Why Isn't My Orchid Fragrant? Causes and Solutions

Orchids have a long history in our country and are one of the top ten famous flowers of our country. The ancients have always regarded them as a symbol of nobility and elegance. As everyone knows, the charm of orchids lies in their delicate fragrance. But many friends feel quite wronged, because the orchids they grow turn out to have no fragrance at all. What is going on here? Below, the editor will help everyone find the reasons.

1. Insufficient light

Orchids are shade-loving by nature and afraid of sunlight exposure. This has led many growers to believe that their growth does not need sunlight, and they even think orchids are afraid of sunlight. So they keep them indoors or in shaded places for long periods, which means they get no light and cannot carry out photosynthesis, and therefore cannot produce fragrance.

Solution: We need to continuously adjust its light duration. In spring and winter, the two seasons when sunlight is milder, it can be given all-day sunlight. In summer and autumn, when sunlight is stronger, we can place it in a semi-shaded environment and try to avoid the times when sunlight is strongest.

2. Variety degeneration

After many years of selection and cultivation, inferior varieties of orchids have been eliminated, and most of those remaining are superior varieties. However, with changes in the growing environment, or when cultivated mixed together with other plants, orchids will be affected by them to some extent. During the flowering period, they may be disturbed by the pollen of other plants, which may cause their flowers to be unable to release fragrance.

Solution: To avoid variety degeneration, do not grow them mixed together with other non-fragrant varieties or other flowering plants, so as to prevent pollen interference.

3. Temperature

Many orchid varieties bloom mostly in the colder seasons of spring and winter. Because the temperature is relatively low, the nectar in the flowers will be affected. When the temperature falls below 0 degrees, the nectar freezes, and naturally it will not release fragrance. When the temperature rises again, the nectar thaws, and the fragrance will continue to be released.

Solution: Regulate the growing temperature. When they bloom in low-temperature seasons, keep the temperature above 5 degrees or higher.

4. Lack of fertilizer

Orchids like fertilizer. If fertility is insufficient, it easily causes the leaves to turn yellow, and during the bud stage it can even cause flowers to drop, affecting their growth and development. As a result, the nectaries naturally cannot produce nectar, so there is no fragrance.

Solution: During the growing period, apply more phosphorus and potassium fertilizer. After the Autumn Equinox, fertilizer should also be applied in time to ensure nutrient supply for the plant.

The above is the content on why orchids are not fragrant. I believe that after reading the above, everyone should have found the reason why their own orchids are not fragrant. We hope this can help everyone.
