What Are the Reasons Why An Orchid Isn’t Blooming?
The reason that an orchid isn’t blooming is that it may not be the right blooming time; check whether the plant is mature enough. If everything is okay, note that insufficient light, nutrient deficiency, improper day or night temperature fluctuations, and low humidity can stop the blooms.
– It’s Not the Right Time
Orchids produce flowers during a specific season; orchids produce flowers once a year during the blooming period. It usually lasts two to three months, but the exact duration varies from specie to specie.
In other months, they stay dormant or focus on vegetative growth. So, when do orchids bloom indoors and outdoors? Each specie has its specific blooming season. Moth orchids like winter to spring, while Dendrobiums prefer February to June, and this is why knowing the kind of orchid you have and when it blooms is important for you.
Additionally, the age of the orchid also decides about blooming. If your orchid plant is less than a year old, it likely needs to mature enough to produce buds. But questions or worries like “My orchid hasn’t bloomed in 3 years, ” are another aspect that you must consider.
It is because almost every orchid becomes an adult within two to three years. So, if it is not developing any buds, it means there is a problem we are discussing.
– Light is Not Enough
Suitable lighting conditions are critical for smooth flowering. If less light falls on orchid leaves, the photosynthesis rate will decline. As a result, there won’t be enough energy within the plant to produce buds and develop them into flowers, and the plant won’t have the right needs to start blooming.
– Incorrect Watering Practices
Another reason your orchid isn’t blooming is water stress, and in such a manner, adding more or less water can hurt the plants, which impacts bud formation. Even if a bud appears, improper watering makes it less likely to bloom into a healthy flower.
For instance, if you are watering more than what they need, this is what will make the potting medium soggy and causes root suffocation. As a result, the water and nutrient absorption slow down and ultimately stop. When this happens, the orchid will show poor growth with no flowers.
Similarly, keeping the potting medium dry can also affect flowering. Orchids need water to perform every internal function, which maintains their health. This is why you must be aware that having a water shortage can impact these functions, which will weaken the plant.
Furthermore, water is needed to uptake critical nutrients as well. Therefore, not adding it in the right quantities will keep the orchid nutrient stressed and deprive it of a chance to bloom during the growing season.
– Unsuitable Night Temperature
Orchids need the temperature to be in the desirable range to flower. Each species has different requirements, but one thing is certain: the night temperature should be around 5 to 15 degrees Fahrenheit less than during the day.
If the day and night temperature stays the same, the orchid plant cannot bloom even if it is flowering season. To confirm, use digital thermometers to be more sure, because it is during the night when the weather is cooler than it would have the ability to bloom, but in such a case when the temperature is unsuitable, you will see the plant not as prosperous.
– Lack of The Needed Minerals in the Potting Medium
Is your orchid growing new leaves but no flowers? It happens when there is an abundance of nitrogen in the potting medium and a lack of phosphorus and potassium.
There is no denying that minerals are crucial for blooming. But you should add them in the right amounts so that the orchid gains the maximum benefit. Adding those fertilizers that are low in phosphorus and potassium causes a deficiency of these nutrients in the orchid.
As a result, the metabolism slows down, which creates an energy shortage. An orchid low on energy cannot produce buds and bloom them into flowers. Check the fertilizer bottles or packages and confirm the phosphorus and potassium ratio.
– Humidity Is Lower Than 30 Percent
Orchids naturally like humidity to be somewhat high, which should be between 50 and 70 percent. Most of them can also tolerate up to 40 percent. But if it drops below 30, the plants will feel stressed, which will weaken the plant in the long run.
The dry air will force the orchid to evaporate faster. When this happens, the roots absorb more water to avoid drought stress. But still, the water intake cannot keep pace with evaporation, and the plants will become dehydrated.
As a result, such orchids cannot produce buds in the right way. Even if it does, the buds will wilt with time. To confirm if low humidity is the culprit, use a hygrometer or humidity gauge to know about the moisture levels in the air.
– Roots Are Stressed
The last main reason behind the non-blooming of orchids is unhealthy roots. We all know that roots are crucial for any plant because they intake nutrients and water. So, don’t expect the orchid to produce flowers when they feel uncomfortable.
Root bound is a common root problem that occurs when the volume in the pot is less. In this condition, roots start circulating within the potting medium and come upward. As a result, the nutrient and mineral uptake get affected.
Root burn is another issue that orchids face when you over-add fertilizers. The excessively filled minerals in the potting medium create nutrient toxicity, which burns the roots. Furthermore, doing this also lowers the pH, which makes the nutrients unavailable.
In addition, keeping the potting mix wet for a long time can cause root rot disease. In this, roots decompose or rot, as the name suggests, and you smell a foul odor from the potting medium. With time, the disease spreads to the stem and leaves, reducing the chances of flowering to nothing.
How To Make Your Orchid Produce Blooms?
To make your orchid produce blooms, provide optimal lighting conditions, maintain day/night temperature, and keep humidity above 40 percent. Furthermore, focus on water and fertilizer management to ensure the orchid stays healthy and feels encouraged to produce lots of flowers.
Orchids do not bloom constantly. They produce flowers for a few weeks, and most enter dormancy. However, you can prolong the blooming period by providing suitable lighting conditions, adding adequate water, maintaining appropriate temperatures, and keeping humidity high according to the type of orchid and what it would prefer when growing.
– Focus on Lighting Conditions
Orchids grow flower buds when they get more than 12 hours of bright and indirect light. East-facing windows are the best choice because the sun rays coming through them are soft. Outdoors, under the roof, or awning are the most suitable spots where the light will come in a bright way but not excessively but indirectly.
– Maintain the Right Temperatures
You should ensure the nighttime temperatures are lower than the daytime. If you put the orchids outside, bring them inside, as the home’s temperature is normally lower. Furthermore, you can also rely on devices such as thermostats, air circulators, air conditioners, or even a humidifier, to lower the temperature at night.
If you see mitten-shaped roots sprouting out of the medium, it indicates that the orchid will bloom again. Furthermore, heavy foliage and new growth are other signs of flowering. When buds start forming on a flower spike, and this way it would start to develop properly and would have better chances of blooming again.
– Give Mineral Doses the Right Way
If you are growing orchids for flowers, you must keep in mind to always choose the right fertilizer. A balanced one in a 20:20:20 nitrogen, phosphorous, and potassium ratio is the best. For smooth blooming, companies have also manufactured bloom boosters.
Add fertilizers every week in small doses to avoid root burn. Diluting it with water is also preferable to lessen the chances of nutrient toxicity. Note that you should not add them when it is time for bud development. But if a bloom booster specifically mentions it, then follow the instructions.
Also, an orchid reblooms when you give a mineral dose at the end of the flowering season. Long story short, by adding fertilizers correctly, you can see lots of blooms repeatedly.
– Optimal Water Management
When watering, you should never forget “orchid care.” The latter is what is going to give you the right grip, for instance, overwatering and under watering can stop the flower buds from emerging. Therefore, keeping the potting medium adequately moist is important.
For this, you should keep checking the potting medium. When it dries out, only then add water. You can pour one-fourth cup of water, use two to three ice cubes, or spray the medium directly. If you unintentionally make the medium soggy, drain out the extra liquid.
– Keep the Humidity Above 40 Percent
Another critical plant care measure to see blooms is maintaining the humidity levels. They should be above 40 percent, at least if you have moth orchids. To add moisture to the air, and this is why you must try to use a humidifier, spray the orchid every day, and even you should try to place the orchids on humidity trays.
Put a humidity gauge next to your orchid when you take these measures. Turn off the humidifier or remove the orchid from the tray whenever humidity exceeds 40 percent.
– Do Some Pruning
Beginners often ask us, how to make an orchid grow a new spike to see more blooms growing in the right way. It’s true that the fresher the flower spikes, the more blooms you will see. That is why we recommend pruning right before the start of the blooming period.
In this, you cut the flower spike slightly above the node using shears. Furthermore, removing sick leaves and aerial roots is also a part of orchid pruning. After you cut these parts, the orchid will get a fresh start and will likely produce many flowers in the season.
– Repot When Needed
Repotting to a bigger pot with a fresh potting mix is also a great strategy to see more orchid flowers. It relieves the roots as there will be fewer chances of roots being bound in a big container. That’s why you will see more growth after giving a plant a new home.
Conclusion
Here, we have explained simple ways how to solve these problems and force the orchid to bloom, which are:
- Orchids don’t bloom when they face problems like insufficient light exposure, water stress, lack of nutrients, temperature issues, and low humidity.
- To ensure your orchids get maximum bright and indirect light. And try to add one-fourth cup of water whenever the potting medium becomes dry.
- Add a balanced fertilizer or bloom booster to increase the chances of blooming.
- Use humidifiers and humidity trays to raise the humidity levels.
- Pruning and repotting orchids before the blooming period also helps.
It’s that simple to make orchids produce more blooms, and you will have a better grip at growing the plant.
