Old orchid plants that take forever to grow roots? An orchid grower teaches you a reliable rooting method

Old orchid plants that take forever to grow roots have the "family back home" worried sick. Orchid growers say: this is the only reliable way!

Caring for orchids is a delightful thing. Especially when the orchids you grow yourself have lush leaves and branches and bloom with fragrant flowers, it is your most joyful moment. However, there is one situation where you cannot bear to throw the plant away, yet after planting it, it simply will not grow roots for the longest time - this is the old orchid plant. This kind of situation really worries the "family back home" (the people who care for the orchids) sick.

First, let us look at what causes this situation to occur. In fact, the main reasons why some orchid plants will not grow new roots for the longest time are the following: First, the plant is excessively old and weak, and because of repeated forcing of shoots, the plant has aged and is nearing the end of its life. Second, after the temperature rises, the leaves of this plant gradually turn yellow and withered from the leaf tips toward the leaf base and then drop off. Third, unsuitable light and temperature. If planted during the dormant period, after planting, if heat preservation and frost protection are inadequate, there will be mild frost damage; in spring, with continuous overcast and rain, there is little light and the temperature is on the low side.

There is also a lack of phosphorus. Especially when the substrate contains no organic phosphorus or mineral phosphorus, the plant body's energy transfer and storage are both poor. It can also be caused by excessive hormones. If a high concentration of growth promoter or dwarfing agent has been used, the plant body's growth factors are inhibited. It can also be harmed by infection from fungi and insect pests. Over-abundant water and fertilizer. Because after planting there is no improvement for a long time, water and fertilizer are often applied and sprayed frequently, so the substrate has too much water and fertilizer, poor aeration, and the pseudobulbs already show slight signs of wrinkling.

When encountering this kind of situation, as orchid growers, we should adjust it in this way. Usually, use a 1500-2000 times dilution of medical aspirin (sodium acetylsalicylate) to water it once, and spray the leaves twice. In most cases, within 1 month, you can see it begin to grow roots. If it is failure to grow roots caused by invasion and infection by fungi and insects, the success rate of rescue is not high.
