Analysis of Why Orchids Are Not Fragrant 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 purity 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 not be fragrant at all. What is going on here? Below, the editor will help everyone find the reasons.

1. Insufficient light

Orchids by nature prefer shade and fear sunlight exposure. This makes many growing friends think that their growth does not need sunlight, and some even think they fear sunlight, so they keep them indoors or in shaded places for a long time. As a result, without light they cannot carry out photosynthesis, and therefore cannot produce fragrance.

Solution: We should continuously adjust its light duration. In spring and winter, the two seasons when sunlight is relatively mild, it can receive all-day sunlight, while in summer and autumn the sunlight is relatively strong, so we can place it in a semi-shaded environment and try to avoid the time when sunlight is strongest.

2. Variety degeneration

After many years of seed selection and cultivation, inferior varieties of orchids are eliminated, and most of those remaining are fine varieties. However, as the growing environment changes, or when they are mixed-cultivated 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 mix-cultivate them with other non-fragrant varieties or other flowering plants, so as to prevent pollen interference.

3. Temperature

Many orchid varieties mostly bloom in the seasons with lower temperatures in spring and winter. Because the temperature is relatively low, the nectar in the flowers will be affected by it. When the temperature is below 0°C, the nectar freezes, so naturally it will not release fragrance. When the temperature rises again, the nectar thaws, and the fragrance will continue to be released.

Solution: Adjust the growing temperature. When blooming in low-temperature seasons, control the temperature above 5°C or higher.

4. Lack of fertilizer

Orchids like fertilizer. If the fertility is insufficient, it can easily cause the leaves to turn yellow, and at the bud stage it may even cause flowers to drop, affecting their growth and development. As a result, the nectar glands 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 the plant's nutrient supply.

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