Why don't orchids bloom?

No flowering due to own reasons

Small orchid seedlings

Only adult orchids can bloom, but the ones you just bought are likely to be orchid seedlings, which are still in the reproductive stage and their roots have not yet grown. It takes two years to slowly provide nutrients and grow into a pseudobulb before it can bloom.

Bulb aging

After years of division, the bulbs grow and age, the new roots are not fully developed, and the absorption of nutrients is also limited. At this time, the plant does not have enough nutrients to bloom, so it is necessary to repot it in time to promote root growth.

Weak plants

For orchids to bloom, they need good roots and leaves. The key to good roots is ventilation and water; the key to good leaves is light and fertilizer, and the two must be unified and balanced. If the orchid is too fat, it will not bloom; if it is too thin, it will not bloom either.

Failure to bloom due to incorrect maintenance

Unsuitable light temperature

Due to less sunlight, the accumulation of organic matter in the orchid plant is limited, which cannot meet the needs of growth, let alone flowering.

If the temperature is too low, the plants are easily frozen and will not bloom even if they do not die. Only by ensuring suitable temperature, increasing temperature difference and accumulating sufficient nutrients can orchids be promoted to bloom.

Improper fertilization

Improper fertilization here refers to the fertilization season and the combination of fertilizer elements. If you continue to fertilize in late autumn and winter, excess nutrients will stimulate the orchid to escape dormancy and reduce the vernalization effect. However, if the elements of fertilizer are unbalanced or there is too much nitrogen fertilizer, the plant will grow too tall, the leaves will become thick, and the growth and even differentiation of flower buds will be inhibited.

The correct time for fertilizing should be from April to July, with nitrogen fertilizer as the main fertilizer and phosphorus and potassium fertilizer as the auxiliary fertilizer; from July to August, with phosphorus and potassium fertilizer as the main fertilizer and nitrogen fertilizer as the auxiliary fertilizer.

Impact of pests and diseases

Orchids will not bloom if they are infected with diseases or insect pests. If anthracnose, leaf spot and whitefly are not prevented and eradicated in time, they will affect the growth of orchids and cause them to not bloom.

In daily maintenance, you should set a schedule and spray the pesticide regularly. Don't wait until you see pests and diseases to treat them, because it will be too late.
