When Do Orchids Bloom? A Full Guide to Fertilizing Taboos

Orchids are a very famous type of flower with a great many varieties, and they are grown in many parts of our country. Orchids symbolize elegance and purity, so potted orchids are deeply loved by many flower growers. So when do orchids usually bloom? What are the fertilizing taboos?

1. When do orchids usually bloom?

The blooming period of any plant is related to climate and temperature, and orchids are no exception. Generally speaking, different varieties bloom at different times.

1. Cymbidium sinense: the blooming period is usually from October to March of the following year.

2. Cymbidium goeringii: its blooming period is usually from January to March.

3. Cymbidium faberi: its blooming period is usually from March to May.

4. Cymbidium ensifolium: it has strong vitality and fears neither cold nor heat. It can be seen blooming from May to December.

2. What are the fertilizing taboos for orchids?

Fertilizers used for orchids fall into 3 categories: organic fertilizers, inorganic fertilizers and biological bacterial fertilizers. The advantages of organic fertilizers are that they contain complete nitrogen, phosphorus and potassium, have sufficient fertility, have a long-lasting effect, and can improve the soil; the disadvantages are that they are unsanitary, smell bad, easily spread pathogens and breed pests. The advantages of inorganic fertilizers are that there is a wide choice, they are convenient to apply, take effect quickly, have no odor and carry no pathogens; the shortcoming is that they are not easy to master, and long-term application will cause the soil to become compacted and hardened. Biological bacterial fertilizers are made with the latest technology and have a positive promoting effect on the growth and development of orchids. So what are the fertilizing taboos for orchids?

1. Do not fertilize weak orchids

For newly planted orchids, old and weak orchids, and orchids that have already suffered a serious illness, we should fertilize with care, and more often than not it is recommended not to fertilize, because these orchids have weak resistance, and if fertilized, it is very easy for them to be unable to absorb it, and it may even cause fertilizer damage to the orchids. It is better to wait until the orchids have grown stronger, and then fertilize to give them a boost!

2. Do not fertilize at high temperatures

At high temperatures the absorption capacity of orchids also weakens, and some varieties of orchids even go dormant at high temperatures, so we should not fertilize during high temperatures. Not only is it prone to rotting or stunting, but in serious cases, a perfectly good orchid may, because it cannot absorb the fertilizer, turn yellow and wilt, and finally die.

3. Do not fertilize on rainy days

If orchids grown outdoors are fertilized on rainy days, it is easy to cause fertilizer damage. The absorption capacity of orchids weakens on rainy days, and if they cannot absorb it in time, it will put a burden on the orchids, and the root system will also be affected by the fertilizer, so it is not recommended to fertilize orchids grown outdoors on rainy days.

4. Do not fertilize after flower buds appear

The rule of not fertilizing after flower buds appear does not mean that no fertilizer at all can be applied right after the buds emerge. Generally, from the time the flower buds emerge from the soil to about 3 cm, until just before the flowers open normally, fertilizing is not recommended.

5. Do not fertilize during the dormant period

This point is very similar to not fertilizing in a high-temperature environment, and it is also because the orchid root system does not absorb nutrients during the dormant period, so we must never fertilize orchids during the dormant period.
