How to Boost Fragrance in Orchids? Master These Methods for a Stronger Scent

1.Orchidsprefer partial shade, but they must not be placed in dark, lightless spots. Otherwise, because they cannot receive light for photosynthesis over the long term, they grow poorly and have no way to produce the organic matter needed to supply the nectary glands with the nectar that creates fragrance, so even if they bloom, they will not be fragrant. They should be placed in a spot with strong light but some shade, and in winter they should be placed in a spot with ample sunlight, with the pot turned once every half month so that all sides receive light.

2. Repot in a timely manner to keep the potting soil fertile. Apart from withholding fertilizer during the intense heat, severe cold, and around the flowering period, apply a dilute phosphorus-based fertilizer solution every half month, so that the orchid has the ability to supply the nectary glands with nectar and to accumulate and store it.

3. Orchids' cold tolerance is relatively poor.Cymbidium goeringii、Cymbidium faberimust be kept above 3°C,Cymbidium ensifolium、Cymbidium kanranmust be kept above 10°C. Otherwise, they are prone to frost damage, which affects flowering, or they may barely bloom but the nectar freezes and cannot release fragrance.

4. In greenhouses, flower rooms, or shade sheds where many orchids are placed or planted, care should be taken to isolate different varieties. They must not be mixed together or planted together, to avoid pollen mixing and changing the original good fragrance-releasing performance. Orchids should be kept away from toilets, kitchens, and other places with a high possibility of contamination, so that contamination does not cause the nectary glands to malfunction and decline, affecting fragrance release.

5. Orchids are susceptible to bacterial diseases such as anthracnose, leaf spot, and black rot, and viral diseases such as black spot and necrosis. They are also vulnerable to attack by scale insects, red spider mites, whiteflies, and others. If these are not promptly eliminated and treated, the orchids will suffer from numerous injuries and illnesses and become unable to accumulate nutrients to supply nectar production.
