy to root.

Although orchids like shade, but perennial shade will affect flowering, it is best to use shade in summer to prevent exposure to the sun, and then the orchid pot is turned every half a month, so that it can receive light on all sides and grow in a balanced manner.

Do not use tap water for watering, which will affect the acidity of the soil, and it is best to use rainwater or river water. Just wet the soil in two layers, don't water too hot and not too cold, and the temperature should be moderate.
