What should you pay attention to when fertilizing orchids? Keep these points in mind

Growing flowers now should be different from growing flowers a few years ago. Today, the new-style apartments in rural and urban areas are decorated in a rather grand way, and potted flowers are meant to add atmosphere and color indoors and outdoors. Flower pots, growing media, and fertilizers should meet hygiene requirements. We do not advocate using organic fertilizers, such as various seed meals, fish scraps, hair, etc. Unless these materials are already very thoroughly decomposed, it is best not to use them. Based on years of experience, using these organic fertilizers very easily attracts ants, earthworms, and centipedes. If there are consecutive rainy days, they may also attract slugs and snails, and they easily breed mites. Not only are they harmful toorchids, they are also truly unsanitary and unsightly. We advocate usingorchidspecialty fertilizers. These fertilizers all come with detailed instructions and are easy to master. Some compound chemical fertilizers used in rural areas have inaccurate formulas, and some have unclear instructions, so they are not suitable for use. We introduce several commonly used and relatively inexpensiveorchidspecialty fertilizers for orchid enthusiasts' reference. "Lanjun Wang" produced by Sichuan Chengdu Huayi Technology Development Company is an ideal synthetic liquid fertilizer with a moderate price that can stimulate roots, stimulate buds, and grow strong plants. It is an orchid specialty fertilizer recognized by Mr. Wu Yingxiang after investigation. It is convenient to use, has no peculiar smell, and is a harmless fertilizer. After years of trials by many people, spring and summer orchids using this fertilizer have a high seedling emergence rate, grow well, and have no side effects. According to the instructions, this fertilizer can be applied once every 7-10 days in spring, summer, and autumn, and can also be applied on sunny days in winter, beneficial and harmless. The amount used can be according to the regulation of one bottle cap added to eight jin of water, or even a bit more dilute. Huabao No. 1-5 produced in Taiwan, China is a powdered fertilizer. Different numbered fertilizers are used according to the orchid variety and the different stages of growth and flower promotion. The price is still acceptable. If it is a small orchid nursery with 50-60 pots, you can still buy some hormone-type fertilizers such as those for promoting roots, buds, and flowers (boric acid can be used). However, these fertilizers are relatively expensive, but when applied to famous varieties, they can achieve relatively good results. If hormone-type chemicals are used, be sure not to use too much, otherwise orchids growing too fast are prone to virus damage, causing losses. If virus damage is found, application should be stopped immediately, light should be gradually increased, phosphorus and potassium fertilizers should be applied more, and the plants should be isolated from healthy plants. For tallorchid plants, apply bone meal to increase phosphorus and potassium fertilizers and a small amount of trace elements such as calcium, magnesium, zinc, and iron. Bone meal fertilizer should be purchased from a rubber processing plant. Bone meal fertilizer produced by small local plants has a bad smell and is not suitable for use. Bone meal after rubber processing has very fine particles and can simply be scattered on the pot surface. It can gradually seep down with watering and be absorbed by the roots. It is purely a harmless fertilizer. Potassium dihydrogen phosphate should always be kept on hand. If "Lanjun Wang" is used for fertilizing, apply potassium dihydrogen phosphate once every two applications.Orchid plantswill grow sturdy and are also likely to sprout flower buds. Potassium dihydrogen phosphate is very convenient to apply. Prepare a liquid at about one part per thousand, and it can be used both for spraying leaves and watering roots. Its fertilizer effect is both fast and good. Using potassium dihydrogen phosphate has only benefits and no harm for orchids. After years of observation, it is both economical and practical, truly a rare find. Fertilizer can be used in allfour seasonsof the year. In spring, beforeCymbidium goeringiibolts, nitrogen fertilizer should be applied so that the flower scapes grow tall and the flowers bloom large. Petal-type flowers cannot lack potassium. If only nitrogen fertilizer is used and water is not withheld, the flowers may have long bases. If potassium and trace elements are sufficient and water is withheld in time, petal-type flowers as round as copper coins can bloom. After the flowers are cut off, both cymbidiums and cymbidium orchids should return to normal fertilizing. You can try commercially available imported bud-promoting agents and rooting agents, once every seven days, alternating with dilute fertilizer sprayed on leaves and poured into pots. Continue until the new seedlings have rooted, then switch back to regular fertilizer. After the Beginning of Autumn, the weather turns cooler. Apply phosphorus and potassium fertilizers and imported flower-promoting fertilizers alternately to the leaves so that cymbidiums and cymbidium orchids can produce more winter buds and promote normal flowering next spring. In addition, attention must be paid to applying heat-protection fertilizer and cold-protection fertilizer at the right time. Two or three days before the arrival of high temperatures in midsummer, depending on the weather forecast, apply a mixed phosphorus and potassium fertilizer once; during the hot period, with a cycle of about ten days, when it turns cooler intermittently (such as rainy or typhoon days), phosphorus and potassium fertilizer can be applied immediately. For cold-protection fertilizer, it is best to add a portion of bone meal when repotting in autumn. One week before freezing, phosphorus and potassium fertilizer should be applied intermittently to makeorchid plantsmore cold-resistant. Diseased and weak seedlings should be isolated and placed in a safe spot; heavy fertilizer will kill them. (Guan Wenchang, Zhu Hexing)
