Fertilizing orchids requires care; mastering the correct method is key
Fertilizing orchids requires care. Mastering the correct fertilizing method can make orchids produce more shoots and bloom frequently, with vigorous growth. In summary, fertilizing orchids is about precision, not quantity, and should be considered comprehensively in light of factors such as the condition of the orchid's shoots and its growth characteristics. Any fixed, unchanging fertilizing method is incomplete. Lanxiangge, drawing on years of orchid-growing experience, summarizes this from three dimensions:
1. How to fertilize from the perspective of the four seasons: Throughout the year, spring is the period of vigorous growth and reproduction for orchids, high summer temperatures are unfavorable for growth, autumn brings the stage of strengthening the shoots, and winter is the dormant period. Once this pattern is understood, the question of fertilizing can be studied. The whole year's work depends on a good start in spring; in spring, more fertilizer can be applied to encourage orchids to produce more shoots and strong shoots. In summer, with frequent rain and high temperatures, the growth of orchid plants is inhibited, so at this time do not apply much fertilizer, otherwise high-temperature fertilizer burn is likely. In autumn, orchids are in the shoot-strengthening stage, storing nutrients for winter and flowering, so at this time topdressing should be done promptly to ensure the orchids' growth, and phosphorus fertilizer in particular should be on the higher side. In winter, orchids are in the dormant period, and basically no fertilizer needs to be applied, so they can overwinter safely.
2. How to fertilize from the perspective of the growth cycle: The orchid's important growth cycles differ in the types and methods of fertilization. The growth cycle is divided into three important stages: the shoot-producing stage, the flowering stage, and the dormant stage. Although different orchid varieties have different durations for these three stages, the growth pattern is consistent, and therefore the fertilizing method is also the same. For orchids in the shoot-producing stage, relatively more fertilizer can be applied, especially by strengthening the supply of nitrogen fertilizer. For the flowering stage, fertilizer should be applied in advance; generally, two months before the flowering stage, the supply of phosphorus fertilizer should be increased, as phosphorus fertilizer can promote the growth of orchid buds and enhance the quality of orchid flowers. During the dormant stage, fertilizing is generally not recommended; orchids inherently prefer light, simple fertilizer, and especially during the dormant period, no fertilizer at all is perfectly fine.
3. How to fertilize from the perspective of fertilizer types: The fertilizers used for orchids include: chemical fertilizers, whose typical representative is monopotassium phosphate, generally used for foliar spraying to enhance leaf color and promote flowering; biological fertilizers, whose typical examples include clarified soybean water and clarified rice-washing water; when using these fertilizers, attention should be paid to sterilization and disinfection, and the concentration should be kept light and simple; slow-release compound fertilizers, whose typical representatives include Huakang and Osmocote; these fertilizers are characterized by long fertilizer efficacy and comprehensive nutrition, and are therefore recommended for use as a base fertilizer.
