In spring, orchid lovers are busy again, looking forward to the beloved orchids that will thrive and bloom beautifully this season. However, in the process of orchid maintenance, we may encounter some problems, such as the appearance of scorched tips in the orchid leaves. This not only affects the ornamental value of orchids, but may also affect the healthy growth of orchids. So, what is the reason for the scorching of orchid leaves, and how can it be avoided?
First of all, we need to understand that the scorched tip of orchid leaves is mostly caused by physiological causes, not by bacterial infection or pest infestation. This may have something to do with our conservation methods. For example, when it comes to watering, as we mentioned earlier, orchids can neither be too thirsty nor too waterlogged. Although spring is a rainy season, if we accidentally let the orchid potting soil accumulate too much water, the roots will easily rot, which will cause the old seedlings to be scorched. Therefore, when watering, we should do it at the right time and in the right amount to ensure that the potting soil is moist but not too wet.
In addition, fertilization is also a link that needs attention. Some flower lovers may think that applying more fertilizer can make orchids grow stronger. But in fact, too much fertilization will damage the root system of the orchid, causing water to flow backwards, causing scorching, which is manifested as new seedlings also scorching. Therefore, it is necessary to follow the principle of "thin fertilizer and frequent application" when fertilizing, and avoid applying too much fertilizer at one time.
In addition to watering and fertilizing, the choice of materials in the potting soil is also important. In order to save costs, some flower lovers may mix some uncooked organic matter, such as fresh wood chips, into the potting soil. During the fermentation process, these organic matter can burn off the crystal head at the root tip or consume the oxygen in the pot, causing a scorched tip. Therefore, when preparing potting soil, it is better to use a fully decayed material.
In addition, when turning pots, it is also necessary to pay attention to pruning rotten roots and keeping the plant wood clean. If the dead roots are not pruned or the planting wood is not clean, it will affect the growth and development of new roots, which in turn will cause new leaves to be scorched. In order to avoid this situation, we should completely remove the diseased roots and rotten roots when turning the pot, and add an appropriate amount of disinfectant to sterilize the potting soil when preparing the potting soil.
